A nurse is providing discharge teaching about nutrition to the parents of a child who has cystic fibrosis (CF). Which of the following responses by the parents indicates an understanding of the teaching?

Rationale: A. Children with CF actually need increased salt intake, especially in hot weather, because they lose large amounts of sodium and chloride through sweat. B. Pancreatic enzymes are required with all meals and snacks to help digest nutrients and improve absorption, particularly fats and proteins. C. Low-fat and low-protein diets are not appropriate. Children with CF need a high-calorie, high-protein, high-fat diet to meet increased metabolic demands and compensate for malabsorption. D. Fluids should not be restricted. Adequate hydration is important to help thin respiratory secretions and prevent intestinal obstruction.
