CoolKids brings up some very valuable points.
It seems like leaving it off your resume could come back to bite you. Most hospital job applications require that you list all prior degrees; you'd either have to list it, or risk having your offer rescinded (or even being fired) if your manager discovered that you'd omitted that information.
You say that you never actually worked as a nurse. If you leave med school off of your resume, you'd appear to have a weird, long employment gap from nursing school
to the present, which I'm sure would come up during your interview (assuming you could even get an interview due to said weird, long employment gap).
Furthermore, you'd be in a strange position because you'd technically be a 'new grad' nurse, having never worked as a nurse before. New grad positions are pretty competitive, and managers expect a return on their investment; some hospitals even have 'pay back' contracts if you leave a new grad position in less than 2 years (anywhere from $2,000 to $5,000).
I think that it would be a mistake to leave it off of your resume, but realize that you may actually be at a distinct disadvantage applying to nursing positions given your history. As CoolKids said, I'd be prepared to address these concerns very tactfully in your applications and interviews.
Best of luck.
