When changing dressings on a negative pressure system that is already in use, what should you do?

• A. Count the sponges as you remove
• B. Wash hands before changing
• C. Disinfect the tubing
• D. Apply new dressing

Answer: (A)

In negative pressure wound therapy dressing changes, counting the sponge pieces as you remove them is a crucial safety check. Foam dressings can shed fragments during removal, and if any sponge material is left behind, it becomes a foreign body that can cause infection or require additional procedures to retrieve.

By counting, you verify that all components are accounted for before applying the new dressing and resuming therapy. While hand hygiene and then applying a new dressing are part of the process, the act of counting directly prevents retained sponge fragments and ensures the wound remains clean and the therapy remains effective.
