Patient in hypovolemic shock - the clues are low BP and COOL skin. Hypovolemic shock is caused by fluid loss.
The patient has decreased preload b/c of fluid loss, i.e. there is decreased blood volume returning to heart --> thus decreased preload.
@endochondral w/ hypovolemic shock you would see increased systemic arterial resistance as arteries will constrict to try and bring BP back up.
