Questions, Correct Answers & Detailed Rationales (2026/2027)
Question 1
What is the standard procedure for draping the sterile field?
• A. Drape from the periphery toward the incision site
• B. Drape from the incision site toward the periphery
• C. Drape from the feet to the head
• D. Draping order does not matter as long as it is done quickly
Correct Answer: B. Drape from the incision site toward the periphery
Detailed Rationale: Draping should always proceed from the surgical
incision site outward toward the periphery to ensure that the sterile
field remains uncontaminated and the incision site is isolated first.
Question 2
Which of the following is considered a "self-retaining" retractor?
• A. Richardson
• B. Army-Navy
• C. Weitlaner
• D. Senn
Correct Answer: C. Weitlaner
,Detailed Rationale: The Weitlaner retractor features a locking
mechanism (ratchet) that holds the blades open, allowing the surgeon
to keep the wound retracted without manual holding.
Question 3
Where should the dispersive electrode (grounding pad) for
electrosurgery be placed?
• A. Over a bony prominence
• B. Over an area with thick hair
• C. Over a large, fleshy muscle mass
• D. Distal to the surgical site
Correct Answer: C. Over a large, fleshy muscle mass
Detailed Rationale: The grounding pad must be placed on a large, well-
vascularized muscle mass to ensure proper contact and dispersion of
electrical current, preventing patient burns. It should avoid bone, scar
tissue, or hair.
Question 4
Which of the following describes the "Taper" needle point?
• A. Used primarily for skin closure
• B. Used for delicate tissues like the intestine or peritoneum, as it
penetrates without cutting
• C. Used for dense connective tissue
• D. Used for ortho surgery only
,Correct Answer: B. Used for delicate tissues like the intestine or
peritoneum, as it penetrates without cutting
Detailed Rationale: A taper needle has a round body and a smooth
point. It separates the tissue fibers rather than cutting them, making it
ideal for friable tissue like the bowel, bladder, or muscle.
Question 5
What is the primary sign of Malignant Hyperthermia?
• A. Sudden drop in blood pressure
• B. Unexplained increase in end-tidal CO2 (etCO2) and muscle
rigidity
• C. Sudden bradycardia
• D. Excessive bleeding
Correct Answer: B. Unexplained increase in end-tidal CO2 (etCO2) and
muscle rigidity
Detailed Rationale: Malignant Hyperthermia is a life-threatening
reaction to anesthesia. An early clinical sign is an unexplained rise in
end-tidal CO2, followed by tachycardia and muscle rigidity.
Question 6
What is the purpose of the biological indicator in an autoclave?
• A. To monitor the pressure of the machine
• B. To ensure the steam reached the temperature required to kill
bacterial spores
• C. To clean the internal pipes of the autoclave
, • D. To verify the weight of the trays
Correct Answer: B. To ensure the steam reached the temperature
required to kill bacterial spores
Detailed Rationale: Biological indicators (usually Geobacillus
stearothermophilus) are used to confirm that the sterilization process
successfully killed the most resistant bacterial spores, thereby ensuring
sterility.
Question 7
Which of the following is a non-absorbable suture?
• A. Chromic gut
• B. Vicryl
• C. Prolene (Polypropylene)
• D. Monocryl
Correct Answer: C. Prolene (Polypropylene)
Detailed Rationale: Prolene is a synthetic, non-absorbable
monofilament suture often used in vascular and cardiac surgery
because it creates minimal tissue reaction and maintains tensile
strength.
Question 8
When prepping a patient's skin for surgery, the scrub should begin:
• A. At the edges and work toward the incision
• B. At the incision site and work outward in a circular motion
• C. At the head and work toward the feet
