Question 1

Which growth factor is primarily responsible for stimulating fibroblast proliferation and angiogenesis in diabetic foot wound healing?

Accepted Answer

Platelet-derived growth factor (PDGF)

Answer

PDGF is the primary growth factor approved (becaplermin/Regranex) for stimulating fibroblast proliferation and angiogenesis in diabetic neuropathic foot ulcers.

Question 2

A chronic wound with 100% yellow slough and no granulation tissue is best classified using the PUSH tool as having which tissue type score?

Accepted Answer

2

Answer

In the PUSH (Pressure Ulcer Scale for Healing) tool, slough tissue scores 2, while necrotic/eschar scores 3, granulation scores 1, and closed/resurfaced scores 0.

Question 3

When performing a wound culture on a diabetic foot ulcer, which technique yields the most clinically relevant microbiological data?

Accepted Answer

Quantitative tissue biopsy

Answer

Quantitative tissue biopsy is the gold standard for wound culture, as surface swabs commonly reflect surface colonizers rather than true tissue pathogens.

Question 4

A patient presents with a venous leg ulcer covered in fibrinous slough. Which debridement method is most appropriate if the patient cannot tolerate pain?

Accepted Answer

Autolytic debridement with a hydrogel

Answer

Autolytic debridement using moisture-retentive dressings like hydrogels is painless and well-tolerated, making it ideal for pain-sensitive patients.

Question 5

Which ankle-brachial index (ABI) range indicates moderate peripheral arterial disease (PAD) that may still permit cautious compression therapy?

Accepted Answer

ABI 0.5–0.79

Answer

An ABI of 0.5–0.79 indicates moderate PAD; reduced compression (e.g., 20–30 mmHg) may be used cautiously with close monitoring.
