A 28-year-old male is a patient at your clinic.
He states that he had a minor accident with his motorcycle 5 days ago.
He sustained several scrapes and wounds.
The wound on his calf has a pinkish-red center area that looks bumpy.
This indicates that the wound is:

D.

Choice A rationale:

A BMI of 20 is within the normal range (18.5-24.9), so it does not increase the risk of pressure injuries.

Choice B rationale:

Peripheral neuropathy can lead to decreased sensation, increasing the risk of pressure injuries as the person may not feel discomfort from prolonged pressure.

Choice C rationale:

Immobility is a major risk factor for pressure injuries as it increases the duration of pressure on certain areas of the body.

Choice D rationale:

Hypoperfusion, or reduced blood flow, can lead to tissue damage and increase the risk of pressure injuries.

Choice E rationale:

A prealbumin level of 16 mg/dL is within the normal range (15-36 mg/dL), so it does not increase the risk of pressure injuries.

Choice A rationale:

Strengthening the wall of the wound is not the primary function of vacuum-assisted closure. The main function is to promote wound healing by applying negative pressure.

Choice B rationale:

Drawing the wound edges together by negative pressure is the correct answer. Vacuum-assisted closure, also known as negative pressure wound therapy, works by applying negative pressure to the wound, which helps to draw the edges of the wound together and promote healing.

Choice C rationale:

Making an air occlusive cover for the wound is not the primary function of vacuum-assisted closure. The main function is to promote wound healing by applying negative pressure.

Choice D rationale:

Interrupting the proliferation of bacteria in the wound is not the primary function of vacuum-assisted closure. The main function is to promote wound healing by applying negative pressure.
