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) Ask about recent abdominal trauma:
While abdominal trauma could potentially cause changes in the appearance of the umbilicus, such as bruising or swelling, it is not the most likely explanation for a depressed umbilicus below the surface of the abdomen. Additionally, without further evidence or symptoms suggestive of trauma, it may not be necessary to immediately inquire about recent abdominal trauma.

B) Observe the midline for scarring:
Observing the midline for scarring may be relevant if there are signs of previous surgical procedures or other abdominal interventions. However, the presence of a depressed umbilicus below the surface of the abdomen does not necessarily indicate scarring or previous surgery.

C) Document the normal finding:
A depressed umbilicus below the surface of the abdomen is a normal anatomical variation in some individuals, particularly those with a more slender build or a deeper abdominal cavity. It does not typically indicate pathology or require further intervention.

D) Palpate the area for masses:
Palpating the area for masses may be indicated if there are other signs or symptoms suggestive of abdominal pathology, but a depressed umbilicus alone is not typically an indication for palpation. In the absence of other concerning findings, it may be unnecessary and potentially uncomfortable for the client to perform palpation based solely on the observation of a depressed umbilicus.

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.
