Which type of debridement is a hydrocolloid dressing used for?

E.

Choice A rationale:

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

Choice B rationale:

Peripheral neuropathy can lead to a loss of sensation, which increases the risk of a pressure injury as the individual may not feel discomfort or recognize the need to reposition.

Choice C rationale:

Immobility is a major risk factor for pressure injuries as it increases pressure on certain areas of the body, reducing blood flow and leading to tissue damage.

Choice D rationale:

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

Choice E rationale:

A prealbumin level of 16 mg/dL is at the lower end of the normal range (15-36 mg/dL)2. Low prealbumin levels can indicate poor nutritional status, which is a risk factor for pressure injuries.

The correct answer is Choice D.

Choice A rationale: Leaving nonbleeding wounds open to air increases the risk of infection and delayed healing. Wounds need a moist environment to promote cell migration and collagen synthesis, essential for the initial inflammatory phase of healing.

Choice B rationale: Corticosteroids suppress the immune response and inflammation, which can delay wound healing. They inhibit leukocyte migration and fibroblast proliferation, which are crucial during the initial stage of the healing process.

Choice C rationale: Mechanical debridement is typically used for chronic wounds with necrotic tissue. In the initial stage of wound healing, it is not necessary and could damage newly formed tissue, delaying the healing process.

Choice D rationale: Oxygen therapy at 2L/min via nasal cannula enhances tissue oxygenation, promoting cellular activities such as collagen synthesis, angiogenesis, and leukocyte function, which are critical during the initial inflammatory phase of wound healing.
