What is typically NOT a characteristic of chronic bronchitis?

• A. Inflamed airways
• B. Cough with mucus
• C. Obstruction of airflow
• D. Rapid lung expansion

Answer: (D)

Chronic bronchitis is characterized by persistent inflammation of the airways, leading to symptoms such as a productive cough with mucus and obstruction of airflow due to narrowing of the bronchi. The condition results from long-term exposure to irritants like tobacco smoke, which causes chronic inflammation, and is typically marked by the production of excess mucus. In the context of lung function, rapid lung expansion is not a characteristic of chronic bronchitis. Instead, this condition usually results in difficulty exhaling air due to the narrowing and obstruction of the airways, leading to a feeling of air trapping and decreased lung volumes during forced expiration. The absence of rapid lung expansion reflects the obstructive nature of chronic bronchitis, where proper airflow is compromised rather than facilitated.
