Question 5 of 5
The nurse must irrigate a gaping abdominal incision with sterile normal saline, using a piston syringe. How should the nurse proceed?
Correct Answer: A
Rationale:
To wash away tissue debris and drainage effectively, the nurse should irrigate the wound until the solution becomes clear or all of the solution has been used. After the irrigation, the nurse should dry the area around the wound; moistening it promotes microorganism growth and skin irritation. When the area is dry, the nurse should apply a sterile dressing, rather than a wet-to-dry dressing. The nurse always should instill the irrigating solution gently; rapid or forceful instillation can damage tissues.
