He goes on to tell you that he can't get his wife to schedule a doctor's appointment for him and when she remembers to call, the office is always closed. Which of the following is the BEST way to proceed?
A) Ask him why he decided to call 911 today.
B) Try to call his doctor to schedule an appointment.
C) Ask him for a list of his medications.
D) Begin your assessment of his vital signs.
