The negative pressure wound therapy device alarms for an air leak. What should the nurse do first?

A. Increase the suction pressure to maximum
B. Remove the dressing and apply wet gauze
C. Check the dressing seal and tubing connections for leaks
D. Turn off the device and leave it off

Show answer and rationale

Correct answer: C

Most alarms come from breaks in the seal or tubing. Restoring the seal quickly maintains therapy. If therapy is interrupted for an extended time (often about 2 hours), the dressing is replaced per policy.
