Final answer:
Appropriate actions for cleaning and dressing a pressure ulcer include cleaning with saline solution, removing loose debris with sterile forceps, and using a transparent film or other moisture-retentive dressing.
Step-by-step explanation:
When cleaning and dressing a pressure ulcer, appropriate actions for the nurse to take include using a gentle saline solution for wound cleaning, sterile forceps to remove any loose debris, and applying a protective dressing that maintains a moist environment, such as a transparent film dressing or other appropriate moisture-retentive dressings. A thick layer of petroleum jelly is not generally recommended, as it may impede the absorption of exudate. Covering the wound with a dry gauze dressing may be less beneficial in certain stages of pressure ulcer healing and may adhere to the wound bed, causing damage upon removal.
