NCWO Wound Assessment 3

Question 1

The ankle-brachial index (ABI) value that indicates significant arterial insufficiency and requires referral is:

Accepted Answer

Less than 0.5

Answer

An ABI below 0.5 indicates severe arterial insufficiency and warrants urgent vascular surgery referral before applying compression therapy.

Question 2

Which of the following is the most reliable method to confirm biofilm presence in a chronic wound?

Accepted Answer

Wound biopsy and microscopy

Answer

Biofilm can only be definitively confirmed through wound biopsy and microscopic analysis, as it is not reliably detected by swab culture or visual inspection alone.

Question 3

Wound edge epibole (rolled or thickened edges) indicates:

Accepted Answer

Inward rolling of the epidermis impeding wound closure

Answer

Epibole occurs when the epidermis rolls inward and downward at the wound edge, preventing epithelial cells from migrating across the wound bed.

Question 4

When measuring wound depth, the WOC nurse should use a:

Accepted Answer

Sterile cotton-tipped applicator inserted perpendicular to the wound bed

Answer

A sterile cotton-tipped applicator inserted perpendicular to the wound bed and measured against a ruler is the standard bedside technique for wound depth measurement.

Question 5

Venous leg ulcers (VLUs) are most commonly located:

Accepted Answer

In the gaiter zone (medial lower leg above the medial malleolus)

Answer

VLUs characteristically occur in the gaiter zone of the medial lower leg, from the ankle to mid-calf, due to sustained venous hypertension in that region.
