C&S TMC Exam 1
1. - An infant is being mechanically ventilated via a time-cycled, pressure-
lim- ited ventilator. Which of the following would occur if PEEP were
increased without a corresponding increase in peak pressure?: The tidal
volume would decrease
2. - A physician requests the respiratory therapist to assess the upper
airway function of a patient with a fenestrated tracheostomy tube. The
therapist should:: Remove the inner cannula, deflate the cuff, plug the
outer cannula
3. - 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
situa- tion?: The patient needs re-instruction regarding the SMI therapy
4. - 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?: Increase the sensitivity setting
5. - 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::
Maintain current settings
6. - A respiratory therapist is manually ventilating a patient during a
cardiopul- monary 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?: Ensure that the manual resuscitator is connected to an
oxygen source
7. - 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
PaCO2: 82 mmHg
HCO3: 33 mEq/L
PaO2: 49 mmHg
2L nasal O2
