Which symptom is associated with bronchitis?

1. Nonproductive cough

2. Clubbing nails

3. Productive cough

4. Barrel chest

The correct answer is: Productive cough

A productive cough is a hallmark symptom of bronchitis, particularly in cases of acute bronchitis. This condition involves the inflammation of the bronchial tubes, leading to increased mucus production. As the body responds to the irritation in the airways, it often results in coughing that brings up phlegm or mucus, which is what distinguishes a productive cough from a nonproductive one. Other symptoms associated with bronchitis may include wheezing, chest discomfort, and shortness of breath. A productive cough is significant as it reflects the body's attempt to clear mucus from the airways, which can help in easing breathing and reducing the risk of further infections. While nonproductive cough, clubbing of nails, and barrel chest are associated with different respiratory conditions, they do not typically characterize bronchitis. Nonproductive coughs are more common in conditions like viral infections, clubbing of nails can indicate chronic respiratory or circulatory issues, and barrel chest is often seen in chronic obstructive pulmonary disease (COPD) rather than bronchitis itself.
