At 0930, the nurse in the medical-surgical unit is caring for a 61-year-old male with a negative-pressure wound therapy (NPWT) system on a diabetic foot ulcer. The NPWT unit displays a 'blockage/obstruction' alarm. The nurse notes that the tubing is free of kinks, but there is a stagnant, thick column of wound exudate pooled in the distal suction line, and the canister is only 10% full.

What is the nurse's safest first action?

  1. Disconnect the tubing from the canister and flush the line with 20 mL of sterile normal saline toward the wound.
  2. Gently massage or roll the tubing to break up the coagulated fluid column and check that all clamps are open.
  3. Lower the NPWT unit below the level of the client's foot to let gravity drain the pooled exudate.
  4. Increase the suction setting to -150 mm Hg to force the obstruction into the canister.
