EMT 시험 - Test-Prep실제시험문제와 답 - 222문항

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? "

A.Medical direction serves no purpose
B.Give authorization for interventions
C.Talk to and calm the patient
D.Talk to the family and calm them

정답:
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?"

A.Bicuspid Valve
B.Tricuspid Valve
C.Aortic Valve
D.Pulmonic Valve

정답:
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? "

A.Ventricles
B.Atriums
C.Bronchi
D.Orbits

정답:
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

A.Complains of trouble breathing.
B.Appears confused and “out of it”.
C.Is pulseless and apneic.
D.Is unconscious and vomiting.

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

Question No : 5

The left atrium:

A.Receives blood from the veins of the body.
B.Receives blood from the pulmonary veins.
C.Pumps blood to the lungs.
D.Pumps blood to the body.

정답:
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?

A.You cannot determine the degree of cardiac damage in the field.
B.You should not ask patients about nitroglycerin or other drug use.
C.The purpose of the focused history is to determine whether to use the AE
D.Patients usually describe cardiac pain as localized and moderately severe.

정답:
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:

A.Mechanical interference.
B.Improperly charged batteries.
C.Malfunctioning electrodes.
D.Human error.

정답:
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?

A.To the pulmonary veins, then to the lungs
B.To the aorta, then out to the body
C.To the vena cava then to the left atrium
D.To the pulmonary arteries then to the lungs

정답:
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:

A.Analyze the rhythm, and deliver a shock if indicated.
B.Begin chest compressions for one minute.
C.Analyze the rhythm, and begin chest compressions.
D.Call medical control, and begin chest compressions.

정답:
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?

A.Right atrium
B.Right ventricle
C.Left atrium
D.*Left ventricle

정답:
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?

A.85-year-old man: difficulty breathing, high fever, rapid pulse
B.72-year-old woman: wheezing, labored breathing, tightness in throat
C.53-year-old woman: dull chest pain, sudden sweating, difficulty breathing
D.51-year-old man: headache, dizziness, gagging, chest pain

정답:
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?

A.Like “pins and needles”
B.Crushing or squeezing
C.Intermittent (comes and goes)
D.Less severe than indigestion

정답:
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?

A.Asystole
B.Ventricular tachycardia
C.Atrial fibrillation
D.Atrial tachycardia

정답:
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:

A.Place the pads for the automated external defibrillator on his chest.
B.Begin CPR while preparing the automated external defibrillator.
C.Ask him if he has taken his nitroglycerin, and if not, offer to assist him.
D.Place him in a comfortable position and administer high-flow oxygen.

정답:
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:

A.Ventilate the patient with a nonrebreather mask at 15 liters per minute.
B.Ventilate the patient with the bag-valve mask at 15 liters per minute.
C.Administer oxygen by nonrebreather mask at 15 liters per minute.
D.Administer oxygen by the nasal cannula at 6 liters per minute.

정답:
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.
