I didn't realize that I had asked such an "extremely difficult legal question".
It's not an "extremely difficult legal question".
This is not the appropriate forum for such a question though.
And there are details that you CAN NOT provide (for a number of reasons but just a couple: You are not a party to the issue at hand and what information you do have will have been obtained by your position--and the information you have is PHI! There's this little thing called HIPAA...)
Example:
*How old is this person? Can you answer that without knowledge you gained from the person's chart
*What are his diagnoses/diagnosis? (and for goodness sake don't actually post them)
*Is he a danger to himself or to others if he is not on a locked unit? (sounds like if he gets confused, refuses to seek help to ambulate, etc. he is most definitely at risk for harming himself)
*Does he have someone as a POA? (again, can't answer that one without info you got from his chart), Or a family member assisting with decisions? or perhaps a court order of some sort?
*Do you see this man 24/7? Or just on the shift that you work? How often do you see him? Could his behavior/condition vary greatly when you aren't there?
If you want to be a patient advocate, then I suggest you get yourself into some sort of case management line of work. But, you still don't need to broadcast the situation on a very public message board.
Learn to respect your patient's privacy. I'm beginning to wonder exactly what sort of nursing education you have!
