Question 1

What ankle-brachial index (ABI) value is diagnostic of peripheral arterial disease?

Accepted Answer

ABI < 0.9

Answer

An ABI below 0.9 indicates peripheral arterial disease, with values below 0.4 suggesting critical limb ischemia.

Question 2

Which symptom is the classic hallmark of intermittent claudication?

Accepted Answer

Calf cramping with walking that resolves with rest

Answer

Intermittent claudication is reproducible muscle pain (often calf) that occurs with walking and is relieved by rest due to inadequate arterial supply during exercise.

Question 3

Which finding is most indicative of critical limb ischemia?

Accepted Answer

Rest pain in the foot and ischemic ulceration or gangrene

Answer

Critical limb ischemia is defined by ischemic rest pain and/or tissue loss (ulceration or gangrene) due to severely reduced arterial perfusion.

Question 4

What is Charcot-Marie-Tooth (CMT) disease?

Accepted Answer

An inherited peripheral neuropathy causing distal muscle weakness and sensory loss

Answer

CMT is the most common inherited peripheral neuropathy, causing progressive distal weakness, sensory loss, and foot deformities such as pes cavus.

Question 5

Which nerve entrapment syndrome causes burning pain radiating to the heel and arch from behind the medial malleolus?

Accepted Answer

Tarsal tunnel syndrome

Answer

Tarsal tunnel syndrome results from compression of the posterior tibial nerve within the tarsal tunnel behind the medial malleolus, causing burning and tingling in the plantar foot.
