Can't help much except to say I read recently that multidose vials should be stored in nurses station and have med drawn up in nurses station then taken to room. The thinking is that one would be less likely to introduce a used needed back into a multidose vial. (as you know there have been many cases of Hepatitis C transmitted this way)
It seem like when I was in med school, we were taught to have the multidose vial right next to the patient so you could draw up the med right before the patient and be less likely to make a wrong med / wrong patient error.
