    OPINION
    This case was tried before a jury in the Circuit Court in Davidson
    County on two issues to-wit:       (1) informed consent and (2) professional
    negligence.
    On the issue of informed consent the trial court directed a verdict for
    the defendant at the conclusion of the plaintiff's proof.       On the issue of
    professional negligence a mistrial was declared when the jury was unable to
    agree on a verdict.
    The case is now before this court on the sole issue of informed consent.
    Plaintiff Patricia Ashe was diagnosed with breast cancer in 1988. She
    underwent a double mastectomy and chemotherapy. In July of 1993 chest x-ray
    and CT scan confirmed the presence of cancer in her left lung. As a result,
    doctors performed surgery at Baptist Hospital on July 30, 1993 to remove the
    upper portion of her left lung. She resumed chemotherapy under the care of Dr.
    Michael Kuzur. Dr. Kuzur was also consulting with the defendant, Dr. Steven
    L. Stroup regarding the possible need for radiation therapy. At this time the
    physicians were unable to determine with certainty whether her lung cancer was
    metastatic from her 1988 breast cancer or was primary lung cancer unrelated to
    the previous breast cancer. If Mrs. Ashe suffered from primary lung cancer,
    radiation therapy would significantly increase her chances for survival for five
    years and beyond.
    Radiation therapy involves the use of a photon beam to kill cancer
    cells. Radiation, however, causes chemical changes to both normal cells and
    cancer cells. The intent for use of this therapy is to cause only sublethal damage
    to the normal cells but lethal damage to the cancer cells which are less resistant
    -2-
    to radiation.
    On her first visit to Dr. Stroup Mrs. Ashe received a complete
    explanation of the procedure and went through a "dress rehearsal" of radiation
    therapy.
    Thereafter Mrs. Ashe submitted herself to radiation therapy. In this
    case Mrs. Ashe sustained radiation injury to her spinal cord resulting in paralysis
    of her lower extremities.
    All expert witnesses agreed that any patient undergoing such radiation
    therapy is at some risk for spinal cord injury. Plaintiff's expert, Dr. Carlos Perez,
    testified that this risk at the dosage received by Mrs. Ashe was from one to two
    percent. Other medical testimony asserted this percentage to be much smaller,
    but, for the purpose of reviewing the trial court action in directing a verdict for
    Dr. Stroup we are required to accept the testimony of Dr. Perez.
    It is admitted that Dr. Stroup did not inform Patricia Ashe of this risk
    of spinal cord injury prior to administering radiation therapy.
    Plaintiff testified both by pre-trial deposition and at the trial. She was
    questioned in deposition as to what she would have decided about radiation
    therapy had she been informed of the possibility of spinal cord injury. At trial
    she testified again on the same subject.         Her testimony at trial differed
    significantly from her previous testimony by deposition and at the conclusion of
    the plaintiff's proof the trial court directed a verdict against her on the informed
    consent issue applying the "rule of cancellation" stated in Taylor v. Nashville
    Banner Publishing Co., 
    573 S.W.2d 476
    , 482 (Tenn. Ct. App. 1978). Says the
    trial judge:
    The court however, does grant your motion on the issue of
    informed consent on the same basis that you made for Dr.
    Perez. It's the opinion of the court that the plaintiff has
    irreconcilably and totally contradicted herself in her
    deposition and in testimony here today. So I will grant the
    motion on the issue of informed consent.
    -3-
    We are thus called upon in this appeal to answer three pertinent
    questions:
    1.   Did the plaintiff's proof offered at trial present a jury question as
    to whether or not Dr. Stroup obtained "informed consent" of Patricia Ashe under
    the standards of T.C.A. 29-6-118 before administering radiation therapy.
    2.   If a jury question is presented as to "informed consent" is the
    plaintiff's only burden as to causation to establish that the radiation therapy in
    fact caused the paralysis.
    3.   If, in addition to radiation-paralysis causation, plaintiff must
    further prove causation in a consent context, does the "rule of cancellation"
    justify a directed verdict against her.
    I.        Did the plaintiff's proof offered at trial present a jury question
    as to whether or not Dr. Stroup obtained "informed consent"
    of Patricia Ashe under the standards of T.C.A. 29-6-118
    before administering radiation therapy.
    Plaintiff's qualified expert Dr. Carlos Perez testified that the standard
    of care in procuring informed consent required the disclosure by Dr. Stroup of
    the small but potentially catastrophic risk of spinal cord injury from radiation
    therapy. Although his testimony is hotly disputed by expert witnesses offered
    for the defendant, we are reviewing a directed verdict for the defendant wherein
    the evidence must be construed most favorably to the plaintiff. Cecil v. Hardin,
    
    575 S.W.2d 268
     (Tenn. 1978).
    In discussing informed consent this court stated in German v.
    Nichopolous, 
    577 S.W.2d 197
    , 202 (Tenn. Ct. App. 1978):
    Liability predicated on the doctrine of informed consent is
    not dependent upon the existence of negligence in the
    performance of a physical act. Liability is predicated upon
    negligence of the physician in the failure to reasonably
    advise the patient regarding the treatment recommended.
    This particular language is reiterated by the court of appeals in Bryant
    v. Bauguss, 
    1996 WL 465539
     (Tenn. App. 1996) and in Blanchard v. Kellum,
    -4-
    
    1997 WL 147525
     (Tenn. App. 1997). We note that permission to appeal in
    Blanchard v. Kellum was granted by the Supreme Court on September 29, 1997.
    The reference in Nichopolous to the physician failing to reasonably
    advise the patient regarding the treatment recommended in terms of "negligence"
    is inconsistent with Cardwell v. Bechtol, 
    724 S.W.2d 739
     (Tenn. 1987). Said the
    supreme court in Cardwell:
    Although this provision is part of the malpractice statute
    and while determining whether the Defendant failed to obtain
    informed consent is dependent upon the standard of care of
    the profession or specialty, if informed consent is not
    effectively obtained, the defendant's departure from the
    standard of care is not negligence but battery because "the
    doctrine of battery [is] applicable to cases involving
    [treatment] performed without informed or knowledgeable
    consent." Ray v. Scheibert, 
    484 S.W.2d 63
    , 71 (Tenn.App.),
    cert. denied (Tenn.1972)(emphasis in original). As observed
    in Lanford v. York, 
    224 Tenn. 503
    , 
    457 S.W.2d 525
     (1970),
    malpractice "'is based on lack of care or skill in the
    performance of services contracted for, and [battery] on
    wrongful trespass on the person regardless of the skill
    employed. The assertion of one is the denial of the other.'"
    224 Tenn. at 510-511, 457 S.W.2d at 528 (citation omitted).
    [9] We found it necessary to note this because the
    Plaintiffs alleged and the trial court instructed the jury on
    "negligent failure to obtain informed consent." T.C.A. § 29-
    26-118 does not codify or otherwise create such a cause of
    action. While the determination of the effectiveness of
    consent cannot be made without expert testimony on the
    standard of care concerning what information is usually
    supplied to enable a patient to give informed consent,
    considering both the seriousness of the treatment and any
    expression of concern by the patient, failure to give such
    information is not the type of omission that results in
    negligence, but rather it negates consent for the treatment.
    Without consent, the treatment constitutes a battery.
    [10] Under the case law, the correct analysis in our
    opinion is that if the evidence shows that the person had the
    capacity to consent, then the question becomes whether the
    consent given was effective because it was based upon
    adequate information on which to make the decision to
    submit to treatment; if not, then a battery results, but if so,
    then the question becomes whether the defendant
    subsequently did anything negligent in the administration of
    the treatment for which consent was obtained, proof of which
    is controlled by T.C.A. § 29-26-115. The trial court's
    instruction on negligent failure to obtain informed consent
    -5-
    was, therefore, error, but in view of the verdict and our
    decision in this case, it was harmless error. Rule 36,
    T.R.A.P.
    [11] These theories, battery and malpractice, are not
    ordinarily inconsistent, and no election of remedies is
    generally required; if a battery exists, then malpractice may
    not necessarily be reached, but if no battery can be shown,
    then the issue clearly emerges as one of malpractice. This
    distinction between battery and malpractice (as a form of
    negligence) is consistently recognized in the case law.
    Cardwell v. Bechtol, 
    724 S.W.2d 739
    , 750 (Tenn. 1987).
    Thus we come to the line that must be drawn between that which is
    required by the standard of care to be disclosed to the patient and that which is
    not so required.   This inexact and case-sensitive line was discussed by the
    supreme court in the recent case of Shadrick v. Coker, 
    963 S.W.2d 726
     (Tenn.
    1998). Said the court:
    [10] This is not to suggest, however, that a health care
    provider is required to enumerate in detail every aspect of the
    proposed treatment or procedure or discuss every possible
    thing that might go wrong in an effort to obtain the patient's
    informed consent. "In the first place, to do so is humanly
    impossible. In the second place, if all the gory details of a
    proposed surgery were graphically explained to every patient
    and all possible medical maladies that might result were
    enumerated, we doubt that a lay person would have the
    stomach to listen to it all; and if the patient did, would
    probably be in such a fearful state that no rational decision
    could be made." Longmire v. Hoey, 
    512 S.W.2d 307
    , 310
    (Tenn.App.1974). Accordingly, health care providers are
    generally not required to disclose risks that are not material,
    such as those that are extremely unlikely to occur or one that
    a reasonable patient would not care to know due to its
    insignificance; risks that are obvious or already known by the
    patient; risks that are unforeseeable or unknowable; or where
    the patient's medical condition renders discussion of the risks
    and benefits of the treatment or procedure impossible or
    medically inadvisable, such as in an emergency where the
    patient is unconscious or otherwise incapable of consenting,
    or where full disclosure would be detrimental to the patient's
    total care, i.e., the patient is unduly alarmed or apprehensive
    to start with and additional information would overload the
    patient and jeopardize his or her physical or emotional well-
    being.
    -6-
    
    963 S.W.2d 726
    , 733 (Tenn.1988).
    The court of appeals in Longmire v. Hoey, 
    512 S.W.2d 307
     (Tenn. Ct.
    App. 1974) observed:
    We are cited to cases from other jurisdictions where the
    failure to advise of a 1% risk has been the basis of a finding
    of liability. Bowers v. Talmage (1963 Fla.App.) 
    159 So. 2d 888
    , Canterbury v. Spence and Washington Hospital Center
    (1972) 150 U.S.App.D.C. 263, 
    464 F.2d 772
    .
    [2] We have no particular quarrel with the results
    reached in other jurisdictions, but we are not of the opinion
    that proof of any particular percentage figure is determinative
    of whether or not a plaintiff has made out a prima facie case.
    We are of the opinion that the serious nature of the risk
    involved is paramount to any percentage figure of
    occurrence.
    Of course, the percentage of risk of occurrence must be
    considered along with the nature of that which is risked. In
    the reported cases which have held that failure to advise of a
    1% risk or such other low percentage may be a basis for
    liability, we also find that which was risked was of a
    devastating nature; such as complete or partial paralyses,
    blindness or deafness. We readily admit that when such is
    the nature of the risk reasonable minds might differ on
    whether or not the patient should have been advised of that
    risk. There are those who would risk death itself before a
    lifetime of paralyses or blindness. Others might prefer to
    suffer a certain amount of pain rather than risk such
    disastrous results. The occurrence risked may itself be of
    great magnitude while the percentage of its occurrence may
    be small.
    
    512 S.W.2d 307
    , 310 (Tenn. Ct. App. 1974).
    Both the Longmire court and the supreme court in Shadrick refer to the
    landmark case of Canterbury v. Spence & Washington Hospital Center, 15
    U.S.App.D.C. 263, 
    464 F.2d 772
     (1972). The facts underlying Canterbury are
    parallel to the facts in this case.   In discussing the crucial question, the
    Canterbury court says:
    Dr. Spence further testified that even without trauma
    paralysis can be anticipated "somewhere in the nature of one
    percent" of the laminectomies performed, a risk he termed "a
    very slight possibility." He felt that communication of that
    risk to the patient is not good medical practice because it
    -7-
    might deter patients from undergoing needed surgery and
    might produce adverse psychological reactions which would
    preclude the success of the operation.
    ...
    We reverse. The testimony of appellant and his mother that
    Dr. Spence did not reveal the risk of paralysis from the
    laminectomy made out a prima facie case of violation of the
    physician's duty to disclose which Dr. Spence's explanation
    did not negate as a matter of law.
    
    464 F.2d 772
    , 778 (1972).
    Longmire did not deal with catastrophic injury but rather with a
    ureterovaginal fistula developing in an area not associated with the surgery.
    When considered in the context of the case at bar the Longmire dicta is
    revealing:
    In the reported cases which have held that failure to advise of
    a 1% risk or such other low percentage may be a basis of
    liability, we also find that which was risked was of a
    devastating nature; such as complete or partial paralysis, . .
    .
    
    512 S.W.2d 307
    , 310 (Tenn. Ct. App. 1974).
    Against this background we consider T.C.A. 29-26-118 specifically
    entitled "proving inadequacy of consent." In cases involving informed consent
    Tennessee has long followed the "battery" rule. Cardwell v. Bechtol, 
    724 S.W.2d 739
     (Tenn. 1987); Ray v. Scheibert, 
    484 S.W.2d 63
     (Tenn. Ct. App.
    1972); Lanford v. York, 
    244 Tenn. 503
    , 
    457 S.W.2d 525
     (1970).
    Before undertaking a medical procedure it is necessary for the doctor
    to adequately inform the patient as to serious risks and problems that might
    develop from the procedure. This includes serious risks that are inherent in the
    procedure itself no matter how carefully this procedure is performed. Under the
    Longmire observations a small risk of chicken pox would be one thing and a
    small risk of small pox quite something else. We need go no further in the case
    at bar than hold that the catastrophic nature of paralysis presents a jury question
    -8-
    under the facts of this case when a duly qualified expert witness testifies that the
    applicable standard of care for informed consent requires the disclosure of the
    risks.
    II.       If a jury question is presented as to "informed consent" is
    the plaintiff's only burden as to causation to establish that
    the radiation therapy in fact caused the paralysis.
    Plaintiff asserts that in those jurisdictions like Tennessee following the
    "battery" rule in cases involving informed consent the only causation issue is
    whether or not the procedure caused the result. Thus in this case did the
    radiation treatment cause the spinal cord injury resulting in paralysis.
    In his brief, the defendant takes the following position:
    This case law highlights the confusion that exists in the
    body of law regarding informed consent in the medical arena
    and whether--or when--a claim sounds in battery or
    negligence. Dr. Stroup respectfully submits that a distinction
    must be made between two potential kinds of informed
    consent claims:
    1. When the physician utterly fails to inform the patient
    of the nature of the procedure and the significant risks most
    likely associated with it; and
    2. When the physician fails to inform the patient of a
    remote (even though consequential) risk of the procedure,
    but otherwise obtains the patient's informed consent.
    Otherwise, a no-fault analysis will prevail and allow a
    patient to recover damages when that patient has been
    unfortunate enough to experience a very remote risk that
    occurred in the absence of negligence. If the patient consents
    to the touching, but a remote yet undisclosed risk is realized,
    the jury should be allowed to determine whether that patient,
    or a reasonable patient, would have nonetheless consented
    even if the remote risk had been disclosed as part of the
    informed consent discussion.
    Otherwise, the fear expressed in Shadrick and others
    will be realized. Healthcare providers will feel required to
    disclose risks "that are extremely unlikely to occur . . .; risks
    that are unforeseeable or unknowable; or where the patient's
    medical condition renders discussion of the risks and benefits
    of the treatment and procedure impossible or medically
    inadvisable, . . ., or where full disclosure would be
    detrimental to the patient's total care, i.e., the patient is
    unduly alarmed or apprehensive to start with an additional
    -9-
    information would overload the patient and jeopardize his or
    her physical or emotional well-being." (Slip Op., at p. 11.)
    In the present climate of experts-for-hire, any physician
    would be foolhardy to exercise discretion and avoid so-called
    "full disclosure" even if the patient's interests may require it.
    On July 13, 1998 the Supreme Court released its opinion in Frances
    Blanchard v. Arlene Kellum, D.D.S., No. 02-S-01-9709-CV-00083. The court
    therein makes the distinction asserted by the defendant in this case. Says the
    Supreme court in Blanchard:
    The plaintiff has alleged that she did not give Dr.
    Kellum permission to pull thirty-two teeth during the office
    visit giving rise to this litigation. The plaintiff contends that
    her claim on appeal is predicated upon a theory of "a
    violation of plaintiff's person" or "an actionable battery" and
    is not "related to medical or professional negligence." She
    argues that expert testimony should not be required merely
    to show whether Dr. Kellum procured permission to perform
    the extractions.
    We believe that there is a distinction between: (1) cases
    in which a doctor performs an unauthorized procedure; and
    (2) cases in which the procedure is authorized but the patient
    claims that the doctor failed to inform the patient of any or
    all the risks inherent in the procedure. Performance of an
    unauthorized procedure constitutes a medical battery. A
    simple inquiry can be used to determine whether a case
    constitutes a medical battery: (1) was the patient aware that
    the doctor was going to perform the procedure (i.e., did the
    patient know that the dentist was going to perform a root
    canal on a specified tooth or that the doctor was going to
    perform surgery on the specified knee?); and, if so (2) did the
    patient authorize performance of the procedure? A plaintiff's
    cause of action may be classified as a medical battery only
    when answers to either of the above questions are in the
    negative. If, however, answers to the above questions are
    affirmative and if the plaintiff is alleging that the doctor
    failed to inform of any or all risks or aspects associated with
    a procedure, the patient's cause of action rests on an informed
    consent theory.
    ...
    Lack of informed consent in a medical malpractice
    action under Tenn. Code Ann. § 29-16-118 operates to
    negate a patient's authorization for a procedure thereby
    giving rise to a cause of action for battery. Cardwell v.
    Bechtol, 
    724 S.W.2d 739
    , 750-51 (Tenn. 1987). There is,
    -10-
    however, no prior authorization or consent in a medical
    battery case to be negated by expert testimony. The primary
    consideration in a medical battery case is simply whether the
    patient knew of and authorized a procedure. This
    determination does not require the testimony of an expert
    witness.
    Frances Blanchard v. Arlene Kellum, D.D.S., No. 02-S-01-9709-CV-00083,
    slip op. at 4-6 (Tenn. July 13, 1998) (emphasis added).
    In the case at bar there is no assertion of a "medical battery" case as
    defined in Blanchard since not only was the radiation therapy authorized by the
    plaintiff but in fact was "dress rehearsed" before the procedure was undertaken.
    We are dealing here only with lack of informed consent under T.C.A. § 29-16-
    118 and not with a Blanchard defined "medical battery" case. Thus we refer to
    the rule in Shadrick.
    The supreme court has stated:
    [5] A cause of action based on the lack of informed consent
    stems from the premise that a competent patient should be
    allowed to formulate an intelligent, informed decision about
    surgical or other treatment procedures the patient undertakes.
    Housh v. Morris, 
    818 S.W.2d 39
    , 41 (Tenn.App.1991). The
    basic policy consideration which supports the recognition of
    the cause of action for lack of informed consent has been
    explained as follows:
    The root premise is the concept fundamental in
    American jurisprudence that 'every human being
    of adult years and sound mind has a right to
    determine what shall be done with his own body .
    . . .' True consent to what happens to one's self is
    the informed exercise of a choice, and that entails
    an opportunity to evaluate knowledgeably the
    options available and the risks dependant upon
    each. The average patient has little or no
    understanding of the medical arts, and ordinarily
    has only his physician to whom he can look for
    enlightenment with which to reach an intelligent
    decision.       from these almost axiomatic
    considerations springs the need, and in turn the
    requirement, of a reasonable divulgence by [the]
    physician to [the] patient to make such a decision
    possible. Canterbury v. Spence, 
    464 F.2d 772
    ,
    780 (D.C.Cir.1972).
    -11-
    [6-8] Accordingly, the law recognizes that a health care
    provider, such as a physician or surgeon, who proposes a
    treatment or surgical procedure has a duty to provide the
    patient with enough information about the nature of the
    treatment or procedure involved to enable the patient to make
    an intelligent decision and thereby give an informed consent
    to the treatment or procedure. See Cardwell v. Bechtol, 
    724 S.W.2d 739
    , 750 (Tenn.1987).
    Shadrick at 731.
    The position of the plaintiff that there is no causation issue except the
    cause and effect relationship between the radiation therapy and the spinal injury
    might well be correct in a Blanchard defined 'medical battery' action. It likewise
    finds support in Pennsylvania Gouse v. Cassell, 615 At.2d 331 (Penn. 1992) but
    little support elsewhere. In a lack of informed consent case under T.C.A. § 29-
    16-118, Tennessee has not so limited the causation inquiry. Nor have Tennessee
    cases articulated a causation standard directly encompassing the effect of lack of
    informed consent on the preoperative decision-making of the patient. The only
    hint comes from Longmire v. Hoey, 
    512 S.W.2d 307
    , 309 wherein the court of
    appeals observes: "Although not of itself necessarily controlling, we can not
    help but note that plaintiff never claimed that she would have made any other
    choice than the one she made, even if she had been advised of the possibility of
    a fistula developing." This hints at a subjective causation standard.
    Professor Joseph H. King, Jr. in his 1977 article: "The standard of care
    and informed consent under the Tennessee Medical Malpractice Act" vol. 44
    Tenn. Law Review 2 observed:
    Another aspect of the causation requirement deals with the
    question of whether the required disclosure would have made
    any difference in the decision to proceed with the treatment.
    Most courts and legislatures that have addressed the question
    apply an objective standard, which requires that plaintiff
    prove that a reasonable person in plaintiff's position would
    have declined the therapy had he been adequately informed.
    A few courts have adopted a subjective standard that would
    inquire whether the particular plaintiff would have consented
    had the appropriate disclosure been made.

    Recognizing the reliance of Longmire and Shadrick on preeminent
    authority of the near encyclopedic decision in Canterbury v. Spence, 
    464 F.2d 772
     (1972); and lacking further guidance from the appellate courts in Tennessee,
    we adopt the objective causation standard stated therein:
    [31] A causal connection exists when, but only when,
    disclosure of significant risks incidental to treatment would
    have resulted in a decision against it. The patient obviously
    has no complaint if he would have submitted to the therapy
    notwithstanding awareness that the risk was one of its perils.
    On the other hand, the very purpose of the disclosure rule is
    to protect the patient against consequences which, if known,
    he would have avoided by foregoing the treatment. The
    more difficult question is whether the factual issue on
    causality calls for an objective or a subjective determination.
    It has been assumed that the issue is to be resolved
    according to whether the factfinder believes the patient's
    testimony that he would not have agreed to the treatment if
    he had known of the danger which later ripened into injury.
    We think a technique which ties the factual conclusion on
    causation simply to the assessment of the patient's credibility
    is unsatisfactory. To be sure, the objective of risk-disclosure
    is preservation of the patient's interest in intelligent self-
    choice on proposed treatment, a matter the patient is free to
    decide for any reason that appeals to him. When, prior to
    commencement of therapy, the patient is sufficiently
    informed on risks and he exercises his choice, it may truly be
    said that he did exactly what he wanted to do. But when
    causality is explored at a post-injury trial with a professedly
    uninformed patient, the question whether he actually would
    have turned the treatment down if he had known the risks is
    purely hypothetical: "Viewed from the point at which he had
    to decide, would the patient have decided differently had he
    known something he did not know?" And the answer which
    the patient supplies hardly represents more than a guess,
    perhaps tinged by the circumstance that the uncommunicated
    hazard has in fact materialized.
    In our view, this method of dealing with the issue on
    causation comes in second-best. It places the physician in
    jeopardy of the patient's hindsight and bitterness. It places
    the factfinder in the position of deciding whether a
    speculative answer to a hypothetical question is to be
    credited. It calls for a subjective determination solely on
    testimony of a patient-witness shadowed by the occurrence
    of the undisclosed risk.
    [32] Better it is, we believe, to resolve the causality
    issue on an objective basis: in terms of what a prudent
    person in the patient's position would have decided if
    suitably informed of all perils bearing significance. If
    -13-
    adequate disclosure could reasonably be expected to have
    caused that person to decline the treatment because of the
    revelation of the kind of risk or danger that resulted in harm,
    causation is shown, but otherwise not.            The patient's
    testimony is relevant on that score of course but it would not
    threaten to dominate the findings. And since that testimony
    would probably be appraised congruently with the
    factfinder's belief in its reasonableness, the case for a wholly
    objective standard for passing on causation is strengthened.
    Such a standard would in any event ease the fact-finding
    process and better assure the truth as its product.
    Canterbury v. Spence, 464 F.2d at 790-791 (1972).
    III.      If in addition to radiation-paralysis causation plaintiff must
    further prove causation in a consent context, does the "rule
    of cancellation" justify a directed verdict against her.
    Since the objective standard we adopt renders the testimony of the
    plaintiff but one of the factors to be considered, the "rule of cancellation" of
    Taylor does not apply. Since this rule formed the sole basis for the trial court's
    directed verdict, the action of the trial court in this respect is reversed.
    The discrepancies between the testimony of Mrs. Ashe at her
    deposition and her testimony at trial go to her credibility as a witness and must
    be considered along with all other evidence presented to the trier of fact on the
    causation issue under an objective person standard.
    Appellee asserts error in the failure of the trial court to grant its motion
    for a directed verdict on the issue of professional negligence in this case. The
    jury was unable to reach a decision and a mistrial was declared as to this issue.
    The order granting the motion of the defendant for a directed verdict
    on the informed consent issue provides:
    After considering the argument of counsel, the pleadings
    submitted by the parties, and otherwise being sufficiently
    advised, the court denies the plaintiff's motion for new trial
    and motion for partial summary judgment, and grants the
    defendant's motion to make the directed verdict final.
    Accordingly, it is hereby ordered that the plaintiff's informed
    -14-
    consent claim is dismissed with prejudice. All other claims
    by the plaintiff are reserved and the case is hereby stayed
    pending the plaintiff's expected appeal of the directed
    verdict.
    This order as to the directed verdict on the informed consent
    claim is final and there is no just cause for delay.
    The only notice of appeal is that filed by the plaintiff which is pursuant
    to rule 54.02 of the Tennessee Rules of Civil Procedure and effectively brings
    before this court only the informed consent issue.
    The action of the trial court in directing a verdict in favor of the
    defendants on the issue of informed consent is reversed and the case is remanded
    for a new trial along with the negligence issue still pending in the trial court.
    Costs of this appeal are assessed to the appellees.
