8

_______ is the maximum pressure exerted by the left ventricle as it contracts.

Systolic blood pressure

9

Atherosclerosis can lead to a complete _______ of a coronary artery.

Occlusion

10

The lumen of an artery may be partially or completely blocked by the blood-clotting system due to a ________ that exposes the inside of the atherosclerotic wall.

Crack

11

Tissues downstream from a blood clot will suffer from a lack of oxygen. If blood is resumed in a short time, the ________ tissues will recover.

Ischemic

12

Risk factors for myocardial infarction include all of the following EXCEPT:

14

Angina pain may be felt in the:

30

18

An acute myocardial infarction is more likely to occur in the larger, thick-walled left ventricle, which needs more ________ than the right ventricle.

Blood and oxygen

19

Which of the following statements regarding CHF is FALSE?

Stridor is a common lung sound heard on exam

20

Cardiogenic shock can occur within 24 hours of a(n):

Sudden death is usually the result of __________, in which the heart fails to generate an effective blood flow.

Cardiac arrest

22

Disorganized, ineffective quivering of the ventricles is known as:

Which of the following changes in heart function occur in patients with CHF?

Enlargement of the left ventricle

26

Physical findings of AMI include skin that is _________ because of poor cardiac output and the loss of percussion.
