A nurse is assisting with a diagnostic paracentesis for a client with suspected peritonitis. The nurse understands that this procedure involves:

Choice A reason:

An electrocardiogram (ECG) is used to assess the electrical activity of the heart and is not specific to diagnosing peritonitis.

Choice B reason:

A complete blood count (CBC) may reveal elevated white blood cell count and inflammatory markers, but it alone cannot confirm the diagnosis of peritonitis.

Choice C reason:

A chest X-ray may be performed to rule out other conditions, but it is not the primary diagnostic test for peritonitis.

Choice D reason:

An abdominal computed tomography (CT) scan is a valuable diagnostic tool for identifying signs of inflammation and infection in the peritoneal cavity, aiding in the confirmation of peritonitis.

Choice A reason:

Administering pain medication is important for the client's comfort, but it is not the highest priority in managing sepsis, a life-threatening complication 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 broad-spectrum antibiotic therapy is more critical in managing sepsis.

Choice C reason:

Initiating broad-spectrum antibiotic therapy is the highest priority in managing sepsis. Prompt administration of antibiotics is crucial to treat the bacterial infection and prevent its spread.

Choice D reason:

Providing deep breathing exercises is important for preventing respiratory complications, but it is not the highest priority compared to addressing sepsis with antibiotics.
