Mechanical Ventilation Part 1 Questions
with Answers 100% Correct
A respiratory therapist determined a patient receiving mechanical ventilation developed Auto-
PEEP due to dynamic airflow obstruction. Which of the following should the therapist do? ✔✔
Decrease the mandatory rate
Spontaneous breathing trials with a T-piece have been initiated for a 50- year old patient who
has been receiving mechanical ventilation for 4 weeks. With each trial, the patient becomes
agitated, dyspneic, and tachypneic, and must be returned to the ventilator. Which of the
following should the respiratory therapist recommend? ✔✔ Initiate pressure support mode
Following placement of 8.0 mm ID tracheostomy tube, how much air should be placed into the
cuff? ✔✔ Enough to prevent a leak at peak inspiration
For a spontaneously breathing patient, which of the following will provide an elevated baseline
pressure during inspiration and expiration? ✔✔ CPAP
A patient receiving mechanical ventilation by a portable ventilation is being transported from
the emergency department to radiology. Which of the following is required during transport?
✔✔ Bag-valve resuscitator
A physician will be sedating a patient for a procedure and asks a respiratory therapist to monitor
the patient's ventilation. The therapist should select a ✔✔ Capnometer
A respiratory therapist is asked to position a patient for orotracheal intubation. The therapist
should place the patients's head ✔✔ In the sniffing position
, A patient has been receiving mechanical ventilation through a tracheostomy tube for 16 days.
The patient begins to thrash about in the bed following withdrawal of a drug-induced coma. The
patient's tracheostomy tube becomes dislodged. Following appropriate sedation, the therapist
should NEXT ✔✔ reinsert the tracheostomy tube
Which of the following is a characteristic of VC ventilation? ✔✔ Inspiration ends after delivery of
a preset volume

nasotracheal tube. Repositioning of the head does not allow passage of the catheter. Which of
the following should the respiratory therapist do? ✔✔ suction with a 12 Fr catheter
Immediately after initiating VC ventilation, an inverse I:E ratio is noted. Which of the following
does this indicate? ✔✔ Inspiratory flow is low
A patient who is afebrile is receiving VC ventilation with a heat moisture exchanger for the past
24 hours. There is a progressive increase in peak inspiratory pressure. Auscultation reveals
scattered coarse crackles, and thick secretions are obtained during suctioning. Which of the
following should a respiratory therapist do? ✔✔ Change to a heated humidifier
Which of the following should a respiratory therapist use to collect a sputum specimen for
sensitivity from an intubated patient? ✔✔ Lukens trap
An adult patient is receiving mechanical ventilation. Which of the following should be
recommended to improve oxygenation and recruit collapsed alveoli? ✔✔ PEEP
Which of the following should a respiratory therapist select to determine the rapid shallow
breathing index? ✔✔ Vane Respirometer
What is a major advantage of a heated wick humidifier compared with other types of
humidifiers? ✔✔ A relative humidity of 100% is easily produced
