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 statement is not correct. Increasing dairy product intake may provide calcium, which is important for overall health, but it is not a specific dietary modification to prevent struvite stones.

B. This is the correct answer. Struvite stones are composed of magnesium, ammonium, and phosphate. Limiting the intake of high-phosphorus foods can help prevent the formation of these stones.

C. Avoiding foods high in purines is more relevant to the prevention of uric acid stones, not struvite stones.

D. Limiting fluid intake is

not recommended for the prevention of struvite stones. Adequate fluid intake is essential in preventing stone formation.

A. Extracorporeal shock wave lithotripsy (ESWL) is typically used for smaller stones that can be broken up into smaller fragments and passed more easily. It is not usually recommended for large stones.

B. This is the correct answer. Percutaneous nephrolithotomy (PCNL) is a procedure used to remove larger kidney stones. It involves making a small incision in the back and inserting a nephroscope to directly visualize and remove the stone.

C. Ureteroscopy with laser lithotripsy is used for stones in the ureter, not in the kidney itself.

D. Cystoscopy with stent placement is used for conditions involving the lower urinary tract, such as the urethra and bladder, and is not typically used to remove kidney stones.
