A client with suspected peritonitis is undergoing abdominal imaging. The nurse prepares the client for which diagnostic imaging modality that can provide detailed images of the peritoneal organs and structures?

Choice A reason:

Rebound tenderness refers to increased pain upon release of pressure during palpation and is not related to the finding of a rigid, board-like abdomen.

Choice B reason:

Paralytic ileus refers to a condition in which the intestines stop functioning, causing a lack of bowel sounds and distension, but it is not directly related to the rigid abdomen finding.

Choice C reason:

Abdominal compartment syndrome may cause abdominal distension and increased intra-abdominal pressure, but it does not necessarily result in a rigid, board-like abdomen.

Choice D reason:

The finding of a rigid, board-like abdomen upon palpation is known as guarding, which is a protective response of the abdominal muscles in peritonitis to minimize movement and protect the inflamed peritoneum.

Choice A reason:

Monitoring blood glucose levels is important for clients with various conditions, but it is not directly related to the management of acute kidney injury (AKI) in peritonitis.

Choice B reason:

Administering pain medication is essential for managing the client's pain and providing comfort during treatment, but it is not directly related to the management of acute kidney injury.

Choice C reason:

Encouraging fluid intake is important for clients with peritonitis, but the specific recommendation of 3 liters per day is not universally applicable and may vary based on individual client needs and medical status.

Choice D reason:

Maintaining fluid and electrolyte balance is crucial in managing acute kidney injury in peritonitis. The nurse should closely monitor the client's fluid intake, output, and electrolyte levels and collaborate with the healthcare team to adjust the fluid therapy as needed.
