A nurse is reinforcing teaching with a parent of an infant who has gastroesophageal reflux. Which of the following statements by the parent indicates an understanding of the teaching?

Choice A reason: Side-lying during sleep is not recommended for infants with gastroesophageal reflux, as it may increase reflux risk compared to upright positioning. The American Academy of Pediatrics advises against side-lying due to sudden infant death syndrome risks. Upright positioning post-feeding reduces reflux, making this statement incorrect. Choice B reason: Breast milk is suitable for infants with gastroesophageal reflux, as it is easily digestible and does not require switching to formula. Both feeding types benefit from upright positioning post-feeding to reduce reflux. This statement is incorrect, as it suggests an unnecessary change, indicating a misunderstanding of reflux management. Choice C reason: Keeping an infant upright after feedings reduces gastroesophageal reflux by using gravity to prevent stomach contents from flowing back into the esophagus. This minimizes regurgitation and irritation, promoting comfort and reducing complications like esophagitis, making this statement correct and reflective of proper reflux management in infants. Choice D reason: Thickening formula with oatmeal is not universally recommended, as it may not be suitable for all infants and requires medical guidance. Oatmeal can increase caloric density or cause choking. Upright positioning is a safer, evidence-based practice to reduce reflux, making this statement less accurate than upright positioning.
