A client with a history of kidney stones asks the nurse, "What can I do to prevent future kidney stones?" What is the nurse's best response?

A. Reducing calcium intake is not typically recommended for uric acid stones. In fact, low calcium intake can increase the risk of other types of kidney stones.

B. Increasing consumption of red meat and shellfish is not recommended for uric acid stones. These foods are high in purines, which can increase uric acid levels in the body.

C. 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 limiting these foods is important in managing uric acid stones.

D. Increasing intake of oxalate-rich foods is not specifically relevant to uric acid stones. Oxalate-rich foods are associated with calcium oxalate stones, not uric acid stones.

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.
