A nurse is providing education to a client who has been diagnosed with renal calculus. The client asks, "What causes kidney stones?" What is the nurse's best response?

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. This is a correct statement. Drinking plenty of water is important to help flush out any stone fragments that may have resulted from the procedure.

B. This is a correct statement. Strenuous activities should be avoided for a few days after the procedure to allow for proper healing.

C. This is a correct statement. It is common to have some blood in the urine for a short time after ureteroscopy due to irritation and manipulation of the urinary tract during the procedure.

D. This statement is not correct. After the procedure, the client may be advised to follow a specific diet that is low in certain minerals (such as oxalate and calcium) that can contribute to stone formation. The nurse should provide specific dietary guidelines and restrictions to the client.
