Correct Answer is B

Explanation

Choice A rationale:

Refraining from touching the drainage spout with the hand is a correct practice. This helps to prevent contamination of the drain.

Choice B rationale:

Using one alcohol wipe to clean both the spout and the plug is incorrect. Each part should be cleaned with a separate alcohol wipe to prevent cross-contamination.

Choice C rationale:

Pointing the device away from oneself while opening it is a correct practice. This helps to prevent accidental exposure to the drainage fluid.

Choice D rationale:

Compressing the device in the hand before closing is a correct practice. This helps to maintain the suction in the drain.

A. applying hydrocolloids to the wound bed. B. placing a transparent dressing over the pressure injury. C. pulsating lavage. D. using a topical enzyme solution in the wound bed.

Correct Answer is C

Explanation

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.
