Which instruction is most accurate for fluid management between dialysis treatments?

• A. Limit fluids between treatments to minimize the amount of fluid that needs to be removed during dialysis.
• B. The goal is to keep interdialytic weight gain under 3 kg.
• C. Drink only water between treatments.
• D. Avoid all fluids on dialysis days.

Answer: (A)

Limiting fluid intake between dialysis sessions is the central idea here. Between treatments, the body accumulates fluid from what you drink and eat, known as interdialytic weight gain. The more fluid that builds up, the more dialysis must remove to bring you back to your dry weight. That larger ultrafiltration can lead to intradialytic hypotension, cramping, nausea, and strain on the heart. So telling patients to limit fluids helps keep fluid gains small and makes dialysis safer and better tolerated. A goal like keeping interdialytic weight gain under a certain amount (often around 2–3 kg) is a helpful target, but the core instruction is to limit fluids overall to minimize the amount of fluid that needs to be removed. Drinking only water or avoiding fluids on dialysis days isn’t correct because total fluid balance matters, and all fluids contribute to weight gain.
