In enteral nutrition formula safety, which practice is recommended?

• A. Mix or reconstitute enteral formulations at the bedside
• B. Change the enteral feeding administration set every 24 hours with open systems
• C. Limit hang time of closed system EN formulas to no more than 12 hours
• D. Store powdered formulas reconstituted in advance at room temperature for up to 24 hours

Answer: (C)

Safety of enteral nutrition hinges on keeping the formula free from contamination and limiting the time it is exposed to the delivery system. Closed-system formulas are designed to minimize contamination, but once the system is accessed for administration, the risk of microbial growth increases. Limiting how long the formula can hang in the tubing to 12 hours helps protect against contamination and ensures the formula remains within safe quality standards.

Reconstituting formulas at the bedside, using open systems, or storing reconstituted formula at room temperature all raise the risk of contamination or drug/ nutrient degradation and are not the preferred safety practices.
