PREP: QUESTIONS AND ANSWERS 2026
FINAL PAPER.
⫸ How many variables can a ventilator control at one time? Answer:
1
⫸ An increase in airway resistance during volume-controlled
ventilation will have which of the following effects? Answer: Pressure
increase
⫸ An increase in airway resistance during pressure-targeted
ventilation will have which of the following effects? Answer: Volume
decrease
⫸ The ventilator variable that begins inspiration is which of the
following? Answer: Trigger
⫸ A patient who has been sedated and paralyzed by medications is
being controlled by the ventilator. The set rate is 15 breaths/min. How
many seconds does it take for inspiration and expiration to occur
Answer: 4 sec
⫸ The limit variable set on a mechanical ventilator will do which of
the following? Answer: Control the maximum value allowed
, ⫸ The variable that a ventilator uses to end inspiration is known as
which of the following? Answer: Limit
⫸ Which maneuver will maintain air in the lungs at the end of
inspiration, before the exhalation valve opens? Answer: Inspiratory
hold
⫸ A patient who has a decrease in lung compliance due to acute
respiratory distress syndrome during volume-limited ventilation will
cause which of the following? Answer: Increased peak pressure
⫸ The formula used for the calculation of static compliance (CS) is
which of the following? Answer: Tidal volume/(plateau pressure -
EEP)
⫸ How many time constants are necessary for 95% of the tidal
volume (VT) to be delivered from a mechanical ventilator? Answer: 3
⫸ Calculate the static compliance (CS), in mL/cm H2O, when PIP is
26 cm H2O, plateau pressure (Pplateau) is 19 cm H2O, baseline
pressure is 5 cm H2O, and exhaled tidal volume (VT) is 425 mL
Answer: 30
⫸ What type of ventilator increases transpulmonary pressure (PL) by
mimicking the normal mechanism for inspiration? Answer: Negative-
pressure ventilation (NPV
