A 74-year-old man is brought by his daughter to the emergency room. When asked his name, he is unable to remember it and appears to be disheveled, restless, and confused. His daughter says that she has been caring for him at home for the last year, but he "ran away" after they had an argument about his deteriorating personal hygiene. She found him several hours later sitting in the street. She confides to the nurse that she feels horrible about yelling at her father. Which of the following is the BEST response by the nurse?
1. "We all do things that we are sorry for later."
2. "Don't feel guilty because he is confused."
3. "Your father's illness must be difficult for both of you."
4. "The social worker will be able to help you with this problem."
