MECHANICAL VENTILATION TEST 2 EXAM
REVIEW 2026 FINAL PAPER COMPLETE
QUESTIONS AND ANSWERS.
⫸ A post-thoracic surgery patient currently receiving mechanical
ventilation on VC-CMV with 60% oxygen has the following arterial
blood gas: pH 7.45, PaCO2: 36 mmHg, PaO2: 68 mmHg. The
patient's peak inspiratory pressures are averaging 55 cm H20. The
ventilator mode that is most appropriate at this time is which of the
following?
A. PSV
B. VC-IMV with PEEP
C. PC-CMV with PEEP
D. MMV Answer: C
⫸ A 38-year-old female suffered a deceleration injury in an MVC.
She is alter and oriented but in respiratory distress. A portion of the
patient's right anterior chest wall is moving in a paradoxical motion.
Breath sounds are decreased on the right and the trachea is midline
and no pneumothorax was detected. ABG data reveal pH 7.48, PaCO2
31 mmHg, PaO2 63 mmHg, and HCO3 24 mEq/L. The respiratory
therapist should recommend which of the following therapies for this
patient at this time?
A. Mask CPAP with supplemental oxygen
B. Intubate and use VC-CMV with PEEP
,C. NIV with supplemental oxygen
D. Intubate and use PCIRV Answer: A
⫸ The physician requests that the respiratory therapist make a
recommendation for a patient with post polio complaints of increasing
daytime weakness. Her VC is 12 mL/kg and maximal inspiratory
pressure is -32 cm H2O. Her ABG on room air reveals pH 7.38,
PaCO2 46 mmHg, PaO2 74 mmHg, and HCO3 24 mEq/L. The
respiratory therapist should suggest which of the following?
A. Tracheostomy with PSV
B. Tracheostomy with VC-CMV
C. BiPAP via nasal mask at night
D. Full face mask CPAP with supplemental oxygen Answer: C
⫸ During a pressure-triggered breath in VC-CMV the pressure-time
curve on the graphic display does not rise smoothly and appears to be
somewhat concave in appearance. This indicates which of the
following?
A. Flow rate is inadequate
B. Rise time is set too slow
C. Overshoot on the pressure
D. Inspiratory time is too short Answer: A
,⫸ Every breath from the ventilator is time or patient triggered,
pressure targeted (limited), and time cycled. This describes which of
the following ventilator modes?
A. PAug
B. APRV
C. PCV
D. VC-IMV Answer: C
⫸ Pressure augmentation (Paug) may be beneficial for mechanically
ventilated patients with which of the following?
1. Noncardiogenic pulmonary edema
2. Acute respiratory Distress Syndrome
3. Postoperative upper abdominal surgery
4. Receiving heavy sedation and paralyzing agents
A. 1 and 2 only
B. 1 and 3 only
C. 2 and 4 only
D. 3 and 4 only Answer: B
⫸ The ventilator mode that allows the patient to breathe
spontaneously at two levels of positive pressure is known as which of
the following?
, A. CPAP
B. PAug
C. PRVC
D. APRV Answer: D
⫸ A patient is intubated and on PSV. The respiratory therapist
notices that inspiratory time has increased from 1 second to 2 seconds
consistently on every breath since last ventilator rounds. What should
be the first action the respiratory therapist should do to correct the
problem?
A. Change to the SIMV mode
B. Check the endotracheal tube cuff pressure
C. Increase the inspiratory flow setting
D. Suction and lavage the patient's airway Answer: B
⫸ When lung compliance decreases while a patient is receiving
mechanical ventilation with PCV which of the following will occur?
A. Peak pressure will increase.
B. Peak pressure will decrease.
C. Tidal volume will increase.
D. Tidal volume will decrease. Answer: D
