Section 1: Patient Safety & Risk Management in Perioperative
Setting (Q1-15)
Question 1 The circulating nurse is verifying the surgical site mark with the patient
preoperatively. The mark is a clear "YES" written in the operative area, but the patient
states, "I think they're operating on my right knee, but the pain is really in my left."
What is the priority action?
A. Proceed with the right knee surgery as marked; the surgeon confirmed the site
B. Immediately stop the process, notify the surgeon, and do not proceed until site is
reconciled [CORRECT]
C. Ask the patient to sign a supplemental consent for the left knee instead
D. Document the patient's confusion and proceed with anesthesia induction
Rationale: The Universal Protocol mandates immediate cessation of the surgical
process when any discrepancy exists in patient, procedure, or site verification. The
patient's statement creates ambiguity that must be resolved by the surgeon before
proceeding. Proceeding (Option A) violates the Universal Protocol and risks wrong-
site surgery. Changing consent (Option C) without surgeon involvement is outside
nursing scope. Documenting and proceeding (Option D) is negligent and dangerous.
Correct Answer: B
Question 2 During the time-out, the team confirms the patient, procedure, and site.
Which additional element must be verified before incision per the Universal Protocol?
A. The surgeon's preference card from the previous month
B. Availability of implants, special equipment, and prophylactic antibiotic
administration within 60 minutes of incision [CORRECT]
,C. The anesthesiologist's vacation schedule
D. The circulating nurse's break rotation
Rationale: The comprehensive time-out includes verification of patient identity,
procedure, site/side, implants, special equipment, anticipated blood loss, allergies,
DVT prophylaxis, and prophylactic antibiotic timing (within 60 minutes of incision for
most antibiotics; 120 minutes for vancomycin/fluoroquinolones). The preference card
(Option A) should be reviewed preoperatively but is not part of the time-out.
Anesthesiologist schedules (Option C) and break rotations (Option D) are operational
concerns, not patient safety elements of the time-out.
Correct Answer: B
Question 3 A patient with documented latex allergy is scheduled for a hernia repair.
Which scheduling consideration is most appropriate?
A. Schedule as the last case of the day to allow thorough cleaning
B. Schedule as the first case of the day to minimize latex aerosolization from previous
cases [CORRECT]
C. Schedule between two orthopedic cases to balance the schedule
D. Latex allergy does not affect scheduling; standard precautions are sufficient
Rationale: Latex proteins can become aerosolized during procedures, particularly
when powdered gloves are used (though powder-free is now standard). Scheduling
latex-allergic patients as the first case of the day minimizes exposure to residual latex
particles in the environment. The OR must also be prepared with a latex-safe cart
containing latex-free supplies, tourniquets, gloves, and equipment. Standard
precautions (Option D) are insufficient for type I hypersensitivity.
Correct Answer: B
Question 4 The informed consent form is presented to the patient for a laparoscopic
cholecystectomy. The patient asks, "What are the risks?" The surgeon is not
immediately available. What is the appropriate nursing action?
,A. Explain the risks based on the nurse's knowledge and experience
B. Inform the patient that the surgeon must explain risks; do not proceed with the
consent process until the surgeon returns [CORRECT]
C. Have the patient sign the form and document that risks were not discussed
D. Ask the anesthesia provider to explain the surgical risks
Rationale: Informed consent requires the operating surgeon (or qualified designee
with privileges) to explain the procedure, risks, benefits, and alternatives in language
the patient understands. Nurses may witness the signature and verify that the patient
appears to understand, but they cannot provide the informed consent discussion—
that is outside nursing scope and legally the surgeon's responsibility. Having the
patient sign without discussion (Option C) is malpractice. Delegating to anesthesia
(Option D) is inappropriate for surgical risks.
Correct Answer: B
Question 5 A patient is receiving cefazolin 2g IV as surgical prophylaxis. The
procedure is expected to last 4 hours, and the patient's estimated blood loss is
anticipated to be 1500mL. When should the antibiotic be redosed?
A. No redosing is necessary; cefazolin provides coverage for the entire procedure
B. Redose when half the surgical time has elapsed
C. Redose at 3-4 hours or when blood loss exceeds 1500mL, whichever comes first
[CORRECT]
D. Redose only at the end of the procedure before closure
Rationale: Per SCIP (Surgical Care Improvement Project) and AORN guidelines,
cefazolin should be redosed at 3-4 hours (half-life ~1.8 hours) or when blood loss
exceeds 1500mL, as significant blood loss and fluid resuscitation dilute antibiotic
concentrations. Vancomycin and fluoroquinolones are exceptions with 120-minute
pre-incision windows. No redosing (Option A) risks inadequate tissue levels.
Redosing at half-time (Option B) is not evidence-based. Redosing at closure (Option
D) provides no intraoperative benefit.
Correct Answer: C
, Question 6 During the time-out for a total knee arthroplasty, the team identifies that
the prosthesis size on the preference card does not match the implant available in
the room. What is the correct action?
A. Proceed with the available implant; the preference card may be outdated
B. Verify the correct implant with the surgeon and ensure availability before incision;
if unavailable, delay surgery [CORRECT]
C. Ask the surgeon to change the surgical plan to accommodate the available
implant
D. Send someone to central supply while beginning the procedure
Rationale: The time-out is the final safety check before incision. Any discrepancy in
implants, equipment, or supplies must be resolved before proceeding. The correct
implant must be verified with the surgeon and confirmed available. Proceeding with
wrong implant (Option A) risks surgical failure. Changing the surgical plan (Option C)
is not a nursing decision. Beginning surgery while supplies are retrieved (Option D)
violates the time-out purpose and risks intraoperative delays with an open patient.
Correct Answer: B
Question 7 A patient with a history of anaphylaxis to penicillin is scheduled for open
heart surgery. Which antibiotic prophylaxis is most appropriate?
A. Cefazolin 2g IV; cross-reactivity with penicillin is minimal
B. Vancomycin 1g IV; no beta-lactam cross-reactivity [CORRECT]
C. Ampicillin-sulbactam 3g IV; broader spectrum coverage
D. No prophylaxis needed; sterile technique is sufficient
Rationale: For patients with documented anaphylaxis to penicillin, cephalosporins
(Option A) should be avoided due to potential cross-reactivity (though low, the risk is
unacceptable in anaphylaxis). Vancomycin (Option B) provides appropriate gram-
positive coverage for cardiac surgery without beta-lactam cross-reactivity. Ampicillin-
sulbactam (Option C) is a penicillin-class antibiotic and absolutely contraindicated.
No prophylaxis (Option D) significantly increases surgical site infection risk.
