A. peak inspiratory pressure B. tidal volume C. peak flow D. inspiratory time - ANSWER: ✔✔A. peak inspiratory pressure The ventilator is a _______controller if the pressure waveform does not change when airflow resistance and compliance are changed. A. pressure B. flow C. volume D. A or B - ANSWER: ✔✔A. pressure Immediately after intubation, the therapist must: A. confirm the endotracheal tube placement with a chest radiograph. B. tilt and place the head into a sniffing position. C. displace the patient's tongue to the left side. D. inflate the cuff and check for bilateral breath sounds. - ANSWER: ✔✔D. inflate the cuff and check for bilateral breath sounds.
