A client with a history of calcium oxalate stones asks the nurse, "Can I continue taking vitamin C supplements?" Which response by the nurse is appropriate?

A. Avoiding all dairy products is not a recommended prevention strategy for kidney stones. In fact, adequate dietary calcium may be beneficial for reducing the risk of certain types of stones.

B. Increasing dietary calcium intake, especially from food sources, may help prevent certain types of kidney stones, such as calcium oxalate stones.

C. Reducing fluid intake is not a recommended prevention strategy for kidney stones. Inadequate hydration can actually increase the risk of stone formation.

D. This is the correct answer. Drinking plenty of water and staying hydrated is one of the most effective ways to prevent kidney stones. Adequate hydration helps dilute urine and reduce the concentration of minerals that can lead to stone formation.

A. This statement is not correct. Limiting intake of calcium is not necessary for the prevention of uric acid stones. In fact, low calcium intake can increase the risk of other types of stones.

B. This is the correct answer. Uric acid stones are formed from high levels of uric acid in the urine. Purine-rich foods can contribute to elevated uric acid levels, so avoiding these foods is important in managing uric acid stones.

C. Increasing consumption of oxalate-rich foods like spinach is not relevant to preventing uric acid stones.

D. Reducing fluid intake is not recommended for preventing any type of kidney stone. Adequate fluid intake is essential for kidney health and preventing stone formation.
