Which formula approach is most appropriate in infants with chronic lung disease?

• A. High fat low carbohydrate formula
• B. Use of concentrated formula
• C. Hydrolyzed protein formula
• D. MCT oil predominant formula

Answer: (B)

Infants with chronic lung disease have higher energy needs because of the extra work of breathing, but they often tolerate only limited fluid volumes. Using a concentrated, energy-dense formula increases calories per ounce, allowing meeting daily energy goals without raising total fluid intake. This supports adequate growth and reduces respiratory workload and risk of fluid overload. The other options don’t directly address the dual need for high energy intake within a restricted fluid volume: a protein hydrolysate addresses protein intolerance rather than caloric density; a formula high in MCTs targets fat digestion issues rather than overall energy delivery; and a high-fat, low-carbohydrate approach alters macronutrient balance without solving the core issue.
