In airway management, where is the obstruction located if it is above the trachea?

• A. Upper airway obstruction
• B. Tracheal obstruction
• C. Lower airway obstruction
• D. Alveolar obstruction

Answer: (A)

The item tests understanding of airway segmentation by location. If the obstruction is above the trachea, it lies in the upper airway—the nasal passages, mouth, pharynx, and larynx. The trachea itself is below this region, so a blockage there would be a tracheal obstruction. Obstructions lower in the airway involve the bronchi and bronchioles, and alveolar obstruction affects the air sacs in the lungs. Recognizing that “above the trachea” means upper airway clarifies why the correct choice is upper airway obstruction.
