Oh my God! How could a nurse do this? I am horrified. I am an R.N. I can't see any reason to do this at all.
How could doctors do harm to their patients? Not every one is as good as you are. Remember there was a nurse up this way who went from hospital to hospital in the North and killed his patients? They didn't figure out that it always happened on his watch for quite a while. I think he killed eleven people before they got to him. Horrible, isn't it?
