Question 1

Which cell type is primarily responsible for wound contraction during the proliferative phase?

Accepted Answer

Myofibroblasts

Answer

Myofibroblasts, differentiated from fibroblasts under TGF-β stimulation, contain actin microfilaments that generate the contractile force to close wounds.

Question 2

A patient with a diabetic foot ulcer has a probe-to-bone test that is positive. What does this most likely indicate?

Accepted Answer

Osteomyelitis

Answer

A positive probe-to-bone test (ability to reach bone with a sterile probe) has a high positive predictive value for osteomyelitis in diabetic foot ulcers.

Question 3

Which negative pressure wound therapy (NPWT) setting is most commonly used for general wound management?

Accepted Answer

-125 mmHg continuous

Answer

The standard NPWT setting of -125 mmHg continuous has the most evidence supporting wound healing, perfusion improvement, and exudate management.

Question 4

In periwound skin assessment, maceration is best described as:

Accepted Answer

White, soft, waterlogged skin caused by excess moisture

Answer

Maceration occurs when periwound skin is excessively exposed to moisture, causing it to become white, soft, and fragile, increasing the risk of wound enlargement.

Question 5

Which condition is a contraindication to the use of negative pressure wound therapy?

Accepted Answer

Wound with exposed untreated osteomyelitis

Answer

Untreated osteomyelitis is a contraindication to NPWT because the therapy could spread infection further into bone and surrounding tissue without addressing the underlying infection.
