What are two advantages of closed enteral feeding systems?

• A. Decreased microbial contamination
• B. Longer hang time
• C. Reduced nursing time
• D. Longer hang time and reduced nursing time

Answer: (D)

Closed enteral feeding systems minimize exposure of the formula to the environment and handling, helping to preserve sterility and formula integrity. The two advantages most emphasized are longer hang time and reduced nursing time. With a closed system, the reservoir is sealed and pre-filled, allowing feeds to stay connected and be hung for longer periods before a change is required, which reduces interruptions and the frequency of bag and tubing changes. At the same time, nursing time is reduced because setup is simpler and there’s less need for frequent sterile preparation, cleaning, or aseptic transfers between bags and tubing. This combination improves workflow and reduces staff workload. While reduced contamination risk is another benefit of closed systems, the exam highlights the practical workflow advantages of longer hang time and less nursing effort.
