Well.. the frst thing I will say is that once again, my argument is supported! Hospitals that put new grads in critical care areas simply by virtue of the fact that they have a license and a pulse... may not be providing the best solution to staffing problems...
Having said that, I will say that I feel for you as a colleague.
As an earlier poster said, med errors are rampant. And unfortunately, if the order does not cover the full amount of the drug you signed out, and there is no record of waste, you are technically guilty of diverting controlled substances.
Equally unfortunate is the fact that you are assumed to be intentionally deceptive until proven otherwise.
The fact that you volunteered for a drug screen is a plus, but it does not prove a lack of criminal intent.
If the institution has reported you to the BON, get a lawyer. If they have not reported you and they are going to handle it internally as an education issue, get a lawyer anyway. Prefereably on who is an RN,JD.
Finally, no matter what, DO NOT LEAVE your position voluntarily. If you are reassigned, accept the reassignment continue to practice, and accept remediation as it is offered to you.
I am sure that right now, you think that this is the worst thing that can possibly happen to you...But you will see, if you are truly innocent (and it's my hunch that you are).. this too shall pass.
