How do I get my supervisor to quit doing jobs for everybody else?

My supervisor is someone who always has to be doing something. She has a hard time feeling comfortable not doing something if she s working on the clock. Our facility is coming up on our state survey and time in the near future, and my supervisor is good friends with the company administrator. She wants to make sure that we do our part to make sure all of our stuff is in order for our department, but because my supervisor has a hard time not doing something she decides that any time she sees something that someone else is supposed to do she goes out of her way to try to get it done, which includes pulling myself and the other employee in our department away from whatever we are doing at the time. She says the reason is because every time we try to report to the person who s supposed to be responsible for making sure the other departments do their jobs, nothing ever gets done about it. She makes all of our lives so much harder, and I keep trying to convince her to let it go because it isn t our responsibility. Does anyone have any recommendations for what I can do to convince her that she is putting way too much on our plate?
