A 30-weeks of gestation infant is receiving mechanical ventilatory support with a time-cycled,
pressure-limited ventilator at the following settings:
PIP 35 cm H2O
Rate 28
FIO2 0.4
PEEP 4 cm H2O
I-time 0.75 sec
The respiratory therapist notices the pressure manometer does not rise to the set pressure
during each inspiration. Which of the following is the most likely cause?
A. the pressure-limiting pop-off valve is set to low
B. internal flow rate is too high
C. rate is insufficient
D. set pressure exceeds the pressure capability of the ventilator –

A respiratory therapist is administering epinephrine directly down the ET tube of a patient in
full cardiopulmonary arrest. What is the most important procedural consideration?
A. must wait 10 minutes in between dosage administrations

A patient with a laryngectomy tube in place, following surgical removal of the vocal folds,
requires invasive mechanical ventilatory support due to ventilatory failure manifested by
arterial blood gas analysis. Which of the following should the respiratory therapist do?
A. remove the laryngectomy tube
B. surgically install a tracheostomy tube
C. intubate through the laryngectomy tube
D. connect a 15/22 mm adapter to the end of the laryngectomy tube –
Correct Answer :The correct answer is : C
Immediately upon intubating a 55-year-old male who is 178 cm (5 ft 10 in) tall and weighs 78
kg (172 lbs), with a 6.5-mm ET tube, the respiratory therapist inserts air into the ET tube cuff
until the pressure reaches 22 mm Hg. Despite the cuff pressure, a rather large amount of air is
escaping around the cuff with each mechanical inspiration. Additional air injected into the cuff
does not solve the problem. What is the most likely problem?
A. The pressure-reading manometer is faulty.
B. The cuff is most likely herniated.
C. The endotracheal tube is too small.
D. The tube is in the esophagus. - Correct Answer :The correct answer is : C
The respiratory therapist is observing a chest radiograph to determine the location of a
pulmonary artery catheter. If placed properly, the therapist will expect to see the end of the
catheter positioned where?
A. centered in the mediastinal area
B. just over the heart in the left lung field
C. in the left apical region
D. in the right lower lung field - Correct Answer :The correct answer is : D
