Final answer:
In this scenario, a physician can be double-booked once every two hours. This means that during a two-hour block of time, only one patient can have the same appointment time as another.
Step-by-step explanation:
In this scenario, a physician can be double-booked once every two hours. This means that during a two-hour block of time, only one patient can have the same appointment time as another. So the correct answer is A. 1.
If it is office policy that a physician can be double-booked once every two hours, this means that two patients could have the same appointment time. Since a regular appointment slot would be for one patient, double booking would increase this to having two patients scheduled at the same time. Therefore, the correct answer is B. 2.
