When extubating an adult patient, which of the following should a
respiratory therapist do FIRST?
A. Deflate the cuff
B. Remove the tube holder from the patient's face
C. Position the patient in an upright position
D. Suction while the patient coughs
Position the patient in an upright position
Explain:
A. Deflating the cuff should be the last step prior to removing the
endotracheal tube.
B. Removing the tape is not the first step in extubating.
C. The patient should first be placed in high Fowler's position.
D. Suctioning should be performed only after positioning the
patient in an upright position.

A male patient who is 80 kg (176 lb) and 180 cm (5 ft 11 in) is
orally intubated with a 7.0 - mm ID endotracheal tube. Mechanical
ventilation was initiated with an HME in the circuit. Suctioning the
patient's secretions effectively after seven days has becom e
increasingly difficult. The respiratory therapist should
1. Use a smaller suction catheter.
2. Replace the HME with a heated humidifier.
3. Recommend changing to a larger endotracheal tube.
4. Administer dornase alfa (Pulmozyme)
A. 1 and 2 only
B. 1 and 4 only
C. 2 and 3 only
D. 3 and 4 only
2 and 3 only
Explain:
1. False. If an appropriate size catheter cannot remove the
secretions, a smaller catheter would be less likely to help in this
situation.
,Page 3 of 282
2. True. A heated humidifier may be more effective than an HME if
the secretions are thick.
3. True. A 7.0 tube is relatively small for a man of this size. A
larger endotracheal tube would allow for therapeutic
bronchoscopy to remove secretions and may also reduce airway
resistance.
4. False. There is no indication that dornase alfa is indicated at
this time.
A respiratory therapist is preparing a bronchoscope for a
scheduled procedure. The bronchoscope is plugged into the light
source and powered on. No light appears at the distal end of the
bronchoscope. The therapist should FIRST
A. Replace the light bulb in the bronchoscope
B. Notify the physician that the procedure should be rescheduled
C. Ensure the light cable is seated correctly in the connection
port
D. Connect the light source to a different outlet
Ensure the light cable is seated correctly in the connection port
Explain:
, Page 4 of 282
A. The positioning of the light cable in the connection port should
be checked before replacing the light bulb.
B. Additional troubleshooting steps should be performed before
rescheduling the procedure.
C. The most common cause of issues with the light source of
bronchoscopes is the connection port.
D. Since the bronchoscope is powered on, trying a different outlet
is unlikely to solve the issue.
A 58 - year- old male presents to the ED with a chief complaint of
acute chest pain. Which of the following diagnostic tests should
be done FIRST?
A. Electrocardiography
B. Chest radiograph
C. CT scan of the chest
D. Cardiac ultrasound
Electrocardiography
Explain:
A. An ECG is required to rule out an acute myocardial infarction
or arrhythmia before considering other diagnoses.
