Which statement about infectious complications with enteral feedings is true?

• A. Exceeding hang-time guidelines is not a risk for contamination
• B. Bacterial contamination may originate from the patient's throat, lung and stomach
• C. Open systems have less exogenous bacterial contamination
• D. The enteral tube site should be routinely cultured

Answer: (B)

Infectious complications from enteral feedings arise mainly from contamination by bacteria that are already part of the patient’s own flora or from exposure during handling. The best statement recognizes that bacterial contamination may originate from the patient’s throat, lung, and stomach. This reflects how oral secretions and gastric contents can be sources of bacteria that reach the feeding system or are aspirated into the lungs, especially if there is reflux or breakthrough barriers around the tube. Proper practices—using closed systems when possible, adhering to hang-time guidelines, and careful aseptic handling—help minimize these risks. In contrast, exceeding hang-time increases contamination risk, open systems tend to have more exogenous contamination due to handling and environmental exposure, and routine culture of the enteral tube site is not recommended unless there are signs of infection, since colonization does not always indicate a problem requiring culture.
