Shock part 5

Question 1

Causes of obstructive shock
Decrease preload and decrease stroke volume—>

Answer 1

cardiac tamponade and tension pneumothorax

Question 2

Cardiogenic shock
Heart fails to pump enough blood for needs
Decrease blood pressure and decrease cardiac output

decrease in cardiac output due to decrease in heart rate or decrease in stroke volume or
traumatic increase in heart rate we talked about tachycardia or bradycardia can cause decline in cardiac output

Question 3

Both arrhythmias and contractility issues can cause cardiogenic shock

Question 4

causes of cardiogenic shock
damage from myocardial infarction (MI)
acute heart failure
valvular damage
ineffective pumping due to arrhythmias (either too fast or too slow)
ventricular aneurysm

Question 5

due too much vasodilation=__________shock

Answer 5

distributive shock

Question 6

if you increase radius too much your going to decrease total peripheral resistance and that will decrease blood pressure in distributive shock

Question 7

3 types of distributive shock
Neurogenic shock
anaphylactic shock
septic shock

Question 8

due to spinal cord injury–>hypotension+bradycardia

what type of shock is this?

Answer 8

neurogenic shock

Question 9

Presence of inflammatory mediatators
septic shock
anaphylactic shock

Question 10

___________
vasodilatory shock due to systemic infection due to inflammatory response–>leaky and dilated vessels

Answer 10

septic shock

Question 11

____________
vasodilatory shock
severe allergic reaction

Answer 11

anaphylactic shock

Question 12

Hypervolemic shock,obstructive shock, and cardiogenic shock all involve what

compensation: increase TPR which causes extremities:cold, pale, mottling

Answer 12

cardiac output

Question 13

Distributive shock involves low ______

compensation increase cardiac output
extremities:warm, pink/red, no mottling

Answer 13

TPR
