The nurse practitioner is providing anticipatory guidance to the caregiver of a child with cystic fibrosis. The most appropriate advice about dietary management should include:

Rationale: A. Limiting fats is inappropriate for children with cystic fibrosis (CF) because they require a high-calorie, high-fat diet to maintain growth due to malabsorption. B. Increasing calories by 50% is appropriate, but limiting salt is not recommended; children with CF often require extra salt due to excessive losses in sweat. C. While vitamins are important, CF patients require fat-soluble vitamins (A, D, E, K) rather than B complex and C specifically. D. Adding pancreatic enzymes four to five times a day is essential for children with CF who have pancreatic insufficiency. These enzymes aid in digestion and absorption of nutrients, improving growth and nutritional status.
