Question 1

Which classification system is most widely used to grade diabetic foot ulcers in clinical podiatric practice?

Accepted Answer

Wagner Classification System

Answer

The Wagner Classification System (grades 0–5) is the most widely adopted grading tool for diabetic foot ulcers, assessing depth and presence of infection or gangrene.

Question 2

A patient with diabetes presents with a painless plantar ulcer and absent Achilles reflex. Which underlying condition is most likely contributing to the ulcer formation?

Accepted Answer

Diabetic peripheral neuropathy

Answer

Absent deep tendon reflexes combined with a painless ulcer are hallmark signs of diabetic peripheral neuropathy, which impairs protective sensation and leads to pressure-related ulceration.

Question 3

When performing the monofilament test (Semmes-Weinstein) for diabetic neuropathy screening, which filament size indicates loss of protective sensation?

Accepted Answer

10 g (5.07 monofilament)

Answer

Inability to perceive the 10-gram (5.07 Semmes-Weinstein) monofilament at any plantar site indicates loss of protective sensation in diabetic patients.

Question 4

In managing a Grade 2 Wagner diabetic foot ulcer with suspected deep-tissue infection, which imaging modality is most sensitive for detecting osteomyelitis?

Accepted Answer

MRI

Answer

MRI is the most sensitive and specific imaging modality for detecting osteomyelitis in the diabetic foot, allowing visualization of bone marrow edema and soft tissue involvement.

Question 5

Which ankle-brachial index (ABI) value range is considered indicative of severe peripheral arterial disease requiring vascular surgery referral?

Accepted Answer

Below 0.4

Answer

An ABI below 0.4 indicates critical limb ischemia and severe peripheral arterial disease, warranting urgent vascular surgery consultation to preserve limb viability.
