A client with a history of kidney stones is prescribed a thiazide diuretic. The nurse should monitor the client's laboratory values for which electrolyte imbalance?

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. Thiazide diuretics do not directly increase the excretion of uric acid. They are primarily used to reduce calcium excretion and prevent the formation of calcium-based stones.

B. This is the correct answer. Thiazide diuretics help reduce the excretion of calcium in the urine, which can be beneficial in preventing the formation of certain types of kidney stones, particularly calcium oxalate stones.

C. Thiazide diuretics do not directly increase the pH of the urine. They primarily reduce calcium excretion.

D. Thiazide diuretics do not dissolve existing kidney stones. They are used to prevent stone formation, not to treat existing stones.
