Which statement best distinguishes chronic bronchitis from emphysema in COPD?

• A. Chronic bronchitis presents with dry cough; emphysema with productive cough
• B. Emphysema presents with productive cough; chronic bronchitis with dry cough
• C. Chronic bronchitis presents with productive cough and rhonchi; emphysema with dry cough
• D. Both present with identical symptoms

Answer: (C)

Chronic bronchitis and emphysema show different clinical clues, especially regarding cough and mucus. Chronic bronchitis is defined by a chronic productive cough with mucus production, so auscultation often reveals rhonchi from airway secretions. Emphysema, on the other hand, typically presents with prominent dyspnea and a dry cough with little sputum, and examination may show diminished breath sounds and hyperresonance from air trapping. This statement captures that contrast by pairing a productive cough with rhonchi for chronic bronchitis and a dry cough for emphysema, which is the best way to distinguish the two within COPD. The idea that both have identical symptoms or that cough types are swapped between the conditions doesn’t fit the usual clinical picture.
