Question: Chronic Bronchitis is characterised by:

Option 1: Hyper-expansion of the chest
- This feature is more commonly associated with emphysema and hyperinflated lungs seen in some COPD phenotypes, not the defining hallmark of chronic bronchitis. While chronic lung disease can show some hyperinflation, it is not the classic characterization of chronic bronchitis.

Option 2: Bronchospasm and productive cough
- Bronchospasm is typical of conditions like asthma where smooth muscle constriction is a prominent feature. In chronic bronchitis, the key issue is mucus hypersecretion rather than recurrent bronchospasm, so this combination misattributes the core pathophysiology.

Option 3: Dyspnoea and bronchospasm
- Dyspnea can be present in many lung conditions, but bronchospasm is not the defining mechanism of chronic bronchitis. The typical picture centers on mucus production and airway inflammation, not primarily reversible smooth muscle constriction.

Option 4: Productive cough, dyspnoea and copious sputum production
- This option aligns with the standard description of chronic bronchitis: a productive cough with mucus production that persists for at least several months over consecutive years, often accompanied by dyspnea due to airway obstruction. The phrase “copious sputum production” reflects the hallmark mucus hypersecretion that characterizes chronic bronchitis within chronic obstructive pulmonary disease (COPD).

In summary, the defining feature of chronic bronchitis is the chronic productive cough with substantial sputum production, which is best captured by Option 4. The other options misrepresent the core pathophysiology by emphasizing hyperinflation, bronchospasm, or focusing on dyspnea without the central mucus overproduction.
