Question 1

The posterior tibial artery can be palpated most reliably at which anatomical location?

Accepted Answer

Posterior to the medial malleolus

Answer

The posterior tibial artery runs posterior and inferior to the medial malleolus, making it the standard site for pedal pulse assessment.

Question 2

Which anatomical structure forms the medial boundary of the femoral triangle?

Accepted Answer

Adductor longus muscle

Answer

The femoral triangle is bounded medially by the adductor longus, laterally by the sartorius, and superiorly by the inguinal ligament.

Question 3

Hydrostatic pressure in the lower extremity venous system is greatest in which posture?

Accepted Answer

Standing upright

Answer

In the standing position, venous hydrostatic pressure in the ankle veins equals the vertical height of blood from the heart to the foot, typically 80–100 mmHg.

Question 4

The saphenofemoral junction (SFJ) is typically located how far below the inguinal ligament?

Accepted Answer

3–4 cm

Answer

The great saphenous vein joins the common femoral vein at the SFJ, which lies approximately 3–4 cm below the inguinal ligament in most adults.

Question 5

Which vessel is the primary collateral pathway when the subclavian artery is occluded proximal to the vertebral artery origin?

Accepted Answer

Vertebral artery (via subclavian steal)

Answer

Subclavian steal syndrome occurs when the vertebral artery reverses flow to supply the ischemic arm, stealing blood from the posterior circulation.
