A nurse is caring for a client with struvite stones. Which dietary recommendation should the nurse include in the client's plan of care?

A. Calcium oxalate stones may cause pain, but they do not typically radiate to the groin. They are more likely to cause localized pain in the back or side.

B. This is the correct answer. Uric acid stones can cause sudden and severe pain that radiates from the back to the groin. The pain is often described as colicky and is associated with restlessness.

C. Struvite stones are typically associated with urinary tract infections and may not cause the sudden and severe pain described in the question.

D. Cystine stones are rare and are more likely to cause chronic, dull pain rather than sudden and severe pain.

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.
