Final answer:
The most effective nursing action to manage abdominal discomfort in a postoperative patient with the absence of bowel sounds is encouraging frequent ambulation.
Step-by-step explanation:
The most effective nursing action to help manage abdominal discomfort in a postoperative patient with absence of bowel sounds is encouraging frequent ambulation.
Ambulation helps stimulate the digestive system, which can promote bowel movement and relieve discomfort. Additionally, it helps prevent complications such as constipation and respiratory complications.
Administering PRN pain medications may help with pain relief, but it may not directly address the underlying issue of absent bowel sounds. Furthermore, ensuring adequate fluids by mouth and providing sufficient fiber in the diet can play a role in managing overall gastrointestinal health, but they may not be the most effective immediate nursing action for relieving discomfort.
