shock

Question 1

shock

Answer 1

abnormality of the circulatory system resulting in inadequate tissue perfusion and oxygenation
inadequate tissue perfusion and oxygenation
anaerobic metabolism
accumulation of metabolic waste products
cellular failure

Question 2

hypovolaemic shock

Answer 2

loss of blood volume
decreased blood volume
decreased venous return
decreased stroke volume

Question 3

cardiogenic shock

Answer 3

decreased cardiac contractility
decreased stroke volume
not volume replacement

Question 4

tension pneumothorax

obstructive shock

Answer 4

increased intrathoracic pressure
decreased venous return
decreased stroke volume

Question 5

neurogenic shock

Answer 5

loss of sympathetic tone too blood vessels and heart
venous and arterial vasodilation
decreased venous return and SVR
decreased heart rate

Question 6

vasoactive shock

Answer 6

release of vasoactive mediators
venous and arterial vasodilation
decreased cardiac output and SVR

Question 7

treatment of shock

Answer 7

ABCE
high flow oxygen 
volume replacement 
inotropes for cardiogenic shock 
immediate chest drain for tension pneumothorax 
adrenaline for anaphylactic shock 
vasopressors for septic shock 
treat cause
