A nurse is teaching a client with a history of struvite stones about dietary modifications to prevent stone recurrence. Which instruction should the nurse include in the client's plan of care?

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.

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.
