being that I am from Canada it might help your search of info if you look under RPN as that is what our "version" of the LPN is titled
(registered practical nurse)
as for work in the hospital, it can happen immediately after nursing school and even before you write your nursing exam for your license. You have to obtain a temporary license to do so though
it helps to research all aspects of nursing and figure out what your goal is and where your interest lies.
then again that can change on a moments notice, afterall youre talking to a nurse who was supposed to be a journalist
good luck and keep us posted
