Answer to Question 1

ANS: B
Breaths that are triggered by the mechanical ventilator are considered mandatory breaths because the ventilator is controlling the timing of the breath and delivering either a set volume or set pressure.

Answer to Question 2

ANS: A
Assisted breaths have characteristics of both mandatory and spontaneous breaths. In an assisted breath, all or part of the breath is generated by the ventilator, which does part of the work of breathing (WOB) for the patient. If the airway pressure rises above baseline during inspiration, which it does in this case, the breath is assisted.
