A client with a history of renal calculus is prescribed potassium citrate. Which of the following is the primary purpose of this medication?

A. While increasing fluid intake can help with the passage of small stones, it is not likely to dissolve larger stones. The primary benefit of increased fluid intake is to help prevent the formation of new stones.

B. Drinking more fluids may help alleviate some discomfort, but the primary goal is not pain reduction.

C. This is the correct answer. Adequate fluid intake can help prevent the formation of new kidney stones by diluting the urine and reducing the concentration of minerals that can contribute to stone formation.

D. While adequate fluid intake can help reduce the risk of urinary tract infections, it is not the primary reason for recommending increased fluid intake in clients with kidney stones.

A. Excessive consumption of fruits and vegetables is not a primary cause of kidney stones. Some specific types of fruits and vegetables may contribute to stone formation, but it is not a general cause.

B. While genetic factors and family history can play a role in kidney stone formation, they are not the primary cause. The presence of minerals and salts in the urine is the main contributing factor.

C. An overactive bladder and frequent urination are not direct causes of kidney stone formation. They may be related to other urinary conditions but not to the formation of kidney stones.

D. This is the correct answer. Kidney stones are formed when certain minerals and salts in the urine form solid crystals that can clump together and grow into stones.
