Flashcards in Shock Chpt. 10 Deck (27):
1

The force or resistance against which the heart pumps

Afterload

2

Severe shock caused by an allergic reaction

Anaphylactic shock

3

An unusual or exaggerated allergic reaction to foreign protein or other substances

Anaphylaxis

4

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

Aneurysm

5

The part of the nervous system that regulates involuntary functions, such as heart rate, blood pressure, digestion, and sweating

Autonomic nervous system

6

Shock caused by inadequate function of the heart, or pump failure.

Cardiogenic shock

7

The early stage of shock, in which the body can still compensate for blood loss.

Compensated Shock

8

Bluish color of the skin resulting from poor oxygenation of the circulation blood

Cyanosis

9

The late stage of shock when blood pressure is falling

Decompensated shock

10

Loss of water from the tissues of the body.

Dehydration

11

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

Distributive shock

12

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

Edema

13

A balance of all systems of the body.

Homeostasis

14

A condition in which the internal body temperature falls below 95°F (35°C), usually as a result of prolonged exposure to cool or freezing temperatures.

Hypothermia

15

Shock caused by fluid or blood loss.

Hypovolmic Shock

16

The final stage of shock, resulting in death

Irreversible Shcok

17

The ability of the heart muscle to contract.

Mycardial contractility

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.

Neurogenic shock

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.

obstructive shock

20

Circulation of blood within an organ or tissue in adequate amounts to meet the cells' current needs.

Perfusion

21

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

Preload

22

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

Psychogenic shock

23

Developing a sensitivity to a substance that initially caused no allergic reaction

Sensitization

24

Shock caused by severe infection, usually a bacterial infection.

Septic shock

25

A condition in which the circulatory system fails to provide sufficient circulation to enable every body part to perform its function; also called hypoperfusion.

Shock

26

circular muscles that encircle and, by contracting, constrict a duct, tube, or opening.

Sphincters

27

Fainting

Syncope
