What is a contraindication for bolus feedings in enteral nutrition?

The correct answer highlights that a contraindication for bolus feedings in enteral nutrition is when the feeding tube is placed into the jejunum or duodenum. Bolus feedings involve delivering a large volume of formula over a short period, which is typically suitable for gastric feeding since the stomach can effectively handle larger amounts and manage their gradual release into the small intestine.

In contrast, when a feeding tube is placed in the jejunum or duodenum, the continuous or small-volume feeding method is generally preferred. This is because these areas of the digestive system have a reduced capacity to handle larger boluses of fluid, and rapid administration of feedings can lead to complications such as dumping syndrome or increased risk of aspiration if the feedings are not appropriately managed. Therefore, tube placement in these locations indicates a need for cautious feeding approaches, making bolus feedings contraindicated in this context.
