Question 2

Shock stages

Answer 2

Compensated
Decompensatory
Irreversable

Question 3

Fick Principle

Answer 3

1. Adequate concentration of inspired O2
2. on-loading of O2 to red blood cells
3. Delivery of red blood cells to tissue cells
4. Off-loading of O2 from red blood cells to tissue cells

Question 4

Adequate concentration of inspired O2 requires

3

Answer 4

1. Adequate ventilation
2. high concentration of inspired O2
3. Unobstructed air passage

Question 5

on-loading of O2 to red blood cells requires

2

Answer 5

1. minimal obstruction across alveolar-capillary membrane
2. appropriate binding of O2 to hemoglobin

Question 6

Delivery of red blood cells to tissue cells requires

5

Answer 6

1. Normal hemoglobin levels
2. Circulation of oxygenated cells to tissue
3. adequate cardiac function
4. adequate colume of blood flow
5. Proper routing of blood through vasculature

Question 7

Off-loading of O2 from red blood cells to tissue cells requires

3

Answer 7

1. Close proximity of tissue cells to capillaries
2. Ideal Ph (7.35 - 7.45)
3. Ideal Temperature

Question 8

Types of shock

5

Answer 8

1. obstructive shock
2. Cardiogenic shock
3. Distributive shock
4. Hypovolemic shock
5. Respiratory/Metabolic shock

Question 9

Hypovolemic

Define

Answer 9

Shock from low blood volume or other body fluids

Question 10

Distributive shock

Define

Answer 10

Cant perfuse enough blood due to excessive vasodilation and increase in capillary permeability

Question 11

Cardiogenic shock

Define

Answer 11

Ineffective pump function of the heart. Hypoperfusion results from the inability of the heart to contract effectively

Question 12

Obstructive shock

Define

Answer 12

Everything is working effectively but theres an obstruction that wont allow blood to move forward

Question 13

Respiratory shock

Define

Answer 13

Dysfunction in the ability of oxygen to diffuse into the blood, be carried by hemoglobin, off-load at the cell, or be used effectively by the cell for metabolism
Ex. Cyanide

Question 14

Hypovolemic shock

Causes

(2)

Answer 14

1. Hemorrhagic
2. Nonhemorrhagic = Burns

Question 15

Cardiogenic shock

Causes

(6)

Answer 15

1. MI
2. CHF
3. Beta blocker/calcium channel blockers
4. Abnormal rhythm
5. Depressed pump function
6. overdose

Question 16

Obstructive shock

Causes (3)

is it reversible?

Answer 16

1. Tension pneumothorax
2. Pulmonary embolism
3. Pericardial tamponade

It is reversable

Question 17

Distributive shock

Causes (3)

Answer 17

1. Neurogenic
   Ex. Spinal cord injury
2. Septic
3. Anaphylactic

Question 18

Metabolic/Respiratory shock

Causes (3)

How long does this take to develop

Answer 18

Distubances in…
1. Oxygen diffusion
2. Oxygen transported to cells
3. Cells ability to take and use the oxygen
basiclaly any disturbances in the Fick principle

Takes a long time. Days or weeks

Question 19

Starlings law

Define

Answer 19

Cardiac output increases or decreases in response to changes in HR or stroke volume

Question 20

Answer 20

• Airway
• Breathing
• Circulation
• Narcan
• ALS

Question 21

S/S (3)

Treatment (1)

Answer 21

• N/V
• Burn pt

Treatment: IV fluid
