Question 1

Which structure passes through the femoral triangle and is at risk during inguinal hernia repair?

Accepted Answer

Femoral nerve

Answer

The femoral nerve lies in the femoral triangle lateral to the femoral artery and must be avoided during inguinal hernia repair to prevent motor deficit of the quadriceps.

Question 2

During a right colectomy, which structure lies in close proximity to the ileocolic vessels and must be identified to avoid injury?

Accepted Answer

Right ureter

Answer

The right ureter runs retroperitoneally along the psoas muscle near the ileocolic vessels and must be identified before ligation during right colectomy.

Question 3

The saphenous vein joins which vessel in the femoral triangle?

Accepted Answer

Femoral vein

Answer

The great saphenous vein drains into the femoral vein at the saphenofemoral junction, which is ligated during vein stripping procedures.

Question 4

Which fascial layer of the neck must be incised during central venous catheter insertion via the internal jugular approach?

Accepted Answer

Investing layer of deep cervical fascia

Answer

The investing layer of the deep cervical fascia encloses the sternocleidomastoid muscle and must be penetrated to access the internal jugular vein.

Question 5

In which anatomical space does a retroperitoneal hematoma develop after injury to the aorta or inferior vena cava?

Accepted Answer

Retroperitoneal space posterior to parietal peritoneum

Answer

Retroperitoneal hematomas accumulate in the space posterior to the parietal peritoneum, where the aorta, IVC, and their branches reside.
