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?

C. 10 cm H20
D. 12 cm H2O Answer: B
⫸ The flow waveform that is most appropriate for a patient with high
Raw is which of the following?
A. Rectangle
B. Descending
C. Ascending
D. Exponential Answer: B

B. 1.4:1
C. 1.7:1
,D. 2:1 Answer: B
⫸ What flow rate is necessary to deliver a Vt 500 mL at a rate of 15
breaths/min with an I:E ratio of 1:3?
A. 30 L/min
B. 35 L/min
C. 40 L/min
D. 45 L/min Answer: A

m2 and a body temperature of 40 degrees C is which of the
following?
A. 8.2 L/min
B. 9.6 L/min
C. 10.6 L/min
D. 11.7 L/min Answer: D
⫸ A 5-foot 1-inch tall female patient receiving PSV 6 cm H2O is
showing signs of accessory muscle use and is exhaling a Vt of 220
mL at a rate of 28 breaths/min. The most appropriate action at this
time is which of the following?
A. Adjust the FiO2
, B. Increase the set flow rate
C. Increase the PSV to 10 cm H2O
D. Adjust the flow cycling percent Answer: C
⫸ 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?
