An older adult male client, who is a retired chef, is hospitalized with a diabetic ulcer on his foot. His daughter tells the nurse that her father has become increasingly obsessed with the way his food is prepared in the hospital. The nurse's response should be based on which information?

If the client was compulsive about food when he was younger, the aging process can magnify this.

The client probably has an organic brain disease and will likely have Alzheimer's disease within a few years.

The daughter is under stress and should be encouraged to think about happier times.

The family needs a social worker to talk to them about how to handle their father when he becomes annoying.
