My father (70)was admitted for kidney stones.

Last night at about 7pm my father was admitted to a local hospital for kidney stones. He was diagnosed with dementia last year, and still knows who my immediate family members are. My mom was unable to stay with him as she still works and is unable to take days after a long break.

Basically what I’m trying to ask is: Should I be there with him, even though there’s nothing I can do?
