Which of the following interventions is most appropriate for a patient with Chronic Obstructive Pulmonary Disease (COPD) experiencing difficulty breathing due to increased secretions?

Rationale: A. Increasing the patient's fluid intake to 500 mL daily is incorrect because this amount is insufficient for thinning secretions. Adequate hydration is important in COPD to help mobilize mucus, but it typically requires 2–3 liters of fluid per day, unless contraindicated. B. Administering bronchodilators as prescribed is correct because bronchodilators relax the airway smooth muscles, improve airflow, and help the patient clear secretions more effectively. Short-acting bronchodilators, such as albuterol, can provide rapid relief from airway constriction, reduce dyspnea, and improve ventilation. This is a primary, evidence-based intervention for managing acute breathing difficulty in COPD with retained secretions. C. Encouraging the patient to lie flat to rest is incorrect because lying flat can worsen dyspnea and reduce lung expansion. Patients with COPD benefit from an upright or semi-Fowler’s position, which promotes chest expansion and helps mobilize secretions. D. Applying a cold compress to the patient's chest is incorrect because it does not improve airflow or secretion clearance. Warmth, such as from a warm shower or humidified air, may be more helpful in loosening secretions.
