I work at at Methadone Center. Mon 6AM the 2 RNs (myself included) attempted multiple times to open our safe and retrieve the necessary medication to begin our daily doing of outpatient clients (they call them clients rather than patients here). After multiple attempts by both nurses, we were unable to unlock safe. We contacted our supervisor at home via cell and were given instructions to contact a locksmith and have them come ASAP to open the safe. The locksmith arrived at approx 06:40, by 0930 they had opened the safe and we began our routine of daily doing. Clients that had arrived while safe was NOT open were informed of situation, given the clinics number, instructed to call back to see when/if safe was open and they could return to dose later in the day. At the end of our work day, 2 clients had called to let us know that they would not be able to make it back to clinic- two never informed us of their decision to not return that day. This information was communicated to DON by our supervisor. She (the DON) then insisted that we were to fill out medication error forms for these clients. We told our supervisor that we would be very glad to fill out whatever Occurrence/Incident form they desired to document what had happened that day, but would not fill out med errors as we did not believe there was a med error! Our supervisor informed me that the DON had told him it would be insubordination if we do not fill out a med error for each client that did not dose on Moneday., and I quote, "Any beginning nurse know that this is a med error"- I have been a nurse for >29yrs, my co-worker have been a RN for approx the same # of years. I guess my question is....IS THIS A MED ERROR? WOULD YOU SIGN ONE? WHAT SHOULD WE DO? She expects this from us on Moneday. Help!!!
