MECHANICAL VENTILATION TEST 2 EXAMS
SET 2026 FULL QUESTIONS AND ANSWERS
GRADED A+.
⫸ A 5' 7" tall female multiple trauma patient was being managed on
VC-CMV, f 12 breaths/min, Vt 640 mL, PEEP +5 cm H2O, FiO2
60%, and a constant waveform for the past 24 hours. Currently, PIP is
45 cm H2O, Pplateau is 38 cm H2O, and the patient has been
diagnosed with acute respiratory distress syndrome. The respiratory
therapist wants to switch the patient to PC-CMV. The initial pressure
setting to target the appropriate Vt for this patient is which of the
following?
A. 10 cm H2O
B. 20 cm H20
C. 38 cm H20
D. 45 cm H20 Answer: B
⫸ How is pressure support ventilation cycled?
A. Flow
B. Pressure
C. Volume
D. Time Answer: A
,⫸ A patient has recently been diagnosed with obstructive sleep
apnea. The most appropriate treatment includes which of the
following?
A. Pressure support ventilation (PSV)
B. Noninvasive positive pressure ventilation (NIV)
C. Continuous positive airway pressure (CPAP)
D. Pressure-controlled continuous mandatory ventilation (PC-CMV)
Answer: C
⫸ Partial ventilatory support can be provided by which of the
following ventilator modes?
1. Pressure-controlled continuous mandatory ventilation (PC-CMV)
set rate 8 breaths/min
2. Volume-controlled intermittent mandatory ventilation (VC-IMV)
set rate 4 breaths/min
3. Pressure-controlled intermittent mandatory ventilation (PC-IMV)
set rate 10 breaths/min
4. VC-MMV set Ve8 L/min
A. 1 and 2 only
B. 2 and 3 only
C. 2 and 4 only
D. 3 and 4 only Answer: C
, ⫸ What type of breath occurs when the ventilator controls the
timing, tidal volume, or inspiratory pressure?
A. Assisted
B. Mandatory
C. Spontaneous
D. Controlled Answer: B
⫸ During volume control ventilation a patient's airway resistance
increases. This change will cause which of the following to occur?
A. Increase in delivered volume
B. Increase in peak airway pressure
C. Decrease in plateau pressure
D. Decrease in peak airway pressure Answer: B
⫸ A hemodynamically unstable patient being ventilated in the
volume-controlled continuous mandatory ventilation (VC-CMV)
mode is triggering inspiration at a rate of 25 breaths/min and has the
following arterial blood gas results: pH 7.50, partial pressure of
carbon dioxide (PaCO2) 30 mm Hg, partial pressure of oxygen
(PaO2) 98 mm Hg, arterial oxygen saturation (SaO2) 100%,
bicarbonate (HCO3) 24 mEq/L. The respiratory therapist should
perform which of the following?
