Which lower respiratory condition shows rhonchi with clear or white sputum?

• A. Bronchitis
• B. Pneumonia
• C. COPD
• D. Asthma

Answer: (A)

Rhonchi come from secretions in the larger airways. When the bronchi are inflamed and producing mucus but there isn’t a focal lung infection or consolidation, you’re likely to hear these coarse, low-pitched sounds and the sputum tends to be clear or white rather than colored. That combination—rhonchi with clear or white sputum—fits bronchitis, where the main issue is inflammation of the bronchial tubes with mucus production rather than an alveolar infection.

In contrast, pneumonia usually presents with localized crackles and a productive, often colored sputum due to lung consolidation, along with fever or systemic symptoms. COPD can have chronic cough with mucus and auscultatory rhonchi, but the history is typically long-standing with breathlessness and a different pattern of airway involvement. Asthma commonly shows wheezes from reversible airway narrowing, and while mucus can be present, the hallmark sounds are wheezing rather than rhonchi tied to clear sputum.
