Do people sometimes get a Guardianship when they really don’t need it?

Many times a doctor or nursing home personnel will say you need to get a Guardianship over your Mom.

What they are really saying is that “ medically speaking” your Mom is medically incompetent and unable to take care of herself or make rational and meaningful decisions regarding her financial affairs and healthcare decisions. But from a legal standpoint Mom may or may not really need a Guardianship.
