Answer to Question 1

ANS: B
The amount and duration of the pressure applied to the airway, the mean airway pressure, ulti-mately influences the extent of the harmful cardiovascular effects. The lower the mean airway pressure, the less marked the cardiovascular effects. This pressure takes into account the peak in-spiratory pressure, the positive end-expiratory pressure, the inspiratory time, and the total cycle time.

Answer to Question 2

ANS: A
Succinylcholine resembles acetylcholine in chemical structure.
