A client with recurrent kidney stones is prescribed thiazide diuretics. The nurse should recognize that these medications help prevent stone formation by:
Increasing the excretion of uric acid
Reducing the excretion of calcium in the urine
Increasing the pH of the urine
Dissolving existing kidney stones
The Correct Answer is B
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.

Correct Answer is B
Explanation
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.
Correct Answer is D
Explanation
A. This statement is not correct. Adequate fluid intake is essential to help prevent kidney stones. Restricting fluid intake can increase the concentration of minerals in the urine and promote stone formation.
B. This statement is not correct. While calcium oxalate stones are common, reducing calcium intake is not recommended for most people. In fact, a low-calcium diet may increase the risk of other types of kidney stones.
C. This statement is not correct. Fruits and vegetables contain valuable nutrients and should not be avoided. However, some fruits and vegetables are high in oxalate, which may contribute to the formation of calcium oxalate stones. The key is to consume a balanced diet and drink plenty of fluids.
D. This is the correct answer. Adequate fluid intake is crucial in preventing kidney stones. It helps dilute the urine and reduce the concentration of minerals that can lead to stone formation.
