Question No : 1
"You are dispatched to a 65-year old male who is complaining of severe chest pain, and has a history of cardiac problems.
What is the primary role of medical direction in this scenario? "

正解:
Explanation:
Medical direction's primarily role is to authorize the delivery of interventions to the patient by the EMT.

Question No : 2
"In the heart, which valve is located between the right atrium and right ventricle?"

正解:
Explanation:
The Tricuspid Valve is located BETWEEN the RIGHT ATRIUM and RIGHT VENTRICLE

Question No : 3
"What are the two lower chambers of the heart called? "

正解:
Explanation:
The lower chambers of the heart (left, and right) are both called the "verticles".

Question No : 4
You should apply the AED pads to your patient when he

正解:
Explanation:
An AED should only be applied when the patient does not have a pulse nor respirations.

Question No : 5
The left atrium:

正解:
Explanation:
Pulmonary veins return oxygen-rich blood from the lungs to the left atrium, where it is sent to the left ventricle and pumped to the rest of the body.

Question No : 6
Which statement about the assessment of a patient with cardiac compromise is correct?

正解:
Explanation:
It is impossible to determine the actual degree of tissue damage in the field, so the purpose of the focused assessment is to gather information for the receiving facility. You should always ask about medications; it is the M of SAMPLE. The focused history has nothing to do with AED use. Cardiac pain has all sorts of presentations, making it difficult to differentiate from other conditions.

Question No : 7
Research shows that most of the cases of inappropriately delivered shocks from an AED have been caused by:

正解:
Explanation:
Almost all documented cases of inappropriateshocks have been attributed to human error,such as using the AED in a moving vehicle oroperating it on a patient with a pulse.

Question No : 8
Where does blood travel when it leaves the right ventricle of the heart?

正解:
Explanation:
Oxygen-poor blood arrives in the right atrium and is pumped out through the right ventricle via the pulmonary arteries, to the lungs

Question No : 9
A 64-year-old female has just collapsed in cardiac arrest. You are alone. After your initial assessment, you should give two ventilations, then:

正解:
Explanation:
While there is limited information that people in extended periods of cardiac arrest may benefit from CPR before defibrillation, overwhelming information indicates that defibrillating very early in a “fresh” arrest situation will provide the best opportunity for correcting the most common cause of cardiac arrest―ventricular fibrillation.

Question No : 10
Which chamber of the heart pumps oxygen-rich blood out to the body tissues?

正解:
Explanation:
Oxygen-rich blood reaches the left atrium from the lungs via the pulmonary veins; then, the left ventricle pumps it out to the rest of the body.

Question No : 11
Which patient is showing signs and symptoms of cardiac compromise?

正解:
Explanation:
This woman shows classic signs of cardiac compromise: dull chest pain, sudden onset of sweating, and difficulty breathing.

Question No : 12
Patients commonly describe heart attack pain as which of the following characteristic?

正解:
Explanation:
Myocardial pain is often difficult to determine because it can take on many different characters; however, patients most commonly (over 40% of the time) describe the pain of a myocardial infarction as a crushing, squeezing, pressure that radiates outward to the arms and upper back.

Question No : 13
Which heart rhythm often converts to ventricular fibrillation?

正解:
Explanation:
Ventricular tachycardia often converts to ventricular fibrillation, a life-threatening heart rhythm that the AED is designed to correct.

Question No : 14
Your patient is a 62-year-old man with a history of heart disease. He is experiencing chest pain. Your first action should be to:

正解:
Explanation:
Your first action would be to administer oxygen and place the patient in a comfortable position; next, if not contraindicated, you would request permission to administer nitroglycerin. You should first obtain a set of vital signs to ensure he is not in cardiogenic shock. Never put defibrillator pads onto a consciouspatient with a pulse; this procedure is contraindicated. AED pads are not serving the same function as the electrodes used by ALS providers to monitor the heart rhythm.

Question No : 15
A 45-year-old male patient is experiencing chest discomfort. After placing him in his position of comfort, your next action should be to:

正解:
Explanation:
There is no information to indicate that the patient requires ventilatory support. Any patient experiencing chest discomfort should receive the highest possible concentration of oxygen.
