A client undergoes extracorporeal shock wave lithotripsy. Before discharge, the nurse should provide which instruction?

• A. Increase your fluid intake to 2 to 3 liters per day.
• B. Limit fluids to 1 liter per day.
• C. Avoid fluids for 24 hours after the procedure.
• D. Stop drinking entirely.

Answer: (A)

After ESWL, stone fragments need to pass through the urinary tract. Drinking about 2–3 liters of fluids daily increases urine production, which helps flush those fragments out, reduces the risk of obstruction and painful passage, and supports healing of the urinary tract. Temporary blood in the urine can occur, but hydration helps dilute and move the fragments more smoothly. Limiting or stopping fluids would impede fragment passage and could lead to complications.
