I am not a nurse, but I own an assisted living. I can tell you that family members like this are common. We handle situations like these by faxing the MAR to the primary MD and ask him to sign off on it. You have done 2 things with this. You have brought it to the primary MD's attention to be addressed and you have passed the liability on to the right person--the doctor. He is and should be responsible for deciding what medications his patient is taking. Since assisted living is regulated by the state, regulations vary from state to state. I, however do not allow any medications in my building that we don't keep, hand out and document--even tylenol.
