A nurse is reviewing the admission prescriptions for a 6-year-old child who has cystic fibrosis. For which of the following prescriptions should the nurse contact the child's provider?

A. Water-miscible vitamins A, D, E, and K are appropriate for a child with cystic fibrosis, as they are fat-soluble vitamins that the child may not absorb well. B. Airway clearance therapy should be performed after bronchodilator medications, not before. Bronchodilators help open the airways, which enhances the effectiveness of airway clearance therapy. C. A high-calorie, high-protein diet is recommended for children with cystic fibrosis due to increased energy needs. D. Using airway clearance therapy every 2 hours while awake is appropriate and ensures optimal lung function.
