I work in an OB dept and ours is a closed unit and we don't have floaters or registry from outside. This is due to the amount of orientation involved. You have to really know what to watch for as far as dfundal firmness etc.. The risk for hemmorhage is to great to allow floating. Just keep watching for the openings. Our hospital has a internship program and sometimes we hire new grads that went through an internship. Hope this helps!
