An adult patient is receiving mechanical ventilation with a PEEP setting of 10
cmH2O. The physician has requested that you increase the setting to 14 cmH2O.
After making the adjustment, there is a rapid drop in the patient's blood pressure
and a significant increase in heart rate. Which of the following actions should you
take?
A. Increase the FiO2 by 10%
B. Lower the PEEP back to 10 cmH2O
C. Administer sodium bicarb
D. Obtain a stat EKG - ANSWERS-B
,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 - ANSWERS-D
A patient in the ICU is receiving positive pressure ventilatory support but appears

secretions?
A. An increased tidal volume
B. A decreased inspiratory time
C. A decreased plateau pressure
D. A decreased peak pressure - ANSWERS-D
A 176 lb male patient is intubated and receiving volume control A/C ventilation
with the following settings: FiO2 of 40%, Rate of 12/min, and Tidal Volume of 550
mL. An ABG was analyzed and the following results were obtained:
ABG Results and Ventilator Settings
pH 7.39
PaCO2 37 mmHg
HCO3- 23 mEq/L
PaO2 107 mmHg
Spontaneous Tidal Volume 180 mL
Spontaneous Rate 37/min
Vital Capacity 550 mL
MIP/NIF -12 cm H2O
Which of the following would you recommend?
A. Place the patient on a 40% T-piece and monitor closely B. Switch the patient to
SIMV at a rate of 5/minute
C. Place the patient on CPAP and monitor closely
