GRADED A+
1. During preparation for an open cholecystectomy, which instrument should the surgical
assistant ensure is immediately available for obtaining hemostasis of small bleeding vessels?
A. Kerrison rongeur
B. Bone curette
C. Mosquito hemostat
D. Volkmann curette
Answer: C. Mosquito hemostat
Rationale: The mosquito hemostat is specifically designed to clamp small blood vessels and
achieve precise hemostasis. It is commonly used in both superficial and deep surgical fields. A
Kerrison rongeur removes bone, a bone curette scrapes bone, and a Volkmann curette is used
for tissue debridement rather than vascular control.
2. During a laparoscopic appendectomy, the surgeon requests retraction of the small bowel to
expose the appendix. Which action by the surgical assistant is most appropriate?
,A. Grasp the bowel tightly with a hemostat.
B. Retract using excessive force to improve visualization.
C. Handle the bowel gently with atraumatic graspers while maintaining adequate exposure.
D. Compress the bowel against the abdominal wall.
Answer: C. Handle the bowel gently with atraumatic graspers while maintaining adequate
exposure.
Rationale: Gentle tissue handling minimizes edema, serosal tears, and postoperative
adhesions. Atraumatic graspers are specifically designed for delicate tissue. Excessive pressure
or traumatic instruments increase the risk of bowel injury.
3. Which suture material retains the greatest long-term tensile strength and is commonly
selected for fascial closure?
A. Chromic gut
B. Vicryl
C. Monocryl
D. Polypropylene (Prolene)
Answer: D. Polypropylene (Prolene)
Rationale: Polypropylene is a nonabsorbable monofilament that maintains tensile strength
indefinitely and is commonly used when prolonged tissue support is needed. Vicryl,
Monocryl, and chromic gut are absorbable sutures that gradually lose strength.
4. During closure of a laparotomy incision, which tissue layer contributes the greatest strength
to wound closure?
,A. Skin
B. Subcutaneous tissue
C. Peritoneum
D. Fascia
Answer: D. Fascia
Rationale: The fascia provides the primary tensile strength of the abdominal wall. Proper
fascial approximation is essential to prevent wound dehiscence and incisional hernia. Skin and
subcutaneous tissues contribute little structural support.
5. Which principle best reduces the likelihood of surgical site infection?
A. Frequent glove powder use
B. Reusing contaminated instruments
C. Maintaining strict sterile technique throughout the procedure
D. Passing instruments over unsterile surfaces
Answer: C. Maintaining strict sterile technique throughout the procedure
Rationale: Adherence to aseptic technique is the most effective method for preventing
contamination and reducing surgical site infections. Any break in sterility significantly
increases infection risk.
6. During vascular surgery, the surgeon requests a vascular clamp. Which instrument is
specifically designed to minimize trauma to blood vessels?
, A. Kelly clamp
B. Kocher clamp
C. Allis clamp
D. DeBakey vascular clamp
Answer: D. DeBakey vascular clamp
Rationale: DeBakey vascular clamps are designed with atraumatic jaws that reduce
endothelial injury. Kelly, Kocher, and Allis clamps are more traumatic and are not intended for
delicate vascular structures.
7. Which patient position is commonly used for thyroid surgery?
A. Prone
B. Lithotomy
C. Lateral
D. Supine with neck extended
Answer: D. Supine with neck extended
Rationale: Neck extension improves exposure of the thyroid gland. Proper positioning also
reduces operative time and improves access while protecting the patient's airway and cervical
spine.
8. Which instrument is commonly used to remove bone during orthopedic procedures?
