A nurse is developing a plan of care for a client who has COPD. The nurse should include which of the following interventions in the plan?

A. Restricting fluid intake is generally not recommended for COPD clients unless there is a specific fluid overload condition; adequate hydration helps thin mucus secretions. B. Pursed-lip breathing helps clients with COPD improve ventilation, reduce air trapping, and ease shortness of breath by prolonging exhalation and preventing airway collapse. This is a key breathing technique to teach. C. Clients with COPD often experience morning stiffness and increased symptoms, so scheduling exercise during the daytime or early afternoon is usually better than early morning. D. A high-protein, high-calorie diet is often recommended for COPD clients to maintain muscle mass and energy; a low-protein diet is not typically advised.
