Which statement best describes why gastric feedings can be delivered by bolus and intermittent methods?

• A. The stomach rapidly empties causing reflux
• B. Bolus feeding doesn't require a pump
• C. The stomach serves as a reservoir thus delaying rapid emptying of formula into the small bowel
• D. Intermittent feeding is always preferred

Answer: (C)

The stomach acts as a reservoir that delays delivery of formula into the small bowel, so administering nutrition in boluses or intermittent amounts can be tolerated. By holding a defined volume and releasing it gradually, the gastric emptying rate is moderated, preventing a sudden influx into the intestine and reducing load-related intolerance. This physiologic buffering is what allows bolus and intermittent gastric feedings to be feasible. The other statements don’t capture this mechanism: rapid emptying isn’t what enables these methods, the need for a pump is just a logistical detail, and intermittent feeding isn’t always preferred for every patient.
