Which instrument is used for visual examination of the bronchi?

• A. Cilia
• B. Bronchoscope
• C. Cyanosis
• D. Expectorant

Answer: (B)

To directly view the airways inside the lungs, clinicians use an endoscope designed to reach the bronchial tree. That instrument is a bronchoscope, a slender tube with a light source and optics that can be passed through the nose or mouth into the trachea and bronchi. It provides real-time visualization of the bronchial mucosa, enabling assessment for blockages, inflammation, tumors, or infections, and also allows sampling or treatment as needed. Cilia are the hair-like structures lining the airways that help move mucus out, not an instrument. Cyanosis is a clinical sign of poor oxygenation, not a tool for examination. An expectorant is a medication used to loosen mucus, not something used to visualize the bronchi.
