Question 1

Which pressure redistribution device is considered the gold standard for prevention of pressure injuries in high-risk patients?

Accepted Answer

Active (alternating pressure) support surface

Answer

Active alternating-pressure support surfaces continuously redistribute pressure by cyclically inflating and deflating air cells, reducing sustained tissue loading in high-risk patients.

Question 2

When caring for a patient with a diabetic foot ulcer (DFU), Charcot neuroarthropathy should be suspected when the foot presents with:

Accepted Answer

Warmth, erythema, and swelling in a neuropathic patient without open wound

Answer

Charcot neuroarthropathy classically presents with warmth, swelling, and erythema of the foot in a patient with peripheral neuropathy, often mistaken for cellulitis.

Question 3

The minimum recommended irrigation pressure for effective wound cleansing is:

Accepted Answer

4–15 psi

Answer

An irrigation pressure of 4–15 psi is sufficient to remove surface debris and bacteria without traumatizing wound tissue.

Question 4

A wound that has been present for more than 30 days without measurable progress toward closure is classified as:

Accepted Answer

A chronic wound

Answer

A wound that fails to progress through the normal healing phases within approximately 30 days is classified as a chronic wound, indicating an underlying impediment to healing.

Question 5

Platelet-rich plasma (PRP) therapy promotes wound healing primarily through:

Accepted Answer

Delivery of concentrated growth factors to the wound site
