ventilatory support with a time-cycled, pressure-limited
ventilator at the following settings:
PIP 35 cm H2O
Rate 28
FIO2 0.4

not rise to the set pressure during each inspiration. Which of the
following is the most likely cause?
A. the pressure-limiting pop-off valve is set to low
B. internal flow rate is too high
C. rate is insufficient
D. set pressure exceeds the pressure capability of the ventilator
- correct answer- The correct answer is : A
A 31-week-gestional age infant has a respiratory rate of 30/min
and a heart rate of 70/min while breathing room air. Five
minutes after birth, the infant is acrocyanotic and has a weak

answer- The correct answer is : D

The correct answer is : C
A 38-week gestational age infant is to receive oxygen therapy by
a blender set at 100% with a heated large-volume nebulizer. To
ensure the delivery of the ordered FIO2, the respiratory
therapist should properly set the nebulizer FIO2 to
A. 100%
B. 50%
C. 0%
D. 21% - correct answer- The correct answer is : A
