Re: Who has responsibility
1st off the keys for the med cart are your responsibility once you have given report, counted, and signed off. If someone else gets those keys, passes meds, etc. then it is your fault for not keeping better track of your keys. However, I would NEVER give meds to someone if those meds have been signed off already. When something is already signed off then DO NOT give again and reinitial it. Don't assume and if in doubt call the person that did initial it in the 1st place.
I do see your point that the nurse should NOT have touched your cart once she had passed it on. I would report her, write her up and let it go from there. However, at this point you need to admit your guilt as well if a resident was double dosed. Double doseing someone can be fatal depending on what meds were given.
