A nurse is caring for a client who has heavy drainage from a moist red wound that is bleeding.
Which of the following types of dressings should the nurse select to help promote hemostasis?

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.

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.
