Something similar happened on Nurse Jackie on the last (?) season.
And, as far as I am aware, insulin drips are a double RN check where you can't bypass the sign off in the flow sheets like you can with pressors. Granted, I guess this all depends on facility policy. In any case, it's a med error and likely to be reported which would result in either suspension or termination. Hopefully the hospital is unionized and not a right to fire facility.
