Question 4

A swelling or enlargement of a part of an artery from weakening of the arterial wall.

Answer 4

aneurysm

Question 5

The part of the nervous system that regulates involuntary activities of the body such as heart rate, blood pressure, and digestion of food.

Answer 5

autonomic nervous system

Question 6

Compression of the heart as the result of buildup of blood or other fluid in the pericardial sac, leading to decreased cardiac output.

Answer 6

cardiac tamponade

Question 7

A state in which not enough oxygen is delivered to the tissues of the body, caused by the low output of blood from the heart.

Answer 7

cardiogenic shock

Question 8

Answer 8

compensated shock

Question 9

A blue skin discoloration that is caused by a reduced level of oxygen in the blood.

Answer 9

cyanosis

Question 10

The late stage of shock when the blood pressure is falling.

Answer 10

decompensated shock

Question 11

Loss of water from the tissues of the body.

Answer 11

dehydration

Question 12

A condition that occurs when there is widespread dilation of the small arterioles, small venues, or both.

Answer 12

distributive shock

Question 13

The presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area.

Answer 13

edema

Question 14

A balance of all systems of the body.

Answer 14

homeostasis

Question 15

A condition in which the internal body temp falls below 95 F.

Answer 15

hypothermia

Question 16

Shock caused by fluid or blood loss.

Answer 16

hypovolemic shock

Question 17

The ability of the heart muscle to contract.

Answer 17

myocardial contractility

Question 18

Circulatory failure caused by paralysis of the nerves that control the size of the blood vessels, leading to widespread dilation, seen in patients with spinal cord injuries.

Answer 18

neurogenic shock

Question 19

Shock that occurs when there is a block to blood flow in the heart or great vessels, causing an insufficient blood supply to the body’s tissues.

Answer 19

obstructive shock

Question 20

The flow of blood through body tissues and vessels.

Answer 20

perfusion

Question 21

A collection of fluid between the pericardial sac and the myocardium.

Answer 21

pericardial effusion

Question 22

The pro contraction pressure in the heart as the volume of blood builds up.

Answer 22

preload

Question 23

Shock caused by a sudden, temporary reduction in the blood supply to the brain that causes fainting.

Answer 23

psychogenic shock

Question 24

A blood clot that breaks off from a large vein and travels to the blood vessels of the lung, causing obstruction of blood flow.

Answer 24

pulmonary embolism

Question 25

The difference between the systolic and diastolic pressures.

Answer 25

pulse pressure

Question 26

Developing a sensitivity to a substance that initially caused no allergic reactions.

Answer 26

sensitization

Question 27

Shock caused by severe infection, usually by bacteria.

Answer 27

septic shock

Question 28

shock
