A nurse is providing education to a client who has experienced recurrent kidney stones. The client asks, "What can I do to prevent future kidney stones?" What is the nurse's best response?

A. Citrus fruits are generally not a concern for calcium oxalate stones. They are a good source of citrate, which may actually help prevent stone formation.

B. Dairy products are not specifically associated with calcium oxalate stones. However, high-calcium supplements might increase the risk, not dietary calcium from dairy products.

C. Red meat is not a significant concern for calcium oxalate stones. It is more associated with uric acid stones.

D. This is the correct answer. Leafy green vegetables are high in oxalates, which can contribute to calcium oxalate stone formation. Clients with calcium oxalate stones should limit their intake of these vegetables.

A. This is the correct answer. Calcium oxalate stones are common, and limiting the intake of foods high in oxalate, such as spinach, nuts, and certain other vegetables and fruits, can help reduce the risk of stone recurrence.

B. Increasing the intake of red meat and fish is not recommended to prevent calcium oxalate stones. In fact, high intake of animal protein may increase the risk of certain types of stones, such as uric acid stones.

C. Consuming carbonated beverages is not recommended to improve kidney function or prevent kidney stones. Some carbonated beverages may contain phosphoric acid, which can contribute to stone formation.

D. Avoiding dairy products is not recommended to prevent calcium oxalate stone formation. In fact, adequate dietary calcium intake from food sources may help reduce the risk of these stones.
