D) LOINC
Answer: B
Rationale: HL7 Fast Healthcare Interoperability Resources (FHIR) enables data
exchange between EHR systems using modern web-based APIs, promoting
interoperability .
, 11. What is the first step in the system development life cycle (SDLC) during EHR
implementation?
A) System design
B) Needs assessment
C) Implementation
D) Evaluation
Answer: B
Rationale: The SDLC begins with a needs assessment to identify user requirements
