(15 cards)
Most common type of shock in surgical or trauma patient
hemorrhagic/hypovolemic
Result of acute blood loss EXCEPT
a. reflexive decreased baroreceptor stimulation
b. sympathetic stimulation
c. increased output from atrial stretch receptors
d. release of epinephrine and norepinephrine
C
T/F
