I believe that a refresher course would be a very good place to start. It would also serve as a means of networking. Med Surg would be a good place to develop the skills that you feel that you are lacking based on lack of consistent experience. Everyone has to start somewhere, right?
I was in the military myself for seven years although not as a nurse. I became a nurse only after the end of my military contract. I understand how difficult it is to pack up everything every couple of years to have to start over elsewhere. I would imagine that moving so frequently as a civilian is even harder. Always having to have job gaps, orienting, starting over at multiple jobs, etc. Being a part of the military, it is a much smoother transition job wise. I sympathize.
In orientations, I have encountered women such as yourself who have been away from nursing who are there for refreshers. I believe that these recruiters would have to understand that life simply happens. As long as you show effort and motivation, I do not see why you could not attain a position as a RN. After having went through all of that schooling to attain your license, you need to be a practicing RN. That is my humble opinion anyway. Good luck to you!!
