• Question 141:

  "You are dispatched to a 70-year old male who is complaining of chest pain, and has a history of cardiac problems. If you assist in the administration of nitroglycerin, what is the maximum dosage to be given, without additional medical direction? "

  A. 2 tablets

  B. 3 tablets

  C. 4 tablets

  D. 5 tablets

  Correct Answer: B

  The maximum dosage amount is three tablets, or sprays, without additional medical direction.

• Question 142:

  "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

  Correct Answer: B

  The Tricuspid Valve is located BETWEEN the RIGHT ATRIUM and RIGHT VENTRICLE

• Question 143:

  "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

  Correct Answer: B

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

• Question 144:

  "What are the two lower chambers of the heart called? "

  A. Ventricles

  B. Atriums

  C. Bronchi

  D. Orbits

  Correct Answer: A

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

• Question 145:

  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.

  Correct Answer: C

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

• Question 146:

  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.

  Correct Answer: B

  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 147:

  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 AED.

  D. Patients usually describe cardiac pain as localized and moderately severe.

  Correct Answer: A

  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 148:

  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

  Correct Answer: A

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

• Question 149:

  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.

  Correct Answer: D

  Almost all documented cases of inappropriate shocks have been attributed to human error, such as using the AED in a moving vehicle or operating it on a patient with a pulse.

• Question 150:

  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.

  Correct Answer: C

  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.
