I work as a nurse and I was told I’d made a medication error. Basically the pharmacist had noticed that a drug packet with a similar name to the drug prescribed was found in the patients locker with one tablet missing. She said I must have given the patient this tablet by mistake. I know I didn’t as I used the patients own dosset box. I’m not sure how this drug packet landed in the patients own locker but I know I didn’t make a med error. How do I clear my name?
