10) A TV reporter has been assigned to your ambulance for a ride-along. He is
doing a segment on the local EMS system for EMS Week. In your down time,
the reporter tells you that his wife was diagnosed with atherosclerosis. He is
unsure what this condition is and asks you to explain it to him. Your response
would be:
A) "Atherosclerosis affects the arteries of the heart and is caused by a heart
attack."
B) "The walls of the coronary arteries lose elasticity, which can lead to a heart
attack."
C) "The coronary arteries become damaged and narrowed by fat deposits."
D) "Atherosclerosis affects the veins in the body and is caused by untreated
high blood pressure."
C) "The coronary arteries become damaged and narrowed by fat deposits."
11) You are interviewing a patient whom you suspect has an acute coronary
syndrome. Which question is most appropriate initially?
A) "Are you having any pain in your chest?"
B) "Are you having any chest discomfort?"
C) "Does it hurt when I press on your chest?"
D) "Does your chest hurt when you breathe?"
B) "Are you having any chest discomfort?"
12) You have arrived at a residence to help another crew with a 62-year-old
woman who is complaining of fatigue, chest discomfort, and diaphoresis. The
EMTs on scene report that she has a history of hypertension from
atherosclerosis, for which she takes a blood pressure pill, and is also
prescribed nitroglycerin. She reports an allergy to aspirin. Vital signs are
pulse, 64; respirations, 16 breaths/min; blood pressure, 128/86 mmHg; and
SpO2, 97% on room air. Which of these statements made by your EMT partner
would require immediate correction on your part?
A) "I am not going to attach the AED, because the patient is conscious and has
a pulse."
B) "I am going to put the patient on high-concentration oxygen because she
has chest discomfort."
C) "I will contact medical direction for permission to administer the patient's
