A client with renal calculi asks the nurse about the most common symptom of kidney stones. What is the nurse's best response?

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. Diarrhea and abdominal cramping are not typically associated with kidney stone pain. These symptoms are more commonly seen in gastrointestinal disorders.

B. Painful and frequent urination may occur if the stone causes irritation in the bladder or urethra, but it is not a direct symptom of kidney stone pain.

C. Fatigue and generalized weakness are not specific symptoms of kidney stone pain. They may be associated with other medical conditions but are not directly related to renal calculus.

D. This is the correct answer. Nausea and vomiting are common symptoms that may accompany kidney stone pain, especially if the stone causes obstruction in the urinary tract. The pain and irritation can trigger a reflex that leads to nausea and vomiting.
