Which description best describes a productive cough?

• A. A cough without mucus
• B. A bark-like cough
• C. A cough that brings up mucus/phlegm
• D. A dry cough

Answer: (C)

A productive cough is defined by the production and expulsion of mucus from the airways. When sputum or phlegm is brought up, it means secretions are being mobilized and cleared from the bronchial passages, which is the hallmark of a productive cough. This contrasts with a dry or nonproductive cough, where no mucus is produced, and with a bark-like quality that describes the sound rather than the presence of secretions. Therefore, describing a cough that brings up mucus or phlegm best fits the concept of a productive cough. In clinical practice, noting sputum (color, amount, odor) helps guide diagnosis and treatment.
