Hemorrhage initiates a series of compensatory responses. Which of the following statement(s) is/are true concerning the physiologic responses to hemorrhagic shock?
A. An immediate response is an increased sympathetic discharge with resultant reflex tachycardia and vasoconstriction
B. Transcapillary refill is a response serving to restore circulating volume
C. Extracellular fluid becomes increasingly hyperosmolar
D. Adrenergically mediated vasoconstriction is well maintained at the arteriolar and precapillary sphincters
