When the patient complains that he feels he is getting worse because of the increased swelling at his wound site on his leg, the nurse's most helpful response would be that swelling indicates that:

Choice A rationale:

Decreased serum calcium does not directly contribute to pressure injury development.

Choice B rationale:

Decreased circulation can lead to tissue ischemia and necrosis, increasing the risk of pressure injury.

Choice C rationale:

Increased collagen is beneficial for wound healing and does not increase the risk of pressure injury.

Choice D rationale:

Increased muscle mass can actually provide more padding over bony prominences, reducing the risk of pressure injury.

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.
