Which nursing intervention would help maintain a patent airway for a male client with chronic obstructive pulmonary disease?

Teaching the client how to perform controlled coughing

Controlled coughing helps maintain a patent airway by helping to mobilize and remove secretions. A moderate fluid intake (usually 2 L or more daily) and moderate activity help liquefy and mobilize secretions. Bed rest and sedatives may limit the clients ability to maintain a patent airway, causing a high risk of infection from pooled secretions
