Which field focuses on applying information technology to manage and communicate medical information?

• A. Informatics
• B. Radiology
• C. Pathology
• D. Oncology

Answer: (A)

This question tests how information technology is used in healthcare to manage and communicate medical information. Informatics is the field that combines IT with medicine to organize, store, retrieve, analyze, and securely share patient data, supporting electronic health records, interoperability, decision support, and health information exchange. That makes it the best fit for describing the application of information technology to handle and convey medical information. The other options are clinical specialties focused on specific areas of care—radiology on imaging, pathology on lab diagnosis, and oncology on cancer treatment—not on the IT-driven management and communication of medical data.
