I would try and do some certifications. Certifications are a way to show you go above and beyond the basic training and are staying current. You can also earn CEUs for some.
You can do Stoke Certification through the National Institute of Health online. Just go to their website. Professional Education Center
I think it was only $10 when I took it.
ACLS is another good one although it does cost more.
You might check some of the hospital websites and see if there are any education courses. You could also call the nursing educator/dept and see if they would let you take a course for a fee. Usually it is the bigger hospitals that have them.
Some hospitals offer them for employees free but will charge for the general public (nurses that aren't employees). A friend of mine did an EKG course that way. She also did a pacemaker course.
Another tactic is try to volunteer. Okay I know its time consuming but it can help you get your foot into the door. Make friends with the nurse managers and swallow your pride and tell everyone yes I am already and RN and I am looking for a job and really want to work here! lol
Volunteering can be 4 hrs a week in the ER or where ever... pretty minimal. You could still do this in a hopital even if you were working at a nursing home or home care etc and wanted to just get your foot in the door at a acute care hospital.
Once you have volunteered for awhile, go introduce yourself to HR in people wearing your volunteer uniform. Ask them if they have any entry level RN positons available. Tell them you are already an RN and have a BSN, already passed your boards, etc etc. You love the place where you are volunteering already know the policies and want to work there. Keep checking in with them - in person.
