Anyone had this situation? Geez Louise

Seriously, I need some advice.

I went to my admit today, a male, pelvic fx post car accident. 80 yr old pt. Daughter was present, she is an RN, there to stay until tomorrow. Patient has dementia. Pt's wife and primary caregiver has started showing signs, no not signs, I would say is full blown into Alzheimer's. Daughter, an RN is very tearful about situation. At start of visit daughter gets a call from her mom who is at pharmacy and has lost her keys and now has no idea where she is. Daughter goes to get her. When mom comes in she starts to cry, hit herself and say "Why is this happening to me" Mom calms down. I take daughter (RN) aside and say "Mom CANNOT drive anymore" she starts to cry and says "That the only thing she has left, I can't take that away from her" I basically say in a very caring manner that that is too bad but she's going to kill someone.

I call the doc and get to speak to the MA. Now, no offense, but I want to speak to a nurse or a doctor to tell them how serious this is. I got a gum-snapping "Uh huh, what was his INR?" NOT AS RELEVANT at this point.

I finally left and watched as the daughter took her mom to the store to pick up her car and drive it home. Do I call APS?
