Quiz 7 (Ch 17 and 18)

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.

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.

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.

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.

A patient who is possibly experiencing a stroke is NOT eligible for thrombolytic (fibrinolytic) therapy if he or she:

• has had a prior heart attack.

• is older than 60 years of age.

• has a GCS score that is less than 8.

• has bleeding within the brain.

A patient with an altered mental status is:

• completely unresponsive to all forms of stimuli.

• typically alert but is confused as to preceding events.

• usually able to be aroused with a painful stimulus.

• not thinking clearly or is incapable of being aroused.

Muscle control and body coordination are controlled by the:

• cerebrum.

• cerebellum.

• brain stem.

• cerebral cortex.

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 MOST accurately describes the cause of an ischemic stroke?

• Blockage of a cerebral artery

• Acute atherosclerotic disease

• Rupture of a cerebral artery

• Narrowing of a carotid artery
