    MEMORANDUM OPINION
    The plaintiff, Edith Ann Higgins, brings this civil action against the defendant, Andrew
    Saul, in his official capacity as Commissioner of the Social Security Administration (“SSA”) (the
    “Commissioner”), challenging the Commissioner’s decision denying her claim for disability
    insurance benefits pursuant to 42 U.S.C. § 405(g) (2018). See generally Complaint (“Compl.”).
    On January 20, 2016, this Court “referred [the case] to a Magistrate Judge for full case
    management up to, but excluding, trial[,] . . . includ[ing], with respect to any dispositive motions,
    preparation of a report and recommendation.” Order at 1 (Jan. 20, 2016), ECF No. 3.
    Thereafter, the plaintiff filed a Motion for Judgment of Reversal (“Pl.’s Mot.”), and the
    Commissioner filed the Defendant’s Motion for Judgment of Affirmance and in Opposition to
    Plaintiff’s Motion for Judgment of Reversal (“Def.’s Mot.”). On March 3, 2017, the Magistrate
    Judge issued a Report and Recommendation recommending that the Court deny the plaintiff’s

    Andrew Saul is the current Commissioner of the Social Security Administration, see Commissioner, Social
    Security, https://www.ssa.gov/agency/commissioner.html (last visited Aug. 12, 2019), and the Court therefore
    substitutes him for former Acting Commissioner Nancy A. Berryhill as the proper party defendant pursuant to
    Federal Rule of Civil Procedure 25(d).
    motion and grant the defendant’s motion. See Report and Recommendation (the “Report” or “R
    & R”) at 1. Currently before the Court are the Plaintiff’s Objections to the Report and
    Recommendation of the Magistrate Judge (“Pl.’s Objs.”). Upon careful consideration of the
    parties’ submissions, 2 the Court concludes that it must grant in part and deny in part the
    plaintiff’s motion for a judgment of reversal and deny the defendant’s motion for a judgment of
    affirmance.
    I.    BACKGROUND
    A.      Statutory and Regulatory Background
    The Social Security Act provides disability insurance benefits and supplemental security
    income to qualifying individuals with a disability. See 42 U.S.C. §§ 423(a)(1), 1381, 1381a.
    The Act defines “disability” as an “inability to engage in any substantial gainful activity by
    reason of any medically determinable physical or mental impairment which can be expected to
    result in death or which has lasted or can be expected to last for a continuous period of not less
    than [twelve] months.” 
    Id. § 423(d)(1)(A).
    “With certain exceptions not relevant here, an
    individual is disabled ‘only if [her] physical or mental impairment or impairments are of such
    severity that [she] is not only unable to do [her] previous work but cannot, considering [her] age,
    education, and work experience, engage in any other kind of substantial gainful work which
    exists in the national economy.’” Butler v. Barnhart, 
    353 F.3d 992
    , 997 (D.C. Cir. 2004)
    (alterations in original) (quoting 42 U.S.C. §§ 423(d)(1)(A), 1382c(a)(3)(B)).
    2
    In addition to the documents already identified, the Court considered the following submissions in rendering its
    decision: (1) the Plaintiff’s Memorandum of Points and Authorities in Support of Plaintiff’s Motion for Judgment of
    Reversal (“Pl.’s Mem.”); (2) the Defendant’s Memorandum in Support of Her Motion for Judgment of Affirmance
    and in Opposition to Plaintiff’s Motion for Judgment of Reversal (“Def.’s Mem.”); (3) the Plaintiff’s Response to
    Motion for Judgment of Affirmance and Reply to Motion for Judgment of Reversal (“Pl.’s Resp.”); (4) the
    Defendant’s Response to Plaintiff’s Objections to the Magistrate Judge’s Report and Recommendation (“Def.’s
    Resp.”); and (5) the Plaintiff’s Reply to Defendant’s Response to Plaintiff’s Objections to the Magistrate’s Report
    and Recommendation (“Pl.’s Reply”).
    2
    The Commissioner uses a five-step process to determine whether a claimant is disabled,
    see 20 C.F.R. § 416.920, with “[t]he claimant carr[ying] the burden of proof on the first four
    steps,” 
    Butler, 353 F.3d at 997
    . At the first step, the claimant must demonstrate that she is not
    engaged in “substantial gainful activity,” 20 C.F.R. § 416.920(a)(4)(i), which is defined as work
    that “[i]nvolves doing significant and productive physical or mental duties; and [ ] i[s] done (or
    intended) for pay or profit,” 
    id. § 404.1510.
    At the second step, the claimant must establish that
    she has a “severe medically determinable physical or mental impairment that meets the [twelve-
    month] duration requirement.” 
    Id. § 416.920(a)(4)(ii).
    An impairment is “severe” if it
    “significantly limits her physical or mental ability to do basic work activities.” 
    Id. § 416.920(c).
    At the third step, if the claimant can establish that her “impairment(s) [ ] meets the duration
    requirement” and “meets or equals one of [the] list[ed] [impairments] in appendix 1” of the
    SSA’s regulations, the Commissioner “will find that [she] [is] disabled.” 
    Id. § 416.920(a)(4)(iii),
    (d). If the claimant does not make this showing, the Commissioner’s inquiry moves on to the
    fourth step, which requires the claimant to demonstrate that her impairment prevents her from
    performing her “past relevant work,” 
    id. § 416.920(a)(4)(iv),
    (e), which is defined as “work that
    [a claimant] ha[s] done within the past [fifteen] years, that was substantial gainful activity, and
    that lasted long enough for [the claimant] to learn to do it,” 
    id. § 404.1560(b)(1).
    “Once a
    claimant has carried the burden on the [ ] four[th] step[], the burden shifts to the Commissioner
    on step five to demonstrate that the claimant is able to perform ‘other work.’” 
    Butler, 353 F.3d at 997
    (quoting 20 C.F.R. §§ 404.1520(f), 416.920(f)).
    To evaluate a claim at steps four and five, the Commissioner must “assess and make a
    finding about [the claimant’s] residual functional capacity based on all the relevant medical and
    other evidence in [the claimant’s] case record.” 20 C.F.R. § 416.920(e). A claimant’s residual
    3
    functional capacity “is the most [the claimant] can do despite [physical and mental] limitations”
    resulting from her “impairment(s)[] and any related symptoms.” 
    Id. § 416.945(a)(1).
    The
    “[residual functional capacity] assessment must [ ] identify the [claimant]’s functional limitations
    or restrictions and assess his or her work-related abilities on a function-by-function basis.” SSR
    96–8p, 
    1996 WL 374184
    , at *1 (July 2, 1996). Specifically, the residual functional capacity
    assessment “must address both the remaining exertional and nonexertional capacities of the
    individual.” 
    Id. at *5.
    “Exertional capacity addresses an individual’s limitations and restrictions
    of physical strength and defines the individual’s remaining abilities to perform each of seven
    strength demands: [s]itting, standing, walking, lifting carrying, pushing, and pulling.” 
    Id. “Nonexertional capacity
    considers an individual’s ability to perform the following work-related
    functions: postural activities like stooping and climbing; manipulative activities like reaching
    and handling; visual activities; communicative activities; and mental activities.” Davis v.
    Berryhill, 
    272 F. Supp. 3d 154
    , 171 (D.D.C. 2017) (citing SSR 96–8p, 
    1996 WL 374184
    , at *6).
    “The [SSA] regulations describe a two-step process for evaluating symptoms[.]” SSR
    96–7p, 
    1996 WL 374186
    , at *2. “First, the adjudicator must consider whether there is an
    underlying medically determinable physical or mental impairment(s)[] . . . that could reasonably
    be expected to produce the individual’s pain or other symptoms.” 
    Id. “Second, .
    . . the
    adjudicator must evaluate the intensity, persistence, and limiting effects of the individual’s
    symptoms to determine the extent to which the symptoms limit the individual’s ability to do
    basic work activities.” 
    Id. “In evaluating
    the intensity and persistence of [a claimant’s]
    symptoms, . . . [the Commissioner] consider[s] all of the available evidence, including [the
    claimant’s] medical history, the medical signs and laboratory findings, and statements about how
    [the] symptoms affect [the claimant],” and “determine[s] the extent to which [the] alleged
    4
    functional limitations and restrictions due to pain or other symptoms can reasonably be accepted
    as consistent with the medical signs and laboratory findings and other evidence.” 20 C.F.R.
    § 404.1529(a). Statements about how the symptoms affect the claimant may include opinions
    “from acceptable medical sources,” 
    id. § 404.1527(a)(1);
    “[o]pinions from medical sources who
    are not acceptable medical sources and from nonmedical sources,” 
    id. § 404.1527(f)(1);
    and
    statements from the claimant herself or other individuals, see 
    id. § 404.1529(c)(4).
    Acceptable
    medical sources include “treating sources,” such as the claimant’s own physician who has
    “provided [the claimant] with medical treatment or evaluation and who has, or has had, an
    ongoing treatment relationship with [the claimant],” 
    id. § 404.1527(a)(2);
    nontreating sources,
    such as a physician who has examined the claimant “but does not have . . . an ongoing treatment
    relationship with [the claimant],” 
    id. § 404.1527(a)(2);
    or “nonexamining source[s],” 
    id. § 404.1527(c)(3),
    meaning physicians “who ha[ve] not examined [the claimant] but provide[] a
    medical or other opinion,” 20 C.F.R. § 404.1502 (2012). At the time the plaintiff in this case
    applied for benefits, nonacceptable medical sources included “nurse practitioners, physicians’
    assistants, naturopaths, chiropractors, audiologists, and therapists.” 20 C.F.R. § 404.1513(d)(1)
    (2012). 3 If the claimant requests a hearing, the Commissioner may also consider assessments
    regarding the claimant’s residual functional capacity “made by . . . State agency medical . . .
    consultants . . . based on their review of the evidence in the case record.” 
    Id. § 404.1513(a)(5).
    “[W]henever [an] individual’s statements about the intensity, persistence, or functionally
    limiting effects of pain or other symptoms are not substantiated by objective medical evidence,
    the [Commissioner] must make a finding on the credibility of the individual’s statements based
    3
    Since the plaintiff in this case applied for benefits, “the [SSA] regulations have been amended and for claims filed
    after March 27, 2017, a ‘Licensed Advance Practice Registered Nurse, or other licensed advanced practice nurse
    with another title’ may be considered an ‘acceptable medical source.’” Troy v. Colvin, 
    266 F. Supp. 3d 288
    , 295
    (D.D.C. 2017) (quoting 20 C.F.R. §§ 404.1502(a), 416.902(a)).
    5
    on consideration of the entire case record.” SSR 96–7p, 
    1996 WL 374186
    , at *2. “The reasons
    for the credibility finding must be grounded in evidence and articulated in the determination or
    decision.” 
    Id. For example,
    [i]t is not sufficient to make a conclusory statement that ‘the individual’s allegations
    have been considered’ or that ‘the allegations are (or are not) credible[.]’ . . . The
    determination or decision must contain specific reasons for the finding on
    credibility, supported by evidence in the case record, and must be sufficiently
    specific to make clear to the individual and to any subsequent reviewers the weight
    the [Commissioner] gave to the [ ] statements and the reasons for that weight.”
    
    Id. “The administrative
    review process consists of several steps.” 20 C.F.R. § 404.900(a).
    First, the Commissioner makes an “[i]nitial determination” on a claimant’s application. 
    Id. § 404.900(a)(1).
    Second, “[i]f [a claimant] [is] dissatisfied with an initial determination, [she]
    may ask [the Commissioner] to reconsider it,” 
    id. § 404.900(a)(2),
    and third, “[i]f [a claimant]
    [is] dissatisfied with the reconsideration determination, [she] may request a hearing before an
    administrative law judge” (“ALJ”), 
    id. § 404.900(a)(3).
    Finally, “[i]f [a claimant] [is]
    dissatisfied with the decision of the [ALJ], [she] may request that the Appeals Council review the
    decision.” 
    Id. § 404.900(a)(4).
    Once these four steps are completed, the Commissioner “ha[s]
    made [his] final decision.” 
    Id. § 404.900(a)(5).
    “Any individual, after [a] final decision [by] the
    Commissioner[,] . . . may obtain review of such decision by a civil action commenced within
    sixty days after the mailing . . . of notice of such decision[,] . . . [and] [s]uch action may be
    brought in the district court of the United States for the judicial district in which the plaintiff
    resides.” 42 U.S.C. § 405(g). The district court may affirm, modify, or reverse the decision of
    the Commissioner with or without remanding it for a rehearing. See 
    id. 6 B.
         Factual Background and Procedural History
    The plaintiff filed her application for disability benefits on June 28, 2012. See
    Administrative Record (“AR”) 18. In her application, she “alleg[ed] disability beginning April
    30, 2012,” AR 18, based on “chronic pulmonary restrictive disease, sleep apnea, and diabetes,”
    see AR 61.
    In support of her application, the plaintiff completed and submitted a “Function Report”
    and a “Work History Report.” See AR 184–205. In the Work History Report, the plaintiff
    reported that, in the past fifteen years, she had held positions as a pharmacy technician at a clinic
    and a retail business, a customer service representative at a call center and a utility business, and
    a quality assurance agent at a call center. See AR 187. In the plaintiff’s Function Report, which
    is a questionnaire regarding “[h]ow [her] . . . conditions limit[ed] [her] activities,” the plaintiff
    reported that she “ha[d] periods when [she] c[ould not] concentrate,” “g[ot] out of breath
    quickly,” “sometimes ha[d] a hard time breathing,” AR 198, and was “unable to stay awake for
    long periods of time,” AR 199. She also reported that she “often t[ook] longer to complete tasks
    because [she was] tired [and] sleepy” and could pay attention only for “about [thirty] minutes.”
    AR 203. As to her daily activities, the plaintiff reported that she “[d]ress[ed] [her] minor child,
    d[id] household chores, [and] cook[ed][,] taking frequent breaks between every task.” AR 199.
    Additionally, she reported that she prepared “[c]omplete meals” three to four times per week, AR
    200, went outside two to three times per week, see AR 201, “read[], watch[ed] [television, and
    used the] computer” daily, “[s]p[oke] with people on the phone and computer” four to five times
    per week, and went to church weekly, AR 202. She also indicated that she was able to pay bills,
    count change, handle a savings account, and use a checkbook and money orders. See AR 201.
    7
    The plaintiff’s adult daughter, Lula Barnes, also completed a Function Report regarding
    the plaintiff’s limitations. See AR 209–16. Barnes reported that the plaintiff “[wa]s unable to
    concentrate for long periods of time, [ ] los[t] her train of thought often,” AR 209, and “ha[d]
    trouble completing task[s] because she falls asleep,” AR 214. Barnes also reported that the
    plaintiff did “everything necessary” for her minor child, who at the time was almost two years
    old, AR 210, prepared “[c]omplete meals” weekly, AR 211, did “[c]leaning and laundry” daily
    “with frequent breaks,” AR 211, and “read[], wr[ote], play[ed] cards, play[ed] computer games,
    [and] watch[ed] [television]” daily but was “prone to failing asleep while doing” those activities,
    AR 213.
    To evaluate the plaintiff’s claim, the SSA obtained various medical records documenting
    the plaintiff’s medical history. Specifically, it obtained progress notes from Laura Worby, a
    certified nurse practitioner (“Nurse Worby”), recording Nurse Worby’s treatment of the plaintiff
    from January 2011 to June 2012. See AR 365–461. The records reflect Nurse Worby’s findings
    that the plaintiff had the following conditions: type II diabetes, hypertension, morbid obesity,
    emphysema, a personal history of tobacco use, and postablative hypothyroidism. See AR 366.
    Nurse Worby’s records also reflect that she treated these conditions by, inter alia, prescribing
    various medications, see, e.g., AR 366–67, advising the plaintiff on her diet, see, e.g., AR 373
    (reporting that she “encouraged [the plaintiff] to . . . monitor diet[] [and] to limit soda intake”),
    and “counsel[ing] [the plaintiff] on the dangers of tobacco use and urg[ing] [her] to quit”
    smoking cigarettes, AR 367. Additionally, Nurse Worby’s records reflect that the plaintiff was
    hospitalized at the Washington Hospital Center from January 30 to February 2, 2012, due to
    “emph[y]s[e]ma exacerbation, pneumonia, [and] heart failure” and was “discharged on [two]
    liters of continuous [oxygen].” AR 378.
    8
    On August 17, 2012, the SSA obtained a medical opinion from Dr. Earl Nicholas, a state
    agency consultant. See AR 77. Dr. Nicholas’s report acknowledges receipt of the plaintiff’s and
    Barnes’s Function Reports, the plaintiff’s Work History Report, and the pre-June 2012 medical
    records. See AR 71–72. Dr. Nicholas’s report makes various factual findings regarding the
    plaintiff’s medical history and concluded that the plaintiff has exertional, postural, and
    environmental limitations. See AR 74–75. As to the plaintiff’s exertional abilities, Dr. Nicholas
    found that the plaintiff could frequently lift or carry less than ten pounds, stand or walk with
    normal breaks for a total of two hours in an eight-hour workday, sit with normal breaks for a
    total of six hours in an eight-hour workday, and push or pull with no limits. See AR 74. As to
    the plaintiff’s postural abilities, he concluded that the plaintiff could frequently balance and
    stoop and occasionally climb ramps or stairs, kneel, crouch, and crawl, but could never climb
    ladders, ropes, or scaffolds. See AR 74. Finally, as to the plaintiff’s environmental abilities, Dr.
    Nicholas concluded that the plaintiff could be exposed to extreme cold, wetness, and noise on an
    unlimited basis, but must “[a]void even moderate exposure” to extreme heat, humidity, vibration,
    fumes, odors, dusts, gases, poor ventilation, and hazards. AR 75. Ultimately, however, Dr.
    Nicholas concluded that the plaintiff’s “limitations d[id] not prevent [her] from performing work
    [she] ha[d] done in the past as a customer service representative.” AR 77. Accordingly, he
    concluded that the plaintiff was not disabled. See AR 77. 4
    The Commissioner rendered an initial decision denying the plaintiff’s claim on August
    20, 2012. See AR 18. Thereafter, the plaintiff sought reconsideration of the Commissioner’s
    4
    The Court notes that the record contains another opinion from Dr. Nicholas, which is signed by him on the same
    date as the opinion cited above and contains the same findings regarding the plaintiff’s limitations but concludes that
    the plaintiff cannot perform her past work and is disabled. See AR 61–68. Because the ALJ did not consider this
    alternative opinion, see AR 23 (citing AR 74–75), and because neither the plaintiff nor the defendant asserts that the
    ALJ should have considered it or that the opinion undermines the ALJ’s conclusion, the Court need not consider it
    in evaluating the plaintiff’s objections to the Magistrate Judge’s Report.
    9
    decision. See AR 92. In response, the SSA obtained a second medical opinion from Dr.
    Jacqueline McMorris, another state agency consultant. See AR 78–86. In addition to the
    materials received by Dr. Nicholas, Dr. McMorris received various medical records that the SSA
    obtained from the Washington Hospital Center in August and December 2012. See AR 79. Dr.
    McMorris affirmed Dr. Nicholas’s findings as to the plaintiff’s abilities, see AR 82–83, as well
    as his conclusion that the plaintiff’s limitations did not prevent her from performing her past
    work as a customer service representative, see AR 85. Accordingly, Dr. McMorris also
    concluded that the plaintiff was not disabled. See AR 85. Upon reconsideration of his initial
    decision denying the plaintiff’s claim, taking into account the second opinion from Dr.
    McMorris, the Commissioner again denied the plaintiff’s claim on January 11, 2013. See AR
    18. Then, on February 13, 2013, the plaintiff filed a written request for a hearing, which the
    Commissioner granted. See AR 18.
    Prior to her administrative hearing, the plaintiff submitted additional evidence, including
    a “Sleep Disorders Residual Functional Capacity Questionnaire” completed by Nurse Worby on
    March 7, 2014. AR 539, 542. Nurse Worby reported on the questionnaire that the plaintiff
    experienced “daytime sleep attacks” that typically occurred four to five times per day and lasted
    forty-five minutes each time, AR 539, as well as “side effects of medications” in the form of
    “[d]rowsiness/sedation,” AR 540. Nurse Worby also found that the plaintiff’s “[d]iabetic
    neuropathy interfere[d] with standing.” AR 542. Due to these issues, Nurse Worby concluded
    that the plaintiff would likely need to take four unscheduled breaks to rest during an average
    workday, with each break lasting an average of forty-five minutes. See AR 541. Nurse Worby
    also concluded that the plaintiff could sit continuously for only thirty minutes at a time and for
    less than a total of two hours in an eight-hour workday with normal breaks, and stand
    10
    continuously for only twenty minutes at a time and for less than two hours in an eight-hour work
    day with normal breaks. See AR 540.
    On April 23, 2014, an ALJ conducted a hearing on the plaintiff’s claim, which included
    testimony from the plaintiff and an impartial vocational expert. See AR 18. As to her
    symptoms, the plaintiff testified, inter alia, that she “was falling asleep . . . more often, even
    though [she was] using [her] [continuous positive airway pressure (‘CPAP’)] machine at night,”
    and that, in January 2013, she “fell asleep in the middle of [ ] writing [a grocery] list.” AR 53.
    She further testified that “the only reason . . . [Barnes was] still living at home [with her] [wa]s
    because . . . [she] f[e]ll asleep so eas[il]y [and she] d[id not] want anything to happen to her”
    then-three-year-old daughter. AR 43–44. She also testified that she used oxygen “all day every
    day,” AR 38, “[b]ecause if [she] want[ed] to do anything at all [she] ha[d] to have the oxygen
    on,” AR 52. She further testified that she used a travel oxygen tank that weighed “maybe seven
    pounds,” as well as a “stationary” tank that she used at home. AR 52. The plaintiff also testified
    that she “originally applied [for disability benefits] when [her medical providers] first told [her]
    that [she] was going to be on [ ] oxygen[,] . . . because that’s what everybody said [she] was
    supposed to do since [she] was [ ] on [ ] oxygen.” AR 56.
    As to her daily activities, the plaintiff testified that she “g[o]t [her] three-year-old
    [daughter] ready for school,” AR 46, and walked her daughter four blocks to school, see AR 47,
    “normally . . . stop[ping] a couple of times going up [a] hill,” AR 50. She also testified that she
    was “able to . . . bath[e] [her]self and dress [her]self” but that it was “a slow process,” and that
    she was also able to “wash dishes, . . . wipe off [ ] the furniture[,] and [ ] [i]f [she] t[ook] [her]
    time[,] . . . sweep the floors,” AR 49, and do laundry, so long as there were no detergents or
    products present that “irritate[d] [her] lungs and [ ] breathing,” AR 48. The plaintiff further
    11
    testified that she would “try to prepare dinner” and “get it started, [but] normally somebody else
    ha[d] to finish it.” AR 47. She additionally testified that she watched television for about two or
    three hours a day, see AR 54, and played memory games on the computer for “[m]aybe an hour”
    each day, AR 54, but that she did not read, talk to friends on the telephone, or spend time going
    out with friends, see AR 55. She also testified that she could lift and carry about fifteen pounds,
    see AR 48, and sit down comfortably for “[a]bout [ ] half an hour,” AR 50.
    The vocational expert testified that the plaintiff’s past work as a pharmacy technician was
    “light” and her past work as a customer service representative and quality assurance agent was
    “sedentary.” AR 57. In response to hypothetical questions from the ALJ, the vocational expert
    opined that if the plaintiff were limited to standing or walking approximately two hours and
    sitting approximately six hours in an eight-hour workday, she could perform her past sedentary
    positions, but if she were limited to sitting for two hours in an eight-hour workday, she could not
    perform any of her past relevant work or any other work. See AR 58–59. In response to
    questioning from the plaintiff’s representative, the vocational expert also testified that, “[i]f [a]n
    individual is off task for [fifteen] to [eighteen] percent of the workday,” the individual could not
    maintain any work in the national economy. AR 59.
    On August 21, 2014, the ALJ issued a decision determining that the plaintiff is not
    disabled and denied the plaintiff’s claim. See AR 25. Following the five-step analysis outlined
    above, the ALJ concluded at step one that the plaintiff “ha[d] not engaged in substantial gainful
    activity since April 30, 2012, the alleged onset date” of her disability. AR 20. The ALJ then
    concluded at step two that the plaintiff “ha[d] the following severe impairments: hypertension,
    diabetes, COPD, sleep apnea, and obesity,” but concluded at step three that none of those
    impairments, alone or in combination, “me[t] or medially equal[ed] the severity of one of the
    12
    listed impairments in 20 CFR Part 404, Subpart P, Appendix 1.” AR 20. The ALJ then assessed
    the plaintiff’s residual functional capacity and concluded that she
    ha[d] the residual functional capacity to perform sedentary work as defined in 20
    C[.]F[.]R[.] [§] 404.1567(a) except lifting up to [ten] pounds occasionally, standing
    or walking approximately two hours, sitting approximately six hours in an eight[-]
    hour workday; pushing and pulling are unlimited except as shown for lifting and
    carrying; never crawling or climbing ladders, ropes, or scaffolds; frequently
    balancing, occasionally climbing ramps and stairs, stooping, crouching, and
    kneeling; and . . . avoid[ing] even moderate exposure to extreme heat, humidity,
    vibration, fumes, odors, dust, gases, poor ventilation, and hazards such as
    machinery and heights.
    AR 21.
    In further assessing the plaintiff’s residual functional capacity, the ALJ concluded that
    although the plaintiff’s “medically determinable impairments could reasonably be expected to
    cause [her] alleged symptoms” of “being unable to stay awake, periods when she c[ould not]
    concentrate, getting out of breath quickly, and sometimes having a hard time breathing,” the
    plaintiff’s “statements concerning the intensity, persistence[,] and limiting effects of these
    symptoms [we]re not entirely credible.” AR 21. Specifically, the ALJ concluded that “[s]everal
    elements in the record call[ed] into question the credibility of the [plaintiff’s] allegations,”
    namely, the plaintiff’s “testi[mony] that she applied for disability when she began using oxygen,
    because that is what everyone told her she was supposed to do,” that she “ha[d] not been
    compliant with her treatment,” AR 21, and that “her activities of daily living [went] beyond
    limitations that preclude work,” AR 22. With respect to the plaintiff’s daily activities, the ALJ
    observed that the plaintiff
    cares for her children and grandchildren, performs personal care, prepares complete
    meals several times a week, cleans, and does laundry. She goes outside two to three
    times a week, walks, uses public transportation, shops in stores and online, handles
    money, reads, watches television, uses her computer, attends church, and
    communicates on the telephone and computer four to five times a week.
    AR 22.
    13
    Additionally, the ALJ considered, but did not credit, Barnes’s statements “that the
    [plaintiff] is unable to concentrate for long periods of time, [ ] loses her train of thought, and
    [that] her ability to stay awake ha[d] been decreasing.” AR 23. The ALJ reasoned that the
    plaintiff’s “activities [ ] of preparing complete meals, reading, writing, playing cards and
    computer games, and watching television all require the ability to maintain concentration for the
    duration of those activities.” AR 24.
    As to the medical opinion evidence in the record, the ALJ “g[ave] [Dr. Nicholas’s and
    Dr. McMorris’s] opinions great weight, because th[o]se medical doctors reviewed the
    [plaintiff’s] medical records, and they have experience relating impairments to limitations.” AR
    23. The ALJ also concluded that “the evidence regarding the [plaintiff’s] level of functioning is
    consistent with the[ir] opinions, and the[] opinions are consistent with the evidence at the hearing
    level.” AR 23 (citation omitted). By contrast, she assigned Nurse Worby’s opinion “very little
    weight” for several reasons, including that Nurse Worby “is not an acceptable medical source,”
    “her opinion concerning the claimant’s limitations is grossly inconsistent with the evidence of
    record, including the claimant’s acknowledged activities and level of functioning,” and her
    “opinion concerning the extent of limitations on sitting and reported number of sleep attacks are
    not consistent with either the medical record or any statement regarding the claimant’s activities
    of daily living.” AR 24.
    Finally, at step four, the ALJ concluded that the plaintiff was “capable of performing
    [her] past relevant work as a customer service representative and quality assurance agent.”
    AR 24. In reaching this conclusion, the ALJ found that, “[i]n comparing the [plaintiff’s] residual
    functional capacity with the physical and mental demands of this work, . . . the [plaintiff] [wa]s
    able to perform [the work] as actually and generally performed.” AR 25. Additionally, the ALJ
    14
    observed that the “work does not require the performance of work-related activities precluded by
    the [plaintiff’s] residual functional capacity.” AR 24. Accordingly, the ALJ concluded that the
    plaintiff was not disabled. See AR 25.
    On August 21, 2014, the plaintiff requested that the Appeals Council review the ALJ’s
    decision; however, the Appeals Council “denied [her] request for review” on November 10,
    2015. AR 1. The plaintiff then filed the instant case on January 7, 2016. See Compl. at 1. On
    January 20, 2016, this Court referred the plaintiff’s case to a Magistrate Judge for full case
    management. See Order at 1 (Jan. 20, 2016), ECF No. 3. Thereafter, the plaintiff filed her
    motion for judgment of reversal, see Pl.’s Mot. at 1, and the defendant filed his motion for
    judgment of affirmance, see Def.’s Mot. at 1.
    On March 3, 2017, the Magistrate Judge issued her Report assessing the parties’ motions.
    See R & R at 1. In her Report, the Magistrate Judge found that “[t]he ALJ’s [residual functional
    capacity] determination was supported by substantial evidence,” 
    id. at 6,
    because, inter alia,
    “there was no significant evidentiary gap in the administrative record” and the ALJ “properly
    evaluated and discredited [the] [p]laintiff’s allegations of daytime ‘sleep attacks’ and her need
    for oxygen,” 
    id. at 11.
    Accordingly, the Magistrate Judge recommended that this Court deny the
    plaintiff’s motion and grant the defendant’s motion. See 
    id. at 12.
    On April 15, 2017, the
    plaintiff filed her objections to the Magistrate Judge’s Report, see Pl.’s Objs. at 1, which are the
    subject of this Memorandum Opinion.
    II.   STANDARDS OF REVIEW
    A.     Objections to Report and Recommendation
    Federal Rule of Civil Procedure 72(b) governs the Court’s resolution of objections to a
    magistrate judge’s report and recommendation on dispositive motions. The Rule provides that
    15
    the Court “must determine de novo any part of the magistrate judge’s disposition that has been
    properly objected to. The [Court] may accept, reject, or modify the recommended disposition;
    receive further evidence; or return the matter to the magistrate judge with instructions.” Fed. R.
    Civ. P. 72(b)(3). In their objections, the parties may not present new issues or arguments to the
    Court; rather, “only those issues that the parties have raised in their objections to the Magistrate
    Judge’s report will be reviewed by this [C]ourt. . . . Furthermore, objecting to only certain
    portions of the Magistrate Judge’s report ‘does not preserve all the objections one may have.’”
    Aikens v. Shalala, 
    956 F. Supp. 14
    , 19–20 (D.D.C. 1997) (citations omitted). And, “when a
    party makes conclusory or general objections, or simply reiterates his original arguments, the
    Court reviews the [r]eport and [r]ecommendation only for clear error.” M.O. v. District of
    Columbia, 
    20 F. Supp. 3d 31
    , 37 (D.D.C. 2013) (Walton, J.) (citation and internal quotation
    marks omitted).
    B.     The Commissioner’s Disability Determination
    Under 42 U.S.C. § 405(g), a court reviewing a benefits determination by the
    Commissioner is “confined to determining whether the [Commissioner’s] decision . . . [was]
    supported by substantial evidence in the record.” Brown v. Bowen, 
    794 F.2d 703
    , 705 (D.C. Cir.
    1986). “Substantial-evidence review is highly deferential to the agency fact-finder.” Rossello ex
    rel. Rossello v. Astrue, 
    529 F.3d 1181
    , 1185 (D.C. Cir. 2008) (citation omitted). With respect to
    the Commissioner’s factual determinations, the “substantial evidence” requirement mandates that
    the Commissioner’s findings be supported by “such relevant evidence as a reasonable mind
    might accept as adequate to support a conclusion.” Richardson v. Perales, 
    402 U.S. 389
    , 401
    (1971) (citation and internal quotation marks omitted). The standard requires “more than a
    scintilla, but less than a preponderance of the evidence.” Evans Fin. Corp. v. Dir., Office of
    16
    Workers’ Comp. Programs, 
    161 F.3d 30
    , 34 (D.C. Cir. 1998) (citation and internal quotation
    marks omitted). With respect to the Commissioner’s legal rulings, the reviewing court must
    uphold the Commissioner’s legal “determination if it . . . is not tainted by an error of law.”
    Smith v. Bowen, 
    826 F.2d 1120
    , 1121 (D.C. Cir. 1987). The “[C]ourt shall review only the
    question of conformity” by the Commissioner to the SSA’s regulations as well as “the validity of
    such regulations.” 42 U.S.C. § 405(g). The Court’s review “‘calls for careful scrutiny of the
    entire record’ to determine whether the [Commissioner], acting through the ALJ, ‘has analyzed
    all evidence and has sufficiently explained the weight he has given to obviously probative
    exhibits.’” Simms v. Sullivan, 
    877 F.2d 1047
    , 1050 (D.C. Cir. 1989) (citations omitted).
    However, the Court may only consider the grounds proffered by the agency in its decision, as
    post hoc rationalizations by an agency will not suffice. See 
    Butler, 353 F.3d at 1003
    n.5. And,
    the Court “may not reweigh the evidence presented to it[,] . . . [or] replace the [Commissioner’s]
    judgment concerning the weight and validity of the evidence with its own.” Turner v. Colvin,
    
    964 F. Supp. 2d 21
    , 28 (D.D.C. 2013) (alterations in original) (quoting Davis v. Heckler, 566 F.
    Supp. 1193, 1195 (D.D.C. 1983)).
    III.   ANALYSIS
    The plaintiff raises three objections to the ALJ’s decision and the Magistrate Judge’s
    Report. First, she argues that the ALJ inadequately considered the plaintiff’s medical evidence
    submitted after June 2012 (the “post-June 2012 medical evidence”) by “us[ing] h[er] own lay
    judgment” to assess that evidence. See Pl.’s Objs. at 4 (citation omitted). Second, she argues
    that “the ALJ failed to perform a function by function analysis of the frequency and duration of
    [the plaintiff’s] sleep attacks and her need for daytime oxygen.” 
    Id. at 8.
    Third, she argues that
    “the ALJ erred by relying on [ ] stale non-examining medical opinions from [ ] physician[s] who
    17
    had only a small fraction of her medical records to [ ] review,” 
    id. at 4
    (citation omitted),
    referring to the opinions of state agency consultants Dr. Nicholas and Dr. McMorris. The Court
    will address each argument in turn.
    A.     The ALJ’s “Lay Judgment” Analysis of the Post-June 2012 Medical Evidence
    The plaintiff argues that the ALJ erred by “us[ing] h[er] own lay judgment to” evaluate
    the post-June 2012 medical evidence, 
    id. at 4
    (citation omitted), because an ALJ cannot “review
    raw medical data without the assistance of any medical expert,” 
    id. at 5;
    see Pl.’s Mem. at 24
    (arguing that the ALJ had “an affirmative obligation to obtain medical opinion evidence
    regarding” the post-June 2012 medical evidence). The defendant responds that “the ALJ’s duty
    to obtain an updated medical opinion was not triggered in this case because the ALJ had all the
    information necessary to make a disability determination and the ALJ did not find that [Nurse]
    Worby’s [post-June 2012] treatment notes would change the state agency doctors’ findings.”
    Def.’s Resp. at 2 (citations omitted).
    The Court must reject the plaintiff’s argument that the ALJ improperly considered the
    post-June 2012 medical evidence by evaluating it herself rather than obtaining a medical opinion
    regarding it. The SSA’s regulations expressly require ALJs to evaluate “all the relevant medical
    and other evidence” in making their residual functional capacity assessment, 20 C.F.R.
    § 416.920(e), “including [a claimant’s] medical history[] [and] the medical signs and laboratory
    findings,” 
    id. § 404.1529(a).
    The plaintiff does not identify, nor is the Court able to locate, any
    regulation requiring that an ALJ obtain a medical opinion regarding such evidence. See
    Goodman v. Colvin, 
    233 F. Supp. 3d 88
    , 105–06 (D.D.C. 2017) (“[T]here is ‘no requirement that
    an ALJ must always receive an updated report from the State medical experts whenever new
    medical evidence is available.’” (quoting Wilson v. Astrue, 331 F. App’x 917, 919 (3d Cir.
    18
    2009))). Rather, the regulations provide only that certain “[s]ituations [ ] may require [an ALJ to
    obtain] a consultative examination,” 20 C.F.R. § 404.1519a(b) (emphasis added), specifically,
    “to resolve an inconsistency in the evidence[] or when the evidence as a whole is insufficient to
    allow . . . a determination or decision on [the plaintiff’s] claim,” id.; see 
    id. (explaining that
    “needed medical evidence” may include “clinical findings, laboratory tests, a diagnosis, or
    prognosis”), and the plaintiff has not made a specific showing that such circumstances are
    present in this case, see Pl.’s Objs. at 5 (asserting only that, as a general matter, “non-doctors
    [cannot] review raw medical data without the assistance of any medical expert”); see also Turner
    v. Astrue, 
    710 F. Supp. 2d 95
    , 108 (D.D.C. 2010) (rejecting the plaintiff’s argument that the ALJ
    “failed to adequately develop the administrative record” by not obtaining additional medical
    opinion evidence because the plaintiff did “not argue that there [we]re any missing records or
    other relevant evidence that was not presented to the ALJ” and did not object to the record in the
    administrative proceedings); cf. Lauer v. Apfel, 
    245 F.3d 700
    , 704 (8th Cir. 2001) (concluding
    that an ALJ should have obtained “professional assistance” because evaluation of a claimant’s
    psychological impairments “was impossible without first obtaining [and interpreting] the results
    of three standardized psychological tests”). Thus, the Court cannot conclude that the ALJ’s
    evaluation of the post-June 2012 medical evidence was improper simply because the ALJ did not
    obtain a medical opinion evaluating that evidence.
    The plaintiff cites various decisions for the proposition that “the ‘substantial evidence’
    standard . . . requires that the ALJ’s [residual functional capacity] . . . be based more or less on
    some compelling piece of medical opinion evidence.” Pl.’s Objs. at 5; see citing Pl.’s Mem. at
    21–23 (collecting cases). However, these cases do not establish such a broad proposition.
    Rather, several of the cases cited conclude that medical opinion evidence is required only in
    19
    specific circumstances not demonstrated by the plaintiff here, such as to clarify the content of a
    “remarkably vague” medical opinion. See, e.g., Selian v. Astrue, 
    708 F.3d 409
    , 421 (2d Cir.
    2013). And, to the extent that these opinions suggest that a medical opinion is always required to
    relate “medical findings in the record . . . to specific residual functional capabilities,” Rosado v.
    Sec’y of Health & Human Servs., 
    807 F.2d 292
    , 293 (1st Cir. 1986), none of these decisions is
    controlling authority, and, as the plaintiff acknowledges, “there is significant disagreement”
    among courts on whether and when medical opinions are required, Pl.’s Mem. at 24; see, e.g.,
    Felton-Miller v. Astrue, 459 F. App’x 226, 230–31 (4th Cir. 2011) (medical opinion evidence
    never required).
    Thus, because the regulations do not expressly require an ALJ always to obtain a medical
    opinion, and because the plaintiff has not made a specific showing that the post-June 2012
    medical evidence required an opinion by a medical source, the Court cannot conclude that the
    ALJ erred simply by failing to obtain a medical opinion regarding the post-June 2012 medical
    evidence.
    B.     The ALJ’s Function-by-Function Analysis
    The plaintiff next argues that the ALJ erred by “fail[ing] to perform a function by
    function analysis of the frequency and duration of [the plaintiff’s] sleep attacks and her need for
    daytime oxygen.” Pl.’s Objs. at 8. The defendant responds that the ALJ “properly evaluated”
    the evidence regarding the plaintiff’s alleged sleep attacks and oxygen use and that “[t]he
    evidence is consistent with the [ALJ’s] [residual functional capacity] assessment for a range of
    sedentary work[][ ] that is performed primarily while seated.” Def.’s Resp. at 4. The Court will
    address the plaintiff’s alleged daytime oxygen use and sleep attacks in turn.
    20
    1.      Daytime Oxygen Use
    The plaintiff argues that the “[t]he ALJ’s failure to make any findings with regards to
    [her] need for supplemental daytime oxygen[] and failure to obtain any vocational evidence
    regarding that need for daytime oxygen requires remand.” Pl.’s Mem. at 33–34. Additionally,
    the plaintiff challenges the Magistrate Judge’s conclusion “that because the ALJ generally found
    [the plaintiff] to be less than fully credible, the ALJ must have concluded that she did not need
    daytime oxygen,” arguing that “[t]his [conclusion] amounts to post hoc speculation [because] the
    ALJ never connected the dots between h[er] credibility finding generally[] and [the] [p]laintiff’s
    specific need for daytime oxygen.” Pl.’s Objs. at 10. The defendant responds that “[t]he ALJ
    properly discredited [the] [p]laintiff’s allegation with respect to her need for oxygen” because
    she “thoroughly considered [the] [p]laintiff’s use of oxygen and cited [Nurse] Worby’s medical
    records, which contradicted [the] [p]laintiff’s hearing testimony that she used oxygen every day,
    all day, for the past two years.” Def.’s Resp. at 4 (internal citations omitted). The defendant
    further contends that records indicating that the plaintiff “continued to smoke and an October
    2013 medical record show[ing] that [the plaintiff] could walk on flat surfaces without oxygen
    after she lost [weight] . . . corroborated the ALJ’s decision that [the] [p]laintiff’s use of oxygen
    did not show an inability to work for no less than [twelve] consecutive months.” 
    Id. (internal citations
    omitted).
    Even assuming the plaintiff is correct that the ALJ erred by not expressly including in her
    residual functional capacity assessment any limitations related to the plaintiff’s alleged daytime
    oxygen use, the Court must find that any such error was harmless. See Mitchell v. Berryhill, 
    241 F. Supp. 3d 161
    , 166 (D.D.C. 2017) (“When the Commissioner’s decision evinces legal
    error, . . . the court should nonetheless affirm if the error was harmless.”). As already explained,
    21
    it is the plaintiff’s burden to prove at step four that her impairments prevent her from performing
    her past relevant work. See 
    Butler, 353 F.3d at 997
    . Here, the plaintiff does not provide, and the
    record does not appear to reflect, any evidence demonstrating that the plaintiff’s daytime oxygen
    use would prevent her from performing her past relevant work as a customer service
    representative or quality assurance agent. See AR 24. Notably, the plaintiff did not solicit any
    testimony from the impartial vocational expert establishing that her daytime oxygen use would
    limit her ability to perform the physical functions the ALJ identified as necessary for the
    plaintiff’s past relevant work. See AR 59–60; see also AR 21 (identifying the functions the
    plaintiff must perform as “lifting up to [ten] pounds occasionally[;] standing or walking
    approximately two hours[;] sitting approximately six hours in an eight hour work day;
    [unlimited] pushing and pulling . . . except as shown for lifting and carrying; . . . frequently
    balancing, [and] occasionally climbing ramps and stairs, stooping, crouching, and kneeling”).
    Nor did she provide any other evidence demonstrating that her daytime oxygen use would
    prevent her from performing these functions. Indeed, the plaintiff’s testimony before the ALJ
    suggests that her oxygen use imposed only minimal restrictions on her mobility. See AR 52
    (testifying that she carries a portable oxygen tank that is “not very” heavy and weighs “maybe
    seven pounds”). Moreover, the plaintiff did not identify any other functions required by her past
    relevant work that her oxygen use would prevent her from performing, and it is not otherwise
    apparent to the Court that her oxygen use would prevent her from performing these functions.
    See AR 40 (testifying that her customer service representative position required her to “answer[]
    the phone, talk[] to the customers, sometimes . . . train[] other representatives” and “[t]rouble
    shoot[] the [ ] customer[s’] problems”); AR 41 (testifying that her quality assurance agent
    position required her to “listen[] to [customer service] representatives[’] phone calls over a
    22
    device and grade[] their phone calls, ha[ve] conferences with the representatives about their
    scores, [and] . . . train[] them”).
    Thus, the plaintiff has not demonstrated that her daytime oxygen use prevents her from
    performing the requirements of her past relevant work, and accordingly, any failure by the ALJ
    to incorporate limitations regarding the plaintiff’s daytime oxygen use into the plaintiff’s residual
    functional capacity was harmless. See Barlow v. Comm’r of Soc. Sec., Civ. Action No. 17-756,
    
    2018 WL 2410361
    , at *7–8 (S.D. Ohio May 29, 2018), report and recommendation adopted, Civ.
    Action No. 17- 756, 
    2018 WL 3008208
    (S.D. Ohio June 15, 2018) (concluding that “even if the
    ALJ erred in failing to accurately capture all of [the] [p]laintiff’s visual limitations . . . , any such
    error was harmless” because the plaintiff “fail[ed] to explain how his visual impairments
    prevent[ed] him from performing his past [relevant] work”); see also Gallegos v. Astrue, Civ.
    Action No. 12- 0038-RFC, 
    2013 WL 1290199
    , at *10 (W.D. Tex. Mar. 25, 2013) (concluding
    that “[t]o the extent the ALJ erred by not including the limitations he found to be caused by [the]
    [p]laintiff’s mental impairment in his statement of [the] [p]laintiff's [residual functional
    capacity], such error [was] harmless” because the “[p]laintiff ha[d] not demonstrated that . . . a
    more detailed discussion of her depression or an explicit inclusion of accommodations supported
    by the ALJ’s findings would exclude [the p]laintiff’s past relevant work and shift the burden to
    the Commissioner at step five”).
    The plaintiff’s counterarguments are unpersuasive. She relies on the Western District of
    Virginia’s decision in Barnwell v. Colvin to support her position that the ALJ’s failure to include
    in her residual functional capacity limitations regarding her daytime oxygen use is reversible
    error. See Pl.’s Mem. at 34 (citing Barnwell v. Colvin, Civ. Action No. 13-19, 
    2014 WL 3890442
    , at *17 (W.D. Va. 2014)). In that case, the court concluded that the ALJ’s failure to
    23
    “include[] an accommodation for oxygen use in the [residual functional capacity] determination”
    was reversible error “[b]ecause there [wa]s no evidentiary basis in th[e] record to support a
    finding that a person requiring supplemental oxygen could perform the jobs” the ALJ found the
    plaintiff could perform. Barnwell, 
    2014 WL 3890442
    , at *17. However, this reasoning
    misstates the parties’ burdens at step four. It is not the ALJ’s burden at step four to demonstrate
    that the plaintiff can perform her past relevant work despite her limitations; rather, it is the
    plaintiff’s burden to demonstrate that she cannot perform her past relevant work given her
    limitations. As already explained, the plaintiff has not satisfied that burden here. Moreover, to
    the extent that the plaintiff now seeks to introduce the testimony of vocational experts in other
    cases cited by the court in Barnwell, see 
    2014 WL 3890442
    , at *17, the Court may not consider
    evidence outside of the administrative record developed below, see Jones v. Soc. Sec. Admin.,
    Civ. Action No. 16-2290 (CKK), 
    2018 WL 5817351
    , at *4 (D.D.C. Nov. 7, 2018) (“[T]he
    Court’s review is confined to the administrative record that was before the ALJ at the time of the
    decision[.]”). In any event, as Barnwell recognizes, there exists “some disagreement among
    vocational experts on the question.” 
    2014 WL 3890442
    , at *17. Thus, Barnwell does not
    support the plaintiff’s position.
    In the absence of any evidence demonstrating that the plaintiff’s daytime oxygen use
    prevents her from performing the functions required for her past relevant work, the Court cannot
    conclude that the ALJ’s incorporation of the plaintiff’s daytime oxygen use into the plaintiff’s
    residual functional capacity would have changed the ALJ’s conclusion at step four that the
    plaintiff is able to perform her past relevant work. Thus, the Court must conclude that any error
    committed by the ALJ with respect to the plaintiff’s daytime oxygen use was harmless.

    2.      Sleep Attacks
    The plaintiff argues that the ALJ should have “made [ ] specific [residual functional
    capacity] findings or conclusions about” her sleep attacks, particularly, findings regarding the
    “frequency and duration” of the sleep attacks, Pl.’s Objs. at 8, as well as “what limitations would
    be imposed during a sleep attack,” Pl.’s Resp. at 4; see Pl.’s Mem. at 33 (“[T]he ALJ’s mere
    finding that [the plaintiff] did not suffer sleep attacks at the frequency and duration suggested by
    [Nurse] Worby was insufficient to enable meaningful review of her decision and requires
    remand.”). She further argues that the Magistrate Judge’s conclusion that “[t]he ALJ was not
    required to evaluate [the] [p]laintiff’s sleep attacks because they were unsupported by objective
    evidence . . . is a[n] [impermissible] post hoc rationalization.” Pl.’s Objs. at 8. The defendant
    responds that the ALJ adequately “discussed the evidence of [the] [p]laintiff’s sleep apnea,”
    including by “not[ing] the sparse complaints of sleep apnea, . . . that [the] [p]laintiff could ‘sleep
    without difficulty’ at an August 2013 session” with Nurse Worby, and that Nurse “Worby’s
    opinion about the frequency of [the] [p]laintiff’s ‘sleep attacks’ was inconsistent with the
    record.” Def.’s Resp. at 3; see 
    id. at 4
    (“Despite Nurse Worby’s opinion that [the] [p]laintiff had
    four to five ‘sleep attacks’ per day, the records did not support such severity.” (internal citations
    omitted)).
    The Court must agree with the plaintiff that the ALJ did not adequately address the
    plaintiff’s allegations regarding her “sleep attacks” or her inability to stay awake. Although the
    ALJ addressed and assigned “very little weight” to Nurse Worby’s opinion regarding the
    plaintiff’s alleged sleep attacks, see AR 24, and the plaintiff does not directly challenge the
    ALJ’s assessment of what weight to assign that opinion, see Pl.’s Objs. at 8 (only challenging the
    ALJ’s reliance on the state agency consultants’ opinions); Pl.’s Mem. at 19, 33 (acknowledging
    25
    the ALJ’s decision to assign very little weight to Nurse Worby’s opinion but not explicitly
    challenging it), the ALJ did not adequately address the plaintiff’s remaining evidence of her
    sleep attacks, namely, the plaintiff’s and Barnes’s statements regarding the plaintiff’s inability
    “to stay awake for extended periods of time,” e.g., AR 199. With respect to the plaintiff’s
    statements regarding her inability to stay awake, the ALJ did not explicitly address these
    statements, but instead only generally found that all of the plaintiff’s “statements concerning the
    intensity, persistence[,] and limiting effects of [her] symptoms [we]re not entirely credible.” AR
    21. As already explained, the ALJ concluded that “[s]everal elements in the record call[ed] into
    question the credibility of the [plaintiff’s] allegations,” namely, that the plaintiff “testified that
    she applied for disability when she began using oxygen, because that is what everyone told her
    she was supposed to do,” that the plaintiff “ha[d] not been compliant with her treatment,” AR 21,
    and that “her activities of daily living [went] beyond limitations that preclude work,” AR 22.
    Additionally, with respect to Barnes’s statements “that the [plaintiff] is unable to concentrate for
    long periods of time, [that] she loses her train of thought, and [that] her ability to stay awake has
    been decreasing,” AR 23, the ALJ dismissed these statements because “the [plaintiff’s] activities
    [ ] of preparing complete meals, reading, writing, playing cards and computer games, and
    watching television all require the ability to maintain concentration for the duration of those
    activities,” AR 24.
    The Court cannot conclude that the evidence regarding the plaintiff’s daily activities
    suffices to support the ALJ’s decision to discredit the plaintiff’s and Barnes’s statements
    regarding the plaintiff’s inability to stay awake. Although an ALJ may properly consider a
    claimant’s “daily activities” when evaluating her statements regarding her symptoms, 20 C.F.R.
    § 404.1529(c)(3)(i), “ALJs must be especially cautious in concluding that daily activities are
    26
    inconsistent with testimony about [a claimant’s symptoms], because impairments that would
    unquestionably preclude work and all the pressures of a workplace environment will often be
    consistent with doing more than merely resting in bed all day,” Garrison v. Colvin, 
    759 F.3d 995
    ,
    1016 (9th Cir. 2014); see Smolen v. Chater, 
    80 F.3d 1273
    , 1284 n.7 (9th Cir. 1996) (“The Social
    Security Act does not require that claimants be utterly incapacitated to be eligible for
    benefits[.]”). And, “[a] claimant’s participation in the activities of daily living will not rebut his
    or her subjective statements of pain or impairment unless there is proof that the claimant engaged
    in those activities for sustained periods of time comparable to those required to hold a sedentary
    job.” Polidoro v. Apfel, No. 98 CIV. 2071 (RPP), 
    1999 WL 203350
    , at *8 (S.D.N.Y. Apr. 12,
    1999) (citation omitted); see Petty v. Colvin, 
    204 F. Supp. 3d 196
    , 207 (D.D.C. 2016)
    (explaining that an “ALJ should assess the ‘individual’s ability to do sustained work-related
    physical and mental activities in a work setting on a regular and continuing basis . . . [eight]
    hours a day, for [five] days a week, or an equivalent work schedule” (emphasis added)).
    Moreover, the ALJ cannot “ignore[] the limited fashion [in which] the plaintiff engages in . . .
    [her] activities.” Jackson v. Barnhart, 
    271 F. Supp. 2d 30
    , 36 (D.D.C. 2002).
    Here, the ALJ did not consider whether the plaintiff could perform any of her daily
    activities in a work setting for sustained periods of time without falling asleep, and the record
    does not appear to reflect that she could. Rather, the plaintiff’s testimony at her hearing was that
    she could watch television for only “[a]bout two[] [or] three” hours a day and play memory
    games on the computer for “[m]aybe an hour” per day, AR 54; see AR 55 (testifying that when
    on the computer, she “play[s] [memory] game[s]”), and, indeed, she testified that she would fall
    “asleep” while “looking at the [television],” AR 54, and that “some days [she] c[ould not] even
    play the [memory] games because [she could not] focus long enough to do what the game
    27
    actually want[ed] [her] to do,” AR 44. The plaintiff also represented in her Function Report that
    she “often t[ook] longer to complete tasks because [she was] tired and sleepy” and could only
    pay attention for “about [thirty] minutes” at a time. AR 203. Barnes confirmed many of these
    limitations, stating that the plaintiff “ha[d] trouble completing task[s] because she [would] fall[]
    asleep” and could pay attention for only “[thirty] min[ute]s [to] [one] hour.” AR 214. The
    absence of any findings or evidence to support that the plaintiff engaged in her daily activities for
    sustained periods of time seriously undermines the ALJ’s finding that the plaintiff’s daily
    activities indicated a lack of credibility. See Moe v. Berryhill, 731 F. App’x 588, 591–92 (9th
    Cir. 2018) (concluding that “[s]ubstantial evidence d[id] not support [an] ALJ’s conclusion that
    [the claimant’s] ability to complete some basic self-care activities was inconsistent with his
    testimony regarding symptoms from paranoia and flashbacks”).
    Additionally, “the ALJ ignored the limited fashion [in which] the plaintiff engages in
    some of the activities she described.” 
    Jackson, 271 F. Supp. 2d at 36
    . For example, although the
    plaintiff represented that she “[d]ress[ed] [her] minor child, d[id] household chores, [and]
    cook[ed],” she also represented that she “t[ook] frequent breaks between every task.” AR 199.
    And, although the plaintiff also represented that she prepared “[c]omplete meals,” AR 200, she
    claimed that she only did so three to four times per week, see AR 200, and both the plaintiff and
    Barnes reported that it took the plaintiff several hours to complete a meal, see AR 200 (the
    plaintiff stating that it took her “at least 2–3 hours” to prepare meals); AR 211 (Barnes stating
    that it took the plaintiff “3–4 hours” to prepare meals). Moreover, the plaintiff testified that she
    prepares only dinner, not breakfast or lunch, and that she “get[s] it started, [but] normally
    somebody else has to finish it.” AR 47. And, although the plaintiff reported that she reads, she
    testified at her administrative hearing that she no longer engaged in that activity. See AR 54–55.
    28
    Finally, although the plaintiff reported that she “[r]ead[,] watch[ed] [television], [and used the]
    computer” “daily,” she also reported that she was “falling asleep during these activities.” AR
    202. The ALJ’s apparent failure to consider this evidence of the plaintiff’s limitations provides
    yet another reason to find that her decision to dismiss the plaintiff’s and Barnes’s statements is
    not supported by substantial evidence. See 
    Jackson, 271 F. Supp. 2d at 37
    (concluding that
    “[t]he ALJ’s reliance on the [plaintiff’s daily] activities” in discrediting the plaintiff’s testimony
    “[wa]s misplaced” because “the ALJ’s evaluation indicates that the ALJ did not consider all of
    the relevant evidence in the record” regarding the plaintiff’s limitations).
    The ALJ’s remaining rationales for generally rejecting the plaintiff’s statements
    regarding her symptoms also do not suffice to dismiss the plaintiff’s allegations of her inability
    to stay awake for sustained periods. The ALJ’s observation that “the claimant has not been
    compliant with her treatment” because she, inter alia, “does not continuously use . . . her CPAP
    machine daily as instructed,” AR 21, does not justify the ALJ’s credibility finding. Although an
    ALJ may find a plaintiff’s
    statements . . . less credible if . . . medical reports or records show that the individual
    is not following the treatment as prescribed and there are no good reasons for this
    failure[,] [ ] the adjudicator must not draw any inferences about an individual’s
    symptoms and their functional effects from a failure to seek or pursue regular
    medical treatment without first considering any explanations that the individual
    may provide, or other information in the case record, that may explain infrequent
    or irregular medical visits or failure to seek medical treatment.
    SSR 96–7p, 
    1996 WL 374186
    , at *7; see 20 C.F.R. § 404.1530(c) (recognizing “[a]cceptable
    reasons for failure to follow prescribed treatment”). As the plaintiff correctly notes, see Pl.’s
    Mem. at 30, the record suggests that, in the period following the alleged onset date of the
    plaintiff’s disability, the plaintiff failed to use her CPAP machine for a period of time because
    she was “[un]able to get [the] correct mask” for her machine. AR 607; see AR 599 (Nurse
    Worby reporting that, as of April 2013, the plaintiff “[h]a[d] been without CPAP mask [for]
    29
    several months, tried to reorder, never received, insurance changed, may need to order again with
    new insurance”). The ALJ’s decision does not reflect that she considered this explanation.
    Consequently, the ALJ’s inference that the plaintiff’s statements about her symptoms were less
    credible because the plaintiff failed to use her CPAP machine was improper. See SSR 96–7p,
    
    1996 WL 374186
    , at *7. Moreover, although the ALJ cited other instances of the plaintiff’s
    noncompliance with her treatment, the ALJ did not connect these treatments to the plaintiff’s
    sleep apnea, which the plaintiff alleged is the cause of her inability to stay awake, see AR 43
    (testifying that her sleep apnea caused her “[c]onfusion, inability to concentrate, falling asleep if
    [she was] still for any length of time”), and the Court declines to speculate as to whether any
    such connection exists, see AR 21–22 (faulting the plaintiff for “continu[ing] to smoke
    cigarettes,” which “exacerbated her pulmonary impairment,” “turn[ing] off her oxygen to
    smoke,” and having a “diet . . . high in sugary foods and drinks”). Thus, the plaintiff’s
    noncompliance with her treatment also fails to support the ALJ’s credibility finding as to the
    plaintiff’s statements regarding her sleep apnea symptoms.
    Finally, the Court cannot find that the plaintiff’s “testi[mony] that she applied for
    disability when she began using oxygen, because that is what everyone told her she was
    supposed to do,” AR 21, suffices to warrant dismissing her allegations regarding her inability to
    stay awake. The ALJ made no effort to explain the significance of this statement to her analysis.
    And, it is not apparent to the Court how the plaintiff’s perception or misperception of when and
    under what circumstances it is appropriate to apply for disability benefits undermines her
    allegations regarding the specific symptoms she was experiencing. See 
    Butler, 535 F.3d at 1005
    (“The ALJ’s decision must contain specific reasons for the finding on credibility, supported by
    the evidence in the case record, and must be sufficiently specific to make clear to the individual
    30
    and to any subsequent reviewers the weight the adjudicator gave to the individual’s statements
    and reasons for that weight.” (internal quotation marks omitted)). Moreover, in any event,
    rejecting a plaintiff’s claim based on a single statement by her is inconsistent with the ALJ’s
    responsibility to “consider the entire case record” when “determining the credibility of the
    [claimant’s] statements.” SSR 96–7p, 
    1996 WL 374186
    , at *1. Thus, the ALJ’s reliance on the
    plaintiff’s statement regarding why she applied for disability benefits is insufficient to support
    her conclusion.
    The defendant’s counterarguments on this matter are also not persuasive. Contrary to the
    defendant’s position, the ALJ did not explicitly “note[] the sparse complaints of sleep apnea” in
    rejecting the plaintiff’s and Barnes’s statements regarding the plaintiff’s sleep apnea symptoms.
    Def.’s Resp. at 3. Moreover, although the defendant is correct that the ALJ noted a progress note
    from Nurse Worby representing that “[the] [p]laintiff [told Nurse Worby that she] could ‘sleep
    without difficulty’ at an August 2013 session,” 
    id. (quoting AR
    23, 618), the ALJ did so only in
    her initial summary of the available objective medical evidence, see AR 23, and did not offer this
    fact as a reason for her rejection of the plaintiff’s and Barnes’s statements regarding the
    plaintiff’s sleep apnea symptoms. Thus, the defendant’s arguments appear to be no more than
    “post hoc rationalizations” of the ALJ’s decision, which “will not suffice.” Clark v. Astrue, 
    826 F. Supp. 2d 13
    , 20 (D.D.C. 2011) (Walton, J.) (“[A] court may only consider the grounds
    proffered by the agency in its decision[.]”). 5 Furthermore, the ALJ’s finding that Nurse
    “Worby’s opinion about the frequency of [the] [p]laintiff’s ‘sleep attacks’ was inconsistent with
    the record,” Def.’s Resp. at 3, does not demonstrate that the plaintiff did not experience any sleep
    5
    In any event, it would be difficult to find that evidence suggesting that the plaintiff’s symptoms were controlled in
    one specific month could outweigh the plaintiff’s and Barnes’s statements regarding the persistence and severity of
    her symptoms.
    31
    attacks at all or any other sleep apnea symptoms. Thus, the defendant’s counterarguments do not
    persuade the Court that the ALJ adequately assessed the credibility of the plaintiff’s and Barnes’s
    statements regarding the plaintiff’s sleep apnea symptoms.
    Additionally, the Court cannot agree with the Magistrate Judge that “[t]he ALJ properly
    rejected [the] [p]laintiff’s claim of daytime ‘sleep attacks[]’ because her claim is not based on
    objective medical findings.” R & R at 11. First, the ALJ did not rely on the absence of objective
    medical evidence as the basis for rejecting the plaintiff’s allegations regarding the plaintiff’s
    sleep apnea symptoms, and, as already explained, the Court cannot rely on post hoc
    rationalizations not relied upon by the ALJ below. See 
    Clark, 826 F. Supp. 2d at 20
    . Second,
    even if the ALJ had relied on this observation, it would not suffice to support her conclusion
    because it is well established that an “ALJ may not reject [a] claimant’s statements solely
    because they are not substantiated by objective medical evidence; rather, [s]he ‘must consider the
    entire case record.’” Troy v. Colvin, 
    266 F. Supp. 3d 288
    , 296 (D.D.C. 2017) (quoting 
    Barnhart, 353 F.3d at 1005
    ); see SSR 96–7p, 
    1996 WL 374186
    , at *1 (“An individual’s statements about
    the intensity and persistence of pain or other symptoms or about the effect the symptoms have on
    his or her ability to work may not be disregarded solely because they are not substantiated by
    objective medical evidence.”). Therefore, the Magistrate Judge’s reasoning does not persuade
    the Court to find that the ALJ properly rejected the plaintiff’s evidence of sleep apnea symptoms
    either.
    Thus, although “[t]he credibility determination is solely within the realm of the ALJ,”
    Contreras v. Comm’r of Soc. Sec., 
    239 F. Supp. 3d 203
    , 210 (D.D.C. 2017) (quoting Grant v.
    Astrue, 
    857 F. Supp. 2d 146
    , 156 (D.D.C. 2012)), “[t]his does not[] [ ] give the ALJ unlimited
    discretion in making such a determination,” 
    id., and this
    Court must “intercede where an ALJ
    32
    fails to articulate a rational explanation for his or her finding,” 
    id. (quoting Grant
    , 
    857 F. Supp. 2d
    at 156). Here, for the reasons explained above, the ALJ failed to support her credibility
    findings with an adequate explanation and, thus, her credibility findings were error.
    Having concluded that the ALJ erred by discrediting the plaintiff’s and Barnes’s
    statements regarding the plaintiff’s sleep attacks and inability stay awake, the Court must
    consider whether the ALJ’s error was harmless, see, e.g., 
    Mitchell, 241 F. Supp. 3d at 166
    , which
    the Court finds it was not. Here, there exists evidence in the record that could support a finding
    that the plaintiff’s alleged inability to stay awake would preclude her from performing her past
    relevant work. Specifically, the impartial vocational expert testified at the plaintiff’s hearing that
    an “individual who is off task for [fifteen] to [eighteen] percent of [an eight-hour] workday . . .
    would not be able to maintain [any] position” in the national economy. AR 59. And, the
    plaintiff’s and Barnes’s statements that the plaintiff could not focus on a task for more than half
    an hour to an hour at a time and was often unable to stay awake, if credited by the ALJ upon
    remand, suggest that the plaintiff would be off task for more than the maximum allowable time
    of fifteen to eighteen percent—i.e., one hour and twelve minutes to one hour and twenty-six
    minutes—in an eight-hour workday. Thus, an ALJ could reasonably conclude based on this
    evidence that the plaintiff’s sleep attacks and inability to stay awake precluded her from
    performing her past relevant work. See Moe, 731 F. App’x at 592 (“The ALJ’s error in relying
    on several invalid reasons to discredit [the claimant’s] testimony was not harmless because it was
    not inconsequential to the nondisability determination.”); see also Porter v. Colvin, 
    951 F. Supp. 2d
    125, 136–37 (D.D.C. 2013) (“The ALJ characterizes the medical record in a way that makes
    [the] [p]laintiff's statements appear inconsistent, leading to an adverse credibility finding that
    directly influences her [residual functional capacity]. Because the totality of the record casts her
    33
    complaints in a very different light—indeed, as supported by the medical record—it could very
    well lead to a different result, and prejudice does potentially lie.”).
    Moreover, the Court is unable to locate any evidence in the record demonstrating that the
    plaintiff could perform her past relevant work despite the evidence regarding her inability to stay
    awake. Notably, the state agency consultants’ opinions did not explicitly address the plaintiff’s
    alleged inability to stay awake. See AR 73–75 (assessing the plaintiff’s exertional, postural, and
    environmental limitations but not reporting any mental limitations); AR 82–84 (same).
    Additionally, the plaintiff’s daily activities do not adequately support the ALJ’s conclusion that
    the plaintiff could perform her past relevant work, as “the ability to engage in activities such as
    cooking, cleaning, and hobbies, does not constitute substantial evidence of the ability to engage
    in substantial gainful activity.” Brosnahan v. Barnhart, 
    336 F.3d 671
    , 677 (8th Cir. 2003). This
    is especially so here, given that the ALJ “ignored the limited fashion [in which] the plaintiff
    engages in . . . [her] activities,” 
    Jackson, 271 F. Supp. 2d at 36
    , and also given that there exists
    little to no evidence that the plaintiff’s activities are “easily transferable to a work environment
    where it might be impossible to rest periodically,” 
    Smolen, 80 F.3d at 1284
    n.7 (9th Cir. 1996);
    see 
    Petty, 204 F. Supp. 3d at 207
    (“Many employers require a certain output level from their
    employees over a given amount of time, and an individual with deficiencies in [concentration,
    persistence, or] pace might be able to perform simple tasks, but not over an extended period of
    time.” (alterations in original) (quoting Ramirez v. Barnhart, 
    372 F.3d 546
    , 554 (3d Cir. 2004))).
    Finally, the plaintiff’s failures to follow her treatment protocol also do not support the ALJ’s
    conclusion because “[f]ailure to follow a prescribed treatment plan is a basis for denying a
    claimant benefits [only] when following the treatment plan would restore the claimant’s ability
    to work.” 
    Jackson, 271 F. Supp. 2d at 38
    (citing 20 C.F.R. § 404.1530); see 20 C.F.R.
    34
    § 404.1530 (“In order to get benefits, you must follow treatment prescribed by your medical
    doctor(s) if th[e] treatment is expected to restore your ability to work.” (emphasis added)). The
    ALJ did not make any findings regarding the extent to which the plaintiff’s treatment would
    alleviate her sleep apnea symptoms, and she ignored evidence that the plaintiff was unable to
    obtain the correct mask for her CPAP machine, see AR 607, and the plaintiff’s testimony that
    some of her treatment actually exacerbated her symptoms, see AR 45 (the plaintiff testifying that
    her diabetic neuropathy medicine “does[] [not] help the sleepiness because it makes [her] even
    more sleepy”). Thus, the Court cannot conclude that other evidence in the record clearly
    demonstrates that the plaintiff could perform her past relevant work notwithstanding her sleep
    apnea symptoms, such that the ALJ’s error in discrediting the plaintiff’s and Barnes’s statements
    regarding those symptoms was harmless. See Payne v. Barnhart, 
    725 F. Supp. 2d 113
    , 119
    (D.D.C. 2010) (reversing the ALJ’s decision because the ALJ “fail[ed] to address [the plaintiff’s]
    inability to concentrate and maintain attention for extended periods” and “the [c]ourt s[aw]
    nothing in the record to support the ALJ’s determination that, given [the plaintiff’s] inability to
    concentrate, he would be mentally capable of performing the duties of [his past relevant work as]
    a security guard”); cf. Barlow, 
    2018 WL 2410361
    , at *7–8 (concluding that the ALJ’s “fail[ure]
    to accurately capture all of [the] [p]laintiff’s visual limitations . . . was harmless” because the
    plaintiff “performed all of his past employment notwithstanding those limitations,” and thus, “the
    record ma[de] clear that [he] could perform his past jobs with his vision impairments”); 
    Davis, 272 F. Supp. 3d at 172
    (concluding that an ALJ’s “fail[ure] to include . . . [the] [p]laintiff’s mild
    limitation in concentration, persistence, or pace” in her residual functional capacity was harmless
    because “the ALJ identified substantial medical and other evidence of record—including [the
    plaintiff’s] completion of cosmetology school and high school and the opinions of . . . [three
    35
    physicians]—establishing that [the] [p]laintiff [wa]s capable of performing ‘simple, routine, and
    repetitive tasks’”).
    In sum, the Court concludes that the ALJ erred by failing to provide adequate reasons for
    her decision to discred the plaintiff’s and Barnes’s statements regarding the plaintiff’s sleep
    apnea symptoms. Additionally, the Court concludes that the ALJ’s error was not harmless.
    Accordingly, the Court must remand this case to the ALJ for reconsideration of the plaintiff’s
    and Barnes’s statements regarding the plaintiff’s sleep apnea symptoms.
    C.      The ALJ’s Reliance on the State Agency Consultants’ Opinions
    The plaintiff’s final argument is that the ALJ’s reliance on the state agency consultants’
    opinions constituted error for three reasons: (1) the opinions were rendered by “non-examining”
    physicians and “not based on a description of [the] [p]laintiff’s limitations by any examining
    physician,” Pl.’s Objs. at 8; (2) the opinions were “stale” because the consultants “had only a
    small fraction of [the plaintiff’s pre-June 2012] records to [ ] review,” 
    id. at 4
    ; and (3) “the ALJ’s
    boilerplate statement that the [ ] opinions were consistent with the record[]” is “insufficient for
    purposes of judicial review,” 
    id. at 6,
    given that the opinions were “inconsistent with the only
    other [medical] opinion of record,” i.e., Nurse Worby’s opinion, 
    id. at 8.
    The defendant responds
    that “[t]he ALJ’s reliance on the opinion of state [agency] medical consultants was proper” and
    that “[t]he ALJ thoroughly reviewed and discussed the relevant evidence, including evidence that
    was submitted after the state agency medical opinions.” Def.’s Resp. at 2.
    First, the Court must reject the plaintiff’s position that the ALJ’s reliance on the state
    agency consultants’ opinions was improper because the opinions were rendered by non-
    examining physicians or because the consultants “w[ere] not provided a description of [the]
    [claimant’s] limitations by examining physicians.” Pl.’s Objs. at 6. The plaintiff cites no
    36
    authority as support for the proposition that an ALJ may not rely on the opinion of a non-
    examining physician, and the regulations expressly contemplate the ALJ’s reliance on opinions
    provided by nonexamining state agency medical consultants. See 20 C.F.R. § 404.1513(c)
    (contemplating that an ALJ may consult residual functional capacity assessments “made by . . .
    State agency medical . . . consultants . . . based on their review of the evidence in the case
    record”); 
    id. § 1527(c)(3)
    (providing instructions for the evaluation of opinions from
    “nonexamining sources”). Moreover, the plaintiff also fails to cite any authority for the position
    that a non-examining physician must receive a description of the plaintiff’s limitations from
    examining physicians. The case cited by the plaintiff as support for her position, Grant v.
    Astrue, see Pl.’s Objs. at 6, only acknowledges the Fourth Circuit’s conclusion in Smith v.
    Schweiker that “the medical opinions of non-examining physicians who were not provided a
    description of a claimant’s limitations by an examining medical source, and whose opinions are
    contradicted by all of the other evidence in the record, could not be given substantial weight,”
    Grant, 
    857 F. Supp. 2d
    at 155 (emphasis added) (citing Smith v. Schweiker, 
    795 F.2d 343
    , 348
    (4th Cir. 1986)). The plaintiff does not claim that the state agency consultants’ opinions were
    “contradicted by all of the other evidence in the record,” 
    id., but only
    that they were contradicted
    by Nurse Worby’s opinion, see Pl.’s Objs. at 8. Moreover, in Smith, the Fourth Circuit based its
    conclusion on the specific circumstances of that case, including the fact that “an opinion or
    diagnosis as to [the] impairment [at issue] . . . [wa]s not readily made without the physician
    personally examining or observing the patient,” 
    Smith, 795 F.2d at 346
    . Here, the plaintiff has
    made no effort to demonstrate why the state agency consultants could not properly assess her
    specific impairments without examining her. In any event, the state agency consultants received
    at least some progress notes from Nurse Worby, see, e.g., AR 71, who examined the plaintiff,
    37
    and thus, these consultants were to some extent “provided a description of [the] claimant’s
    limitations by an examining medical source,” Grant, 
    857 F. Supp. 2d
    at 155. Thus, the Court
    must reject the plaintiff’s argument that the state agency consultants’ opinions were invalid
    simply because the consultants did not examine the plaintiff or review all of Nurse Worby’s
    records.
    Second, the Court must reject the plaintiff’s position that the ALJ’s reliance on the state
    agency consultants’ opinions was improper because the opinions were “stale.” Although the
    plaintiff appears to correctly represent that the state agency consultants did not consider the post-
    June 2012 evidence, see AR 71–72 (indicating that Dr. Nicholas considered only Nurse Worby’s
    treatment records received by the SSA prior to August 14, 2012); AR 79–80 (indicating that Dr.
    McMorris considered only Nurse Worby’s treatment records received by the SSA prior to
    August 14, 2012, and Washington Hospital Center records received on August 21, 2012, and
    December 7, 2012); AR 578–650 (Nurse Worby’s progress notes dated June 4, 2012, to April 17,
    2014), “[n]ew medical evidence introduced into the record after a [s]tate agency consultant’s
    assessment does not automatically render that assessment invalid,” Goodman v. Colvin, 233 F.
    Supp. 3d 88, 105 (D.D.C. 2017).
    However, the Court must agree with the plaintiff that the ALJ did not adequately explain
    her reliance on the state agency consultants’ opinions given the existence of evidence in the
    record contradicting those opinions, including post-June 2012 evidence. As already explained,
    the ALJ gave “great weight” to the state agency consultants’ opinions because they were
    “consistent” with record evidence reflecting the plaintiff’s “level of functioning” and “with the
    evidence at the hearing level.” AR 23. However, the consultants’ conclusions that the plaintiff
    could sit with normal breaks for a total of six hours in an eight-hour workday, see, e.g., AR 74,
    38
    are inconsistent with the plaintiff’s and Barnes’s statements that the plaintiff was “unable to stay
    awake for long periods of time,” AR 199, as well as information contained in the post-June 2012
    evidence supporting those statements, see, e.g., AR 607 (noting that the plaintiff reported
    “nodding off during conversations”). Because the ALJ improperly rejected the plaintiff’s and
    Barnes’s statements and did not explicitly address other evidence in the record that is
    inconsistent with the state agency consultants’ opinions, the Court must conclude that the ALJ
    inadequately explained her reliance on the state agency consultants’ opinions. See Charles v.
    Astrue, 
    854 F. Supp. 2d 22
    , 29 (D.D.C. 2012) (Walton, J.) (“The adjudicator must [ ] explain
    how any material inconsistencies or ambiguities in the evidence in the case record were
    considered and resolved.”).
    Moreover, the Court cannot find that the ALJ’s failure to adequately explain her reliance
    on the state agency consultants’ opinions constitutes harmless error, as the error frustrates the
    ability of the Court to conduct meaningful review and determine whether the ALJ’s decision is
    supported by substantial evidence.” Carroll v. Berryhill, Civ. Action No. 16 -218, 
    2018 WL 1913587
    , at *3 (W.D.N.C. Apr. 23, 2018) (concluding that an “ALJ’s failure to provide a
    sufficient explanation [wa]s not harmless error”); see 
    Turner, 710 F. Supp. 2d at 105
    (“A
    reviewing court should not be left guessing as to how the ALJ evaluated probative material, and
    it is reversible error for an ALJ to fail in his written decision to explain sufficiently the weight he
    has given to certain probative items of evidence.”). Thus, the ALJ’s failure to adequately explain
    her reliance on the state agency consultants’ opinions represents an additional reason for the
    Court to reverse the ALJ’s decision in this case.
    39
    IV.      CONCLUSION
    For the foregoing reasons, the Court concludes that the ALJ committed reversible error
    by discrediting the plaintiff’s and Barnes’s statements regarding the plaintiff’s inability to stay
    awake and by failing to adequately address and resolve inconsistencies between the state agency
    consultants’ opinions and other evidence in the record. However, the Court rejects the plaintiff’s
    remaining challenges to the ALJ’s decision. Thus, the Court concludes that it must grant in part
    and deny in part the plaintiff’s motion for a judgment of reversal, deny the defendant’s motion
    for judgment of affirmance, and remand this case to the Commissioner for further proceedings
    consistent with this Memorandum Opinion. 6
