A provider orders a diagnostic test for a client with a urinary tract infection. The test will determine the strain of bacteria causing the infection and determine the antibiotic that will treat the infection. The nurse knows this test is called which of the following?

A. "Pyelonephritis increases a person's risk for kidney damage." - Pyelonephritis is a bacterial infection of the renal parenchyma and renal pelvis, typically caused by the ascent of bacteria from the lower urinary tract into the kidneys. If left untreated, it can lead to kidney damage, including scarring of the renal tissue and impaired kidney function.

B. "Pyelonephritis is an infection of the lower urinary tract." - This statement is incorrect. Pyelonephritis specifically involves the upper urinary tract, affecting the kidneys. In contrast, infections of the lower urinary tract (such as cystitis) affect the bladder and urethra.

C. "Pyelonephritis often causes no symptoms in affected clients." - This statement is incorrect. Pyelonephritis typically presents with symptoms such as fever, chills, flank pain, painful urination (dysuria), and frequent urination. Clients with pyelonephritis usually experience noticeable symptoms.

D. "Pyelonephritis is most often caused by Staphylococcus saprophyticus." - This statement is incorrect. While Staphylococcus saprophyticus is a common cause of urinary tract infections, pyelonephritis is more commonly caused by gram-negative bacteria, such as Escherichia coli, which often ascend from the lower urinary tract into the kidneys.

A. Manage bladder irrigation following the procedure. - Bladder irrigation is not typically performed after ESWL. It may be used in other urological procedures, but it is not a standard post-procedural care for ESWL.

B. Administer a bolus of 750 mL normal saline following the procedure. - While maintaining hydration is important, there is no specific requirement for a bolus of normal saline after ESWL. Hydration is usually encouraged, but the amount and method of administration are determined based on the client's overall fluid status and medical condition.

C. Strain the client's urine following the procedure.
After extracorporeal shock wave lithotripsy (ESWL), it is essential to strain the client's urine to collect any stone fragments. Straining allows healthcare providers to analyze the composition of the stones, ensuring that all fragments have been passed. This information helps in assessing the effectiveness of the procedure and guides further management.

D. Insert a urinary catheter for 24 to 48 hours after the procedure. - Inserting a urinary catheter is not a routine post-procedural measure after ESWL. Catheterization might be necessary in certain situations or for specific medical reasons, but it is not a standard practice after ESWL for all clients.
