Hi.. I currently work at a hospital in NJ and I am a nursing student. I am going to give you some great advice! Keep your secretarial job for now. Volunteer on your first aid squad where they will train you at no cost to become an emt. After you have pt experience reapply to all the tech jobs. Trust me you'll get a job. That's how I did it :).
I just had a great lecture on technology as it relates to the nursing field. Here is a great supplemental article that was used; http://www.chcf.org/~/media/Files/PDF/E/PDF%20EquippedForEfficiency.pdf
