Which statement best describes FHIR?

• A. A narcotics prescription schedule
• B. A web-based standard enabling easier integration and APIs
• C. A patient scheduling algorithm
• D. A clinical decision support rule set

Answer: (B)

FHIR is a web-based standard designed to make healthcare data flow smoothly between systems through open APIs. It uses familiar web technologies like RESTful interfaces and JSON or XML, and it breaks information into small, reusable pieces called resources (such as Patient, Observation, Medication) that can be combined to support real-world workflows. This approach makes integration easier because developers can connect different systems using standard formats and operations, implement parts of the standard quickly, and swap components without a full rewrite. The statement about FHIR being a web-based standard that enables easier integration and APIs captures this essence.

Other options miss the point: a narcotics prescription schedule isn’t about how data is exchanged; a patient scheduling algorithm focuses on timing and logistics rather than data interoperability; a clinical decision support rule set is about decision logic, while FHIR provides the data transport framework that can support CDS by supplying the necessary data.
