A nurse is performing an assessment on a client with a history of recurrent kidney stones. Which risk factor is the nurse most likely to assess for in this client?

A. Uric acid stones may cause pain, but they do not typically present with costovertebral angle tenderness. Uric acid stones are more likely to be associated with gout and hyperuricemia.

B. Calcium oxalate stones are common and can cause pain, but they do not typically cause costovertebral angle tenderness. They are more likely to cause localized pain in the back or side.

C. This is the correct answer. Struvite stones, also known as infection stones, can cause severe pain that radiates to the back and lower abdomen. They are often associated with urinary tract infections, and the presence of an infection can lead to costovertebral angle tenderness.

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

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.
