Choice A rationale:

Encouraging physical activity and exercise is important in managing CF.

It helps improve lung function and overall health in individuals with CF.

Choice B rationale:

Administering pancreatic enzyme replacement therapy is a crucial part of CF management.

CF often affects the pancreas, leading to malabsorption, and these enzymes help digest and absorb nutrients properly.

Choice C rationale:

Restricting fluid intake to reduce mucus production is not a recommended intervention for CF.

Hydration is essential to keep mucus from becoming too thick and sticky.

Dehydration can worsen mucus obstruction.

Choice D rationale:

Teaching airway clearance techniques is essential in CF management.

It helps individuals clear the thick mucus from their airways, promoting better lung function.

Choice E rationale:

Promoting a high-fat, high-calorie diet is important for individuals with CF.

CF often leads to malnutrition, and a high-calorie diet helps maintain proper nutrition and growth.
