NCLEX Mechanical Ventilation Questions and Answers Latest Version Already Passed
A nurse is caring for a patient on a mechanical ventilator and notices that the patient's peak inspiratory pressure has increased. Which of the following is the most likely cause?
a) Increased tidal volume
✔✔b) Obstruction in the airway
c) Decreased positive end-expiratory pressure (PEEP)
d) Decreased respiratory rate
A nurse is caring for a patient who is on a mechanical ventilator in the assist-control (AC) mode.The nurse notices that the patient’s respiratory rate is higher than the set rate, but the ventilator is still delivering the set tidal volume with each breath. What should the nurse do?
a) Increase the tidal volume
✔✔b) Nothing, this is expected in assist-control mode
c) Decrease the ventilator rate
d) Switch the ventilator mode to pressure support

A nurse is caring for a patient on a mechanical ventilator in the synchronized intermittent mandatory ventilation (SIMV) mode. What is the primary benefit of this mode for the patient?✔✔a) It allows the patient to breathe spontaneously between ventilator-delivered breaths
b) It delivers a constant positive pressure during inhalation
c) It assists the patient with every breath
d) It guarantees a set volume with every breath
A nurse is caring for a patient on a mechanical ventilator who has a decreased oxygen saturation level despite appropriate ventilator settings. What is the first action the nurse should take?✔✔a) Assess for a possible kink or obstruction in the endotracheal tube
b) Increase the tidal volume setting
c) Increase the PEEP setting
d) Adjust the respiratory rate to improve ventilation
A nurse is monitoring a patient on mechanical ventilation with a volume-controlled mode. The nurse is concerned about the risk of ventilator-associated lung injury (VILI). Which of the following interventions would be most appropriate?
a) Increasing the tidal volume
✔✔b) Using lower tidal volumes to minimize pressure on the lungs
