1. Who is primarily responsible for obtaining the patient’s informed consent for
a surgical procedure?
A. The surgeon
B. The circulating nurse
C. The nurse practitioner
D. The anesthesiologist
Answer: A
Rationale: The surgeon is responsible for explaining the procedure, risks, and benefits.
The nurse may witness the signature but cannot provide the initial consent information.
2. A patient scheduled for surgery mentions an allergy to bananas and
avocados. What should the nurse suspect?
A. Iodine allergy
B. Penicillin sensitivity
C. Lactose intolerance
D. Latex allergy risk
Answer: D
Rationale: Cross-reactivity exists between certain foods (bananas, avocados, kiwi) and
latex due to similar protein structures.
,3. Which medication is typically administered to treat Malignant Hyperthermia?
A. Epinephrine
B. Atropine
C. Dantrolene
D. Naloxone
Answer: C
Rationale: Dantrolene is a muscle relaxant that specifically treats the life-threatening
hypermetabolic state of malignant hyperthermia.
4. In the intraoperative setting, which role is responsible for maintaining the
sterile field and passing instruments?
A. Circulating nurse
B. Anesthesia provider
C. Surgical technologist or Scrub nurse
D. Charge nurse
Answer: C
Rationale: The scrub nurse or surgical technologist works within the sterile field, whereas
the circulating nurse stays in the non-sterile area.
5. What is the priority nursing action for a patient who has just arrived in the
PACU?
A. Assessing surgical site drainage
B. Measuring urine output
C. Checking airway patency and respiratory status
D. Assessing pain level
Answer: C
Rationale: Airway and breathing are the highest priorities according to ABCs (Airway,
Breathing, Circulation) in the immediate post-operative period.
, 6. What is the standard NPO duration for clear liquids before an elective surgery
according to ASA guidelines?
A. 2 hours
B. 4 hours
C. 6 hours
D. 8 hours
Answer: A
Rationale: ASA guidelines allow clear liquids up to 2 hours before surgery, while a light

sees loops of bowel protruding. What is this called?
A. Evisceration
B. Infection
C. Adhesion
D. Dehiscence
Answer: A
Rationale: Evisceration is the protrusion of internal organs through a surgical wound.
Dehiscence is merely the opening of the wound edges.
8. What is the primary purpose of using an incentive spirometer post-
operatively?
A. To increase heart rate
B. To measure oxygen saturation
C. To prevent atelectasis
D. To reduce surgical site pain
Answer: C
Rationale: Incentive spirometry encourages deep breathing, which helps expand alveoli
and prevent lung collapse (atelectasis).
