A nurse is caring for a client who has urolithiasis. Which of the following actions should the nurse take?

A. Implement NPO status: Clients with urolithiasis typically do not require NPO status unless they are scheduled for surgery or a procedure. Restricting oral intake unnecessarily can lead to dehydration, which may worsen stone formation or impede stone passage. B. Place the client on bedrest: Ambulation is encouraged for clients with urolithiasis to promote urinary flow and facilitate passage of stones. Bedrest is generally not indicated unless there are complications, so restricting mobility could hinder stone expulsion. C. Monitor the client's liver function: Liver function tests are not routinely affected by urolithiasis. Monitoring liver enzymes is unnecessary unless there is a separate hepatic condition or if the client is on medications that affect the liver. D. Strain the client's urine: Straining urine allows for collection of passed stones, which can then be analyzed to determine stone composition. This information guides dietary recommendations, pharmacologic interventions, and prevention strategies for future stone formation.
