What is the hang time range for closed-system enteral feeding containers?

• A. 6-12 hours
• B. 24-48 hours
• C. 12-24 hours
• D. 72 hours

Answer: (B)

Hang time is the maximum period a prepared enteral feeding container can stay in use after opening before it must be discarded. Closed-system containers are sealed, which reduces contamination risk and allows a longer safe window than open systems. The recommended range for these systems is 24–48 hours, reflecting a balance between safety and product stability. Going shorter (e.g., 6–12 or 12–24 hours) would unnecessarily increase waste and handling, while extending beyond 48 hours raises the chance of microbial growth or formula degradation. Therefore, 24–48 hours is the best fit.
