Rhonchi are commonly associated with which conditions?

• A. Asthma only
• B. Pulmonary embolism
• C. COPD, bronchiectasis, pneumonia, chronic bronchitis
• D. Pulmonary fibrosis

Answer: (C)

Rhonchi are low-pitched, coarse breath sounds caused by secretions moving through the larger airways. They indicate mucus in the airways that can be heard as a snoring or rattling sound and are often heard in conditions where there is excess mucus production in the larger airways. This pattern fits diseases like COPD, bronchiectasis, pneumonia, and chronic bronchitis, where mucus buildup and airway inflammation are common. In asthma, the hallmark sounds are usually wheezes from narrowed small airways, though mucus can be present; rhonchi are less typical there. Pulmonary embolism typically does not produce rhonchi and may have clear or non-specific lung sounds, while pulmonary fibrosis tends to create velcro-like crackles rather than rhonchi. So rhonchi align best with COPD, bronchiectasis, pneumonia, and chronic bronchitis.
