Final answer:
The responsibility that is not typical for a medical assistant tasked with closing the office is scheduling appointments.
Step-by-step explanation:
The correct answer is C) Scheduling appointments. While a medical assistant tasked with closing the office would typically focus on tasks such as securing patient records, turning off lights and locking doors, and setting alarms, scheduling appointments is usually not part of their closing responsibilities. Scheduling appointments is a more common responsibility during regular office hours, when medical assistants help coordinate patient visits and manage the calendar. Closing the office, on the other hand, involves tasks related to security and facility management.
