Help! I don't know what this is about?

Hi all,

I've been lurking for years since I was student. Now, almost 5 years later as an RN, I have an interesting issue.

I have been working as a med/surg RN for little more than 4 years FT nights, then verbally accepted an outpatient position a week ago at a non-affiliated system. Paperwork wasn't done & submitted yet. A day after the verbal acceptance, I had a phone interview for another job within the health system just to keep my options open. The phone interview led to an appointment for an in person interview -- scheduled for Friday. I'm honestly feeling "meh" about this in-system job, compared to the outpatient one. But again,options open.

Then I receive a call from my manager yesterday. I assumed it was because the in-system interviewer had contacted her because I would be a transfer. I'd been needing to call her to resign from my position anyway; I developed an interest outside of med/surg, which was a great place to start, by the way. I called her back the next day after, as I was busy fulfilling duties related to the outpatient position.

It turns out, she had no idea about my job hunting (which is good, I suppose, since I never advertised that I had accepted any position, just that I was looking at jobs in general). She wants to meet me with HR for something entirely different, and she won't give me details! I have no idea what THIS new thing is about. She mentioned med administration issues.... she also took me off the schedule until this meeting.

I wracked my brain, can't come up with any med errors. Can't come up with anything for that matter. I know a few months ago I was supposed to grind up a tablet to give as a slurry but it wasn't a narcotic. I was already "chatted with" about that. I don't document less than any other nurse on this floor,; but I'm not perfect and I may have missed something that I didn't know I missed.

I searched on here and most everything wrong with nurses and med admin have to do with narcotic diversion, which I am not nor will I ever do. I am willing to submit any part of my body at at any time for drug testing. I even quickly bought malpractice insurance after reading posts on here, because as a nurse, I'm always "just in case".

In any case, I resigned on the phone during this call, as I was planning on doing regardless, when the outpatient position's paperwork was done. I also emailed my resignation letter. I'm thinking of cancelling the interview on Friday; the outpatient position seems solid now that I did all the paperwork and physical.

So what should I do? The job search had nothing to do with this new "meet with HR" thing, it was happening weeks ago; a paper trail would show when I applied, had interviews, etc. Should I call my malpractice insurance? Hire a lawyer? Personal people in my life tell me "Don't worry about it, if you did nothing wrong, why are you worried?" But I am. I can't sleep (well). But I know I will not sign anything unless I know what I'm signing for.

So, what the **** is going on here? Any constructive opinions, recommendations, advice welcomed. Thanks :/
