Stroke part 4

Question 1

4 types of Shocked!
_________
Obstructive
cardiogenic
________

Answer 1

hypovolemic

distributive

Question 2

Loss of plasma or whole blood

Answer 2

hypovolemic

Question 3

Blockage in vessel

Answer 3

Obstructive

Question 4

cardiac origin/deficiency

Answer 4

cardiogenic shock

Question 5

loss of vaso-tone;too much vasodilation

(different from the rest)

Answer 5

distributive

Question 6

Hypovolemic,obstructive, cardiogenic shock are all due to what?

Answer 6

decrease in cardiac output

Question 7

Distributive shock is due to total peripheral resistance

Question 8

Blood volume contributes to stroke volume through what?

Answer 8

venous return

Question 9

If you decrease blood volume you decrease venous return, decrease preload, decrease stroke volume, decrease cardiac output and then you decrease blood pressure

Question 10

Causes of hypovolemic shock

Loss of whole blood (trauma)

Loss of ______ (Burns)

Loss of extracellular fluid (dehydration, vomiting, diarrhea)

Answer 10

plasma

Question 11

Obstructive shock
mechanical obstruction of blood flow
Ultimately one of these two decrease ________ which is due to obstructive prevents the heart from filling or increase in __________(obstruction prevents the heart from pumping)

Answer 11

decrease preload

increase in afterload

Question 12

Obstructive shock
Obstruction of blood flow out of LV–>dissecting aortic aneurysms
RV–>pulmonary embolism

increase in ______ which decreases stroke volume, decreases cardiac output, and decrease blood pressure

Answer 12

afterload

Question 13

obstructive shock

fluid accumulates in the pericardial sac=cardiac tamponande (a form of obstruction preventing the heart from filling) decrease preload, decrease stroke volume, decrease cardiac output, decrease blood pressure

Question 14

Causes of obstructive shock
which conditions increase afterload and decrease stroke volume –>

Answer 14

dissecting aortic aneurysms

pulmonary embolism
