Which dietary change should be included in health teaching to help prevent another renal calculi attack?

• A. To increase dairy products
• B. To use antacids for indigestion and nausea
• C. To increase his intake of clear fluids
• D. To increase his intake of tea and chocolate

Answer: (C)

Keeping urine dilute by increasing fluids is the most helpful dietary change to prevent another renal stone attack. When you drink more water and other clear fluids, urine output rises and the concentration of mineral salts in urine decreases. This lowers the likelihood that minerals like calcium, oxalate, and uric acid will crystallize and form stones. Aiming for enough fluids to produce a steady, copious urine output—often about 2.5 to 3 liters of fluid intake daily, adjusted for the person’s needs—helps maintain this protective dilute urine state. The other options don’t support prevention as effectively. Increasing dairy products raises calcium intake, which can contribute to stone risk in some people if not balanced appropriately. Using antacids for indigestion can alter urine chemistry and sometimes add calcium, potentially promoting stone formation. Increasing tea and chocolate raises oxalate, a compound that can form calcium oxalate stones. So, prioritizing clear fluids to keep urine dilute is the best preventive strategy.
