Answer D) Right intermediate bronchus
Explanation:
This child’s presentation is consistent with foreign body aspiration. The right main bronchus has a more vertical orientation when compared to the left main bronchus.
-
The trachea divides into the left main bronchus and the right main bronchus at the carina.
-
The right main bronchus then splits into the upper lobe bronchus, as well as the intermediate bronchus (bronchus intermedius), which subsequently splits into the right middle and lower lobe bronchi.
Because the right main bronchus is orientated more vertically than the left, the majority of aspirated foreign bodies are found in the right lung airways; more than half of these bodies are localized in the intermediate bronchus.
