Get out and apply as a graduate. I'm assuming you've taken boards. If you haven't taken your boards, you have to do that first.
Depends on the state. In some you can apply as a graduate nurse until you take boards. If you pass boards you have your license. If you do not pass boards you can no longer work as a graduate nurse.
Kind of tough in Iowa. Maybe working as a tech in an area of interest while your finishing up.
