Why do open-system enteral feedings have a shorter hang time?

• A. Because they are more likely to be exposed to contaminants
• B. They have higher caloric density
• C. They are more sensitive to temperature changes
• D. They are used in hospital settings only

Answer: (A)

Open-system enteral feedings have shorter hang times because they are not sealed from the surrounding environment. While you’re administering an open system, the formula is exposed to air and potential contaminants, which can enter the feed and multiply if left at room temperature. This increased risk of microbial contamination drives the need to discard the feed after a shorter period. Caloric density or temperature sensitivity aren’t the primary factors determining hang time; contamination risk from exposure is the key driver. Closed, sealed systems protect the contents from the environment, allowing longer hang times.
