You are being railroaded into taking an unsafe assignment. DO NOT DO IT.
Tell the DON no or you quit. Prepare the two week notice and have it with you, tell her and repeat it in the notice that you will not work on that unit while working out the notice. It may not go over very well, but they are giving you no choice.
Good luck. This is a case of any warm body will do, they are not caring if the patients get any care.
