Informatics Nurse Test Health Information Exchange 2 — Questions and Answers
Question 1: Which HL7 standard is most commonly used for real-time HIE messaging in clinical workflows?
- HL7 v2
- CDA R2
- FHIR R4 (Correct answer)
- EDI X12
Correct answer: FHIR R4
HL7 FHIR R4 is now the predominant modern standard for interoperable, RESTful health information exchange in clinical workflows.
Question 2: An informatics nurse is helping implement a medication reconciliation workflow using HIE. The PRIMARY benefit is:
- Reducing documentation time for billing
- Providing a complete medication history from all care settings to reduce discrepancies (Correct answer)
- Eliminating the need for pharmacist review
- Automating insurance prior authorizations
Correct answer: Providing a complete medication history from all care settings to reduce discrepancies
HIE-enabled medication reconciliation gives clinicians access to medication records from all providers, reducing the risk of errors from incomplete histories.
Question 3: Which document standard is used to transmit a structured clinical summary (e.g., discharge summary) via HIE?
- HL7 v2 ADT message
- C-CDA (Consolidated Clinical Document Architecture) (Correct answer)
- DICOM
- X12 837
Correct answer: C-CDA (Consolidated Clinical Document Architecture)
C-CDA is the standard for structured clinical documents exchanged via HIE, including Continuity of Care Documents and discharge summaries.
Question 4: A patient who has opted out of HIE participation has their data:
- Deleted from all participating organizations
- Excluded from being shared through the HIE network per their preference (Correct answer)
- Automatically shared only with government agencies
- Visible to emergency departments regardless of opt-out
Correct answer: Excluded from being shared through the HIE network per their preference
HIE opt-out means the patient's data will not be accessible to other participating organizations through the exchange network.
Question 5: In the context of HIE, a Record Locator Service (RLS) is used to:
- Retrieve full patient records from remote systems
- Identify which organizations hold records for a specific patient (Correct answer)
- Encrypt data during transmission
- Assign unique patient identifiers
Correct answer: Identify which organizations hold records for a specific patient
An RLS is a directory service that identifies which participating organizations have records for a given patient without holding the data itself.
