What is telemedicine, and what are common limitations in practice?

• A. In-person video calls only; limitations include lack of internet.
• B. Telemedicine is only for follow-up appointments; limitations include lack of real-time communication.
• C. Telemedicine requires patient consent; limitations include privacy concerns.
• D. Remote clinical care via telecommunications; limitations include technology access, privacy concerns, and lack of physical exams.

Answer: (D)

Telemedicine is remote clinical care delivered through telecommunications technology, allowing clinicians to assess, diagnose, and manage patients without an in-person visit. This can include real-time video visits, phone calls, messaging, or remote monitoring. That broad definition makes the statement the best choice because it captures the actual practice of delivering care at a distance.

Common limitations in practice include: uneven access to technology and reliable internet or devices, which can prevent some patients from using telemedicine; privacy and data-security concerns, since health information is transmitted and stored digitally; and the inability to perform a hands-on physical examination, which can limit assessment and may necessitate in-person follow-up or alternative examination methods.
