What is the preferred method for protecting the airway in emergency airway management?

• A. Oropharyngeal airway
• B. Endotracheal intubation
• C. Laryngeal mask
• D. Nasal airway

Answer: (B)

Securing a definitive airway with a cuffed endotracheal tube is the method that reliably protects the airway in emergencies. The tube sits inside the trachea and, with the cuff inflated, creates a seal that prevents aspiration of gastric contents while allowing controlled, protective ventilation. Oropharyngeal and nasal airways simply keep the airway open but do not guard against regurgitation, making them temporary or adjunctive devices rather than protective airways. A laryngeal mask airway seals above the glottis and can facilitate ventilation, but it does not consistently prevent aspiration and is considered a bridge or rescue device rather than a definitive airway. Therefore, endotracheal intubation is the preferred approach for airway protection in emergency management.
