A patient receiving mechanical ventilation by a portable ventilator is being
transported from the ED to radiology. Which of the following is required
during transport?
A. bag-valve mask resuscitator
B. point-of-care blood gas analyzer
C. demand valve respirator
D. crash cart - Correct Answer-A. bag-valve mask resuscitator
A. A bag-valve mask resuscitator is required in case of transport ventilator
failure.
Mechanical ventilation was initiated for a patient, after which the PaCO2
decreased from 53 to 40 mm Hg. A respiratory therapist should expect
which of the following will increase?
A. HCO3 -
B. pH
C. PETCO2
Page | 1
,D. VD/VT - Correct Answer-B. pH
Carbon dioxide and pH move in opposite directions, so a decrease in
carbon dioxide will result in an increase in pH.
According to CLIA standards, quality control must be performed for blood
gas analyzers every
A. 8 hours.
B. 48 hours.
C. 72 hours.
D. 24 hours. - Correct Answer-A. 8 hours.
Eight hours is the CLIA-approved time frame for quality control of blood gas
analyzers.
While performing a patient-ventilator assessment, a respiratory therapist
observes very little condensation in the heated wire circuit. The reservoir of
the heated wick humidifier is full of water. The most likely explanation is
that the
A. minute ventilation is greater than 15 L/min.
B. patient circuit is operating normally.
C. flow is set at too low of a value.
D. room temperature is lower than normal. - Correct Answer-B. patient
circuit is operating normally.

,The heated wire circuit is designed to maintain gas temperature to prevent
condensation.
Which of the following devices must be used to comply with airborne
precautions?
A. N95 face mask
B. vinyl gloves
C. barrier gown
D. full face shield - Correct Answer-A. N95 face mask
An N95 face mask will provide protection against airborne microorganisms.
Which of the following imaging techniques is preferred when identifying
metastatic disease associated with non-small cell lung cancer?

, 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 druginduced coma. The patient's
tracheostomy tube has become dislodged. After the patient is
pharmacologically sedated, a respiratory therapist should NEXT
A. obtain an ABG sample.
B. perform nasal intubation.
C. reinsert the tracheostomy tube.
D. initiate oxygen therapy. - Correct Answer-C. reinsert the tracheostomy
tube.
After 16 days, the tracheostomy tract should be well established, and the
tube should be easily reinserted.
Following a bariatric surgery procedure 2 days ago, a patient with a PBW of
55 kg (121 lb) remains hospitalized with signs of sepsis. The patient is
intubated and receiving VC, A/C ventilation with the following settings:
FIO2 0.50
Mandatory rate 18/min
VT 350 mL
PEEP 12 cm H2O
After returning from radiology, the patient's
peak inspiratory pressure is 45 cm H2O and
