Final answer:
Practice Management Software is typically used by healthcare providers to schedule, reschedule, and cancel appointments, and it integrates with other systems like EHRs while ensuring patient privacy.
Step-by-step explanation:
The application in which you schedule, reschedule, and cancel the patient's appointment is typically known as Practice Management Software (C). This software often integrates with other systems such as Electronic Health Records (EHR) to provide a seamless experience for managing patient information, scheduling, billing, and more. While a Patient Portal may also offer these features to patients directly, the primary software used by healthcare providers for managing appointments is Practice Management Software. Ensuring the privacy of electronic health records is paramount, and both EHR systems and Practice Management Software are designed with security measures to protect patient information.
