Question 1
What are the three primary borders that define the anatomical
boundaries of the femoral triangle?
• A. Inguinal ligament superiorly, sartorius muscle laterally, and
medial border of the adductor longus muscle medially
• B. Pectineal ligament superiorly, rectus abdominis laterally, and
gracilis medially
• C. Iliopubic tract, femoral vein, and lacunar ligament
• D. Tensor fasciae latae, gluteus medius, and sciatic nerve
Correct Answer: A. Inguinal ligament superiorly, sartorius muscle
laterally, and medial border of the adductor longus muscle medially
Detailed Rationale: The femoral triangle is a subfascial space located in
the upper anterior thigh. Its boundaries are the inguinal ligament
(base), the medial border of the sartorius muscle (lateral border), and
the medial border of the adductor longus muscle (medial border). Its
contents include the femoral nerve, artery, and vein (NAVEL from lateral
to medial).
Question 2
,During prolonged gynecological or urological procedures performed in
the lithotomy position, compression of which nerve against the fibular
head most commonly results in foot drop?
• A. Obturator nerve
• B. Sciatic nerve
• C. Common peroneal (fibular) nerve
• D. Femoral nerve
Correct Answer: C. Common peroneal (fibular) nerve
Detailed Rationale: The common peroneal nerve winds superficially
around the neck of the fibula. In the lithotomy position, improper
padding or direct pressure from metal stirrups can compress this nerve
against the bone, leading to postoperative motor deficit manifested as
foot drop.
Question 3
What is the specific pharmacological reversal agent used to neutralize
the anticoagulant effects of heparin sodium during vascular surgical
procedures?
• A. Vitamin K
• B. Protamine sulfate
• C. Fresh frozen plasma
• D. Aminocaproic acid
Correct Answer: B. Protamine sulfate
,Detailed Rationale: Protamine sulfate is a strongly basic polypeptide
that binds ionically to strongly acidic heparin, forming a stable salt
complex that neutralizes anticoagulant activity immediately upon
intravenous administration.
Question 4
How is a surgical wound categorized if an operative case involves
entering the upper or lower gastrointestinal tract or biliary tract under
elective conditions with minimal spillage?
• A. Class I: Clean
• B. Class II: Clean-Contaminated
• C. Class III: Contaminated
• D. Class IV: Dirty / Infected
Correct Answer: B. Class II: Clean-Contaminated
Detailed Rationale: Class II (clean-contaminated) wounds are operative
entries into the respiratory, alimentary, or genitourinary tracts under
controlled conditions without unusual contamination or major spillage,
carrying a slightly higher baseline infection risk than clean cases.
Question 5
What is the standard sequence for clamping and releasing vessels
during an open abdominal aortic aneurysm (AAA) repair to minimize
the risk of distal atheroembolization?
• A. Clamp distal vessels first, then proximal aorta; release proximal
clamp first, then distal clamps slowly.
, • B. Clamp proximal aorta first, then distal vessels; release distal
vessels first to flush debris, then release the proximal aortic clamp
slowly.
• C. Clamp all vessels simultaneously.
• D. Never use vascular clamps during AAA repair.
Correct Answer: B. Clamp proximal aorta first, then distal vessels;
release distal vessels first to flush debris, then release the proximal
aortic clamp slowly.
Detailed Rationale: Clamping the proximal aorta first prevents
dislodging debris into the renal and visceral arteries. When unclamping,
releasing the distal vessels (iliacs) briefly allows stagnant blood and
loose atheromatous debris to flush retrogradely or distally before fully
restoring proximal flow.
Question 6
Which specialized neurosurgical suction instrument features a thumb-
control vent and a smooth, angled metal tube designed to clear blood
and cerebrospinal fluid without damaging delicate neural tissue?
• A. Poole suction tip
• B. Yankauer suction tip
• C. Frazier suction tip
• D. Baron suction tube
Correct Answer: C. Frazier suction tip
Detailed Rationale: The Frazier suction cannula is a fine, angled metal
tube equipped with a thumb hole (vent) that allows the surgeon to
