I agree with some others that you may be giving the wrong kind of information. I am an HR Director (and an RN) so I screen lots of applicants for various jobs. I have heard people say they had been terminated from a position for performance by saying, "I was not growing in the position and the termination was an eye-opener for me. It confirmed what I knew to be true - that I needed to be in another field." This would be a great segue for explaining what led you to embrace nursing. Another option may be to not even list it. If you were attending school at the time and this was only a 2 month stint, why mention it to perspective employers?
