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.
