Final answer:
The nurse should plan to feed a preterm newborn with small amounts of formula at each feeding to prevent respiratory embarrassment and support homeostasis.
Step-by-step explanation:
To feed a preterm newborn who has a strong sucking reflex and to prevent respiratory embarrassment, the nurse should plan to feed the infant with small amounts of formula at each feeding. This approach minimizes the risk of aspiration, which can occur if the infant is fed too quickly or in large volumes. It's important to ensure that preterm infants are properly supported during feeding, and that the formula is given at a pace that allows them to breathe comfortably.
Newborn reflexes such as sucking and rooting are potent and help the infant to feed effectively. However, in the case of a preterm newborn, their systems, including the respiratory and digestive systems, are still developing. Feeding small amounts more frequently can help these infants get the nutrition they need without overwhelming their capacity to handle feedings. It is also critical to maintain homeostatic balance in these fragile newborns, considering aspects like fluid intake and thermoregulation as they undergo postnatal adjustments. Frequent but small feedings are conducive to this aim.
