What is the recommended hang time for open-system enteral feeding in the hospital?

• A. 12 hours
• B. 8 hours
• C. 24 hours
• D. 48 hours

Answer: (B)

Hang time refers to how long a prepared enteral formula in an open system can remain usable before it must be discarded. Open-system feeding exposes the formula to air and potential contamination when it’s poured into a reservoir, so the safe window is shorter than for closed systems. In hospital practice, about eight hours is the recommended limit to minimize bacterial growth while still allowing practical administration. If the formula isn’t used within that window or if there are signs of spoilage, it should be discarded. Closed systems have longer safe hang times, but still require strict storage and handling guidelines.
