Diabetic Wound Care Exam Prep Exam Questions & Answers 2026 (21–30)

Question 1

A clinician debrides a plantar diabetic foot ulcer but fails to implement an offloading plan. What is the likely clinical outcome?

TheoryPractice · Accepted Answer

Recalcitrant healing. Without offloading to relieve mechanical stress, the wound stimulus persists, leading to recalcitrant healing.

Question 2

Which physiological process is the primary hallmark of the remodeling phase of wound healing?

TheoryPractice · Accepted Answer

Collagen Type I synthesis. Remodeling replaces immature Type III collagen with Type I collagen to increase wound tensile strength.

Question 3

A diabetic patient with a non-healing foot ulcer has an Ankle-Brachial Index (ABI) of 1.4. Which test is indicated next?

TheoryPractice · Accepted Answer

Toe-Brachial Index (TBI). An ABI > 1.4 indicates calcified arteries; TBI is reliable as toe vessels rarely calcify.

Question 4

A patient demonstrates loss of vibratory sensation and proprioception. Which clinical risk is primarily associated with this large-fiber deficit?

TheoryPractice · Accepted Answer

Unperceived repetitive trauma. Large-fiber neuropathy causes loss of protective sensation, leading to unperceived repetitive trauma and subsequent ulceration during ambulation.

Question 5

A diabetic patient presents with a red, hot, swollen foot but no open wound or systemic fever. What is the priority intervention?

TheoryPractice · Accepted Answer

Strict total non-weight bearing. These signs suggest acute Charcot neuroarthropathy. Immediate total non-weight bearing prevents bone collapse and permanent foot deformity.

Question 6

Which growth factor is critically deficient in diabetic wounds, directly leading to impaired angiogenesis and capillary sprouting?

TheoryPractice · Accepted Answer

VEGF. VEGF drives angiogenesis. In diabetic wounds, blunted VEGF expression leads to poor capillary growth and insufficient granulation tissue.

Question 7

How does the accumulation of advanced glycation end-products (AGEs) structurally alter the skin in patients with diabetes?

TheoryPractice · Accepted Answer

Decreases collagen turnover. AGEs cross-link collagen, making it resistant to enzymatic degradation. This reduces collagen turnover, causing stiff, non-compliant skin.

Question 8

A patient perceives a sharp pinprick but cannot feel the 10g Semmes-Weinstein monofilament. What is the correct interpretation?

TheoryPractice · Accepted Answer

Loss of protective sensation. Inability to feel the 10g monofilament indicates loss of protective sensation, reflecting large-fiber dysfunction.

Question 9

What cellular dysfunction primarily drives the transition of a diabetic foot ulcer into a chronic, non-healing state?

TheoryPractice · Accepted Answer

Persistent pro-inflammatory macrophage phenotype. Persistent pro-inflammatory M1 macrophages prevent transition to the proliferative repair phase.

Question 10

A diabetic patient has palpable pulses, normal ABI, but a non-healing ulcer and atrophy. Which pathology is indicated?

TheoryPractice · Accepted Answer

Microvascular disease (microangiopathy). Atrophic skin and poor healing with normal macrovascular exams suggest capillary-level microangiopathy.
