, Question 9
During an EMS call, you should take standard precautions:
A. immediately after completion of your primary assessment.
B. after it has been determined that the patient is bleeding.
C. before you load the patient into the ambulance.
D. before exiting the ambulance and before actual patient contact.
Correct Answer
D. before exiting the ambulance and before actual patient contact.
Question 10
In which of the following patients would the head tilt-chin lift maneuver be the MOST
appropriate method of opening the airway?
A. A 37-year-old female who is found unconscious in her bed
B. A 45-year-old male who is semiconscious after falling 20 feet
C. A 24-year-old male who is found unconscious at the base of a tree
D. A 50-year-old male who is unconscious following head trauma
Correct Answer
A. A 37-year-old female who is found unconscious in her bed
Question 11
A ventilation/perfusion (V/Q ratio) mismatch occurs when:
A. a disruption in blood flow inhibits the exchange of oxygen and carbon dioxide in
the lungs, even though the alveoli are filled with fresh oxygen.
B. ventilation is compromised, resulting in the accumulation of carbon dioxide in the
bloodstream, alveoli, and the tissues and cells of the body.
C. ventilation is inadequate due to a traumatic injury or medical condition, which
results in an impairment in pulmonary gas exchange.
D. a traumatic injury or medical condition impairs the body's ability to effectively
bring oxygen into the lungs and remove carbon dioxide from the body.
Correct Answer
A. a disruption in blood flow inhibits the exchange of oxygen and carbon dioxide in
the lungs, even though the alveoli are filled with fresh oxygen.
