Question 1

Which pH range is considered optimal for wound healing and proteolytic enzyme activity in a healing wound bed?

Accepted Answer

pH 5.5–6.5

Answer

A slightly acidic wound pH of 5.5–6.5 supports optimal healing by promoting oxygen release and inhibiting bacterial growth.

Question 2

A diabetic foot ulcer has a yellow fibrinous slough covering 80% of the wound bed. Which debridement method is SAFEST in a patient with peripheral arterial disease (ABI 0.5)?

Accepted Answer

Autolytic debridement with hydrogel

Answer

In patients with severe PAD, autolytic debridement is the safest as it is non-traumatic and does not risk further ischemic tissue damage.

Question 3

What is the PRIMARY purpose of wound irrigation during wound bed preparation?

Accepted Answer

To remove surface bacteria, debris, and loose necrotic tissue

Answer

Wound irrigation mechanically removes bacteria, debris, and loose necrotic material to reduce bioburden and prepare the wound bed.

Question 4

A chronic venous leg ulcer has copious exudate. Which dressing is MOST appropriate to manage excess moisture while maintaining a moist healing environment?

Accepted Answer

Foam dressing with high absorbency

Answer

High-absorbency foam dressings are ideal for highly exudating wounds as they absorb excess fluid while maintaining adequate moisture balance.

Question 5

Which enzyme is the PRIMARY target of collagenase-based enzymatic debriding agents used in wound care?

Accepted Answer

Type I and Type II collagen in necrotic tissue

Answer

Collagenase enzymatic agents specifically cleave denatured collagen (Types I and II) in necrotic slough, selectively debriding non-viable tissue.
