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:

Increased urine output is not a concerning finding in this context and may indicate adequate fluid resuscitation.

Choice B reason:

Abdominal distension and firmness are concerning findings and may indicate the development of abdominal compartment syndrome, a serious complication of peritonitis.

Choice C reason:

Normal respiratory rate is a positive finding, but it does not directly relate to the development of abdominal compartment syndrome.

Choice D reason:

Mild incisional pain is expected after surgery, but it does not indicate the development of abdominal compartment syndrome.

Choice A reason:

Administering pain medication is important for the client's comfort, but it is not the highest priority in the management of peritonitis. Addressing the underlying infection with antibiotics takes precedence.

Choice B reason:

Monitoring vital signs is essential for assessing the client's condition, but initiating antibiotic therapy is more critical to address the underlying infection.

Choice C reason:

Initiating intravenous (IV) antibiotic therapy is the highest priority in the management of peritonitis. Prompt administration of antibiotics is essential to treat the bacterial infection and prevent its spread.

Choice D reason:

Encouraging deep breathing and coughing exercises is beneficial for preventing respiratory complications, but it is not the highest priority compared to addressing the infection with antibiotics.
