Which of the following is considered a secure airway device?
a. Combitube c. Endotracheal tube
b. Berman airway d. Laryngeal mask airway
ANS: C

The esophageal cuff affords some protection from regurgitation, but, as with the laryngeal mask airway, the Combitube is not considered a secure airway device; neither is the Berman airway.
