Which statement identifies the definitive airway?

• A. A supraglottic airway is considered definitive
• B. An oropharyngeal airway is considered definitive
• C. A nasal airway is considered definitive
• D. An endotracheal tube is considered definitive

Answer: (D)

Definitive airway means a device that provides a secure, protected path into the trachea with a reliable seal for controlled ventilation. The endotracheal tube does this by being inserted through the vocal cords into the trachea and inflating a cuff to seal the airway. That seal protects the lower airway from aspiration and allows precise, positive-pressure ventilation, even when the patient can’t protect their own airway. In contrast, a supraglottic device sits above the glottis and, while it can ventilate, it doesn’t offer the same level of protection and security; it’s usually considered a temporary or rescue airway. Oropharyngeal and nasal airways simply keep the upper airway open and do not protect the lower airway or guarantee effective ventilation in all patients. Therefore, the endotracheal tube is the definitive airway.
