What is the final step in applying the NPWT system according to the described procedure?

• A. Insert end of tubing and secure
• B. Start the suction immediately
• C. Check for leaks after applying additional drape
• D. Remove the drape and sponge after 5 minutes

Answer: (A)

In NPWT, the goal is a sealed, continuous negative-pressure system so the pump can maintain consistent suction without losing pressure. The final step is to insert the end of the tubing and secure it, creating a solid connection between the dressing and the suction unit. This ensures air can’t sneak in and compromise the therapy. After the tubing is firmly connected and the seal is checked, you would then proceed with turning on suction. Starting suction before this secure connection or removing the drape and sponge isn’t appropriate, and while checking for leaks is important, it’s part of confirming the seal rather than the final step.
