Answer to Question 1

ANS: A
All pressure-controlled continuous mandatory ventilation breaths are time cycled.

Answer to Question 2

ANS: C
Intermittent mandatory ventilation is designed to deliver volume-targeted or pressure-targeted breaths at a set minimum frequency (i.e., it is time triggered). Between mandatory breaths, the patient can breathe spontaneously from the ventilator circuit without getting the set volume or pressure from the ventilator itself.
