    OPINION
    ¶1     This is a medical malpractice and wrongful death case. The appeal is taken following a
    jury verdict in plaintiff's favor. The hospital appeals arguing that the judgment against it should
    be reversed outright because it cannot be liable, and the doctor appeals arguing that he is entitled to
    a new trial. We affirm.
    ¶2                                        BACKGROUND
    ¶3     On July 9, 2006, plaintiff Ted Fragogiannis, accompanied by his mother, Georgia Tagalos,
    No. 14-1788 & 14-2706 (cons.)
    went to visit a friend in Bourbonnais, Illinois. Tagalos was a long-time sufferer of asthma.
    During the car ride home, Fragogiannis noticed that his mother began wheezing and gasping for
    air. She used two different inhalers, but her condition failed to improve and she was in respiratory
    distress. Fragogiannis called 911 and arranged for an ambulance to meet them on the highway
    and take his mother to the hospital. According to the paramedics' protocol, Tagalos was taken to
    Saint James Hospital, the nearest hospital.
    ¶4     Tagalos arrived at the hospital at 1:45 p.m. and at that point she could no longer speak, but
    she was still responsive. Jennifer Mullen, a nurse, met the ambulance upon its arrival and began
    the process of emergency care. Defendant, Dr. Perry Marshall, was the emergency room's
    attending physician that day. He was summoned by the nurse to address what had become a
    respiratory emergency. Dr. Marshall was at Tagalos's bedside within minutes, but the parties
    disagree about how many minutes elapsed. Dr. Marshall instructed Dr. Julie Mills, a fourth year
    emergency resident, to see Tagalos and indicated that Tagalos might need to be intubated. Dr.
    Mills assessed the patient and determined that an emergency intubation was required. At 1:56
    p.m., eleven minutes after arriving at the hospital and while Dr. Mills was preparing for intubation,
    Tagalos became unresponsive.
    ¶5     When Dr. Mills attempted to intubate Tagalos, the patient vomited. Upon seeing how
    much vomit there was, which would prevent the necessary visual to complete the intubation, Dr.
    Marshall called for an anesthesiologist, an expert in establishing airways, to assist. The vomit
    was suctioned away and, five minutes after the first attempt, a second intubation attempt was
    made. At some point around this time, Dr. Marshall also summoned surgery in case they needed
    to surgically create an airway. The vomiting continued and the second intubation attempt was
    -2-
    No. 14-1788 & 14-2706 (cons.)
    unsuccessful. It was now 2:01 p.m. At that point, Dr. Marshall made an attempt to intubate
    Tagalos and, between the anesthesiologist and another attending physician, three or four more
    intubation attempts were made. All of them failed. Dr. Marshall ordered a cricothyrotomy—a
    surgical incision in the trachea to create an airway. Sometime between 2:07 and 2:10 p.m., the
    cricothyrotomy was performed, establishing an airway. Nonetheless, Tagalos suffered cerebral
    hypoxia, a complete deprivation of oxygen to the brain. Tagalos was effectively brain dead and
    she was taken off life support and died three days later.
    ¶6      Tagalos's son, as the special administrator of her estate, filed this case for medical
    malpractice and wrongful death. Tagalos's position is that Dr. Marshall and the hospital were
    negligent because they took approximately 25 minutes before establishing an airway despite the
    fact that the patient arrived with a respiratory emergency. The hospital and Dr. Marshall's
    respective positions were that they complied with the standard of care.
    ¶7     At trial, Plaintiff's expert, Dr. Richard Sobel testified that defendants deviated from the
    standard of care in numerous ways. Dr. Sobel testified that the doctors waited too long to initially
    attempt intubation and that, when they did attempt to intubate Tagalos, they failed to administer
    sedation or properly oxygenate her prior to the attempts. Sobel testified that Dr. Marshall should
    have concluded after the first failed attempt that Tagalos had a failed airway and ordered a
    cricothyrotomy at that time. Overall, he concluded that the failure to establish an airway while 26
    minutes of respiratory failure persisted constituted a deviation from the standard of care leading to
    Tagalos's death. Sobel also testified that the nurse was negligent because she failed to properly
    alert Dr. Marshall to the exigency of the situation. Sobel claimed that the delay to get a doctor
    involved and administer prompt care was a cause, if not the cause, of Tagalos's death.
    -3-
    No. 14-1788 & 14-2706 (cons.)
    ¶8     Dr. Sobel's testimony was challenged by the testimony of Dr. Marshall and his expert, Dr.
    Timothy Rittenberry, and by the hospital's expert Dr. James Walter. These doctors testified that
    Marshall and the hospital complied with the standard of care. These witnesses maintained that a
    complete inability to intubate is rare and that Dr. Marshall acted properly by repeatedly trying to
    intubate because performing a cricothyrotomy before those attempts were made would have been
    inconsistent with common practice. They concluded, based on the fact that there was little
    improvement in oxygenation even after the cricothyrotomy was performed, that the problem was
    not the lack of an airway. But most important to this appeal is the way in which these doctors
    were examined by plaintiff's counsel.
    ¶9     Each of the doctors was questioned relatively extensively about the Manual of Emergency
    Airway Management, a treatise about managing airways in emergency respiratory situations. The
    treatise advances a particular "failed airway algorithm" that proposes what action should be taken
    when particular symptoms are present. Plaintiff's counsel questioned the defense witnesses by
    reading them sections of the book and asking the witnesses whether they agreed with the contents.
    Plaintiff's counsel also questioned the defense witnesses about their failure to bring and present
    contrary authoritative literature on the subject. The parties dispute the propriety of that
    questioning.
    ¶ 10     Plaintiff's theories at trial were that he could recover against Dr. Marshall individually
    for his individual negligent acts, and that he could recover against the hospital because the nurse
    was negligent or because the doctor was an apparent agent of the hospital. After a seven day trial,
    the jury returned a general verdict in plaintiff's favor and against the hospital and Dr. Marshall for
    $4.7 million. These appeals are taken from that final judgment, but include considerations arising
    -4-
    No. 14-1788 & 14-2706 (cons.)
    from motions in limine and posttrial motions.
    ¶ 11    On appeal, the hospital argues here as it did in the trial court that it cannot be liable for the
    nurse's conduct because there was undisputed evidence that she summoned Dr. Marshall right
    away so she did not breach any duty. The hospital also argues that it cannot be liable because
    there was no evidence that anything Mullen did or did not do proximately caused Tagalos's death.
    The hospital further argues here as it did in the trial court that it cannot be liable for Dr. Marshall's
    conduct because he was an independent contractor and not its apparent agent. Dr. Marshall
    argues in a separate appeal that he is entitled to a new trial because of improper questioning and
    argument by plaintiff's counsel, including violations of granted motions in limine.
    ¶ 12                                         ANALYSIS
    ¶ 13                             Issues for St. James Hospital Only
    ¶ 14    Beginning with the hospital, it argues that it was entitled to a directed verdict on liability
    insofar as it concerns the conduct of Jennifer Mullen, the nurse, because there was no evidence on
    Mullen breaching the standard of care nor was there evidence that anything Mullen did or did not
    do caused Tagalos's death. Plaintiff disagrees and points to the testimony of its expert who
    concluded that Mullen failed to immediately call a doctor to the patient despite the existence of the
    respiratory emergency. Plaintiff also contends that Mullen's delay in getting the doctor to the
    patient's bed was at least a significant factor leading to Tagalos's death.
    ¶ 15    The trial court may enter a directed verdict when all of the evidence, viewed in the light
    most favorable to the nonmovant, so overwhelmingly favors the movant that no contrary ruling
    based on the evidence could ever stand. Stehlik v. Village of Orland Park, 
    2012 IL App (1st) 091278
    , ¶ 34. A directed verdict is improper where there is any evidence, together with
    -5-
    No. 14-1788 & 14-2706 (cons.)
    reasonable inferences to be drawn therefrom, demonstrating a substantial factual dispute, or where
    the assessment of credibility of the witnesses or the determination regarding conflicting evidence
    is decisive to the outcome. Susnis ex rel. Susnis v. Radfar, 
    317 Ill. App. 3d 817
    , 826 (2000). We
    review the grant or denial of a motion for a directed verdict de novo. Jones v. DHR Cambridge
    Homes, Inc., 
    381 Ill. App. 3d 18
    , 28 (2008).
    ¶ 16   To demonstrate that there is no evidence to support the plaintiff's allegations of negligence
    against Mullen, the hospital points primarily to Mullen's testimony. In various iterations, Mullen
    testified that she called for help right away and that she got help right away. This testimony was
    supported by Dr. Marshall's testimony as he acknowledged that he was notified immediately when
    Tagalos arrived and that he had been in the room for three minutes with Tagalos by the time he
    ordered a blood gas test at 1:50 p.m.
    ¶ 17   The hospital charts, prepared by Mullen, state: "MD to bedside" with the notation of 1:52
    p.m., which would have been seven minutes after Tagalos arrived at the hospital. Plaintiff seized
    upon this note in an attempt to substantiate its position that Mullen was negligent. But even if the
    doctor did not arrive at the bedside for seven minutes, that does not mean that Mullen failed to
    properly and urgently alert the doctor of the emergency. Although plaintiff's expert testified that
    there may be some concern about the proper way to call out emergency codes and how that
    unfolded in this case, his ultimate conclusion was that the actual manner in which the alert was
    made was not dispositive as long as the emergency nature of the situation was conveyed. The
    only duty that plaintiff claimed Mullen owed but breached was that she needed to alert the doctor
    of the immediate need to provide care to Tagalos. All of the evidence says she did.
    ¶ 18   Moreover, plaintiff did not, and could never have, proved that whatever delay possibly
    -6-
    No. 14-1788 & 14-2706 (cons.)
    attributable to Mullen would have affected the care Tagalos received. There was not even
    evidence that beginning the intubation process earlier would have prevented death, and intubation
    was not even attempted by the doctors immediately, they attempted ventilation first. Plaintiff
    could not prove that any delay attributable to Mullen (and there was no evidence that there was
    any) would have resulted in an earlier intubation attempt, a successful intubation attempt, or an
    earlier cricothyrotomy. Accordingly, the hospital cannot be liable on the basis of any act or
    omission by the nurse.
    ¶ 19   The other theory of liability plaintiff pursued against the hospital was that it could be liable
    for the negligence of Dr. Marshall on an apparent agency theory. Dr. Marshall was an
    independent contractor of the hospital at the time care was rendered to Tagalos.
    ¶ 20   For a hospital to be liable under the doctrine of apparent authority, a plaintiff must show:
    (1) the hospital, or its agent, acted in a manner that would lead a reasonable person to conclude that
    the individual who was alleged to be negligent was an employee or agent of the hospital; (2) where
    the acts of the agent create the appearance of authority, the plaintiff must also prove that the
    hospital had knowledge of and acquiesced in them; and (3) the plaintiff acted in reliance upon the
    conduct of the hospital or its agent, consistent with ordinary care and prudence. Gilbert v.
    Sycamore Municipal Hospital, 
    156 Ill. 2d 511
    , 525 (1993). The element of justifiable reliance is
    satisfied if plaintiff relies upon the hospital to provide complete emergency room care, rather than
    upon a specific physician. Golden v. Kishwaukee Community Health Services Center, Inc., 
    269 Ill. App. 3d 37
    , 45 (1994). In medical malpractice actions against a physician and the hospital,
    whether the emergency room physician was an apparent agent of the hospital, such that hospital
    could he held vicariously liable for physician's negligence, is a question for the jury. Id. at 524.
    -7-
    No. 14-1788 & 14-2706 (cons.)
    ¶ 21    Here, the plaintiff was seeking emergency care from the hospital itself. Plaintiff did not
    choose to be treated specifically by Dr. Marshall, the doctor was simply the attending physician in
    the emergency room that day. Neither party chose the other. Instead, it was the hospital that
    chose Dr. Marshall to treat Tagalos. Plaintiff did not even live in the area and was simply taken to
    defendant-hospital as a result of its proximity to the location where her respiratory emergency
    occurred. The hospital holds itself out as a provider of general emergency care. Tagalos had no
    way to know nor to choose who would render her care, she was in respiratory distress and could
    not speak; nor did she have time, all persons involved recognized that her need for care was
    extremely urgent. Tagalos could not have known that the people rendering care to her were not
    employees. In the end, it was the province of the jury to resolve this question of fact, which it
    properly did in plaintiff's favor.
    ¶ 22    The hospital attempted to rely on a consent form that was signed by Tagalos's son that the
    hospital uses to inform patients that its emergency room physicians are independent contractors.
    The existence of an independent contractor disclaimer in a consent form is an important factor to
    consider in deciding whether a hospital held a physician out as its agent, but it is not necessarily
    dispositive. James by James v. Ingalls Memorial Hospital, 
    299 Ill. App. 3d 627
    , 633 (1998).
    The form has no bearing on this case. Tagalos did not sign the form and never knew of its
    existence. In fact, Tagalos was already brain dead, hypoxic, by the time her son signed the
    document. By the time the form was signed, the negligent acts had already occurred. In any
    event, there was no evidence offered as to how Fragogiannis could have legally bound his mother
    by his signature. The after-the-fact "consent" is, as a matter of law, insufficient to abrogate a
    vicarious link between the hospital and the attending physician. See, e.g., S. Allan Adelman,
    -8-
    No. 14-1788 & 14-2706 (cons.)
    Fundamentals of Health Law, at (B)(2), American Health Lawyers Association Seminar, Chicago,
    IL (November 10, 2004) (collecting cases explaining that disclaimers of employee status that are
    given at the last minute or without meaningful time will not allow a hospital to avoid the
    application of apparent authority). Suffice it to say that a third party signing a consent form after
    the negligence has occurred and after the patient is brain dead would not inform any unsuspecting
    patient that the four doctors that treated the individual were independent contractors.
    ¶ 23   The hospital also complains about the jury instruction that was given on the subject of
    apparent authority, arguing that the trial court should have used language from Gilbert about the
    hospital having to hold itself out as a provider of a particular type of care to create apparent
    authority. The trial court instead gave the relevant model instruction supposedly prevailing at the
    time. We do note that, although not addressed by the parties, the Illinois Pattern Jury Instruction
    on professional negligence at least now includes the "holding out" language from Gilbert. See Ill.
    Pattern Jury Instr. Civ. 105.10. But we do not find that the hospital is entitled to any relief on this
    basis. There is no chance that a different outcome would have resulted if the instruction proffered
    by the hospital was given. In fact, if the trial court had given the instruction suggested by the
    hospital and the jury found in its favor on the question of apparent agency, we would reverse that
    finding. Plaintiff proved that the hospital held itself out as a provider of complete emergency
    room care and that Tagalos neither knew nor could she have known that Dr. Marshall was not an
    employee of the hospital. No one chose Dr. Marshall but relied upon the hospital to provide
    complete emergency room care. That is all that is required, in haec verba. The indisputable
    evidence on the subject conclusively establishes an apparent agency relationship, as a matter of
    law—under Gilbert or any other arguably applicable standard.

    ¶ 24                                    Medical Negligence
    ¶ 25    Even though we have determined the hospital can be held liable for the acts of Dr.
    Marshall, its liability is still predicated on a finding that Dr. Marshall was negligent. No one
    challenges the sufficiency of the evidence. Instead, both the hospital and Dr. Marshall himself
    offer argument to support their position that the finding of liability against Dr. Marshall should be
    vacated for things that occurred during the trial. Both of their appeals follow two main lines of
    attack on the proceedings which defendants claim entitle them to a new trial. One line of attack is
    that the court erred by allowing plaintiff's counsel to use medical literature as what they
    characterize to be substantive evidence. The other is that it was improper for plaintiff's counsel to
    suggest on multiple occasions that defendants were required to produce some sort of medical
    literature to support their defenses.
    ¶ 26   We begin with the alleged use of medical literature as substantive evidence. Prior to trial,
    defendants filed a motion in limine seeking to bar plaintiff from introducing medical literature as
    substantive evidence. The trial court granted the motion. However, defendants claim that
    plaintiff's counsel effectively circumvented that ruling by reading passages from the book to
    defense witnesses under the guise of impeachment.
    ¶ 27   In Illinois, medical literature cannot be used as substantive evidence, but can be used for
    purposes of impeachment. Downey v. Dunnington, 
    384 Ill. App. 3d 350
    , 382 (2008). The
    admission of evidence and the scope of cross-examination of expert witnesses rests within the
    sound discretion of the trial court, whose rulings will not be disturbed absent an abuse of that
    discretion. Iaccino v. Anderson, 
    406 Ill. App. 3d 397
    , 408 (2010). A learned text can be used for
    impeachment on cross-examination in any of the following three circumstances: (1) the trial
    - 10 -
    No. 14-1788 & 14-2706 (cons.)
    court takes judicial notice of the author's competence; (2) the witness concedes the author's
    competence; or (3) the cross-examiner proves the author's competence by a witness with expertise
    in the subject matter. Stapleton ex rel. Clark v. Moore, 
    403 Ill. App. 3d 147
    , 160 (2010).
    ¶ 28    Defendants do not strenuously object to the authoritativeness of the Manual of Emergency
    Airway Management or the competence of its authors, Dr. Ron Walls and Dr. Michael Murphy.
    On direct examination, plaintiff's expert, Dr. Sobel, testified about the Manual, not for the truth of
    the matters asserted therein, but to explain that he considered the Manual in arriving at his
    opinions. Dr. Sobel further testified that the authors were recognized authorities in the field of
    emergency medicine and that the Manual is "highly regarded" and the "most comprehensive
    source there is" dealing with emergency airway management. That alone might be sufficient to
    satisfy the third prong of the test for the authoritativeness of a text as set forth above. But in
    addition to that, defendants' witnesses recognized the book as a competent source, though they
    obviously disagreed that the methods set forth in book were uniform. There is no requirement
    that adverse witnesses clearly concede that the test is "authoritative." Instead, recognition that a
    text is “standard,” “well-respected,” “a very good book,” a “standard book,” and “a good source”
    are indications that the text is authoritative. See Bowman v. University of Chicago Hospitals, 
    366 Ill. App. 3d 577
    , 587 (2006). The Manual is also used as a textbook which the Stapleton court
    noted was, although not determinative, an additional indication of authoritativeness in and of
    itself. Stapleton, 403 Ill. App. 3d at 159. The Manual was properly considered authoritative in
    this case.
    ¶ 29    Moving to defendants' principal objection, how the book was used, we have to determine
    whether it was improper for plaintiff's counsel to read from the book and ask the witnesses
    - 11 -
    No. 14-1788 & 14-2706 (cons.)
    questions about its contents. First of all, it is important to note that any reading from the book was
    done on cross-examination. Defendants' witnesses offered their expert opinions and their reasons
    for reaching them under direct examination. Plaintiff then used the authoritative text to confront
    those witnesses with opposing authority in an attempt to discredit their conclusions and to test their
    expertise. Defendants never objected to the testimony as improper impeachment. Additionally,
    there is no blanket prohibition on an attorney reading the text of an authoritative treatise on
    cross-examination. For example, and although not expressly adopted in Illinois, under the
    Federal Rules of Evidence it is the statements from a learned treatise that are not excluded under
    the hearsay rule. Fed. R. Evid. 803(18). Those statements may then be called to the attention of
    a witness on cross-examination. Id. The Rule continues, "[i]f admitted, the statement may be
    read into evidence but not received as an exhibit." Id.; see also Allen v. Safeco Ins. Co. of Am.,
    
    782 F.2d 1517
    , 1520-21 (11th Cir. 1986) (stating that once a foundation was laid, counsel was
    permitted to read a statement from an authoritative article on cross-examination); Lawrence v.
    Nutter, 
    203 F.2d 540
    , 542 (4th Cir. 1953) (explaining that, to test an expert's competence, it is
    proper on cross-examination to read excerpts of an authoritative text and ask the expert whether he
    agrees or disagrees). Even materials such as videotapes that effectively dictate an authoritative
    view that is counter to the one espoused by an expert witness have been found to be properly used
    on cross-examination. See, e.g., Costantino v. David M. Herzog, M.D., P.C., 
    203 F.3d 164
    ,
    170-71 (2d Cir. 2000).
    ¶ 30   In one similar, but significantly distinguishable Illinois case, we held that a plaintiff's
    counsel should not have been allowed to impeach medical witnesses by reading text from certain
    treatises and asking whether the witnesses agreed with what was read. Brown v. Arco Petroleum
    - 12 -
    No. 14-1788 & 14-2706 (cons.)
    Products Co., 
    195 Ill. App. 3d 563
    , 570-71 (1989). But, the reason we found that to be improper
    was because the materials that were read from were never identified, no witnesses were questioned
    about the author's competence, and no witnesses were called to establish that the materials were
    authoritative. 
    Id.
     That is not the case here where the authoritativeness of the book was made
    apparent and a different view of the proper course of action was presented to make the jury
    question defendants' experts' opinions.
    ¶ 31   Moreover, when cross-examined by the content of the treatise, each of the doctors took the
    opportunity to explain why the book was not discrediting of their testimony. Dr. Marshall and the
    experts repeatedly made the jury aware of the weaknesses in the book and the witnesses were able
    to explain that the book did not really discredit their opinions because medical emergency
    situations must be handled in light of innumerable factors. For example, in one particular line of
    questioning, plaintiff's counsel basically read from the Manual to express the author's view, which
    was counter to defendants' view, that when there is a failed airway and intubation cannot be
    achieved, a cricothyrotomy should be done immediately. Referring to the authors, Dr. Marshall
    responded, "[t]hey're not discussing this case." Dr. Rittenberry similarly testified that the
    algorithm set forth in the Manual could only be viewed as a general guideline because conditions
    vary so greatly between patients and the conditions they present and doctors need to make
    numerous judgment calls in respiratory emergency situations. Dr. Walter testified that the book
    was not impeaching because it relied on experiments done only on dead people. Defendants'
    counsel had the opportunity to, and did, rehabilitate their witnesses in light of them being
    confronted by the treatise. The witnesses each had an opportunity to reiterate their opinions in the
    face of the contrary view brought about by the Manual.
    - 13 -
    No. 14-1788 & 14-2706 (cons.)
    ¶ 32    Defendants and their experts, were or should have been well aware that plaintiff intended
    to use the opinions in the book as impeachment because plaintiff made clear he would do so in
    response to a motion in limine. Defendants had in their possession Dr. Sobel's opinion statements
    and had deposed him. Even if it were valid to object to plaintiff presenting the material because
    defendants' witnesses had not read it (it is not, Iaccino, 406 Ill. App. 3d at 408), defendants and
    their experts had the opportunity before trial to become familiar with the book and either explain
    why it was not authoritative or explain why the opinions offered therein were wrong or
    inapplicable. Defendants' witnesses had every opportunity to explain why the book did not
    discredit their expert opinions in the case and to reiterate why their positions correctly reflected the
    standard of care and that it was complied with. Even if defendants could have somehow shown
    that the trial court committed error, a party is not entitled to reversal based on an erroneous
    evidentiary ruling unless the error substantially prejudiced the aggrieved party and affected the
    outcome of the case, and the party seeking reversal bears the burden of establishing prejudice.

    ¶ 33    Another objection that somewhat tracks the authoritativeness issue is whether the
    algorithm described in the book can be suitably classified as "generally accepted" to meet Illinois'
    standard for admissibility of expert methodology when the book itself acknowledges that the
    algorithm cannot be "scientifically proven." The Manual's authors acknowledge that the
    algorithm "cannot be considered to be scientifically proven as the only or even necessarily the best
    way to approach any one clinical problem or patient." The authors continue, "[r]ather, [the
    algorithms] are designed to help guide a consistent approach to both common and uncommon
    airway management situations." But the algorithm was never offered for its truth or as
    - 14 -
    No. 14-1788 & 14-2706 (cons.)
    substantive evidence of the standard of care. There was evidence adduced at trial that the Manual
    is a highly regarded, comprehensive authority on emergency airway management. To be used for
    impeachment purposes, all that is required is that the treatise be established as a reliable authority.
    Stapleton, 403 Ill. App. 3d at 160. Any shortcomings of the treatise, such as the fact that its
    content cannot be scientifically proven, should be brought out by the opposing party to
    demonstrate to the jury that the content should be afforded little weight, but that does not mean the
    material cannot be used for impeachment.
    ¶ 34    Defendants also argue that the judgment should be vacated due to plaintiff's suggestion that
    defendant's expert, Dr. Walter, should have presented a treatise or some other medical literature to
    support his opinions. However, the trial court sustained the defense's objection to this question
    and instructed the jury to "disregard any suggestion that the doctor had an obligation to bring
    literature to court." During rebuttal, plaintiff's counsel returned to this idea by stating, "at least we
    brought a book." Again the objection was sustained. This argument was not ideal, but it was
    only brought up in rebuttal in response to defendants' criticism of the book and plaintiff's failure to
    bring in the author to testify in the case.   We will not reverse a judgment due to improper
    comments by counsel unless a party has been substantially prejudiced by such comments.
    Graham v. Nothwestern Memorial Hospital, 
    2012 IL App (1st) 102609
    , ¶ 34. Here, even if some
    of the questions or comments made by plaintiff's counsel were improper, defendant has not
    demonstrated such requisite prejudice.
    ¶ 35                              Hospital's Petition for Rehearing
    ¶ 36    In its petition for rehearing, the hospital contends that it was denied a fair trial because the
    trial court denied its attempt to submit a special interrogatory to the jury and to test whether its
    - 15 -
    No. 14-1788 & 14-2706 (cons.)
    liability was based on nursing care or on an apparent agency theory. The hospital contends that
    since the jury returned a general verdict and it was not allowed to ascertain the basis on which the
    verdict was rendered, the jury could have found the hospital to be liable based on the conduct of
    Nurse Mullen, even though we have held that there was no evidentiary basis for doing so. But
    that would be entirely harmless.
    ¶ 37    Regardless of the trial court's ruling on the motion for directed verdict, the case was going
    to the jury on the same evidence with both the hospital and Dr. Marshall potentially liable. On the
    verdict form, signed by all 12 jurors, the jury found for plaintiff against both the hospital and Dr.
    Marshall. If the jury intended to hold only the hospital liable (and only based on Mullen's
    conduct), then it would have returned a verdict against only the hospital. If the jury intended to
    hold only Dr. Marshall liable, as an independent contractor, then it would have returned a verdict
    against only the doctor. Even if the jury could have somehow held the extremely perverse view
    that the hospital was liable because of only Mullen and Dr. Marshall was liable, but only as an
    independent contractor, the hospital's argument would still fail. As we already explained, the
    uncontradicted evidence at trial established an apparent agency relationship—it was established as
    a matter of law. In fact, we even explained that if the jury did not find an apparent agency
    relationship on the evidence presented we would reverse for failing to do so. Supra ¶ 23. The
    hospital was not denied a fair trial.
    ¶ 38                                      CONCLUSION
    ¶ 39    In sum, like all trials, there were certain imperfections and objectionable practices, but
    nothing that rose to the level that would warrant reversal. In response to many of defendants'
    arguments, plaintiff points out that defendants did not object or did not object on the proper basis at
    - 16 -
    No. 14-1788 & 14-2706 (cons.)
    trial. We nonetheless chose to address defendants' arguments on the merits. The errors
    complained of by defendants concern the way their witnesses were cross-examined and a comment
    made by plaintiff's counsel during rebuttal to the closing arguments, but defendant has not
    persuaded us that any of the blemishes on the proceedings impugn the integrity of the jury verdict.
    Defendants have not shown that any of the alleged errors substantially prejudiced it or affected the
    outcome. When the record is viewed as a whole, it is apparent that the verdict should stand and,
    because we find no reason to disturb the jury's verdict, we affirm.
