Which of the following is the most common substance found on analysis of a renal stone?

A. Increased urinary output: Phenazopyridine (Pyridium) does not directly impact urinary output. Its primary function is to provide relief from urinary pain, burning, and discomfort associated with urinary tract infections (UTIs) or other urinary conditions. It does not affect the amount of urine a person produces.

B. Decreased WBC's: Phenazopyridine does not directly influence white blood cell count (WBCs). WBC count is an indicator of the body's immune response and is typically used to assess the presence of infection. Phenazopyridine provides symptomatic relief but does not affect the underlying infection or the body's immune response to it.

C. Increased uric acid: Phenazopyridine does not affect uric acid levels. Uric acid is a waste product that is excreted by the kidneys. Elevated uric acid levels can be associated with conditions like gout, but Phenazopyridine does not have any direct impact on these levels.

D. Decreased bladder pain/spasms: Phenazopyridine is intended to relieve symptoms such as bladder pain, spasms, burning sensation, and discomfort experienced during urination. Therefore, the effectiveness of Phenazopyridine is indicated by a reduction in these symptoms. If the patient reports a decrease in bladder pain and spasms, it suggests that the medication is working to alleviate the discomfort associated with urinary tract issues.

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.
