A client with a history of kidney stones is prescribed potassium citrate. Which statement by the client indicates understanding of the medication's purpose?

A. This statement is not correct. If a client has calcium oxalate stones, they should limit foods high in oxalate, such as spinach and nuts, to reduce the risk of stone formation.

B. This is the correct answer. Calcium oxalate stones are the most common type of kidney stone. Reducing dietary calcium intake can help prevent the formation of calcium oxalate stones. However, it is important to note that not all clients with kidney stones should reduce their calcium intake, as calcium is essential for bone health and other bodily functions.

C. Avoiding foods high in purines is more relevant to the prevention of uric acid stones, not calcium oxalate stones.

D. While reducing sodium and processed foods can be beneficial for overall health, it is not a specific dietary modification for preventing calcium oxalate stones.

A. This is the correct answer. After percutaneous nephrolithotomy (PCNL), the client may experience urinary retention due to swelling and irritation around the bladder or urethra from the procedure. The nurse should monitor the client for signs of urinary retention, such as difficulty urinating or a distended bladder, and take appropriate measures to relieve the obstruction.

B. Hyperkalemia is not directly related to PCNL. It may occur in certain medical conditions but is not a common complication of this procedure.

C. Hypoglycemia is not related to PCNL. It is a condition related to low blood sugar levels and is not a typical complication of kidney stone removal.

D. Hypertension is not directly related to PCNL. While some clients with hypertension may be at increased risk for kidney stones, hypertension is not a common complication of PCNL itself.
