Question 1

A patient receiving negative pressure wound therapy (NPWT) develops sudden bright red blood in the drainage tubing. The FIRST action the wound care clinician should take is:

Accepted Answer

Discontinue NPWT and apply direct pressure

Answer

Sudden bright red blood signals active hemorrhage; NPWT must be stopped immediately and direct pressure applied to control bleeding before any other action.

Question 2

Which statement BEST describes the role of matrix metalloproteinases (MMPs) in chronic wounds?

Accepted Answer

MMPs are elevated and cause excessive degradation of the extracellular matrix, impairing healing

Answer

Chronic wounds have elevated MMP levels that degrade growth factors, collagen, and fibronectin, creating a proteolytic environment that impedes healing.

Question 3

For a venous leg ulcer, the MINIMUM ankle-brachial index (ABI) generally required before applying full compression (40 mmHg) is:

Accepted Answer

0.8

Answer

An ABI of 0.8 or above is the accepted threshold for safe application of full therapeutic compression therapy for venous ulcers.

Question 4

A wound with 100% black eschar on the heel of an immobile patient should initially be treated by:

Accepted Answer

Leaving it intact and monitoring for signs of infection

Answer

Stable, dry, non-infected heel eschar should be left intact per NPUAP/EPUAP guidelines, as it serves as the body's natural cover over an ischemic area.

Question 5

Which wound bed preparation concept is captured by the acronym TIME?

Accepted Answer

Tissue, Infection/Inflammation, Moisture, Edge
