In safe EN guidelines, which statement is correct regarding hang times for formulas used in open systems?

• A. Open-system hang time is unlimited.
• B. Closed-system hang time is up to 12 hours.
• C. Canned ready-to-use formulas should have a hang time no longer than 12 hours.
• D. Breast milk should never be used in enteral nutrition.

Answer: (C)

Hang time in enteral feeding is about how long a formula can stay in an open system before it must be discarded to minimize microbial growth. In open systems, exposure after opening increases contamination risk, so guidelines cap how long the formula can hang. The statement that canned ready-to-use formulas should have a hang time no longer than 12 hours reflects this safety limit for open systems and is the best guidance. Saying hang time is unlimited ignores the infection risk, and claiming a fixed 12-hour limit for closed systems isn’t accurate since closed systems are designed differently and can have different allowable times. Breast milk is not universally banned in enteral nutrition; it is used in appropriate patient populations with proper handling, so that option isn’t correct either.
