The nurse is performing an admission assessment for a client with pyelonephritis who has urgency and burning while urinating. Which finding indicates an expected response when the nurse percusses the costovertebral angle?

A) Sharp, severe pain:
Percussion of the costovertebral angle (CVA) elicits sharp, severe pain in a client with pyelonephritis. This response indicates inflammation of the kidney and surrounding tissues, which is typical in pyelonephritis.

B) Audible thud without pain:
An audible thud without pain is a normal finding when percussing the CVA and would not be expected in a client with pyelonephritis.

C) Rigidity and firmness:
Rigidity and firmness may be related to muscle guarding or abdominal assessment findings, but they are not specific to CVA percussion and pyelonephritis.

D) Rebound tenderness:
Rebound tenderness is a sign of peritoneal irritation and is assessed by pressing on the abdomen and quickly releasing. It is not the typical finding associated with CVA percussion in pyelonephritis.

A) Notify the healthcare provider of the rebound tenderness:
Rebound tenderness, also known as Blumberg's sign, is a clinical sign that suggests peritoneal irritation, which can be indicative of underlying pathology such as peritonitis. Reporting rebound tenderness to the healthcare provider is crucial for further evaluation and management of the client's condition.

B) Obtain a prescription to catheterize the client's bladder:
While urinary retention can present with lower abdominal discomfort, the scenario described does not specifically suggest urinary retention. Catheterization should be considered based on additional assessments and indications related to urinary symptoms, not solely based on the client's report of pain upon release of abdominal pressure.

C) Offer to administer a laxative prescribed for PRN use:
Administering a laxative would not be appropriate based solely on the client's report of pain upon release of abdominal pressure. Laxatives are indicated for constipation, which may cause abdominal discomfort, but they would not address rebound tenderness or the underlying cause of the client's pain.

D) Instruct the client in distraction and relaxation techniques:
While distraction and relaxation techniques can be helpful for managing pain, they would not address the underlying cause of rebound tenderness. Reporting rebound tenderness to the healthcare provider is necessary for further evaluation and appropriate management.
