  1. An affiliated clinic and hospital assign different medical record numbers to the same patient. Which IHE profile cross-references these identifiers across domains?

    Answer: PIX

    The IHE Patient Identifier Cross-Referencing (PIX) profile links a patient's identifiers across multiple identifier domains.

  2. In an IHE XDS.b affinity domain, what is the role of the document registry?

    Answer: It indexes document metadata so documents can be located

    The XDS registry holds searchable metadata and pointers, while repositories store the documents themselves.

  3. A web-based viewer must retrieve radiology images from a PACS over RESTful services. Which standard family is the most appropriate?

    Answer: DICOMweb

    DICOMweb defines RESTful services, such as WADO-RS, for retrieving DICOM imaging objects over HTTP.

  4. A primary care practice sends a referral summary directly to a specialist's address through a HISP. Which mechanism is the Direct Project based on?

    Answer: SMTP email secured with S/MIME and X.509 certificates

    Direct secures push messaging between known participants using SMTP, S/MIME encryption, and X.509 certificates.

  5. An enterprise master patient index links records from two different people because their demographics are nearly identical. What is this error, and why does it matter?

    Answer: A false positive that can combine clinical data unsafely

    A false positive match wrongly links different patients and can expose clinicians to another person's allergies, medications, or results.

  6. A prescriber's EHR transmits a new prescription electronically to a community pharmacy. Which standard is primarily used for this transaction in the US?

    Answer: NCPDP SCRIPT

    NCPDP SCRIPT is the primary US standard for electronic prescribing messages between prescribers and pharmacies.

  7. A security architect must ensure systems in an HIE authenticate each other and record access to patient data. Which IHE profile addresses both requirements?

    Answer: ATNA

    The IHE Audit Trail and Node Authentication (ATNA) profile defines secure node authentication and audit logging.
