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.

A. Pain relief is important in managing kidney stone pain, but potassium citrate is not primarily prescribed for this purpose.
B. Acid-base balance regulation may be one of the functions of potassium citrate, but it is not the primary purpose when prescribed to a client with renal calculus.
C. Urinary tract infection treatment is not the primary purpose of potassium citrate. While it may have some benefits in preventing certain types of urinary tract infections associated with stones, its primary purpose is not to treat infections.
D. This is the correct answer. Potassium citrate is prescribed to help dissolve certain types of kidney stones, particularly calcium oxalate stones and uric acid stones. It works by increasing the pH of the urine, making it more alkaline and less conducive to stone formation.
Correct Answer is C
Explanation
A. Alpha-blockers do not directly reduce inflammation in the urinary tract. They primarily work by relaxing the smooth muscle of the ureters, which can help ease the passage of kidney stones through the urinary tract.
B. Alpha-blockers do not dissolve kidney stones. They assist with stone passage by relaxing the ureters.
C. This is the correct answer. Alpha-blockers are prescribed to relax the smooth muscle of the ureters, allowing the stone to pass more easily through the urinary tract.
D. Alpha-blockers do not have a direct effect on preventing bacterial growth in the urinary tract. They are not antibiotics.
