In acute care for a COPD patient presenting with dyspnea, which action is most appropriate initial management?

• A. Initiate mechanical ventilation
• B. Administer oxygen
• C. Obtain imaging studies
• D. Administer antibiotics

Answer: (B)

The first priority in an acute COPD flare with shortness of breath is to secure adequate oxygenation. Administer supplemental oxygen to raise the blood oxygen level and relieve the work of breathing, while carefully titrating to a target that COPD patients typically tolerate well—about 88–92% saturation—to avoid oversupply that can worsen CO2 retention. This immediate step addresses the life-threatening threat of hypoxemia and buys time for other treatments to take effect.

Mechanical ventilation is reserved for cases of impending respiratory failure or when noninvasive support cannot maintain gas exchange. Imaging studies are important for diagnosis but don’t quickly alleviate dyspnea or correct oxygenation. Antibiotics are appropriate if there’s clear evidence of infection or a high suspicion of bacterial exacerbation, not as a blanket initial move. In practice, bronchodilators and steroids are often started promptly alongside oxygen, but the essential first action to stabilize the patient is providing supplemental oxygen with careful monitoring.
