TMC Mechanical Ventilation Practice Questions
and Answers 100% Correct
A 58-year-old female is receiving volume control A/C ventilation at a rate of 12/min with a tidal
volume of 450 mL. The FiO2 is set at 40% and her ABG results are as follows:
pH 7.35
PaCO2 44 torr HCO3 22 mEq/L BE 0
PaO2 91 torr SaO2 97%
Based on this information, you should recommend which of the following?
A. Decrease the minute ventilation
B. Discontinue mechanical ventilation
C. Administer IV bicarbonate
D. Maintain the current settings ✔✔ D

breathing asynchronously with the machine-delivered breaths. Which of the following
medications would you recommend?
A. Fluoxetine (Prozac)
B. Midazolam (Versed)
C. Dextroamphetamine (Dexedrine)
D. Cisatracurium (Nimbex) ✔✔ B
During the assessment of a 64-year-old patient who is receiving volume-controlled ventilation,
you note that the peak airway pressure has decreased from 36 to 19 cmH2O. There have been
no changes to the ventilator settings. Which of the following would you recommend?
A. Increase the volume setting until the pressure equals 36 cmH2O
B. Increase the flow setting until the pressure equals 36 cmH2O
C. Check for increased secretions and suction if needed
, D. Check the circuit for system leaks ✔✔ D
The physician has requested a mode of ventilation in which you can maintain a precise I:E ratio.
Which of the following modes would you select?
A. Synchronous Intermittent Mandatory Ventilation
B. Control Mode Ventilation
C. Assist-Control Ventilation
D. Pressure Support Ventilation ✔✔ B

the patient's airway resistance?
A. 5 cm H2O/L/sec
B. 15 cm H2O/L/sec
C. 30 cm H2O/L/sec
D. 60 cm H2O/L/sec ✔✔ B
