TMC Exam Questions and Answers
Graded A+
Romazicon (flumazenil) ✔✔-antidote for benzodiazepines such as
-GABA receptor antagonist
- It can treat drowsiness caused by sedatives following surgery or drug overdose.
Which of the following can be used to estimate the level of Hemoglobin? ✔✔RBC
-RBC X 3 = hemoglobin
with the use of pressure control the most important alarm is ✔✔low volume
-because the ventilator does not care about volume, the practitioner must.
The most important alarm on a volume-cycled ventilator would be ✔✔high pressure alarm
Which of the following would be most effective at resolving a humidity deficit for a patient who
is intubated with an 8.0-mm endotracheal tube ✔✔wick or concha
Which of the following would be most helpful for a patient with fixed upper airway obstruction?
,A. beta II agonist medication
B. heliox therapy
C. aerosolized epinephrine
D. corticosteroids ✔✔B. heliox therapy
Heliox therapy is most appropriate. Helium, when combined with oxygen, is less viscous than
pure oxygen or room air, which is made up mostly of nitrogen. This allows patients to breathe in
gases with less airway resistance.
-fixed obstruction means it cannot be resolved simply with bronchodilators or other immediate
methods.
which one should be treated first, ventilation or oxygenation ✔✔ventilation
the patient is over oxygenating AND hyperventilating
which one should you treat first? ✔✔over oxygenation
-To address over-oxygenation one can either change the PEEP or the FIO2. You will always
want to lower the FIO2 below 60% before changing PEEP.
ways to decrease CO2 ✔✔increase the Vt
,increase the rate
remove dead space
What would occur on a time-cycled ventilator with a fixed rate if the inspiratory flow rate were
increased?
A. increase in tidal volume
B. decrease in inspiratory time
C. decrease in tidal volume
D. increase in inspiratory time ✔✔A. increased in tidal volume
On a time-cycled ventilator inspiratory time is predetermined. So, if the flow rate is increased
while the mandatory rate is unchanged, the result would be an increase in tidal volume.
Which of the following is the most significant complication of bronchoscopy?
A. laryngospasms
B. hypotension
C. vagal nerve stimulation
D. coughing ✔✔A. laryngospasm
, -This tendency may be reduced by administering aerosolized Lidocaine or any other tissue
numbing agent prior to the procedure.
What is the respiratory therapist observing if monitoring the total amount of gas exhaled in 60
seconds after excluding dead space?
A. minute ventilation
B. dead space ventilation
C. alveolar minute ventilation
D. maximum voluntary ventilation ✔✔c. alveolar minute ventilation
Examining the breathing rate over a period of 60 seconds and multiplying it times the tidal
volume gives you minute ventilation. If deadspace is subtracted from that volume then what is
being observed is alveolar minute ventilation.
education and direction for the performance of positive expiratory pressure (PEP) therapy
✔✔Proper instructions for the use of a PEP therapy device includes "inhaling deeply and
exhaling actively".
equations to determine cardiac output ✔✔fick equation
