Answer to Question 1

ANS: B
In the controlled mode the ventilator initiates all the breathing because the patient cannot. All ventilator initiated breaths are time triggered. Flow, pressure, and volume triggers are patient ini-tiated.

Answer to Question 2

ANS: C
The trigger mechanism ends the expiratory phase and begins the inspiratory phase. Limit is the maximum value that a variable may reach during inspiration. Cycle terminates the inspiratory phase. The baseline variable is applied during exhalation and is the pressure level from which a ventilator breath begins.
