1

a life-threatening condition that occurs when arterial blood flow and oxygen delivery to tissues and cells are inadequate

shock

2

what are the four main categories of shock?

*hypovolemic
*distributive
*obstructive
*cardiogenic

3

what are the subcategories of distributive shock

*neurogenic
*septic
*anaphylactic

4

the most common type of shock; condition that occurs when the volume of extracellular fluid is significantly diminished, primarily because of a loss or reduction in blood or plasma

hypovolemic shock

5

shock that occurs when fluid in the circulatory system does not facilitate effective perfusion of the tissue

distributive shock

6

shock that results from an insult to the vasomotor center in the medulla of the brain or to the peripheral nerves that extend from the spinal cord to the blood vessels

neurogenic shock

7

shock associated with overwhelming bacterial infections

septic shock

8

severe allergic reaction that occurs after exposure to a substance to which a person is extremely sensitive

anaphylactic shock

9

shock that occurs when the heart or great vessels are compressed

obstructive shock

10

shock that occurs when contraction of the heart is ineffective and cardiac output is reduced

cariogenic shock

11

first stage of shock, during which several physiologic mechanisms attempt to stabilize the spiraling consequences of shock

compensation shock

12

stage in shock that occurs as compensatory mechanisms fail and the client's condition spirals downward into cellular hypoxia, coagulation defects, and cardiovascular changes

decompensation stage

13

stage in shock that occurs when significant numbers of cells and organ systems become damaged and the client to longer responds to medical interventions

Irreversible stage

14

What are the three diagnostic measurements used when monitoring clients in shock?

*arterial blood gas
*central venous pressure
*pulmonary artery pressure

15

What are the three medical approaches for treating shock?

*IV fluid therapy
*vasopressor drug therapy
*mechanical devices that restore blood circulation to cells

16

What are the two types of disasters?

*natural
*human

17

What are the four types of natural disasters?

*earthquakes
*floods
*wild fires
*storms

18

what are the three categories of intentional human disasters?

*bombings
*biologic diasasters
*chemical disasters

19

What are three high-priority biologic agents used in bioterrorism warfare?

*anthrax
*botulism
*smallpox

20

what is the preferred antibiotic to treat anthrax?

*cipro
*levaquin

21

what is the treatment for botulism ?

botulinum antitoxin

22

examples of extremely toxic chemicals?

*nerve agents
*cyanide
*respiratory toxins
*blistering agents

23

Organophosphate compounds that cause fatal consequences by inhibiting acetylcholinesterase

nerve agents

24

what are the triage categories?

*immediate
*delayed
*minimal
*expectant

25

life threatening but survivable if rapid medical attention is provided; color tag is red

immediate triage

26

serious but stable enough to survive if treatment is delayed 6-8 hours; color tag is yellow

delayed triage

27

minor injuries that can wait longer for treatment; green tag color

minimal triage

28

soon to die; lack of spontaneous respirations after opening the airway; color tag is black

expectant triage
