RATED A+.
C&S TMC
Ace your preparation for the C&S TMC Exam by sharpening your
knowledge of advanced respiratory care concepts, disease
management, mechanical ventilation, and clinical decision-
making. This exam is ideal for respiratory therapy students
progressing toward success on the NBRC TMC credentialing
exam.

ordered for a 7 year old asthmatic child. After verifying the
order in the pt's medical record, the RT should ......
ANSWER ....... Assess pt and administer therapy as
ordered

...... Answer ....... 3 (mouth breathing-yes. Rapid deep
inspiration-no. Inspiratory pause-yes. Pursed-lip
breathing-yes)
Which of the following represents a primary indication for ET
instillment of surfactant? ...... ANSWER .......
Prophylactically for neonates <24 weeks gestational
age
All of the following are true regarding He/O2 therapy EXCEPT:
...... ANSWER ....... It has been shown to stimulate deep
breathing
Which of the following are acceptable alterations in a pt's
status during weaning trials? ...... ANSWER ....... 1 (An
increase in the PaCO2 of 3 mmHg-YES, An increase in the

The RT has been called to assess a 42 year old male pt who
is being mechanically ventilated via volume neb. Upon
entering the room, the therapist finds an agitated pt in
obvious respiratory distress. The therapist observes that the
SpO2 is 89% and the end-tidal CO2 is 52 mmHg. The
respiratory mechanics waveform is shown to the right.
Which of the following do you recommend? ...... ANSWER
....... Suction the patient
A 60 yr old 70 kg male pt is being MV via volume ventilator.
Vent settings are: SIMV; rate 14/min; Vt 525 mL; FiO2 0.70;
PEEP 10 cm H2O. ABG results on these settings are: pH
7.39, PaO2 82, PaCO2 43, HCO3 25. Over the last hours, the
pt's BP has decreased from 120/76 mmHg to 100/60 mmHg.
Respiratory mechanics has been initiated. The pressure and
flow curves are shown on the right. The most appropriate
action is: ...... ANSWER ....... Increasing the inspiratory
flow rate
After initiating MV in the AC mode for an adult male pt, the
RT observes that the pt is agitated and having difficulty
cycling the vent. Which of the following should the RT do?
...... ANSWER ....... Increase the sensitivity setting
