Because the patient with an abdominal dressing requires frequent dressing changes, the abdomen is beginning to show skin irritation from repeated tape removal.
The nurse would change the dressing procedure in order to use:

Choice A rationale:

Increased pallor of the surgical site is not a typical sign of wound dehiscence. It could indicate poor blood flow to the area, but it’s not directly related to dehiscence.

Choice B rationale:

Increased serosanguineous drainage from the wound is a common sign of wound dehiscence. This type of drainage is a mixture of blood and serum, and an increase could indicate that the wound edges are separating.

Choice C rationale:

Excessive gas is not a typical sign of wound dehiscence. It could be related to other postoperative complications, such as ileus or bowel obstruction, but not specifically to dehiscence.

Choice D rationale:

Complaint of constipation is not a typical sign of wound dehiscence. It could be related to other postoperative complications, such as side effects of pain medication or decreased mobility, but not specifically to dehiscence.

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.
