A nurse is providing education to a client with cystic fibrosis (CF). Which dietary recommendation is most appropriate for the client?

"Limit your protein intake to reduce mucus production."

"Consume a high-fat diet to promote weight gain and calorie absorption."

"Avoid all dairy products to prevent lung congestion."

"Increase your intake of sugary snacks for quick energy."

Answer and Explanation

The Correct Answer is B

A) Incorrect. Protein intake is important for growth and repair but should not be limited in CF. High-calorie intake is more critical.

B) Correct. CF can lead to malabsorption of fat-soluble vitamins and calories, so a high-fat diet is recommended to support weight gain and nutrient absorption.

C) Incorrect. Dairy products are a good source of calcium and calories, and they are generally well-tolerated by CF patients. Avoiding them is not necessary.

D) Incorrect. Increasing sugary snacks is not advisable for CF patients. They need a balanced diet to meet their nutritional needs.
