Question 1

Which classification system specifically grades diabetic foot ulcers based on depth, infection, and ischemia?

Accepted Answer

University of Texas Classification

Answer

The University of Texas Classification grades ulcers on both wound depth (0-III) and the presence of infection and/or ischemia, providing better prognostic value than Wagner alone.

Question 2

A diabetic patient presents with a warm, swollen, erythematous foot without an open wound. X-ray shows joint disorganization. What is the most likely diagnosis?

Accepted Answer

Charcot neuroarthropathy

Answer

Acute Charcot neuroarthropathy classically presents as a warm, swollen, erythematous foot in a neuropathic diabetic patient, often mistaken for infection.

Question 3

Which offloading device is considered the gold standard for treating plantar diabetic foot ulcers?

Accepted Answer

Total contact cast

Answer

The total contact cast (TCC) is the gold standard for offloading plantar diabetic foot ulcers because it cannot be removed by the patient and distributes plantar pressure evenly.

Question 4

In the Eichenholtz classification of Charcot neuroarthropathy, Stage I (development) is characterized by which finding?

Accepted Answer

Fragmentation, debris, and joint dislocation

Answer

Eichenholtz Stage I (development) is characterized by periarticular fragmentation, debris formation, joint subluxation, and dislocation on radiograph.

Question 5

Which ankle-brachial index (ABI) value range indicates severe peripheral arterial disease requiring urgent vascular evaluation?

Accepted Answer

Less than 0.40

Answer

An ABI less than 0.40 indicates critical limb ischemia, signifying severe PAD with high risk of limb loss if not urgently revascularized.
