Something I have learned from just recently taking a re-cert course is that you can't take too much time contemplating. There will most likely be 2 right answers. I immediately narrowed it down to 2, and simulated both answers. I tried to keep it down to about a minute a piece. Of course...
I personally don't think it is too ridiculous. It comes down to quality of life. If I had an active DNR and my life was extended which meant that I had the honor of spending another year at a SNF, I would be pretty angry.
