A nurse is caring for a child who has cystic fibrosis and requires postural drainage. Which of the following actions should the nurse take?

Postural drainage should be performed before meals (or 1–2 hours after) to prevent nausea, vomiting, and aspiration from the mobilization of secretions. A bronchodilator is administered before (not after) postural drainage to open airways and maximize secretion clearance. Postural drainage is typically performed 2–4 times daily, not just twice. Chest percussion is performed with a cupped hand (not flat) to create vibrations that loosen secretions.
