    2022-NCSC-95
    Opinion of the Court
    MORGAN, Justice.
    ¶1         Plaintiffs petitioned this Court for discretionary review of the unanimous
    opinion rendered by the Court of Appeals in Connette ex rel. Gullatte v. Charlotte-
    Mecklenburg Hospital Authority, 
    272 N.C. App. 1
     (2020), in which the lower appellate
    court found no error in the trial court’s exclusion of evidence proffered by plaintiffs at
    trial in an effort to show that defendant VanSoestbergen breached the professional
    duty of care which governed his participation in the preparation and administration
    of a course of anesthesia which resulted in profound injuries being suffered by
    plaintiff Amaya Gullatte. The trial court’s evidentiary ruling, and the Court of
    Appeals’ affirmance of it, was dictated by the application of the principle entrenched
    by Byrd v. Marion General Hospital, 
    202 N.C. 337
     (1932) and its progeny which
    categorically establishes that nurses do not owe a duty of care in the diagnosis and
    treatment of patients while working under the supervision of a physician licensed to
    practice medicine in North Carolina. 
    Id.
     at 341–43. Due to the evolution of the
    medical profession’s recognition of the increased specialization and independence of
    nurses in the treatment of patients over the course of the ensuing ninety years since
    this Court’s issuance of the Byrd opinion, we determine that it is timely and
    appropriate to overrule Byrd as it is applied to the facts of this case. Accordingly, we
    reverse and remand this matter to the trial court for further proceedings consistent
    with this opinion.
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    I.   Factual and Procedural Background
    ¶2         On 11 September 2010, an emergency room visit for an upper respiratory
    infection revealed that three-year-old Amaya Gullatte was tachycardic, prompting
    Amaya’s pediatrician to refer the child to a cardiologist. The cardiologist’s
    examination of Amaya disclosed that the youngster was plagued by the heart disease
    known as cardiomyopathy, an affliction which enlarges the heart and makes it
    difficult for the heart to pump blood correctly. The cardiologist recommended the
    performance of an “ablation procedure” on Amaya’s heart in order to address the
    disorder. The child was admitted to a Carolinas Medical Center facility on 20 October
    2010, where an anesthetics team consisting of anesthesiologist James M. Doyle, M.D.
    and Certified Registered Nurse Anesthetist (CRNA) Gus C. VanSoestbergen utilized
    a mask to administer the anesthetic sevoflurane to Amaya prior to the surgical
    procedure. Shortly after she was induced with the sevoflurane, Amaya went into
    cardiac arrest. Although the introduction of resuscitation drugs and the performance
    of cardiopulmonary resuscitation (CPR) by Dr. Doyle was able to revive Amaya, still
    the approximately thirteen minutes of oxygen deprivation which was experienced by
    the child resulted in the onset of permanent brain damage, cerebral palsy, and
    profound developmental delay. Plaintiff Edward Connette, as Amaya’s guardian ad
    litem, and plaintiff Andrea Hopper, as Amaya’s mother, filed a lawsuit against Dr.
    Doyle, CRNA VanSoestbergen, the Charlotte-Mecklenburg Hospital Authority, and
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    two additional physicians who treated Amaya.
    ¶3           The trial spanned three months and concluded in February 2016. While the
    jury returned a verdict in favor of the two additional treating physicians, the jury
    failed to reach a verdict on the claims against Dr. Doyle and CRNA VanSoestbergen.
    Dr. Doyle and his anesthesiology practice proceeded to settle plaintiffs’ claims against
    them.
    ¶4           A second trial commenced in May 2018, in which plaintiffs asserted a number
    of claims based on negligence against CRNA VanSoestbergen and the hospital as
    VanSoestbergen’s employer. In plaintiffs’ opening statement during the second trial,
    their counsel referenced a leading pharmacology textbook’s description of a process
    known as intravenous introduction of etomidate, which was depicted as a safer
    alternative to the method of introducing sevoflurane through the usage of a mask into
    a patient who has cardiomyopathy. Witnesses testified that Dr. Doyle, in his capacity
    as the anesthesiologist for the procedure, and CRNA VanSoestbergen, in his
    respective role as the nurse anesthetist for the surgery, collaborated on Amaya’s plan
    as both medical professionals independently and identically determined that
    sevoflurane mask induction was the appropriate course of action to implement. CRNA
    VanSoestbergen concurred with Dr. Doyle’s final decision to order this method of the
    introduction of the anesthetic into Amaya’s system after the two consulted with one
    another about the plan. While the ultimate decision to order the chosen
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    anesthesiological procedure rested with the physician Dr. Doyle, the certified
    registered nurse anesthetist VanSoestbergen advised the physician, agreed with the
    physician, and participated with the physician in the election and administration of
    the anesthetic sevoflurane through a mask.
    ¶5         Plaintiffs were prepared to present evidence through certified registered nurse
    anesthetist Dean Cary acting as an expert witness on the manner in which CRNA
    VanSoestbergen’s formulation of, affirmation of, and contribution to the decision to
    administer sevoflurane to Amaya by utilizing the mask induction procedure rather
    than by utilizing an intravenous method to induce anesthesia, allegedly breached the
    professional standard of care applicable to VanSoestbergen. However, the trial court
    determined that the introduction of evidence regarding a professional standard of
    care which should apply to VanSoestbergen in his capacity as a certified registered
    nurse anesthetist was precluded by Daniels v. Durham County Hospital Corp., 
    171 N.C. App. 535
     (2005), disc. rev. denied, 
    360 N.C. 289
     (2006), a case which directly
    applied this Court’s holding in Byrd to govern the outcome in Daniels and which the
    trial court, in turn, directly applied to the present case. Specifically, the trial court
    prohibited the introduction of testimony from plaintiffs’ expert witness Cary which
    would have tended to show that the standard practice of CRNAs under the medical
    facts of Amaya’s case would have expressly prohibited the course of action followed
    by CRNA VanSoestbergen. If allowed by the trial court to do so, the expert would
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    have testified that an intravenous introduction of a drug other than sevoflurane, such
    as etomidate, would have complied with the applicable professional standard of care
    for a certified registered nurse anesthetist like VanSoestbergen, while the use of
    sevoflurane mask induction in this instance would breach the applicable professional
    standard of care. In its ruling which excluded this aspect of evidence from the
    testimony rendered by the expert witness Cary, the trial court observed that a nurse
    may be liable for independent actions taken against a plaintiff but could not be held
    liable for planning and selecting the appropriate anesthesia technique because
    nurses operate under the compulsory supervision of physicians licensed to practice
    medicine.
    ¶6         On 17 July 2018, pursuant to North Carolina General Statutes Section 1A-1,
    Rule 48, the parties stipulated on the record to the validity of a trial verdict rendered
    by nine or more jurors. The jury returned a verdict in favor of VanSoestbergen and,
    correspondingly, his hospital employer, and the trial court entered judgment
    memorializing the jury’s verdict on 20 August 2018. Plaintiffs appealed, among other
    matters, the trial court’s exclusion of plaintiffs’ proffered expert testimony regarding
    CRNA VanSoestbergen’s involvement in the determination and implementation of
    the allegedly negligent anesthesia plan as a claimed breach of the applicable
    professional standard of care. On 16 June 2020, the Court of Appeals affirmed the
    trial court’s exclusion of the evidence at issue in a unanimous decision. Connette, 272
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    N.C. App. at 5, 13. Plaintiffs filed a Petition for Discretionary Review of the lower
    appellate court’s determination, and this Court allowed the petition on 10 March
    2021.
    II.     Analysis
    ¶7           A trial court’s determination as to the admissibility of evidence, particularly
    when such admissibility is called into question on the issue of relevance, is generally
    reviewed for abuse of discretion. See, e.g., State v. Williams, 
    363 N.C. 689
    , 701–02
    (2009), cert. denied 
    562 U.S. 864
     (2010); State v. Jacobs, 
    363 N.C. 815
    , 823 (2010).
    The trial court’s exclusion of plaintiffs’ proffered testimony in the case sub judice was
    governed by the application of Daniels v. Durham County Hospital Corp.,
    171 N.C. App. at 538–40, in which the Court of Appeals properly implemented the
    unequivocal holding in Byrd that nurses did not owe an independent duty to patients
    in the selection and planning of treatment. The existence of a duty of care between a
    defendant and a plaintiff is a question of law. See Pinnix v. Toomey, 
    242 N.C. 358
    ,
    362 (1955); see generally Fussell v. N.C. Farm Bureau Mut. Ins. Co., 
    364 N.C. 222
    ,
    225–26 (2010) (reciting elements of negligence, including duty of care). “We review
    questions of law de novo.” State v. Graham, 
    379 N.C. 75
    , 2021-NCSC-125, ¶ 7 (quoting
    State v. Khan, 
    366 N.C. 448
    , 453 (2013)). A trial court’s determination of the
    admissibility of evidence which depends dispositively upon its conclusion regarding a
    question of law is likewise reviewed de novo. See e.g., Da Silva v. WakeMed, 375 N.C.
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    1, 4–5 (2020).
    A. Substantive Law
    ¶8         Medical malpractice actions in North Carolina are negligence claims upon
    which the Legislature has seen fit to erect extra statutory requirements—both
    substantive and procedural—which a plaintiff must satisfy in order to sustain such
    allegations. Turner v. Duke Univ., 
    325 N.C. 152
    , 162 (1989) (explaining that medical
    malpractice actions require a plaintiff to offer competent evidence of “(1) the standard
    of care, (2) breach of the standard of care, (3) proximate causation, and (4) damages”);
    see N.C.G.S. § 1A-1, Rule 9(j) (2021) (requiring dismissal of medical malpractice
    complaints which do not include one of three enumerated averments). Medical
    malpractice actions are prescribed by a specific set of enactments found in Article 1B
    of Chapter 90 of the North Carolina General Statutes. N.C.G.S. §§ 90-21.11 to -21.19B
    (2021). A medical malpractice action is defined as a “civil action for damages for
    personal injury or death arising out of the furnishing or failure to furnish professional
    services in the performance of medical, dental, or other health care by a health care
    provider.” Id. § 90-21.11(2)(a). The statute expressly contemplates medical
    malpractice actions against registered nurses for professional services rendered in
    the performance of “medicine,” “nursing,” providing “assistance to a physician,” and
    other types of health care listed therein. Id. § 90-21.11(1)(a). In order to sustain a
    medical malpractice action, it is a plaintiff’s burden to establish by the greater weight
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    of the evidence that a defending party breached its duty of care by exhibiting
    professional conduct which was “not in accordance with the standards of practice
    among members of the same health care profession with similar training and
    experience situated in the same or similar communities under the same or similar
    circumstances at the time of the alleged act giving rise to the cause of action.” Id. §
    90-21.12(a). Therefore, these statutes collectively create the requirement of
    registered nurses to act in accordance with applicable and appropriate standards of
    practice and establish the burden of proof which a plaintiff must satisfy in order to
    demonstrate that a registered nurse has violated the expected applicable professional
    standard of care.
    ¶9         Upon this Court’s issuance of the Byrd decision in 1932, nurses have not been
    subject to culpability for the performance of their roles in the administration of any
    negligent treatment of a patient and could only be held liable for the execution of
    their primary function within the medical community, which was to “obey and
    diligently execute the orders of the physician or surgeon in charge of the patient,
    unless, of course, such order was so obviously negligent as to lead any reasonable
    person to anticipate that substantial injury would result.” Byrd, 
    202 N.C. at 341
    .
    While a nurse could be held liable for how nursing duties were executed outside the
    supervision of a physician, it was clear from Byrd that a nurse could not be held liable
    for what the nurse did to “diligently execute the orders of the physician.” 
    Id.
     at 341–
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    43. In Byrd, this Court was asked to answer the legal question: “What duty does a
    nurse owe to a patient?” 
    Id. at 341
    . In responding to this query, we reasoned that
    “[n]urses are not supposed to be experts in the technique of diagnosis or the
    mechanics of treatment”; instead, “the law contemplates that the physician is solely
    responsible for the diagnosis and treatment of his patient.” 
    Id.
     at 341–42. Thus, a
    nurse could only be held liable for the negligent treatment of a patient when (1) the
    nurse acted without direction from and outside the presence of a physician, and thus
    without the requisite “acquiescence and implied approval of the physician,” or (2) the
    nurse was undertaking to carry out a physician’s order that “was so obviously
    negligent as to lead any reasonable person to anticipate that substantial injury would
    result.” 
    Id. at 343, 341
    . As a result, nurses were largely exempted from the existence
    of any applicable professional standard of care, because nurses were deemed by Byrd
    to be sheltered from exposure to liability for negligence when performing duties under
    the supervision of a physician and were only vulnerable to negligence claims due to
    the performance of their professional duties and responsibilities when substandard
    execution of such nursing expectations was obvious.
    ¶ 10         North Carolina was the first state in the nation to regulate the registration of
    practicing nurses with the creation of The Board of Examiners of Trained Nurses of
    North Carolina in 1903. Act of Mar. 3, 1903, ch. 359, 1903 N.C. Pub. Laws 58b
    (captioned An Act to Provide for the Registration of Trained Nurses). By the time that
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    Byrd was decided almost thirty years later, the regulation of nursing was still
    confined to the examination and licensure of applicants who wished to use the title
    “trained,” “graduate,” “licensed,” or “registered” nurse. N.C. Code Ann. §§ 6729, 6734,
    6738 (Michie 1935). Licensure did not become a prerequisite to practice nursing
    generally until 1965. Act of May 18, 1965, ch. 578, § 1, 1965 N.C. Sess. Laws (Reg.
    Sess. 1965) 624, 624 (captioned An Act to Rewrite and Consolidate Articles 9 and 9A
    of Chapter 90 of the General Statutes with Respect to the Practice of Nursing). In
    1932, applicants for registration with the Board, which had been renamed The Board
    of Nurse Examiners of North Carolina, were required to be at least twenty-one years
    of age, of good moral character, a high school graduate, and either a graduate of a
    school of nursing or one who had practiced nursing in another state under similar
    registration requirements. N.C. Code Ann. §§ 6731, 6733 (Michie 1935). The Board of
    Nurse Examiners was empowered with the authority to conduct periodic
    examinations “in anatomy and physiology, materia medicia, dietetics, hygiene, and
    elementary bacteriology, obstetrical, medical and surgical nursing, nursing of
    children, contagious diseases and ethics in nursing, and such other subjects as may
    be prescribed by the examining board.” Id. § 6732. The examination fee totaled ten
    dollars, id., and the Board possessed the power to revoke a registered nurse’s license
    for cause pursuant to notice and hearing requirements, id. § 6737. Despite the
    sweeping authority which was vested in the North Carolina Board of Nurse
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    Examiners as the importance and influence of nurses within the field of medicine
    grew, nonetheless the express and specific identification of a nurse’s role of legal
    responsibility within the medical industry remained undefined by any statutory
    enactment of the Legislature. Consequently, by way of the Byrd decision, this Court
    filled this legal culpability vacuum with the pronouncement that a nurse could only
    “be held liable in damages for any failure to exercise ordinary care” when working
    outside of the immediate supervision of a physician or when the treatment ordered
    by the physician was “obviously negligent or dangerous.” Byrd, 
    202 N.C. at 343
    .
    ¶ 11         The nursing profession has evolved tremendously over the ninety years since
    Byrd. Since 1965, all persons practicing as nurses in North Carolina must be licensed
    by the North Carolina Board of Nursing (the Nursing Board) as either a “registered
    nurse” or “licensed practical nurse.” Ch. 578, § 1, 1965 N.C. Sess. Laws at 625, 628–
    29; N.C.G.S. § 90-171.43 (2021). The Nursing Board is empowered to adopt, amend,
    repeal, and interpret rules pursuant to North Carolina’s Nursing Practice Act, a
    comprehensive enactment regulating the nursing profession found in Chapter 90,
    Article 9A of the North Carolina General Statutes. See N.C.G.S. § 90-171.23(b) (2021)
    (listing the Board’s duties and powers).
    ¶ 12         With particular regard to registered nurses in the state, the Legislature has
    defined the “practice of nursing by a registered nurse” as having ten components:
    a. Assessing the patient's physical and mental health,
    including the patient's reaction to illnesses and treatment
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    regimens.
    b. Recording and reporting the results of the nursing
    assessment.
    c. Planning,    initiating,  delivering,       and   evaluating
    appropriate nursing acts.
    d. Teaching, assigning, delegating to or supervising other
    personnel in implementing the treatment regimen.
    e. Collaborating with other health care providers in
    determining the appropriate health care for a patient but,
    subject to the provisions of G.S. 90-18.2, not prescribing a
    medical treatment regimen or making a medical diagnosis,
    except under supervision of a licensed physician.
    f. Implementing the treatment and pharmaceutical regimen
    prescribed by any person authorized by State law to
    prescribe the regimen.
    g. Providing teaching and counseling about the patient’s
    health.
    h. Reporting and recording the plan for care, nursing care
    given, and the patient’s response to that care.
    i. Supervising, teaching, and evaluating those who perform
    or are preparing to perform nursing functions and
    administering nursing programs and nursing services.
    j. Providing for the maintenance of safe and effective nursing
    care, whether rendered directly or indirectly.
    Id. § 90-171.20(7) (2021) (emphases added).
    ¶ 13         The Nursing Board has further refined the scope of nursing practice. The
    profession’s practice has evolved to include (1) the assessment of nursing care needs
    resulting in the “[f]ormulation of a nursing diagnosis,” (2) developing care plans
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    which include the determination and prioritization of nursing interventions, and (3)
    implementing nursing activities. Components of Nursing Practice for the Registered
    Nurse, 
    21 N.C. Admin. Code 36
    .0224 (2021). When a registered nurse “assumes
    responsibility directly or through delegation for implementing a treatment or
    pharmaceutical regimen,” the nurse becomes accountable for “anticipating those
    effects that may rapidly endanger a client’s life or well-being.” License Required, 
    id. 36
    .0221(c)(7) (2021). Lastly, the Nursing Board also oversees the additional licensure
    of certain types of registered nurses for specialized roles; namely, Certified Registered
    Nurse Anesthetist, Certified Nurse Midwife, Clinical Nurse Specialist, and Nurse
    Practitioner. These categories of advanced practice registered nurses must all obtain
    additional education and certifications to practice in their respective recognized,
    specific, and unique specialties. N.C. Bd. of Nursing, APRN Requirements At-A-

    ¶ 14         Pursuant to the statutory grant of rulemaking power afforded to it in N.C.G.S.
    § 90-171.23(b), the Nursing Board has defined the practice of a certified registered
    nurse anesthetist as the performance of “nurse anesthesia activities in collaboration
    with a physician, dentist, podiatrist, or other lawfully qualified health care provider.”
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.

    Opinion of the Court
    Nurse Anesthesia Practice, 
    21 N.C. Admin. Code 36
    .0226(a) (emphasis added). The
    rules further expound upon this collaboration as
    a process by which the certified registered nurse
    anesthetist works with one or more qualified health care
    providers, each contributing his or her respective area of
    expertise consistent with the appropriate occupational
    licensure laws of the State and according to the established
    policies, procedures, practices, and channels of
    communication that lend support to nurse anesthesia
    services and that define the roles and responsibilities of the
    qualified nurse anesthetist within the practice setting.
    
    Id. 36
    .0226(b). Such collaboration between a physician and a registered nurse such
    as a CRNA is contemplated to include “participating in decision-making and in
    cooperative goal-directed efforts.” Components of Nursing Practice for the Registered
    Nurse, 
    id. 36
    .0224(g)(2). Depending on “the individual’s knowledge, skills, and other
    variables in each practice setting,” CRNAs are expressly allowed to (1) select and
    administer preanesthetic medications, (2) select, implement, and manage general
    anesthesia consistent with the patient’s needs and procedural requirements, and (3)
    initiate and administer several palliative and emergency medical procedures.

    .0226(c)–(d). It is clear that CRNAs must fulfill these duties under the supervision
    of a licensed physician. N.C.G.S. § 90-171.20(7)(e). But, it is also apparent that the
    independent status, the professional stature, the individual medical determinations,
    and the shared responsibilities with a supervising physician have grown in
    significance and in official recognition since Byrd for a nurse such as a certified

    Opinion of the Court
    registered nurse anesthetist.
    B. Historical Application
    ¶ 15         Amidst this growing authority and influence which have been wielded by
    members of the nursing profession during the span of ninety years since this Court
    issued the Byrd decision, the state’s appellate courts have applied Byrd with
    increasing strain. In Blanton v. Moses H. Cone Memorial Hospital, Inc., this Court
    did not apply Byrd as a bar to a plaintiff’s claims against a nurse, but utilized Byrd
    to reiterate that a plaintiff’s claim against a nurse is valid “if the plaintiff can prove
    an agent of the hospital followed some order of the doctor which” was “so obviously
    negligent as to lead any reasonable person to anticipate that substantial injury would
    result to the patient by the execution of such order.” 
    319 N.C. 372
    , 376 (1987) (quoting
    Byrd, 
    202 N.C. at 341
    ).
    ¶ 16         Several years after Blanton, this Court was presented with “the opportunity to
    test the liability of a surgeon for the negligence of operating room personnel under
    the borrowed servant rule.” Harris v. Miller, 
    335 N.C. 379
    , 388 (1994). In Harris, the
    plaintiff sued an orthopedic surgeon for medical malpractice under a theory of
    vicarious liability, alleging that the physician was responsible pursuant to the
    doctrine of respondeat superior for a CRNA’s negligent administration of anesthesia
    while the nurse was under the physician’s direct supervision during a surgical
    procedure. Id. at 383. The trial court entered a directed verdict in favor of the
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    physician after finding that the plaintiff had failed to establish a master-servant
    relationship between the independent physician and the CRNA who was employed
    by the hospital where the physician performed the surgery. The Court of Appeals
    affirmed the trial court’s decision. Although this Court “held that the Court of
    Appeals erred in affirming the trial court’s directed verdict for Dr. Miller on plaintiff’s
    vicarious liability claim” and “reverse[d] and remand[ed] for a new trial on this
    claim,” id. at 400, nonetheless, this Court, in its decision in Harris, offered
    observations which were not expressly focused on Byrd but still served to dilute the
    efficacy of the foundation which has undergirded Byrd. In examining the relevant
    case law concerning the existence of employer-employee relationships in the context
    of supervising surgeons and the operating room personnel who participate in a
    surgical procedure, this Court identified the pivotal nature of the application of the
    Byrd approach in the resolution of Harris. The seminal case on the issue presented
    in Harris—Jackson v. Joyner, 
    236 N.C. 259
     (1952)1—had given rise to a judicially
    created “presumption that the surgeon in charge controls all operating room
    personnel,” which would inure to the benefit of the plaintiff in Harris by establishing
    a per se determination of liability on the part of the physician for the negligence of
    the nurse under the physician’s supervision. 335 N.C. at 388–89. While the Court
    reasoned that the presumption “may have been appropriate in an era in which
    1   Jackson has been effectively overruled by Harris. See Harris, 335 N.C. at 391.
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    hospitals undertook only to furnish room, food, facilities for operation, and
    attendance” and “in which only physicians had the expertise to make treatment
    decisions,” the Court concluded that such a presumption “is no longer appropriate in
    this era.” Id. at 389 (extraneity omitted) (citing Byrd, 
    202 N.C. at
    341–42, for the
    proposition concerning the exclusive expertise of physicians making treatment
    decisions). The Harris Court in 1994 noted that since the issuance of Jackson in 1952,
    hospitals had transformed into treatment centers and now exercised “significant
    control over the manner in which their employees, including staff physicians, provide
    treatment.” 
    Id. at 390
    . With this acknowledgment, the Court opined that “it is no
    longer appropriate” to presume that a hospital which has hired its own employees,
    such as nurses, cedes control over them to a supervising physician under a traditional
    “borrowed employee” analysis simply because the hospital had assigned the nurse to
    be directly supervised by an independent surgeon. 
    Id.
     at 389–90. While Jackson
    derived its presumption “from the mere fact that [the defendant] was the ‘surgeon in
    charge,’ ” this paradigm of the physician fully controlling a supervised nurse and all
    other medical personnel involved in a surgical procedure, resulting in the physician’s
    ultimate responsibility for each medical contributor’s actions in conjunction with the
    surgery, “no longer reflects . . . . [p]resent[-]day hospitals.” 
    Id. at 389
     (quoting Rabon
    v. Rowan Mem’l Hospital, Inc., 
    269 N.C. 1
    , 11 (1967)). The Court stressed this medical
    field evolution with the further recognition in Harris, which we find particularly
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    relevant in the instant case which we now decide twenty-eight years later:
    [S]urgeons are no longer the only experts in the operating
    room. The operating team now includes nurses,
    technicians,      interns,      residents,      anesthetists,
    anesthesiologists and other specialized physicians. All of
    these are experts in their own fields, having received
    extensive training both in school and at the hospital. When
    directed to perform their duties, they do so without further
    instruction from the surgeon, relying instead on their own
    expertise regarding the manner in which those duties are
    performed. Some of them, like anesthesiologists and
    technicians, may have expertise not possessed by the
    surgeon. Thus, the surgeon will in some cases be ill-
    equipped, if not incapable, of controlling the manner in
    which assisting personnel perform their duties.
    
    Id.
     at 390–91 (emphases added) (citations omitted).
    ¶ 17         Although the Court made these observations in Harris concerning the
    antiquated view of the total subservience of a nurse and other members of a medical
    team to a supervising physician, nonetheless, the Court’s resolution of the vicarious
    liability claims in Harris based upon the specific analysis of the tort’s elements
    regarding the doctrine of respondeat superior and the accompanying “borrowed
    servant” doctrine allowed Byrd to retain its precedential status on the distinguishable
    legal issue of a nurse’s inability to be held liable on a theory of negligence for acts
    performed under the supervision of a physician. With Byrd remaining intact as
    controlling authority on this issue, the Court of Appeals followed this case precedent
    in determining Daniels in 2005. In Daniels, the plaintiffs brought legal action against
    the defendant hospital upon the death of their baby who died seven months after
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    suffering injuries which the plaintiffs alleged were sustained during their daughter’s
    delivery at the hospital. 171 N.C. App. at 536–37. In their lawsuit against the hospital
    and the mother’s private physician who performed the baby’s delivery, as well as
    other individuals that included two of the hospital’s nurses who were involved in the
    delivery, the plaintiffs alleged that the defendants were jointly and severally liable
    on the bases of negligence and medical malpractice for the baby’s injuries and
    subsequent death. Id. at 537. In affirming the trial court’s entry of summary
    judgment for the hospital on the plaintiffs’ claim that the delivery nurses failed to
    oppose the doctor’s decision to perform the delivery as the physician directed, the
    Court of Appeals stated:
    [P]laintiffs’ evidence is not sufficient to meet the standard
    set forth in Byrd v. Marion Gen. Hosp.
    Under Byrd, a nurse may not be held liable for
    obeying a doctor’s order unless such order was so obviously
    negligent as to lead any reasonable person to anticipate
    that substantial injury would result to the patient from the
    execution of such order or performance of such direction.
    The Court stressed that the law contemplates that the
    physician is solely responsible for the diagnosis and
    treatment of his patient. Nurses are not supposed to be
    experts in the technique of diagnosis or the mechanics of
    treatment.
    Although these principles were set out more than 70
    years ago, they remain the controlling law in North
    Carolina. Plaintiffs refer repeatedly to the responsibilities
    of the “delivery team” and argue for a collaborative process
    with joint responsibility. While medical practices,
    standards, and expectations have certainly changed since
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    1932 [when the Supreme Court of North Carolina decided
    Byrd] and even since 1987 [when the Supreme Court of
    North Carolina decided Blanton], this Court is not free to
    alter the standard set forth in Byrd and Blanton.
    Id. at 538–39 (extraneity omitted).
    ¶ 18         Just as it did in its opinion in Daniels, the Court of Appeals in the present case
    likewise recognized that it was bound by the governing, albeit obsolescent, approach
    articulated in Byrd regarding a nurse’s blanket lack of exposure to liability for
    negligence when acting under the direction of a supervising physician. In its issued
    opinion in this matter, the lower appellate court assessed plaintiffs’ claim “that
    VanSoestbergen breached the applicable standard of care by agreeing, during the
    anesthesia planning stage, to induce Amaya with sevoflurane using the mask
    induction procedure.” Connette, 272 N.C. App. at 4. The Court of Appeals went on to
    further detail the specific contentions of plaintiffs:
    Plaintiffs asserted that certified registered nurse
    anesthetists are highly trained and have greater skills and
    treatment discretion than regular nurses. Moreover, they
    asserted, nurse anesthetists often use those skills to
    operate outside the supervision of an anesthesiologist.
    Plaintiffs also argued that VanSoestbergen was even more
    specialized than an ordinary nurse anesthetist because he
    belonged to the hospital’s “Baby Heart Team” that focused
    on care for young children.
    Id. at 4–5.
    ¶ 19         In its thorough analysis, the Court of Appeals began with the trial court’s
    recognition of our decision in Daniels, which in turn was premised on our decision in
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    Byrd, as the trial court excluded plaintiffs’ proffered expert testimony in support of
    their claim against defendant VanSoestbergen that the CRNA “breached a standard
    of care by agreeing to mask inhalation with sevoflurane.” Id. at 5. The Court of
    Appeals explained that “[t]he trial court concluded that a nurse may be liable for
    improperly administering a drug, but not for breaching a duty of care for planning
    the anesthesia procedure and selecting the appropriate technique or drug protocol.”
    Id.
    ¶ 20         The lower appellate court continued its examination by citing Byrd, observing
    that “[n]early a century ago, a plaintiff sought to hold a nurse liable for decisions
    concerning diagnosis and treatment.” Id. The Court of Appeals attributed guidance
    from Byrd in recalling notable principles from our opinion in that case:
    Our Supreme Court declined to recognize the
    plaintiff’s legal claim [in Byrd], explaining that “nurses, in
    the discharge of their duties, must obey and diligently
    execute the orders of the physician or surgeon in charge of
    the patient.” The Court held that the “law contemplates
    that the physician is solely responsible for the diagnosis
    and treatment of his patient. Nurses are not supposed to
    be experts in the technique of diagnosis or the mechanics
    of treatment.”
    Id. at 6 (quoting Byrd, 
    202 N.C. at
    341–42). Upon remarking that “[s]ince Byrd, this
    [c]ourt repeatedly has rejected legal theories and claims based on nurses’ decisions
    concerning diagnosis and treatment of patients,” 
    id.,
     the lower appellate court
    replicated the type of language which it employed in Daniels in rendering the
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    following observations as the Court of Appeals determined that the trial court did not
    commit error:
    In short, as this [c]ourt repeatedly has held in the
    last few decades, trial courts (and this [c]ourt) remain
    bound by Byrd, despite the many changes in the field of
    medicine since the 1930s. Thus, the trial court properly
    determined      that    Plaintiffs’   claims   based     on
    VanSoestbergen’s participation in developing an
    anesthesia plan for Amaya are barred by Supreme Court
    precedent.
    We acknowledge that Plaintiffs have presented
    many detailed policy arguments for why the time has come
    to depart from Byrd. We lack the authority to consider
    those arguments. We are an error-correcting body, not a
    policy-making or law-making one. And, equally important,
    Byrd is a Supreme Court opinion. We have no authority to
    modify Byrd’s comprehensive holding simply because times
    have changed. Only the Supreme Court can do that.
    
    Id.
     (extraneity omitted).
    C. Revisiting Byrd
    ¶ 21         Having explored the evolution of the nursing industry in North Carolina in the
    context of the medical field’s promotion of, and deference to, the independent abilities
    of nurses, coupled with the North Carolina appellate courts’ concomitant recognition
    of this shift in the nine decades since Byrd as a nurse’s legal culpability appropriately
    has grown commensurate with professional responsibility, this Court deems it to be
    opportune to implement its observations articulated in Harris and to ratify the
    appropriateness intimated in Daniels and the present case by the Court of Appeals
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    to revisit Byrd in light of the increased, influential roles which nurses occupy in
    medical diagnosis and treatment. We hold that even in circumstances where a
    registered nurse is discharging duties and responsibilities under the supervision of a
    physician, a nurse may be held liable for negligence and for medical malpractice in
    the event that the registered nurse is found to have breached the applicable
    professional standard of care. To the extent that this Court’s decision in Byrd v.
    Marion General Hospital establishes a contrary principle, we reverse Byrd. We
    expressly note that our decision in the present case does not disturb in any way the
    principle enunciated in Byrd that “nurses, in the discharge of their duties,” when they
    “obey and diligently execute the orders of the physician or surgeon in charge of the
    patient,” may be held liable when “such order was so obviously negligent as to lead
    any reasonable person to anticipate that substantial injury would result to the
    patient from the execution of such order or performance of such direction.” 
    202 N.C. at 341
    .
    ¶ 22         With the reversal of this Court’s holding in Byrd and its progeny which
    systematically prevented a registered nurse from being liable for the negligent
    execution of nursing duties and responsibilities which were performed under the
    auspices of a supervising physician, we are mindful to avoid any intrusion upon the
    exclusive authority of the Legislature to reach complex policy judgments and
    consequently to enact statutory laws which are consistent with these determinations
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    with regard to the creation of new causes of action or theories of liability. While the
    Legislature established the standard for recovery in civil actions for damages for
    personal injury or death in medical malpractice claims against registered nurses
    through the collective enactment of N.C.G.S. §§ 90-21.11 through 90-21.19B,
    nonetheless, the law-making body has been silent regarding further enactments
    which refine or interpret this body of statutory law. As we earlier noted, the finite
    principle of law in Byrd which we overturn in the instant case was instituted by this
    Court in the dearth of any express and specific decree from any empowered authority
    which addressed the manner and extent of a registered nurse’s legal culpability in
    situations wherein such a nurse is subject to negligence and medical malpractice
    claims. Because we established the legal principle at issue in Byrd and no intervening
    enactment or policy has emerged to change it, we are properly positioned to reverse
    Byrd without treading upon the Legislature’s domain as we fulfill this Court’s charge
    to interpret the law.
    III.    Conclusion
    ¶ 23         This Court recognizes the impracticalities and inconsistencies of the ongoing
    application of the disputed and outdated principle in Byrd to the realities of the
    advancement of the field of medicine with regard to the ascension of members of the
    nursing profession to statuses within the medical community which should
    appropriately result in an acknowledgement of their elevated station and their
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    commensurate elevated responsibility. The expanding authority, recognition, and
    independence of nurses, which have steadily evolved as these professionals,
    exemplified by those who have achieved identified specializations and certifications,
    have sufficiently risen within the ranks of the field of medicine to earn levels of
    autonomy and influence which formerly were fully withheld. Pursuant to N.C.G.S. §
    90-171.20(7), registered nurses now have the ability, inter alia, to collaborate with
    other health care providers in determining the appropriate health care for a patient;
    to implement the treatment and pharmaceutical regimen prescribed by any person
    authorized by state law to prescribe the regimen; and to plan, initiate, deliver, and
    evaluate appropriate nursing acts. As a certified registered nurse anesthetist,
    defendant VanSoestbergen in the instant case is a beneficiary of these heightened
    responsibilities which have been accorded to registered nurses and, with these
    heightened powers and the autonomy recognized by law come heightened
    responsibilities recognized by law.
    ¶ 24         The trial record developed in this case indicates that the trial court excluded
    from evidence the proffered testimony of plaintiffs’ witness who was available to
    render expert testimony concerning CRNA VanSoestbergen’s alleged breach of the
    applicable professional standard of care. While the application of Byrd has previously
    operated to prevent the admission into evidence of such testimony pursuant to this
    Court’s announced principle in Byrd that nurses cannot be held liable for the
    CONNETTE EX REL. GULLATTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Opinion of the Court
    discharge of their duties when obeying and diligently executing the orders of a
    supervising physician due to the physician’s sole responsibility for the diagnosis and
    treatment of the patient, our reversal of this principle, as espoused in Byrd, compels
    a new trial. Accordingly, the trial court’s exclusion of plaintiffs’ expert testimony is
    reversed, and this case is remanded to the Court of Appeals for further remand to the
    trial court for a new trial.
    REVERSED AND REMANDED.
    Justice ERVIN and Justice BERGER did not participate in the consideration
    or decision of this opinion.
    Justice BARRINGER dissenting.
    ¶ 25         The issue before this Court is whether a certified registered nurse anesthetist
    (CRNA) who collaborates with a doctor to select an anesthesia treatment can be liable
    for negligence in the selection of that treatment. Since 1932, this Court has held no,
    and the legislature has never required otherwise. In judicially changing this
    standard, the three-justice majority appears to create liability without causation—
    allowing a nurse to be held liable for negligent collaboration in the treatment
    ultimately chosen by the physician. Such a policy choice should be made by the
    legislature, not merely three Justices of this Court. Accordingly, I respectfully
    dissent.
    I.   Factual Background
    ¶ 26         Plaintiffs are the guardian ad litem and the mother of the juvenile who was
    injured in this case. The juvenile suffered from a serious case of dilated
    cardiomyopathy, a heart disease. Due to the juvenile’s serious heart conditions, her
    cardiologist recommended the juvenile undergo a radiofrequency ablation procedure
    to try to regulate her heart rhythm. A doctor, who is not a party to this case, prepared
    an anesthesia treatment plan for the procedure. The anesthesia treatment plan was
    to administer sevoflurane through inhalation induction and then switch to an
    intravenous induction after the juvenile was asleep. Defendant, a CRNA, assisted
    with the procedure, collaborating with the doctor on the treatment plan and helping
    CONNETTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Barringer, J., dissenting
    to administer the anesthetic. The doctor testified that as the doctor “it is my
    responsibility” to develop and prescribe the anesthesia treatment, though he and
    defendant CRNA had independently reached the same conclusion regarding which
    anesthesia treatment plan to use.
    ¶ 27         After the juvenile received the sevoflurane, her heart rate started dropping
    significantly. The doctor provided resuscitation drugs and performed chest
    compressions for approximately twelve-and-a-half minutes. During that time, the
    juvenile suffered oxygen deprivation to her brain, resulting in cerebral palsy and
    global developmental delay. Plaintiffs sued defendants for negligence.
    ¶ 28         At trial, the trial court held that only a doctor, not a nurse, can be liable for the
    selection of an anesthesia treatment under Daniels v. Durham County Hospital Corp.,
    
    171 N.C. App. 535
     (2005). Accordingly, plaintiffs were prohibited from admitting
    evidence concerning whether defendant CRNA breached a duty of care by failing to
    recommend a different anesthetic drug or better administration technique. The trial
    court concluded that evidence of a better anesthesia treatment was not relevant
    under Rule 401 of the North Carolina Rules of Evidence because it did not make some
    fact material to the case more or less likely to be true. At the conclusion of the trial,
    the jury found that the juvenile was not injured by defendant CRNA’s negligence.
    ¶ 29         Plaintiffs appealed, arguing that the trial court erred by granting defendants’
    motion to exclude the evidence of a better anesthesia treatment. However, the Court
    CONNETTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Barringer, J., dissenting
    of Appeals held that the trial court properly allowed defendants’ motion to exclude
    evidence that defendant CRNA breached the applicable standard of care by agreeing
    to induce the juvenile with sevoflurane using inhalation since the doctor, not the
    nurse, was responsible for selecting an anesthesia treatment under Daniels. Connette
    v. Charlotte-Mecklenburg Hosp. Auth., 
    272 N.C. App. 1
    , 4–6 (2020). Further, despite
    plaintiffs’ policy arguments that the practice of medicine had evolved beyond Daniels,
    rendering it obsolete, the Court of Appeals held that it was bound by Daniels because
    Daniels followed this Court’s decision in Byrd v. Marion General Hospital, 
    202 N.C. 337
     (1932). Connette, 272 N.C. App. at 6. Thus, the Court of Appeals found no error
    in the trial court’s ruling. Id. at 6–7.
    ¶ 30          Plaintiffs then petitioned this Court, asking us to allow discretionary review of
    the case to address whether Byrd is still good law. Despite the fact that two members
    of this Court were recused in this case, review was allowed.
    II.    Standard of Review
    ¶ 31          “We review relevancy determinations by the trial court de novo before applying
    an abuse of discretion standard to any subsequent balancing done by the trial court.”
    State v. Triplett, 
    368 N.C. 172
    , 175 (2015). Thus, “[a] trial court’s rulings on relevancy
    are technically not discretionary, though we accord them great deference on appeal.”
    State v. Lane, 
    365 N.C. 7
    , 27 (2011).
    CONNETTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Barringer, J., dissenting
    III.     Analysis
    ¶ 32         “It is axiomatic that only relevant evidence is admissible at trial, while
    irrelevant evidence is inadmissible.” State v. Hembree, 
    368 N.C. 2
    , 16 (2015). Rule
    401 defines relevant evidence as “evidence having any tendency to make the existence
    of any fact that is of consequence to the determination of the action more probable or
    less probable than it would be without the evidence.” N.C.G.S. § 8C-1, Rule 401
    (2021).
    ¶ 33         Here, the trial court held that the evidence of defendant CRNA’s ability to
    suggest an alternative anesthesia treatment was inadmissible under Rule 401
    because it was not relevant to whether defendant CRNA was liable for breaching the
    standard of care. Daniels took its holding from this Court’s decision in Byrd. Daniels,
    171 N.C. App. at 538. Byrd “stressed that ‘[t]he law contemplates that the physician
    is solely responsible for the diagnosis and treatment of his patient,’ ” id. (alteration in
    original) (quoting Byrd, 
    202 N.C. at
    341–42), and so held that “nurses, in the
    discharge of their duties, must obey and diligently execute the orders of the physician
    or surgeon in charge of the patient, unless . . . such order was so obviously negligent
    as to lead any reasonable person to anticipate that substantial injury would result to
    the patient from the execution of such order or performance of such direction,” Byrd,
    
    202 N.C. at 341
    . Therefore, in accordance with Byrd, the Court of Appeals in Daniels
    CONNETTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Barringer, J., dissenting
    rejected plaintiffs’ request to hold the nurse liable “for a collaborative process with
    joint responsibility.” Daniels, 171 N.C. App. at 539.
    ¶ 34         Byrd also recognized that obviously in the absence of instruction from a
    physician, a nurse who undertakes to administer treatment when the physician is
    not present “will be held liable in damages for any failure to exercise ordinary care.”
    Byrd, 
    202 N.C. at 343
    . However, “if the physician is present and undertakes to give
    directions, or, for that matter, stands by, approving the treatment administered by
    the nurse, unless the treatment is obviously negligent or dangerous, as hereinbefore
    referred to, then in such event the nurse can then assume that the treatment is proper
    under the circumstances, and such treatment, when the physician is present,
    becomes the treatment of the physician and not that of the nurse.” 
    Id.
    ¶ 35         Plaintiffs do not dispute that, under Byrd, evidence of a better anesthesia
    treatment was not relevant because the doctor, not defendant CRNA, bore the sole
    responsibility for the selection of which treatment should be used. After all, if a
    doctor’s inaction while observing a nurse select a treatment does not waive that
    doctor’s sole responsibility for the selection of that treatment, see 
    id.,
     then that
    doctor’s collaboration with the nurse in selecting the treatment likewise cannot waive
    the doctor’s exclusive responsibility. Nor do plaintiffs argue that the anesthesia
    treatment chosen in this case “was so obviously negligent as to lead any reasonable
    person to anticipate that substantial injury would result to the patient” from it.

    Instead, plaintiffs’ sole arguments are that Byrd and its progeny should be
    overturned or limited to their facts.
    ¶ 36          “This Court has never overruled its decisions lightly.” Rabon v. Rowan Mem’l
    Hosp., Inc., 
    269 N.C. 1
    , 20 (1967) “The salutary need for certainty and stability in the
    law requires, in the interest of sound public policy, that the decisions of a court of last
    resort affecting vital business interests and social values, deliberately made after
    ample consideration, should not be disturbed except for most cogent reasons.” Potter

    Hosp., Inc., 
    237 N.C. 387
    , 391 (1953)). Accordingly, this Court faithfully adheres to
    the “doctrine of stare decisis which proclaims, in effect, that where a principle of law
    has become settled by a series of decisions, it is binding on the courts and should be
    followed in similar cases.” State v. Ballance, 
    229 N.C. 764
    , 767 (1949) (emphasis
    omitted).
    ¶ 37          Admittedly “[t]he rule of stare decisis, though one tending to consistency and
    uniformity of decision, is not inflexible.” Hertz v. Woodman,

    , 456 (1919)
    (quoting Hertz, 
    218 U.S. at 212
    ). For instance, “the doctrine of stare decisis should
    never be applied to perpetuate palpable error.” State v. Mobley, 
    240 N.C. 476
    , 487
    (1954) (emphasis omitted). “Nor should stare decisis be applied where it conflicts with
    a pertinent statutory provision to the contrary.”

    statute covering the subject matter has been overlooked, the doctrine of stare decisis
    does not apply.” 
    Id.
     (emphasis omitted). However, no such justification exists in this
    case to depart from our longstanding precedent in Byrd.1
    ¶ 38          Plaintiffs contend that Byrd conflicts with a pertinent statutory provision and
    thus should be overruled. Specifically, plaintiffs reference N.C.G.S. § 90-21.12(a),
    which states, in relevant part:
    [I]n any medical malpractice action as defined in [N.C.]G.S.
    [§] 90-21.11(2)(a), the defendant health care provider shall
    not be liable for the payment of damages unless the trier of
    fact finds by the greater weight of the evidence that the
    care of such health care provider was not in accordance
    with the standards of practice among members of the same
    health care profession with similar training and experience
    situated in the same or similar communities under the
    same or similar circumstances at the time of the alleged act
    giving rise to the cause of action . . . .
    N.C.G.S. § 90-21.12(a) (2021). “Where the language of a statute is clear, the courts
    must give the statute its plain meaning . . . .” Frye Reg’l Med. Ctr., Inc. v. Hunt, 
    350 N.C. 39
    , 45 (1999). Looking to the plain language of N.C.G.S. § 90-21.12(a), nothing
    in the statute indicates that it is providing an exhaustive list of every situation in
    which a health care provider may be liable. Instead, N.C.G.S. § 90-21.12(a) functions
    1While the majority argues that Harris v. Miller, 
    335 N.C. 379
     (1994), weakened Byrd,
    Harris cited Byrd once in an offhanded comment and then did not mention it again in the
    opinion. Id. at 389. Harris never engaged in a serious examination of the merits or reasoning
    of Byrd or further addressed it. Thus, Harris cannot be interpreted as affecting Byrd’s
    precedential value.

    Barringer, J., dissenting
    as a general liability limitation such that, regardless of other circumstances, a health
    care provider cannot be liable unless certain criteria are met; namely, unless the
    provider failed to act in accordance with the standard of care set forth in the statute.
    However, nowhere does N.C.G.S. § 90-21.12(a) state that no other limitations might
    apply to certain categories of health care providers or exempt them from liability in
    specific situations. Thus, the holding in Byrd, which functions as a specific limitation
    on the liability of nurses when treating or diagnosing patients, does not conflict with
    N.C.G.S. § 90-21.12(a).
    ¶ 39          Furthermore, N.C.G.S. § 90-21.12(a) is a broad statute that provides a general
    rule applicable to all health care providers. A more specific and thus more relevant
    statute to the issue in this case is N.C.G.S. § 90-171.20(7), which defines the scope of
    practice for nurses. Subsection 90-171.20(7) sets forth the “10 components” of “[t]he
    ‘practice of nursing by a registered nurse.’ ” N.C.G.S. § 90-171.20(7) (2021). The fifth
    and sixth components are relevant to this case. The fifth component is “[c]ollaborating
    with other health care providers in determining the appropriate health care for a
    patient but, subject to the provisions of [N.C.]G.S. [§] 90-18.2,[2] not prescribing a
    medical treatment regimen or making a medical diagnosis, except under supervision
    2  Section 90-18.2 applies specifically to nurse practitioners but does not expand their
    liability beyond the limits set forth in N.C.G.S. § 90-171.20(7). While N.C.G.S. § 90-18.2
    provides that nurse practitioners may take certain actions, it explicitly notes that the
    “supervising physician shall be responsible for authorizing” those actions. N.C.G.S. § 90-18.2
    (2021).
    CONNETTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Barringer, J., dissenting
    of a licensed physician.” N.C.G.S. § 90-171.20(7)(e). The sixth component is
    “[i]mplementing the treatment and pharmaceutical regimen prescribed by any person
    authorized by State law to prescribe the regimen.” N.C.G.S. § 90-171.20(7)(f).
    ¶ 40         Pursuant to the fifth and sixth components, a registered nurse’s practice does
    not include prescribing or implementing a medical treatment or making a medical
    diagnosis unless under the supervision of a physician. The language in N.C.G.S. § 90-
    171.20(7)(e) and (f) thus incorporates the holding of Byrd, “that the physician is solely
    responsible for the diagnosis and treatment of his patient,” Byrd, 
    202 N.C. at
    341–
    42, but a nurse may administer treatment when the “physician . . . stands by,
    approving the treatment[,]” 
    id. at 343
    . As a result, the General Statutes do not conflict
    with Byrd but are indeed consistent with it.
    ¶ 41         Additionally, while plaintiffs cite the regulations governing CRNAs passed by
    the North Carolina Board of Nursing, these regulations do not provide for a liability
    different than Byrd. A regulation passed by an administrative body cannot create a
    liability that is not authorized by statute. Rouse v. Forsyth Cnty. Dep’t of Soc. Servs.,
    
    373 N.C. 400
    , 407 (2020) (“[A]n administrative agency has no power to promulgate
    rules and regulations which alter or add to the law it was set up to administer or
    which have the effect of substantive law.” (cleaned up)).
    ¶ 42         Further, the regulations’ language does not support plaintiffs’ argument.
    Certainly, 
    21 N.C. Admin. Code 36
    .0226(b) recognizes that there will be collaboration,
    CONNETTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Barringer, J., dissenting
    defined as “a process by which the [CRNA] works with one or more qualified health
    care providers, each contributing his or her respective area of expertise,” and states
    that an “individual [CRNA] shall be accountable for the outcome of his or her actions.”
    
    21 N.C. Admin. Code 36
    .0226(b) (2020). Additionally, 
    21 N.C. Admin. Code 36
    .0226(c)
    notes that one of the responsibilities of a CRNA includes “selecting, implementing,
    and managing general anesthesia.” 
    21 N.C. Admin. Code 36
    .0226(c). However, these
    clauses are limited by the scope of practice provision in the first subsection of 
    21 N.C. Admin. Code 36
    .0226(a), which provides that
    [o]nly a registered nurse who completes a program
    accredited by the Council on Accreditation of Nurse
    Anesthesia Educational Programs, is credentialed as a
    [CRNA] by the Council on Certification of Nurse
    Anesthetists, and who maintains recertification through
    the Council on Recertification of Nurse Anesthetists, shall
    perform nurse anesthesia activities in collaboration with a
    physician, dentist, podiatrist, or other lawfully qualified
    health care provider. A [CRNA] shall not prescribe a
    medical treatment regimen or make a medical diagnosis
    except under the supervision of a licensed physician.
    
    21 N.C. Admin. Code 36
    .0226(a) (emphasis added). Once again, this regulation is
    consistent with the holding of Byrd, prohibiting CRNAs from prescribing treatments
    or making medical diagnoses, except under the supervision of a licensed physician.
    ¶ 43         Finally, plaintiffs argue that Byrd conflicts with the law of joint and several
    liability because it does not permit both a doctor and nurse to be held liable for the
    same injury. Joint and several liability, however, does not determine whether a
    CONNETTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Barringer, J., dissenting
    defendant is liable for negligence. “To recover damages for actionable negligence, a
    plaintiff must establish (1) a legal duty, (2) a breach thereof, and (3) injury
    proximately caused by such breach.” Mozingo by Thomas v. Pitt Cnty. Mem’l Hosp.,
    Inc., 
    331 N.C. 182
    , 187 (1992) (cleaned up). Joint and several liability simply
    determines how a plaintiff recovers once he proves that two or more defendants meet
    the definition of actionable negligence for the same injury. See Beanblossom v.
    Thomas, 
    266 N.C. 181
    , 186–87 (1966). Under Byrd, however, plaintiffs cannot
    establish that a nurse acts negligently in collaborating on a treatment plan with a
    doctor. Therefore, the threshold requirement for reaching joint and several liability,
    that two or more parties be negligent, was never met. Accordingly, Byrd does not
    conflict with joint and several liability.
    ¶ 44          Still, plaintiffs contend that due to developments in medicine, Byrd is now
    obsolete and should be overruled. However, adhering to the principles of stare decisis,
    this Court should not disturb settled precedent that clearly defines the liability of
    doctors and nurses when treating or diagnosing patients. Of course, the legislature,
    which is not bound by stare decisis, could have at any time in the last ninety years
    enacted a different rule of liability to account for changes in the medical profession.
    As summarized previously, it did not. Neither the General Statutes nor the
    regulations governing CRNAs conflict with Byrd’s holding. Indeed, even the majority
    recognizes that under the current regulatory framework, nurses remain under the
    CONNETTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Barringer, J., dissenting
    supervision of a licensed physician. Thus, even if a nurse’s collaboration is negligent,
    the fact that the physician makes the ultimate care decision means that the nurse’s
    negligence would not be the proximate cause of any injury. Therefore, plaintiffs’
    arguments that Byrd should be overruled or limited to its facts are not persuasive.
    ¶ 45         Furthermore, as we recognized in Parkes v. Hermann, 
    376 N.C. 320
     (2020),
    creating a new form of liability involves making “a policy judgment [that] is better
    suited for the legislative branch of government.” Id. at 326. In this case, departing
    from Byrd by expanding nurse liability would require us to determine which nurses’
    training and responsibilities are so advanced or specialized as to warrant liability
    and which nurses, if any, remain not liable under Byrd. Neither the statutes nor
    caselaw provide a clear guideline for making this determination. Further,
    dramatically expanding liability requires the type of factor weighing and interest
    balancing that are quintessential policy determinations for the legislature to make,
    not the courts. See Rhyne v. K-Mart Corp., 
    358 N.C. 160
    , 169–70 (2004). For instance,
    under this new standard, nurses may now need malpractice insurance. Regardless of
    this Court’s view on whether expanding CRNA liability is a beneficial policy, “[t]he
    legislative department is the judge, within reasonable limits, of what the public
    welfare requires, and the wisdom of its enactments is not the concern of the courts.”
    State v. Warren, 
    252 N.C. 690
    , 696 (1960) (emphasis added). “As to whether an act is
    good or bad law, wise or unwise, is a question for the Legislature and not for the
    CONNETTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Barringer, J., dissenting
    courts — it is a political question.” 
    Id.
    ¶ 46          It appears that the majority’s newly created theory holds CRNAs liable if they
    negligently collaborate with their supervising physician in choosing a treatment plan.
    Left unanswered is what constitutes adequate collaboration or what happens when
    the physician and CRNA disagree. The uncertainty created by the majority’s new
    standard highlights why such policy decisions should be left to the legislature, not
    this Court.
    ¶ 47          The legislature, as the policy making body of our government, has adopted and
    codified the holdings in Byrd in its statutes and regulations rather than supplanting
    them. Thus, the majority’s holding not only overturns this Court’s precedent without
    sufficient cause but also ignores the plain language of the statutes and regulations.
    In doing so, three Justices of this Court substitute their judgment of the public
    welfare for that of the General Assembly and create instability in the medical
    profession by striking down ninety years of precedent without providing a discernible
    standard.
    IV.    Conclusion
    ¶ 48          Both the General Statutes and the regulations governing CRNAs are
    consistent with the holdings in Byrd. Legal responsibility for treatment and
    diagnoses lies with the physician alone, not with nurses. As a result, the trial court
    correctly found that evidence of whether an alternative anesthetic treatment plan
    CONNETTE V. CHARLOTTE-MECKLENBURG HOSP. AUTH.
    2022-NCSC-95
    Barringer, J., dissenting
    should have been used was not relevant to the liability of defendant CRNA. No
    justification exists to depart from our prior holdings, especially when doing so
    involves policymaking beyond the authority of this Court, creates more questions
    than it answers, and is adopted by less than a majority of this Court. Accordingly, I
    respectfully dissent.
