What does the base set of FHIR resources provide?

• A. A fundamental collection of resources that cover common use cases
• B. A vendor-specific extension library
• C. A security policy document
• D. A data warehouse schema

Answer: (A)

The base set of FHIR resources provides a standard collection of resource types that cover common use cases in healthcare data exchange. These core resources, such as Patient, Encounter, Observation, Condition, MedicationRequest, and Practitioner, form the shared foundation that enables systems to understand and exchange essential clinical and administrative data consistently across vendors. While extensions and profiles can customize or add domain-specific data, the base set itself is the interoperable building block that underpins widespread data sharing. It’s not a vendor-specific extension library, a security policy document, or a data warehouse schema.
