Terminated, now what?

Hey This is my first post. I feel like I have to start from the beginning so you guys can understand completely.

I Graduated 2010 with my BSN in NYC. During this time it was super hard to find a job in nyc. I started looking in nj and pa focusing mainly on acute care. After a year I landed a PRN job giving Hepatitis B vaccines. Not much experience there :/. A year later I finally got a real job working in a long term facility, Elizabeth Seton. Of course it's not that acute care experience that I wanted, but I was desperate. As you all know the saying, if you don't use it, you will loose it. I felt everything I learned in nursing school was slowly slipping away even if I tried reading my med surg books.

I stayed there for a year but still applied to acute care positions. I finally was able to get a job working at a ortho floor in PA(They said it's like a Med-surg floor). They also had med-surg and trauma patients as well. You could imagine it was a bit overwhelming. It was basically like I was a New Grad that has been out of school for 3 years! I still tried my hardest and studied when I got home, trying to brush up on policies and procedures that were common on the floor.

Three months go by and my NM sits down with me and says she can't take me off orientation because I cannot consistently maintain a 5 patient load. I was able to at times but there were times that all hell breaks loose and everything happens all at the same time and it took me a little while to try to prioritize what to do first.

My NM extended orientation for 1 more month. I did get better but I still was unable to consistently care for the 5 patient load without becoming overwhelmed. We finally sat down and she explained that she had to terminate me.

Now I'm here, almost 3 months later with no job. I had gone on a few interviews but of course the first question is... why were you terminated. I told them the whole story but I'm finding that hospitals are resistant to let me try again, afraid it'll happen again.

I don't know what to do. I need experience to do anything else, but can't get it. How can I word my answer to why I was terminated. I know I cant leave it off my resume so now what? I am DESPERATE!!! What are my options? Any help will be appreciated. I know this was a very long message but I feel like perhaps this might have happened to some new grad and I do not see any post about it.
