Which disease is characterized by wheezes with productive or nonproductive cough, representing a chronic airway disease?

• A. COPD
• B. Asthma
• C. Bronchitis
• D. Pneumonia

Answer: (A)

Chronic obstructive pulmonary disease describes a long-standing inflammatory process that causes persistent airflow limitation. In COPD, airways are narrowed, and that obstruction leads to wheezes, especially on exhalation, along with a cough that may be productive (with sputum) or nonproductive. This combination signals a chronic, progressive airway disease rather than an acute or episodic issue.

Asthma can also cause wheeze and cough, but its obstruction is typically reversible and symptoms are more episodic. Pneumonia presents as an acute infection with fever and lung consolidation, not a chronic pattern. Bronchitis can be either acute or chronic, but COPD best represents the enduring, progressive airway disease described by a chronic cough with or without sputum production.
