What is the typical goal of keeping the head of the bed elevated during tube feedings?

Keeping the head of the bed elevated during tube feedings is primarily aimed at preventing gastric reflux. By elevating the head of the bed, gravity helps to keep the feedings in the stomach rather than allowing them to flow back into the esophagus, which can lead to aspiration and other complications. This positioning is especially important in patients who may have impaired gastrointestinal function or are at higher risk for aspiration due to altered consciousness or coexisting medical conditions. While the other options address potential benefits or goals of tube feeding, preventing gastric reflux is the primary reason for this specific positioning during feedings.
