Final answer:
To manage GER in an infant, the nurse advises the parents to keep the child in an upright position after feedings to utilize gravity in preventing reflux.
Step-by-step explanation:
The nurse informs the parents that the infant with gastroesophageal reflux (GER) should be maintained in an upright position after feedings. This position assists in managing reflux by utilizing gravity to help prevent the backflow of stomach contents into the esophagus. Keeping the head of the bed elevated can also aid in reducing reflux symptoms during sleep. Other lifestyle changes, such as avoiding certain foods, decreasing portion sizes, and not eating right before bedtime, can additionally decrease the amount and acidity of reflux.
