This activity contains 27 questions.
The blanket term that refers to any kind of problem with the heart is:
heart attack.
cardiac compromise.
angina pectoris.
cardiac arrest.
If you are a single rescuer with an AED arriving at the scene of an unwitnessed arrest, you should:
begin CPR and wait for a second rescuer before using the AED.
ventilate and apply the AED without starting CPR.
perform CPR for two minutes (5 cycles), then apply the AED.
perform one cycle of 30:2 CPR, then apply the AED.
If your patient who regained a pulse after being defibrillated goes back into cardiac arrest while en route to the hospital, you should:
continue transport and defibrillate immediately.
stop the vehicle and defibrillate if indicated.
resume CPR and continue transport.
stop the vehicle, begin CPR, and contact medical control.
A common symptom in patients with cardiac compromise is an abnormal heart beat. A heart rate that is too slow is called:
tachycardia.
palpitation.
bradycardia.
hypotension.
After delivering your first shock with an AED, the patient is still pulseless, you should next:
contact medical control.
deliver an additional shock.
immediately transport, continuing CPR.
perform two minutes (5 cycles) of CPR, unless the patient wakes up.
Hypotension, or low blood pressure, in an adult is considered a systolic blood pressure of less than:
120 mmHg.
110 mmHg.
100 mmHg.
90 mmHg.
Which of the following is true regarding asystole?
It is caused by chaotic electrical activity in the heart muscle.
It is a "shockable" rhythm.
It is the primary electrical disturbance resulting in cardiac arrest.
The heart has ceased generating electrical impulses.
Common symptoms of a patient in cardiac compromise include:
difficulty breathing and chest pain.
warm, dry skin.
cool, dry skin.
all of the above.
Chaotic electrical activity originating from many sites in the heart is called:
V-tach.
PEA.
asystole.
V-fib.
One reason patients with cardiac compromise think they might have the "flu" is because the symptoms include:
fever.
a headache.
sweating with nausea.
a cough.
An example of a "shockable" rhythm -- that is, one for which defibrillation is effective -- is:
pulseless ventricular tachycardia.
asystole.
pulseless electrical activity.
all of the above.
Automated defibrillators that advise the EMT-Basic to press a button that delivers the defibrillation shock are called:
semiautomatic.
fully automatic.
manual.
semi-manual.
A contraindication to assisting the patient in taking nitroglycerin tablets is:
the patient complains of chest pain.
the systolic blood pressure is less than 100 mmHg.
the patient has a history of a previous heart attack.
the patient has already taken one nitroglycerin tablet.
The condition of excessive fluid buildup in the lungs because of the inadequate pumping of the heart is called:
myocardial infarction.
angina pectoris.
congestive heart failure.
coronary artery disease.
The condition known as atherosclerosis is caused by:
stiffening or hardening of the artery wall resulting from calcium deposits.
a buildup of fatty deposits on the inner walls of the arteries.
a blood clot completely blocking the blood flow in an artery.
an increased level of cholesterol in the blood, resulting in vasospasms.
A thrombus which has broken loose, moving with blood flow, is called a(n):
clot.
occlusion.
embolism.
thrombosis.
Chest pain caused by a narrowed coronary artery that cannot supply enough oxygen to a portion of the heart during exertion is called:
myocardial infarction.
congestive heart failure.
pulmonary edema.
angina pectoris.
Some risk factors for heart problems can be reduced by lifestyle changes. Some cannot be changed. A risk factor that cannot be changed is:
elevated blood levels of cholesterol.
hypertension.
cigarette smoking.
heredity.
A malfunction of the heart's electrical system will generally result in a(n):
aneurysm.
dysrhythmia.
thrombus.
occlusion.
A weakened section of an arterial wall that begins to dilate is known as a(n):
aneurysm.
thrombus.
embolism.
occlusion.
_______ AEDs use less power and may cause less damage to the patient's heart.
Monophasic
Biphasic
Automatic
Hemiphasic
The most important drug in the treatment of heart problems is:
nitroglycerin.
atropine.
oxygen.
adrenaline.
If the patient is not defibrillated within _______ minutes of a cardiac arrest, there is almost no chance for survival.
eight
ten
four
fifteen
Half of all cardiac arrest patients will initially have a _______ rhythm.
V-Tach
AF
PEA
VF
If a cardiac arrest occurs within two hours of the onset of symptoms, it is called (a):
sudden death.
cardiac ablation.
irreversible fatality.
rapid onset cardiac death (ROCD).
If a pediatric patient has a cardiac problem, it is most likely:
the result of respiratory distress.
congenital.
fatal.
related to poisoning.
If an AED analyzes a patient and finds pulseless electrical activity, how is it programmed to respond?
It will indicate "shock advised."
It will remain in the "analyze" mode.
It will indicate "no shock advised."
It will instruct the operator to "check the pads."
