Which of the following is a benefit of closed enteral feeding systems?

• A. Maximum hang time of 8-12 hours
• B. Decreased risk for microbial contamination
• C. Packaging amenable to addition of medication or modular
• D. Decreased incidence of gastric intolerance

Answer: (B)

Closed enteral feeding systems reduce the risk of microbial contamination by keeping the formula in a sealed, sterile bag or cassette and delivering it through a closed tubing setup. This minimizes handling and exposure to the environment, lowering the chances of introducing microbes during preparation and administration. The other options depend more on product guidelines or patient factors than on the system type itself, such as how long the formula is hung, whether medications can be added, or how well the patient tolerates the feed. Therefore, decreased risk for microbial contamination is the best-supported benefit.
