What action should a nurse take for an infant with GERD to avoid regurgitation?

Thickening an infant's formula can help reduce regurgitation associated with gastroesophageal reflux disease (GERD) by increasing the viscosity of the feedings. This thicker consistency can help keep the contents of the stomach from easily flowing back into the esophagus, which is a primary concern for infants with GERD. Additionally, avoiding citrus juices is beneficial since these can exacerbate acid production and may irritate the esophagus.

In contrast, feeding the infant lying down can increase the likelihood of regurgitation, as the horizontal position does not support gravity in keeping stomach contents in place. Introducing solid foods immediately is not an appropriate intervention for very young infants; it is essential to wait until they are developmentally ready for solids to prevent further complications. Lastly, feeding every four hours does not specifically address the mechanisms of GERD and may lead to longer intervals without nutrition that may not be suitable for an infant's needs. Thus, thickening formula and avoiding irritants like citrus juices are the most effective strategies for managing GERD in infants.
