Which of the following is a characteristic of enteral nutrition delivery methods for infants?

The characteristic of enteral nutrition delivery methods for infants is that it is administered via tubes for those unable to suck. Enteral nutrition is specifically designed to provide feeding directly into the gastrointestinal tract, which is especially beneficial for infants who may be premature, have congenital anomalies, neurological disorders, or other conditions that impair their ability to feed orally.

Using tubes to provide nutrition ensures that these infants receive the necessary calories and nutrients to support their growth and development, even when they cannot suck effectively or at all. This method allows for the continuity of nutritional intake without requiring the infant to rely on oral feeding, which may not be possible due to their medical condition.

Immediate oral feeding, functional gag reflex, and emergency use only do not align with the primary function and rationale behind the use of enteral feeding in infants. Oral feeding is typically introduced as soon as the infant is developmentally ready and able, a functional gag reflex is not a requirement for enteral feeding since the feeding method bypasses the need for these oral reflexes, and enteral nutrition is regularly employed in many situations, not exclusively emergencies.
