Question:When assessing a patient on mechanical ventilation, you
discover absent breath sounds on one side and tracheal deviation. Which
complication of mechanical ventilation should you suspect?
A. Pneumonia
B. Oxygen toxicity
C. Auto-positive end-expiratory pressure
D. Tension pneumothorax
Ans: D
Question: A patient is receiving pressure-controlled, volume variable
mechanical ventilation. What is a disadvantage of this type of mechanical
ventilation?
A. The distending pressure of the lungs is limited.
B. Inspiration is terminated when a certain pressure is achieved.
C. It is associated with a risk of lung injury.
D. Minute ventilation volume is not guaranteed.
Ans: D
Question: Which finding is considered a manifestation of systemic
inflammatory response syndrome?
A. A white blood cell count of 11,500/mm3
B. A heart rate of 85 beats per minute
C. A partial pressure of carbon dioxide (PaCO2) of 26 mm Hg
D. A temperature of 96.8° F (36° C)
Ans: C

intervention decreases the risk of developing ventilator-associated
pneumonia?

A. Regular oral care
B. Use of the same suction catheter periodically
C. Keeping the patient flat in bed

Ans: A
Question: The nurse is caring for a patient after pulmonary artery
catheter insertion. Which complication may occur if the catheter
migrates?
A. Vasospasm
B. Cardiac tamponade
C. Pulmonary hypertension
D. Premature ventricular contractions
Ans: D
Question: In a patient with abdominal hypertension, what causes
inadequate ventilation?
A. Anatomical causes
B. Shunting
C. Muscular abnormalities
D. Partial airway obstruction
Ans: A

permissive hypercapnia. The physician orders arterial blood gas analysis
on this patient. Which arterial blood gas finding should you expect?
A. pH of 7.15
B. pH of 7.25
C. pH of 7.35
D. pH of 7.45
Ans: B
Question: Which mode of mechanical ventilation lets the patient breathe
at his or her own tidal volume?
A. Pressure control ventilation
