Sample Questions

1.
A patient with Duchenne’s muscular dystrophy requires an intermittent short-term therapy to maintain alveolar ventilation. The patient is not a candidate for aggressive mechanical ventilation as provided through an artificial airway. Which of the following would be the most appropriate treatment for this patient?
A)
Manual resuscitator
B)
Negative-pressure ventilator
C)
Volume ventilator
D)
Pressure ventilator

2.
A patient in the ICU is on a volume ventilator. The nurse recognizes that which of the following are true for this type of ventilator? Select all that apply.
A)
Peak inspiratory pressure varies from breath to breath and must be monitored closely.
B)
Amount of pressure depends on patient’s lung compliance and patient-ventilator resistance factors.
C)
The device fits like a tortoise shell, forming a seal over the chest.
D)
Exhaled tidal volume must be monitored closely.
E)
Volume varies based on changes in resistance or compliance.
F)
Small tidal volumes are used at frequencies greater than 100 breaths/minute.

3.
A patient has recently arrived in the ICU following cardiac arterial bypass graft surgery and has not yet emerged from anesthesia. He requires full ventilatory support. Which ventilation mode should the nurse use for this patient?
A)
Pressure support ventilation mode
B)
Synchronized intermittent mandatory ventilation mode
C)
Pressure-controlled ventilation mode
D)
Assist-control mode

4.
A patient with acute respiratory distress syndrome (ARDS) requires mechanical ventilation but is at risk for barotrauma due to decreased lung compliance. Which mode of ventilation should the nurse use with this patient?
A)
Pressure support ventilation mode
B)
Synchronized intermittent mandatory ventilation mode
C)
Pressure-controlled ventilation mode
D)
Assist-control mode

5.
A patient with acute respiratory distress syndrome (ARDS) has been receiving ventilation in assist-control mode for the past 48 hours. The fraction of inspired oxygen (FiO2) is set to 70% and tidal volume is set to 15 mL/kg of body weight. What complication or complications should the nurse be most concerned about in this situation? Select all that apply.
A)
Barotrauma
B)
Oxygen toxicity
C)
Volutrauma
D)
Hypoxemia
