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

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

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

ventilation with PCV which of the following will occur?
A. Peak pressure will increase.
B. Peak pressure will decrease.

decided to switch the patient to PC-CMV. What set PIP will deliver 6 mL/kg
IBW?
A. 30 cm H2O
B. 35 cm H2O
C. 38 cm H2O
D. 43 cm H2O - ANSWER-A
The most appropriate initial settings for a 5-foot 4-inch tall female
postoperative patient with no lung disease would be which fo the following?
A. PC-CMV, PIP 35 cm H2O, f 20 breaths/min, PEEP +10 cm H2O
B. PC-SIMV, PIP 20 cm H2O, f 6 breaths/min, PEEP +8 cm H2O
C. VC-CMV, 450 mL, f 10 breaths/min, PEEP +5 cm H2O
D. VC-CMV, 700 mL, f 14 breaths/min, PEEP 0 cm H2O - ANSWER-C
A patient is ready to be changed from VC-IMV to PSV. The VC-IMV
settings were VT 450 mL, f 4 breaths/min, and PEEP +5 cm H2O. The
patient's PIP is 31 cm H2O, and Pplateau is 23 cm H2O. The initial PSV
setting for this patient should be which of the following?
A. 5 cm H2O
