What is the most effective way to assist a child with cystic fibrosis in managing their condition?

Ensuring proper nutrition and hydration is crucial in managing cystic fibrosis because the condition significantly impacts the digestive and respiratory systems. Children with this condition often have difficulty absorbing nutrients due to pancreatic insufficiency, which can lead to malnutrition and poor growth. A well-balanced diet that incorporates high calories, protein, and fat is essential for supporting their overall health and energy needs.

Hydration plays a vital role as it helps to thin mucus secretions, making them easier to clear from the lungs, thus improving respiratory function. Additionally, children with cystic fibrosis may be at a higher risk of dehydration due to increased sweat production, particularly in warmer climates or during vigorous activity. Therefore, focusing on proper nutrition and maintaining adequate hydration is fundamental in managing cystic fibrosis effectively, enhancing growth and lung function while minimizing complications related to the disease.

The other options do not address the core needs of a child with cystic fibrosis effectively. Limiting physical activity can hinder lung function and general well-being, encouraging prolonged bed rest counteracts the need for physical activity, and while high-calorie snacks might seem beneficial, they are not a comprehensive approach to the child's overall nutritional management and hydration needs.
