left ventricle.
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 electrical impulse generated by the heart originates in the:

A 49-year-old male presents with an acute onset of crushing chest pain and diaphoresis. You should:
administer up to 324 mg of baby aspirin.
administer up to three doses of nitroglycerin.
obtain vital signs and a SAMPLE history.
assess the adequacy of his respirations.
You and your partner arrive at the scene of a middle-aged man who collapsed about 5 minutes ago. He is unresponsive, apneic, and pulseless. Bystanders are present, but have not provided any care. You should:
begin high-quality CPR and apply the AED as soon as possible.
have your partner perform CPR while you question the bystanders.
perform two-rescuer CPR for 5 minutes and request ALS backup.
immediately apply the AED pads and analyze his cardiac rhythm.
The only vein(s) in the body that carry oxygenated blood is/are the:
external jugular veins.
subclavian veins.
pulmonary veins.
inferior vena cava.
In general, a maximum of _____ dose(s) of nitroglycerin is/are given for any one episode of chest pain.

What is the function of the left atrium?
It ejects oxygenated blood into the aorta.
It receives oxygenated blood from the lungs.
It receives blood from the pulmonary arteries.
It receives oxygenated blood from the vena cava.
When an electrical impulse reaches the AV node, it is slowed for a brief period of time so that:
blood can pass from the atria to the ventricles.
blood returning from the body can fill the atria.
the impulse can spread through the Purkinje fibers.
the SA node can reset and generate another impulse.
Major risk factors for AMI include all of the following, EXCEPT:
hypoglycemia.
hypertension.
diabetes mellitus.
elevated cholesterol.
The three major parts of the brain are the:
cerebellum, medulla, and occiput.
brain stem, midbrain, and spinal cord.
midbrain, cerebellum, and spinal cord.
cerebrum, cerebellum, and brain stem.
The MOST significant risk factor for a hemorrhagic stroke is:
severe stress.
hypertension.
heavy exertion.
diabetes mellitus.
Which of the following conditions would be the LEAST likely to mimic the signs and symptoms of a stroke?
Hypoglycemia
Hypovolemia
A postictal state
Intracranial bleeding
Which of the following MOST accurately describes what the patient will experience during the postictal state that follows a seizure?
Hyperventilation and hypersalivation
A rapidly improving level of consciousness
Confusion and fatigue
A gradually decreasing level of consciousness
When caring for a patient with documented hypoglycemia, you should be MOST alert for:
a seizure.
an acute stroke.
violent, explosive diarrhea.
a febrile convulsion.
Which of the following conditions would MOST likely affect the entire brain?
Blocked cerebral artery in the frontal lobe
Reduced blood supply to the left hemisphere
Ruptured cerebral artery in the occipital lobe
Respiratory failure or cardiopulmonary arrest
The most basic functions of the body, such as breathing, blood pressure, and swallowing, are controlled by the:
brain stem.
cerebrum.
cerebellum.
cerebral cortex.
Which of the following is a metabolic cause of a seizure?
Poisoning
Head trauma
Brain tumor
Massive stroke
Febrile seizures:
often result in permanent brain damage.
are also referred to as absence seizures.
are usually benign but should be evaluated.
occur when a child's fever rises slowly.
You are dispatched to a residence for a 66-year-old male who, according to family members, has suffered a massive stroke. Your primary assessment reveals that the patient is unresponsive, apneic, and pulseless. You should:
assess the patient for a facial droop and hemiparesis.
initiate CPR and attach an AED as soon as possible.
obtain a blood glucose sample to rule out hypoglycemia.
perform CPR for 5 minutes before applying the AED.
