The nurse is developing a teaching plan for the parents of a 12-year-old boy with cystic fibrosis. For which piece of equipment should the nurse prioritize education?

Rationale: A. Flutter valve device: The flutter valve device helps loosen and clear thick mucus from the lungs, which is a primary concern in cystic fibrosis. Teaching parents how to properly use this device is essential to maintain airway clearance and reduce respiratory infections. B. Peak Flow Meter: While useful for monitoring lung function in asthma, the peak flow meter is less critical in cystic fibrosis management. It does not directly assist in clearing mucus or delivering medication. C. Nebulizer: Nebulizers are important for delivering inhaled medications and airway clearance therapies, but initial priority is often given to devices that facilitate mucus clearance like the flutter valve. D. Metered-dose inhaler: Metered-dose inhalers deliver bronchodilators or steroids but require coordination and proper technique, which can be challenging for some children. Education on this device is important but secondary to airway clearance tools in CF care.
