Why is fluid restriction indicated in infants with chronic lung disease?

• A. To prevent dehydration
• B. To manage fluid buildup around heart and lungs
• C. To improve hydration
• D. To reduce caloric intake

Answer: (B)

Fluid management to prevent fluid overload and edema around the lungs and heart is the key idea. In infants with chronic lung disease, excess fluid can raise hydrostatic pressure and lead to pulmonary edema and pleural or pericardial effusions. This fluid buildup worsens gas exchange, increases work of breathing, and can compromise oxygenation. Limiting fluids helps keep intravascular and interstitial volumes lower, reducing edema and easing lung function, which supports better breathing and oxygen delivery. It’s not about preventing dehydration, improving hydration, or reducing calories—the goal is to prevent fluid overload that can worsen respiratory status.
