, 1. Multiple-choice
A community hospital is onboarding an interface engine to transform HL7
v2 ADT messages from its registration system into FHIR Patient resources
for the regional HIE.
Which layer of interoperability (per ONC’s four-tier model) is being
addressed?
A. Foundational
B. Structural
C. Semantic
D. Organizational
ANS B – Structural
Rationale: Message syntax and transport (HL7 v2 → FHIR) are structural
concerns; semantic meaning and governance are handled elsewhere.

2. Multiple-choice
During integration testing, you discover that the lab’s LIS sends
potassium values as “K+” but the receiving EHR expects the LOINC code
2823-3. The safest, lowest-burden fix is to:
A. Edit every LIS result manually before messaging
B. Map “K+” to 2823-3 in the interface engine’s vocabulary table
C. Ask the EHR vendor to accept local codes
D. Disable potassium transmission until the LIS is upgraded
ANS B
Rationale: A one-time semantic mapping inside the middleware
normalizes data without manual re-work or unsafe downtime.

, A home-care RPM platform pushes weight data via a RESTful API
protected by SMART on FHIR OAuth 2.0. What is the chief nurse-
informatics advantage of using SMART on FHIR instead of a proprietary
token scheme?
A. Eliminates need for encryption
B. Enables patient-matching without an MPI
C. Provides vendor-agnostic single sign-on and granular scope control
D. Doubles data-transfer speed
ANS C
Rationale: SMART standardizes auth/authorization, letting any compliant
app obtain limited-scope EHR data with one set of credentials.

4. Multiple-choice
Your system implements IHE XDS.b for cross-enterprise imaging. Which
message pattern is central to this profile?
A. Publish/subscribe events
B. Document registry and repository with SOAP-based queries
C. UDP multicast streams
D. HL7 v3 RIM-based clinical statements
ANS B
Rationale: XDS.b uses a registry–repository architecture exposed through
SOAP web-service calls.

5. Multiple-choice
When a patient portal pulls allergies from an EHR using the USCDI data
set, the exchange exemplifies which federal rule?
A. TEFCA “QHIN-to-QHIN” exchange
B. 21st Century Cures Act Information-Blocking Provision
C. CMS Promoting Interoperability (Meaningful Use) Hard Stop
