Deoxygenated blood from the body returns to the:
right atrium
right ventricle
left atrium
left ventricle
Which of the following blood vessels transports oxygenated blood?
Superior vena cava
Pulmonary arteries
Inferior vena cava
Pulmonary veins
The electrical impulse generated by the heart originates in the:
bundle of His
coronary sinus
sinoatrial node
atrioventricular node
In contrast to the sympathetic nervous system, the parasympathetic nervous system:
prepares the body to handle stress
causes an increase in the heart rate
slows the heart and respiratory rates
dilates the blood vessels in the muscles
The right coronary artery supplies blood to the:
left ventricle and inferior wall of the right atrium
right ventricle and inferior wall of the left ventricle
right atrium and posterior wall of the right ventricle
left ventricle and posterior wall of the right ventricle
The iliac arteries immediately subdivide into the:
femoral arteries
peroneal arteries
anterior tibial arteries
posterior tibial arteries
Narrowing of the coronary arteries caused by a buildup of fatty deposits is called:
angina pectoris
arteriosclerosis
acute ischemia
atherosclerosis
Angina pectoris occurs when:
a coronary artery is totally occluded by plaque
myocardial oxygen demand exceeds supply
one or more coronary arteries suddenly spasm
myocardial oxygen supply exceeds the demand
The MOST common reason that many people experiencing AMI do not seek immediate medical attention is because they:
are elderly
are in denial
cannot afford it
do not trust EMTs
When documenting a patient’s description of his or her chest pain or discomfort, the EMT should:
use medical terminology
use the patient’s own words
underline the patient’s quotes
document his or her own perception
Which of the following signs is commonly observed in patients with right-sided heart failure?
Labored breathing
Dependent edema
Pulmonary edema
Flat jugular veins
A dissecting aortic aneurysm occurs when:
all layers of the aorta suddenly contract
a weakened area develops in the aortic wall
the inner layers of the aorta become separated
the aorta ruptures, resulting in profound bleeding
Upon arriving at the residence of a patient with a possible cardiac problem, it is MOST important to:
assess the scene for potential hazards
determine if you need additional help
request a paramedic unit for assistance
gain immediate access to the patient
Which of the following medications is commonly given to patients with chest pain to prevent blood clots from forming or getting bigger?
Furosemide (Lasix)
Aspirin
Oxygen
Metoprolol (Toprol)
Which of the following statements regarding nitroglycerin is correct?
The potency of nitroglycerin is increased when exposed to light
A maximum of five nitroglycerin doses should be given to a patient
Nitroglycerin should be administered between the cheek and gum
Nitroglycerin usually relieves anginal chest pain within 5 minutes
Most patients are instructed by their physician to take up to _______ doses of nitroglycerin before calling EMS
two
three
four
five
When preparing to obtain a 12-lead ECG, the LL and RL electrodes should be placed:
on the lower abdomen
anywhere on the arms
on the thighs or ankles
on either side of the chest
The AED is MOST advantageous to the EMT because:
it is lightweight, easy to use, and safe for the EMT who is using it
it delivers prompt defibrillation to patients with ventricular fibrillation
its use does not require the presence of advanced life support personnel
it delivers an unlimited number of shocks with the same amount of energy
Prior to attaching the AED to a cardiac arrest patient, the EMT should:
contact medical control
dry the chest if it is wet
perform CPR for 30 seconds
assess for a pulse for 20 seconds
Cardiogenic shock following AMI is caused by:
decreased pumping force of the heart muscle
a profound increase in the patient’s heart rate
hypovolemia secondary to severe vomiting
widespread dilation of the systemic vasculature
