A client with a history of 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 C
Explanation
A. Reducing calcium intake is not typically recommended for uric acid stones. In fact, low calcium intake can increase the risk of other types of kidney stones.
B. Increasing consumption of red meat and shellfish is not recommended for uric acid stones. These foods are high in purines, which can increase uric acid levels in the body.
C. This is the correct answer. Uric acid stones are formed from high levels of uric acid in the urine. Purine-rich foods can contribute to elevated uric acid levels, so limiting these foods is important in managing uric acid stones.
D. Increasing intake of oxalate-rich foods is not specifically relevant to uric acid stones. Oxalate-rich foods are associated with calcium oxalate stones, not uric acid stones.
Correct Answer is D
Explanation
A. This is a correct statement. Drinking plenty of water is important to help flush out any stone fragments that may have resulted from the procedure.
B. This is a correct statement. Strenuous activities should be avoided for a few days after the procedure to allow for proper healing.
C. This is a correct statement. It is common to have some blood in the urine for a short time after ureteroscopy due to irritation and manipulation of the urinary tract during the procedure.
D. This statement is not correct. After the procedure, the client may be advised to follow a specific diet that is low in certain minerals (such as oxalate and calcium) that can contribute to stone formation. The nurse should provide specific dietary guidelines and restrictions to the client.
