What does COPD stand for?

• A. Chronic Obstructive Pulmonary Disease
• B. Chronic Obstructive Pulmonary Disorders
• C. Acute Respiratory Disease
• D. Paroxysmal Nocturnal Dyspnea

Answer: (A)

COPD stands for Chronic Obstructive Pulmonary Disease. This name reflects a long-lasting, non-reversible problem with airflow in the lungs. “Chronic” means it persists over time; “Obstructive” indicates narrowed airways that make it hard to exhale air; “Pulmonary” points to the lungs; and “Disease” signals a medical condition rather than a temporary symptom. COPD includes conditions like emphysema and chronic bronchitis, usually caused by long-term exposure to irritants such as cigarette smoke or air pollutants. The other options use terms that don’t fit COPD’s nature: “disorders” suggests multiple issues, “acute” contradicts its chronic course, and a symptom like paroxysmal nocturnal dyspnea is not a disease name.
