Shock

Question 1

Shock (hypoperfusion)

Answer 1

Describes a state of collapse and failure of the cardiovascular system.

- body tries to compensate
- shock happened from medical and/or trama

Question 2

homeostasis

Answer 2

stable environment where all things are balanced and adequate

Question 3

perfusion

Answer 3

adequate oxygen supply to the cell
- systemic = full body

Question 4

what does perfusion look like?

Answer 4

• pink, warm, dry
• mental status = alert and oriented
• cap refill
• SPO2: 95-100%
• respiratory 12-20

Question 5

compensated shock

Answer 5

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

Question 6

anaphylaxis

Answer 6

An extreme, life-threatening, systemic allergic reaction that may include shock and respiratory failure.

Question 7

Anaphylactic shock

Answer 7

severe shock caused by an allergic reaction

Question 8

aneurysm

Answer 8

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

Question 9

Autonomic nervous system

Answer 9

the part of the nervous system that regulates the heart rate, blood pressure, and digestion of food.

Question 10

Cardiac tamponade

Answer 10

compression of the heart -> buildup of blood in the pericardial sac -> decrease cardiac output.

Question 11

Cardiogenic shock

Answer 11

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

- High colastrol
- heart attack

Question 12

Cyanosis

Answer 12

change in color (skin)

Question 13

decompensated shock

Answer 13

the late stage of shock when blood pressure is falling

Question 14

dehydration

Answer 14

loss of water from the tissues of the body

Question 15

distributive shock

Answer 15

a condition thatt occurs when there is widespread dilation of the small arterioles, small venules, or both

cant distribute blood.

Question 16

edema

Answer 16

abnormally amounts of fluid between cells in body tissue -> swelling

Question 17

hypovolemic shock

Answer 17

caused by plasma loss -> reduce tissue perfusion

Question 18

myocardial contractility

Answer 18

the ability of the heart muscle to contract

Question 19

neurogenic shock

Answer 19

circulatory failure caused by paralysis of the nerves that control the size of the blood vessels, -> dilation (spinal injury)

Question 20

obstructive

Answer 20

a block of blood flow in the heart or vessels -> insufficient blood supply to the body’s tissue

Question 21

syncope

Answer 21

loss of consciousness

Question 22

sphincters

Answer 22

circular muscles regulate the flow of fluid in the body

Question 23

septic shock

Answer 23

caused by severe infection, usually a bacterial infection

Question 24

pulmonary embolism

Answer 24

a blood clot that breaks off from a large vein and travels to the blood vessels of the lung

Question 25

psychogenic

Answer 25

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