A client with a history of kidney stones is prescribed potassium citrate. Which statement by the client indicates understanding of the medication's purpose?

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.

A. Sharp, stabbing pain in the lower abdomen is not typically associated with kidney stones. Kidney stone pain is usually felt in the back and flank regions of the body.

B. This is the correct answer. The pain caused by kidney stones is often described as a dull ache in the upper back and flank region, usually on the affected side where the kidney is located.

C. Burning sensation during urination is more commonly associated with urinary tract infections or inflammation of the urethra, not kidney stones.

D. Constant, generalized abdominal discomfort is not a specific symptom of kidney stones. Kidney stone pain is usually more localized to the back and flank regions.
