Q1. A patient scheduled for a total knee arthroplasty reports a
history of MRSA infection 6 months ago. Which preoperative
intervention is most important to reduce surgical site
infection risk?
A. Administer prophylactic antibiotics 2 hours before incision
B. Shave the surgical site with a razor the night before surgery
C. Perform preoperative nasal screening and decolonization as
prescribed
D. Schedule the patient as the last case of the day
Answer: C
Rationale: Patients with a history of MRSA are at high risk for
colonization. Preoperative screening and decolonization (e.g., with
mupirocin) are evidence-based practices to reduce the risk of
surgical site infections .
,Q2. Which of the following is a correct principle of sterile
technique?
A. Sterile fields may be prepared up to 2 hours before the
procedure
B. The edges of a sterile drape are considered sterile
C. Sterile team members should face the sterile field at all times
D. Talking is prohibited in the sterile field area
Answer: C
Rationale: Sterile team members are responsible for maintaining
the integrity of the sterile field. Facing the field allows them to
visually monitor it for contamination. The edges of a drape are
considered non-sterile .
Q3. A patient undergoing a craniotomy receives mannitol
intraoperatively. Which therapeutic effect is expected?
A. Increased cerebral perfusion pressure
B. Decreased intracranial pressure
C. Increased blood pressure
D. Decreased urine output
Answer: B
Rationale: Mannitol is an osmotic diuretic. It works by creating an
osmotic gradient that pulls fluid from the brain tissue into the
bloodstream, thereby decreasing intracranial pressure (ICP) .
Q4. Surgical site marking should be performed by the:
A. Patient before coming to the hospital
B. Surgeon after the site and side (if applicable) have been
surgically prepped and draped.
C. Nurse doing the patient preoperative assessment
D. Surgeon before the patient receives any sedatives
,Answer: D
Rationale: The Universal Protocol requires that the surgical site
be marked by the surgeon, and this must be done before the
patient receives any sedatives to ensure the patient is alert and
can participate in the verification process .
Q5. A patient in the lithotomy position for a vaginal
hysterectomy develops sudden hypotension and oxygen
desaturation. What is the most likely cause?
A. Anaphylaxis to the surgical prep solution
B. Venous air embolism
C. Myocardial infarction
D. Malignant hyperthermia
Answer: B
Rationale: The lithotomy position elevates the surgical site above
the heart, creating a pressure gradient that can allow air to be
drawn into open, non-collapsed venous vessels in the surgical
field. This can lead to a venous air embolism .
Q6.
During a laparoscopic cholecystectomy, the surgeon requests the
patient be placed in reverse Trendelenburg position. Which of the
following is a priority nursing intervention for this positioning?
A. Place pillows under the knees to prevent hyperextension
B. Apply sequential compression devices before positioning
C. Secure the patient with a non-slip pad and padded shoulder
braces
D. Lower the bed to a comfortable working height for the surgeon
Answer: C
Rationale: In reverse Trendelenburg, the patient is tilted with
, head up, feet down, which increases the risk of sliding toward the
foot of the bed. Padded shoulder braces (properly placed to avoid
brachial plexus injury) and a non-slip surface are essential to
maintain safe positioning.
Q7.
Which of the following is the most appropriate method for
verifying sterility of a wrapped instrument set before opening?
A. Check that the external chemical indicator has changed color
B. Ensure the internal chemical indicator is visible through the
wrapping
C. Verify that the package has an intact seal and no signs of
moisture
D. Confirm that the sterilizer printout shows correct cycle
parameters
Answer: C
Rationale: Sterility cannot be assured if the package is torn, wet,
or compromised. While chemical indicators and printouts are
important, the first step before opening is to visually check the
integrity of the wrapper and absence of moisture, which can wick
bacteria into the package.
Q8.
A patient with a latex allergy is scheduled for an open inguinal
hernia repair. Which action should the perioperative nurse take?
