- An infant is being mechanically ventilated via a time-
cycled, pressure-limited ventilator. Which of the following
would occur if PEEP were increased without a
corresponding increase in peak pressure? - Answer-The
tidal volume would decrease
- A physician requests the respiratory therapist to assess
the upper airway function of a patient with a fenestrated
tracheostomy tube. The therapist should: - Answer-
Remove the inner cannula, deflate the cuff, plug the outer
cannula
- A patient receiving sustained maximal inspiratory (SMI)
treatments with a volume-oriented incentive spirometer
device begins to inhale through the device 18 times per
minute. Which of the following best explains this situation?
- Answer-The patient needs re-instruction regarding the
SMI therapy

- After initiating mechanical ventilation in the A/C mode for
an adult male patient, the respiratory therapist observes
that the patient is agitated and having difficulty in cycling
the ventilator. Which of the following should the therapist
do? - Answer-Increase the sensitivity setting
- Data recorded for a 52 kg (110 lb) mechanically
ventilated patient who has a long standing history of
chronic hypercapnia are as follows:
Ventilator Settings Arterial Blood Gases
Mode: SIMV
pH: 7.36
VT: 400 mL
PaCO2: 62 mmHg
Rate: 8/min
HCO3: 34 mEq/L
FiO2: 0.35
PaO2: 61 mmHg
On the basis of this information, the respiratory therapist
should: - Answer-Maintain current settings

- A respiratory therapist is manually ventilating a patient
during a cardiopulmonary resuscitation attempt. An arterial
blood gas is drawn and the results are as follows:
pH: 7.27
PaCO2: 38 mmHg
HCO3: 17 mEq/L
PaO2: 44 mmHg
Based on this information, the respiratory therapist should
do which of the following? - Answer-Ensure that the
manual resuscitator is connected to an oxygen source
- A COPD patient is brought to the ED after several days
of increasing respiratory distress. Baseline blood gases
are drawn and the patient is placed on oxygen at 2 LPM
via nasal cannula. Data from the original and a
subsequent arterial blood sample are as follows:
Room Air Sample
pH: 7.23
, 4|Page
PaCO2: 82 mmHg
HCO3: 33 mEq/L
PaO2: 49 mmHg
2L nasal O2
pH: 7.33
PaCO2: 66 mmHg
HCO3: 34 mEq/L
PaO2: 54 mmHg
Based on the above information, the respiratory therapist
should: - Answer-Increase the oxygen flow to 3L/min and
continue to monitor.
- A 16-year-old female has just been admitted to the ED
following a bicycling accident. She is receiving
supplemental oxygen via nonrebreathing mask. While
standing at the bedside, the respiratory therapist notes the
onset of ataxic breathing. Which of the following should
the therapist do? - Answer-Begin manual ventilation
