Answer to Question 1

ANS: C
When a ventilator malfunctions during use, the clinician must first ensure that the patient is being ventilated. When in doubt, the practitioner should disconnect the patient from the ventilator, start manual ventilation using a manual resuscitation bag, silence the alarms, and call for help.

Answer to Question 2

ANS: A
The first step in the process of assessment and documentation of patient-ventilator interaction after a patient has been placed on a mechanical ventilator involves the respiratory therapist veri-fying the physician's orders. The second step is to verify that the ventilator passed an operational verification procedure (OVP). The OVP involves checking the integrity of the ventilator circuit and the humidification system. The patient assessment is performed during the patient-ventilator system check.
