A nurse is assisting with the care of a client who is postoperative and has a closed-wound drainage system in place. Which of the following actions should the nurse take?
Replace the drainage plug after releasing hand pressure on the device.
Empty the reservoir once per day.
Fully recollapse the reservoir after emptying it.
Irrigate the tubing with sterile normal saline solution at least once every 8 hr.
The Correct Answer is C
A. Replace the drainage plug after releasing hand pressure on the device:
Doing this allows air into the reservoir, preventing the vacuum effect. Plug should be replaced while still compressed.
B. Empty the reservoir once per day:
Reservoirs should be emptied at least every shift or when half full, not just once a day.
C. Fully recollapse the reservoir after emptying it:
This restores negative pressure, allowing continuous drainage and wound healing.
D. Irrigate the tubing with sterile normal saline solution at least once every 8 hr:
Irrigating the tubing is not standard care for closed-wound drains and can introduce infection.

Correct Answer is A
Explanation
A. Cleanse the wound with sterile saline:
This removes surface contaminants, ensuring the specimen reflects organisms within the wound, not contaminants from the skin.
B. Don sterile gloves:
While sterile technique is important, cleansing the wound must occur before donning sterile gloves to prevent contaminating the site.
C. Swab the wound bed with a sterile cotton-tipped swab:
This is done after cleansing the wound to collect an accurate sample.
D. Place the collection tube in a specimen bag:
This is the final step after the specimen is collected.
