Why is a concentrated enteral formula recommended for nutritional management of chronic lung disease?

• A. To increase carbohydrate supply
• B. To restrict fluid intake due to edema
• C. To promote rapid growth
• D. To reduce fat absorption

Answer: (B)

In chronic lung disease, managing fluid status is a practical part of nutrition care because edema and fluid overload can worsen breathing difficulties and complicate treatment. A concentrated enteral formula delivers the same or greater calories in a smaller fluid volume, so you can meet the patient’s high energy needs without adding excess fluid to the diet. This is important because these patients often have increased work of breathing and higher energy expenditure, yet fluid restrictions may be in place to control edema or heart strain. By providing calories efficiently, you support weight and muscle preservation (and protein needs) while respecting fluid limits. Be sure to monitor hydration, electrolytes, and weight, adjusting as needed to avoid dehydration or electrolyte imbalances. Other goals like simply increasing carbohydrate supply, aiming for rapid growth in adults, or reducing fat absorption don’t align with the typical aims of this approach, which is to enhance energy intake within restricted fluid volume.
