SECTION 1: PRE/POSTOPERATIVE PATIENT ASSESSMENT & DIAGNOSIS Q1 – Q6
══════════════════════════════════════
Question 1 of 50
A 67-year-old male is scheduled for an open cholecystectomy under general anesthesia.
During the preoperative assessment, he reports a history of chronic obstructive pulmonary
disease and takes fluticasone-salmeterol daily. His vital signs are stable, but he admits to
smoking one pack per day and has a productive cough each morning.
A. Proceed with surgery without additional pulmonary consultation
B. Notify anesthesia and consider postponement for optimized pulmonary status ✓ CORRECT
C. Administer a prophylactic antibiotic immediately preoperatively
D. Schedule the procedure as the first case of the day without further evaluation
Correct Answer: B
Rationale: A productive cough and active smoking significantly increase the risk of
perioperative pulmonary complications, and AORN guidelines support collaboration with
anesthesia to evaluate whether postponement for smoking cessation or bronchodilator
optimization is warranted. Option A is incorrect because ignoring suboptimal pulmonary
status violates the standard of care for preoperative risk stratification. This scenario tests
the candidate's ability to recognize when preoperative conditions warrant interdisciplinary
consultation rather than routine progression to the OR.
Question 2 of 50
A 54-year-old female underwent a total knee arthroplasty under spinal anesthesia with a
femoral nerve block. In the postanesthesia care unit, she reports severe pain unrelieved by
the block, and the circulating nurse notes that her toes are pale and cool to touch compared
with the contralateral extremity.
,A. Elevate the operative leg above heart level to promote venous return
B. Apply a compression dressing more tightly to control suspected bleeding
C. Administer additional intravenous opioids to address breakthrough pain
D. Assess dorsalis pedis and posterior tibial pulses and notify the surgeon immediately ✓
CORRECT
Correct Answer: D
Rationale: Pale, cool toes with severe pain following total knee arthroplasty are classic signs
of compromised distal perfusion that may indicate vascular injury or compartment syndrome,
requiring immediate pulse assessment and surgeon notification per Alexander's Care of the
Patient in Surgery. Option A is incorrect because elevation without first ruling out acute limb
ischemia could further compromise perfusion and delay critical intervention. Early
recognition of neurovascular compromise is essential to prevent irreversible tissue damage
in orthopedic surgery patients.
Question 3 of 50
A 72-year-old patient with a body mass index of 32 is scheduled for a lengthy lumbar spinal
fusion in the prone position. During the preoperative skin assessment, the nurse notes
reddened intact skin over the sacrum and bilateral heels from a recent extended hospital stay.
A. Implement pressure-redistribution surfaces and document high risk for intraoperative
pressure injury ✓ CORRECT
B. Massage the reddened areas with lotion to improve circulation before positioning
C. Place the patient in the lateral position to avoid pressure on the sacrum
D. Apply adhesive film dressings to the sacrum and heels to prevent further breakdown
Correct Answer: A
Rationale: Nonblanchable erythema over bony prominences indicates stage 1 pressure injury
and high risk for intraoperative pressure injury progression, which requires
pressure-redistribution surfaces and documentation per AORN guidelines for positioning.
Option B is incorrect because massaging reddened tissue can cause deep tissue damage and
is contraindicated in pressure injury prevention. The perioperative nurse must anticipate
positioning-related risks and implement protective interventions before the patient enters the
OR.
Question 4 of 50
A 68-year-old patient on chronic warfarin therapy for atrial fibrillation is scheduled for an
elective inguinal hernia repair. The preoperative laboratory results reveal an INR of 3.2, and
the patient took his usual dose of warfarin last evening.
A. Proceed with surgery and request fresh frozen plasma on standby
B. Administer vitamin K intravenously in the preoperative holding area
, C. Contact the surgeon and anesthesia provider to discuss postponement and reversal
planning ✓ CORRECT
D. Cancel the case indefinitely and reschedule only after warfarin discontinuation for one
week
Correct Answer: C
Rationale: An INR of 3.2 exceeds the safe threshold for elective hernia repair and requires
collaboration with the surgeon and anesthesia provider to determine whether reversal or
postponement is appropriate, consistent with perioperative anticoagulation management
standards. Option A is incorrect because proceeding with an elevated INR significantly
increases bleeding risk without evidence of clinical necessity. The perioperative nurse serves
as the gatekeeper for safe surgical progression by ensuring laboratory values are addressed
before incision.
Question 5 of 50
A 4-year-old child with spina bifida is scheduled for urologic reconstruction. The preoperative
questionnaire indicates multiple previous surgeries and a known banana and avocado allergy,
but no latex allergy is documented.
A. Document the food allergies and proceed with standard surgical supplies
B. Implement a latex-safe environment and alert all team members to the high-risk profile ✓
CORRECT
C. Pre-medicate with diphenhydramine and corticosteroids and use standard gloves
D. Postpone surgery until formal latex allergy testing can be completed in the outpatient
setting
Correct Answer: B
Rationale: Children with spina bifida and concurrent banana or avocado allergies have a
well-documented cross-reactivity with latex, necessitating a latex-safe environment and team
notification per AORN guidelines for allergy management. Option A is incorrect because
failure to recognize the latex-fruit syndrome cross-reactivity places the patient at high risk for
intraoperative anaphylaxis. The perioperative nurse must synthesize seemingly unrelated
allergy data to identify hidden latex sensitivity before the patient enters the OR.
Question 6 of 50
A 45-year-old patient is recovering in the PACU following an uncomplicated laparoscopic
appendectomy under general anesthesia. The patient is awake, following commands, and has
stable vital signs, but has vomited twice and reports nausea rated 8 out of 10.
A. Discharge the patient to phase II recovery since vital signs are stable
B. Administer ondansetron and discharge immediately after one episode of emesis
C. Transfer to the surgical floor for overnight observation due to refractory nausea
