In a patient who is hemorrhaging,which of the following is an adaptive response that helps to mantain mean arterial pressure ?
a.-increased end systolic volume
b.-increased venosu compliance
c.-inhibition of secretion of ADH {vasopressin}
d.-A fluid shift from interstitial to vascular compartements
e.-release of atrial natriuretic peptide

D
a.-increased end systolic volume --> decrease Stroke volume and therefore decrease BP
b.-increased venosu compliance--> decrease preload and therefore decrease BP
c.-inhibition of secretion of ADH {vasopressin}: ADH increases in hemorrhage
d.-A fluid shift from interstitial to vascular compartements: yes
e.-release of atrial natriuretic peptide: ANP decreases in hemorrhage

D is the strange one?!! This really happens after hemorrhage??
Isn't A in fact increased end DIASTOLIC volume? cedrick??

yes D...fluid does shift from interstitial compartment ( due to lowered capilliary hydrostatic pressure)..but it takes many hours to occur
