Which of the following is a form of mechanical debridement that the nurse should expect the client to receive?

applying hydrocolloids to the wound bed.

placing a transparent dressing over the pressure injury.

pulsating lavage.

using a topical enzyme solution in the wound bed.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Hydrocolloids are not a form of mechanical debridement. They are dressings that promote autolytic debridement by maintaining a moist wound environment.

Choice B rationale:

Transparent dressings are not a form of mechanical debridement. They are used to protect the wound and allow for visual inspection.

Choice C rationale:

Pulsating lavage is a form of mechanical debridement. It involves using a pressurized, pulsed solution to remove necrotic tissue from the wound bed.

Choice D rationale:

Topical enzyme solutions are not a form of mechanical debridement. They are a form of chemical debridement that breaks down necrotic tissue.

Correct Answer is D

Explanation

Choice A rationale:

Sharp debridement involves the use of a sharp instrument or heat to remove dead tissue, which is not achieved with a hydrocolloid dressing.

Choice B rationale:

Chemical debridement involves the use of chemicals to remove dead tissue, which is not the function of a hydrocolloid dressing.

Choice C rationale:

Enzymatic debridement involves the use of enzymes to soften and remove dead tissue, which is not the function of a hydrocolloid dressing.

Choice D rationale:

Autolytic debridement uses the body’s own enzymes and moisture to soften and remove dead tissue. A hydrocolloid dressing helps maintain a moist wound environment, promoting autolytic debridement.

A. From the left to the right across the wound. B. From the outer abdomen toward the wound. C. In a circular motion around the wound, circling to the outside. D. Directly over the wound.

Correct Answer is C

Explanation

Choice A rationale:

Cleaning from left to right across the wound can introduce bacteria from the surrounding skin into the wound, which can lead to infection.

Choice B rationale:

Cleaning from the outer abdomen toward the wound can also introduce bacteria from the surrounding skin into the wound.

Choice C rationale:

Cleaning in a circular motion around the wound, circling to the outside, helps to move bacteria away from the wound and reduce the risk of infection.

Choice D rationale:

Cleaning directly over the wound can disrupt the healing process and potentially introduce bacteria into the wound.
