CPMS Healthcare Data Management & Interoperability 5 — Questions and Answers
Question 1: Which data quality dimension refers to the completeness of required data elements in a healthcare record?
- Completeness (Correct answer)
- Accuracy
- Timeliness
- Consistency
Correct answer: Completeness
Completeness measures whether all required data elements are present and populated within a healthcare record.
Question 2: A care coordination platform needs to alert a provider when a patient is admitted to any hospital in a network. Which FHIR mechanism is most appropriate?
- FHIR Subscriptions (Correct answer)
- FHIR Batch Bundle
- FHIR $everything operation
- FHIR Patch
Correct answer: FHIR Subscriptions
FHIR Subscriptions allow a server to push notifications to registered clients when specified resources are created or changed.
Question 3: In HL7 V2 messaging, which segment contains patient identification information such as name, date of birth, and medical record number?
- PID (Correct answer)
- MSH
- PV1
- OBX
Correct answer: PID
The PID (Patient Identification) segment in HL7 V2 carries demographic data including patient name, date of birth, gender, and identifiers.
Question 4: A hospital is migrating its EHR and needs to convert legacy SNOMED CT codes to ICD-10-CM for a new billing system. What type of artifact facilitates this?
- A cross-map or concept map (Correct answer)
- A FHIR CapabilityStatement
- A data dictionary
- An HL7 conformance profile
Correct answer: A cross-map or concept map
Cross-maps (or concept maps) provide systematic mappings between different code systems, enabling translation of coded data during migrations or integrations.
Question 5: Which ONC certification criterion requires EHRs to support patient access to their data via a standardized API?
- §170.315(g)(10) – Standardized API for patient and population services (Correct answer)
- §170.315(b)(1) – Transitions of Care
- §170.315(a)(14) – Implantable device list
- §170.315(e)(1) – View, download, and transmit to 3rd party
Correct answer: §170.315(g)(10) – Standardized API for patient and population services
ONC criterion §170.315(g)(10) mandates FHIR R4-based APIs enabling patients and third-party apps to access EHR data without special effort.
Question 6: In a FHIR implementation, what is the purpose of a CapabilityStatement resource?
- To declare the FHIR features, resources, and operations supported by a server (Correct answer)
- To define the value sets required for a particular use case
- To map patient identifiers across multiple healthcare systems
- To specify the encryption algorithms used for data at rest
Correct answer: To declare the FHIR features, resources, and operations supported by a server
A CapabilityStatement documents what a FHIR server supports, including resource types, interactions, search parameters, and operations, discoverable at the /metadata endpoint.
Question 7: When de-identifying protected health information under HIPAA, which method requires removal of 18 specific identifiers and expert confirmation of very low re-identification risk?
- Expert Determination method (Correct answer)
- Safe Harbor method
- Limited Data Set method
- Statistical Sampling method
Correct answer: Expert Determination method
The Expert Determination method allows an expert to certify that the risk of re-identification is very small, even if some identifiers beyond the Safe Harbor list remain.
