1. Late in pregnancy, a patient often develops supine hypotension because of a. partial occlusion of the vena cava and aorta. b. decreased peripheral collateral circulation. c. increased blood flow to the placenta. - Answer-A because of partial occlusion of the vena cava and aorta from the weight of the uterus.
