Answer to Question 1

ANS: B
Lidocaine is commonly delivered by an atomizer to the nose, by mouthwash to the oropharynx, and by nebulizer and/or instillation through the bronchoscope to the lower airways.

Answer to Question 2

ANS: B
The risk of aspiration persists as long as the airway is anesthetized. Therefore, patients should remain in a sitting position and refrain from eating or drinking until sensation returns.
