A client with a history of appendectomy develops peritonitis. The nurse anticipates which diagnostic test to confirm the diagnosis?

Chest X-ray

Electrocardiogram (ECG)

Abdominal ultrasound

Complete blood count (CBC)

Answer and Explanation

The Correct Answer is C

Choice A reason:

A chest X-ray is not the primary diagnostic test for peritonitis.

Choice B reason:

An ECG is used to assess cardiac function and is not specific to peritonitis.

Choice C reason:

An abdominal ultrasound is commonly used to diagnose peritonitis and can help visualize inflammation or fluid in the peritoneal cavity.

Choice D reason:

A CBC may show elevated white blood cell count, which is an indication of infection, but it is not a confirmatory test for peritonitis.

Correct Answer is C

Explanation

Choice A reason:

An electrocardiogram (ECG) is used to assess the electrical activity of the heart, not the abdomen.

Choice B reason:

An abdominal X-ray provides a basic overview of the abdomen but may not offer detailed images of the peritoneal organs and structures.

Choice C reason:

Magnetic resonance imaging (MRI) can provide high-resolution images of the abdominal organs and structures, including the peritoneum, making it a valuable diagnostic tool for suspected peritonitis.

Choice D reason:

Ultrasonography can provide images of the abdominal organs, but it may not offer the level of detail provided by MRI in assessing peritonitis.

A. Removal of fluid from the pleural cavity B. Removal of fluid from the pericardial sac C. Removal of fluid from the peritoneal cavity D. Removal of fluid from the spinal canal

Correct Answer is C

Explanation

Choice A reason:

Removal of fluid from the pleural cavity would be a thoracentesis, not a paracentesis.

Choice B reason:

Removal of fluid from the pericardial sac would be a pericardiocentesis, not a paracentesis.

Choice C reason:

A diagnostic paracentesis involves removing fluid from the peritoneal cavity to analyze for signs of infection and inflammation, which is important in diagnosing peritonitis.

Choice D reason:

Removal of fluid from the spinal canal would be a lumbar puncture, not a paracentesis.
