Answer to Question 2
D
The primary purpose of wet-to-dry dressings is to mechanically debride a wound. The moistened contact layer of the dressing (primary dressing) increases the absorptive ability of the dressing to collect exudate and wound debris. As the dressing dries, it adheres to the wound and debrides the wound of tissue when the dressing is removed. The moistened gauze must be covered with a secondary dressing layer that is dry. It is incorrect technique and a common error by some clinicians to moisten the dried gauze before removing it. This defeats the purpose of using this type of dressing and reduces the amount of debris that the dressing will remove. Open or fluff the woven gauze that will be placed directly against the wound bed. Moisten the packing material with a noncytotoxic solution such as normal saline. Never use cytotoxic solutions.
