Millie, an established patient, calls at 11:15 am on Friday morning to say that she has fallen off a step and may have fractured her ankle. She states that she cannot put any weight on her ankle and it is swollen. She states she is not in any pain unless she tries to walk. Her neighbor is available to drive her to the office. You check today's schedule and see that there are no open appointments. Actually, appears the schedule has double bookings. What is the best way to respond to the patient?
