Hang time for human breast milk in enteral nutrition guidelines is best described as:

• A. Change every 2 hours.
• B. Change every 4 hours.
• C. Change every 6 hours.
• D. Change every 8 hours.

Answer: (B)

Hang time is the maximum period a prepared enteral feed, such as expressed human breast milk, can remain in the feeding system (bag, tubing, or pump line) at room temperature before it must be discarded to limit bacterial growth. Human milk supports bacterial proliferation more readily than many formulas, especially if it’s warmed or held at room temperature. Because of this, guidelines specify a four-hour window for hang time. Shorter intervals would create unnecessary waste, while longer ones would raise the risk of contamination and infection. If milk is kept properly cooled before use, it can be stored longer before administration, but once connected for delivery, the four-hour rule applies.
