A nurse is caring for a client who has chronic obstructive pulmonary disease (COPD). The client tells the nurse. "I can feel the congestion in my lungs, and I certainly cough a lot, but I can't seem to bring anything up." Which of the following actions should the nurse take to help this client with tenacious bronchial secretions?

Rationale: A. Encouraging the client to drink 2 to 3 L of water daily helps thin tenacious secretions, making them easier to expectorate and improving airway clearance. B. Maintaining a semi-Fowler's position promotes lung expansion and ease of breathing but does not directly thin secretions. C. A low-salt diet may help manage fluid retention in some conditions but does not affect mucus viscosity in COPD. D. Administering oxygen improves oxygenation but does not address the issue of thick bronchial secretions.
