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

A. Excessive water intake is not a risk factor for kidney stones. In fact, adequate hydration is encouraged to prevent kidney stone formation.

B. Low dietary calcium intake is not a common risk factor for kidney stones. In some cases, excessive calcium supplementation may be a risk factor, but dietary calcium is generally not a concern.

C. This is the correct answer. Family history, a diet high in protein and salt, and dehydration are common risk factors for kidney stones.

D. Kidney stones are not mostly caused by consuming too many fruits and vegetables. Fruits and vegetables are generally considered beneficial for kidney health.

A. Fever and chills are more commonly associated with a urinary tract infection, which can sometimes be a complication of kidney stones. However, the severe pain described is more likely related to the presence of the stone itself.

B. This is the correct answer. Blood in the urine, also known as hematuria, is a common symptom of kidney stones. As the stone moves through the urinary tract, it may cause irritation and small blood vessels may be damaged, resulting in blood in the urine.

C. Difficulty starting the urine stream is not a specific symptom of kidney stones. It may be seen in other urinary conditions but is not typically associated with stones.

D. The frequent urge to urinate may be experienced if the stone causes irritation in the bladder, but it is not the most common symptom associated with kidney stones.
