Final answer:
The scheduling method where patients are seen on a first-come, first-served basis when they sign in is called open hours scheduling.
Correct option is B
Step-by-step explanation:
A scheduling method in which patients sign in and are seen on a first-come, first-served basis is known as open hours scheduling. This method allows for some flexibility as patients arrive at their convenience during the set open hours of the clinic or office. As a contrast, wave scheduling involves patients being scheduled at the same time and seen in sequence, cluster scheduling groups patients with similar issues or procedures, and open access scheduling, or same-day scheduling, allows patients to make appointments on the day they wish to be seen.
It differs from wave, cluster, and open access scheduling methods which have more structured appointment systems.
