What is the recommended daily fluid intake for tube feeding?

• A. 30 ml/kg or 1 ml/kcal
• B. 20 ml/kg
• C. 40 ml/kg
• D. 50 ml/kg

Answer: (A)

In tube-fed patients, keeping them adequately hydrated is planned with a practical target: about 30 ml of fluid per kilogram of body weight per day, or roughly 1 ml of fluid for every kilocalorie of energy provided by the enteral formula. This rule ties hydration to both the person’s size and their energy needs, and it accounts for all sources of water—the fluid in the formula plus any additional free water given to flush the tube. For example, a 70 kg individual would aim for about 2,100 ml of fluid daily. If their formula supplies about 2,000 kcal, that rule helps ensure the total fluid aligns with their caloric intake, with free water added as needed to reach the target. In practice, monitor intake and output and adjust for medical conditions (kidney, heart, edema) as appropriate. The other stated amounts don’t reflect the standard approach to estimating daily hydration for tube feeding, which centers on this combined weight- or energy-based target.
