A client with renal calculi is preparing for discharge after an extracorporeal shock-wave lithotripsy (ESWL) removal. Which instruction should the nurse include in the client's postoperative discharge teaching?

Choice A reason: Restricting physical activities is not necessary after ESWL. Clients are encouraged to resume normal activity to promote stone fragment passage. Choice B reason: Incentive spirometer use is indicated after thoracic or abdominal surgery to prevent atelectasis, not after ESWL. Choice C reason: Monitoring urinary stream for decreased output is critical because obstruction from residual stone fragments can occur. Decreased urine output may indicate obstruction or complications such as hydronephrosis, requiring immediate medical attention. Choice D reason: Hematuria is expected after ESWL and typically resolves within 24–48 hours. Reporting pink-tinged urine is unnecessary unless bleeding is heavy or prolonged.
