muscles while breathing. Which of the following would be your first action at this

signal. The batteries are fully charged and the device was able to power-on. The
most likely cause of this problem is which of the following? - ANSWERa missing lead

abnormalities such as aneurysm, atherosclerosis, embolism, occlusion, stenosis,
thrombosis, trauma, or vasculitis? - ANSWERangiography

participating in a pulmonary rehabilitation program. Based on this finding, you can
conclude that the patient: - ANSWERhas smoked within the prior 12-24 hours

following observations would cause you to stop the trial and return the patient to
ventilatory support? - ANSWERdecrease in O2 saturation from 91% to 82%

patient to the homecare setting? - ANSWERwhether the patient is stable on low
FiO2s and PEEP

bedside spirometer? - ANSWERa large volume (3 L) calibration syringe
