Which of the following statements regarding positive-pressure ventilation is
correct?
Select one:
A. Unlike negative-pressure ventilation, positive-pressure ventilation does not
affect the esophageal opening pressure.
B. To prevent hypotension, the EMT should increase the rate and force of positive-
pressure ventilation.
C. With positive-pressure ventilation, more volume is required to have the same
effects as normal breathing.
D. Positive-pressure ventilation allows blood to naturally be pulled back to the
heart from the body. - correct-answer -C. With positive-pressure ventilation, more
volume is required to have the same effects as normal breathing.
Hypoxia is MOST accurately defined as:
Select one:
A. an increase in carbon dioxide in the blood.
B. a decrease in arterial oxygen levels.
C. inadequate oxygen to the tissues and cells.

D. high oxygen levels in the tissues and cells. - correct-answer -C. inadequate
oxygen to the tissues and cells.
Which of the following patients would MOST likely require insertion of an
oropharyngeal airway?
Select one:
A. A 51-year-old confused patient with severely labored respirations
B. A 64-year-old conscious patient with rapid and deep respirations
C. A 33-year-old semiconscious patient with reduced tidal volume
D. A 40-year-old unconscious patient with slow, shallow respirations - correct-
answer -D. A 40-year-old unconscious patient with slow, shallow respirations
Intrapulmonary shunting occurs when:
Select one:
A. blood coming from the right side of the heart bypasses nonfunctional alveoli
and returns to the left side of the heart in an unoxygenated state.
B. a decrease in respiratory rate and depth causes carbon dioxide accumulation in
the alveoli and an overall decrease in blood oxygen levels.
C. the presence of pulmonary surfactant causes a decrease in alveolar surface
tension, thus impairing the exchange of gases in the lungs.
D. any impairment in circulatory function causes a reduced ability for oxygen and
carbon dioxide to diffuse across the alveolar-capillary membrane. - correct-answer
-A. blood coming from the right side of the heart bypasses nonfunctional alveoli
and returns to the left side of the heart in an unoxygenated state.

Prior to applying a nonrebreathing mask to a patient, you must ensure that the:
Select one:
A. flow rate is set at 6 L/min.
B. patient has reduced tidal volume.
C. reservoir bag is fully inflated.
D. one-way valve is sealed. - correct-answer -C. reservoir bag is fully inflated.
While providing CPAP to a patient in severe respiratory distress, you note that his
heart rate has increased by 20 beats/min. He is conscious, but is no longer
following verbal commands. You should:
Select one:
A. remove the CPAP device and ventilate him with a bag-mask device.
B. decrease the amount of pressure that the CPAP device is delivering.
C. remove the CPAP device and apply oxygen by nonrebreathing mask.
D. increase the amount of pressure that the CPAP device is delivering. - correct-
answer -A. remove the CPAP device and ventilate him with a bag-mask device.
To select the proper size oropharyngeal airway, you should measure from the:
Select one:
A. center of the mouth to the posterior ear.
