Question 1
During an abdominal surgical procedure, the circulating nurse observes a break in sterile
technique by the scrub person. What is the circulating nurse's immediate priority action?
A) Document the incident in the patient's chart.
B) Inform the surgeon immediately.
C) Intervene immediately to correct the break in technique.
D) Continue to observe and assess for further breaks.
E) Cover the sterile field and notify the charge nurse.
Correct Answer: C) Intervene immediately to correct the break in technique.
Rationale: The circulating nurse's immediate priority is to protect the patient from potential
infection by addressing any break in sterile technique as soon as it is observed.
Question 2
Which of the following is the most effective method for preventing wrong-site, wrong-
procedure, wrong-person surgery?
A) Ensuring the surgical consent form is signed.
B) Verbal confirmation of the procedure by the scrub person.
C) Implementing a universal protocol, including a pre-procedure verification process and time-
out.
D) Surgeon marking the site with indelible ink.
E) Circulating nurse solely verifying the patient's identity.
Correct Answer: C) Implementing a universal protocol, including a pre-procedure
verification process and time-out.
Rationale: The Joint Commission's Universal Protocol, which includes a comprehensive pre-
procedure verification process and a mandatory time-out immediately before incision, is the
most effective strategy to prevent wrong-site, wrong-procedure, wrong-person surgery.
Question 3
A patient undergoing surgery with general anesthesia develops malignant hyperthermia (MH).
What is the priority nursing intervention?
A) Administering dantrolene sodium.
B) Applying cooling blankets.
C) Increasing oxygen flow.
D) Drawing arterial blood gases (ABGs).
E) Monitoring urine output.
Correct Answer: A) Administering dantrolene sodium.
,Rationale: Dantrolene sodium is the specific pharmacological antidote for malignant
hyperthermia and must be administered immediately upon suspicion to reverse the
hypermetabolic state.
Question 4
Which zone in the surgical suite requires surgical attire (scrubs, head cover, shoe covers) but
allows for street clothes to be worn in designated areas?
A) Restricted zone
B) Semi-restricted zone
C) Unrestricted zone
D) Sterile zone
E) Contaminated zone
Correct Answer: C) Unrestricted zone
Rationale: The unrestricted zone is the area where personnel in street clothes can interact
with those in surgical attire, often including reception desks, locker rooms, and the main
corridor outside the semi-restricted area.
Question 5
When positioning a patient for surgery, which of the following is a critical nursing consideration
to prevent nerve damage?
A) Placing all patient extremities in a neutral position.
B) Padding all bony prominences.
C) Ensuring the patient is tightly secured to the operating table.
D) Elevating the patient's head above their heart.
E) Minimizing the use of positioning devices.
Correct Answer: B) Padding all bony prominences.
Rationale: Padding bony prominences and areas where nerves are superficial helps to
distribute pressure and prevent compression or stretching of nerves, which can lead to
postoperative neuropathies.
Question 6
Which type of surgical draping technique creates a sterile field by covering the patient and
surrounding equipment, providing a barrier against microorganisms?
A) Fenestrated draping
B) Non-fenestrated draping
C) Laparotomy draping
D) Square draping
E) All of the above
,Correct Answer: E) All of the above
Rationale: Fenestrated, non-fenestrated, laparotomy, and square draping are all types of sterile
draping techniques designed to establish and maintain a sterile field.
Question 7
A surgical patient is at high risk for developing a surgical site infection (SSI). Which intervention,
if performed by the perioperative nurse, is most effective in reducing this risk?
A) Administering prophylactic antibiotics postoperatively.
B) Ensuring appropriate hair removal by clipping, not shaving.
C) Applying a sterile dressing immediately after skin closure.
D) Maintaining the operating room temperature at a high level.
E) Limiting family visitation in the PACU.
Correct Answer: B) Ensuring appropriate hair removal by clipping, not shaving.
Rationale: Hair removal by shaving creates micro-abrasions that can harbor bacteria,
increasing SSI risk. Clipping, if necessary, should be done immediately prior to surgery.
Prophylactic antibiotics are given pre-operatively.
Question 8
What is the primary purpose of a "time-out" during the universal protocol?
A) To allow the surgical team to take a break.
B) To obtain final consent from the patient.
C) To verify the correct patient, procedure, and surgical site immediately before incision.
D) To document all instruments used in the surgery.
E) To review the patient's medical history.
Correct Answer: C) To verify the correct patient, procedure, and surgical site
immediately before incision.
Rationale: The time-out is a crucial safety step where the entire surgical team pauses
immediately before skin incision to actively and verbally confirm the correct patient, site, and
procedure.
Question 9
The circulating nurse is responsible for preparing the operating room. Which action ensures
the proper functioning of the electrosurgical unit (ESU)?
A) Applying the grounding pad to a fatty area.
B) Ensuring the grounding pad is fully adhered to a large, muscular area.
C) Connecting the active electrode before turning on the ESU.
, D) Using alcohol-based solutions for skin prep around the grounding pad.
E) Placing the grounding pad over a bony prominence.
Correct Answer: B) Ensuring the grounding pad is fully adhered to a large,
muscular area.
Rationale: The ESU grounding pad must be applied to a large, clean, dry, well-vascularized,
muscular area to ensure proper electrical contact and prevent burns from current dispersion.
Question 10
Which of the following describes the proper method for opening a sterile package onto a
sterile field?
A) Open the flap closest to the body first.
B) Drop the contents onto the sterile field from a distance.
C) Open the farthest flap first, then the side flaps, and finally the nearest flap.
D) Touch the inside of the package flaps with sterile gloves.
E) Place the package directly on the sterile field before opening.
Correct Answer: C) Open the farthest flap first, then the side flaps, and finally the
nearest flap.
Rationale: Opening sterile packages by starting with the flap farthest from the body helps to
prevent reaching over the sterile field, minimizing contamination risk.
Question 11
A surgical patient develops a postoperative deep vein thrombosis (DVT). Which intervention
during the intraoperative phase is most effective in DVT prophylaxis?
A) Administering aspirin preoperatively.
B) Applying pneumatic compression devices.
C) Maintaining normothermia.
D) Elevating the surgical limb.
E) Encouraging deep breathing exercises.
Correct Answer: B) Applying pneumatic compression devices.
Rationale: Intermittent pneumatic compression devices (IPCs) are highly effective in
promoting venous return and preventing venous stasis, thereby reducing the risk of DVT during
surgery.
Question 12
Which of the following is an example of an unsafe practice regarding surgical counts?
A) Performing counts at the beginning and end of a procedure.
B) Omitting the final count if the patient's condition is critical.
