,1. A 58-year-old patient with chronic heart failure is admitted. The
nursing informatics specialist configures the clinical decision support
(CDS) system to alert nurses for elevated potassium when
administering loop diuretics. Which interoperability standard ensures
the CDS alert accurately integrates lab results into the EHR?
a. ICD-10
b. SNOMED CT
c. HL7 FHIR
d. DICOM
ANS: c. HL7 FHIR
Rationale: FHIR defines modular “resources” and RESTful APIs for
exchanging clinical data like lab observations in real time, enabling
seamless CDS integration.
2. During an EHR upgrade, the informatics team maps local allergy
terms to a standardized vocabulary to improve data comparability
across systems. Which terminology should they select to represent
allergies at a granular clinical level?
a. LOINC
b. RxNorm
c. SNOMED CT
d. CPT
ANS: c. SNOMED CT
Rationale: SNOMED CT provides comprehensive, fine-grained
clinical terms for documenting allergies and adverse reactions,
supporting interoperable data exchange.
3. A nursing informatics team implements a telehealth platform. To
ensure seamless communication with the hospital’s scheduling
system, which integration approach is most appropriate?
a. Manual data entry
2
, b. Batch file transfer via FTP
c. Real-time API calls using HL7 FHIR
d. Periodic CSV imports
ANS: c. Real-time API calls using HL7 FHIR
Rationale: Real-time FHIR APIs reduce latency and errors by
enabling immediate updates between telehealth appointments and
the scheduling module.
4. In establishing a data governance framework for patient
information, which component is essential to define user access
rights and responsibilities?
a. Data dictionary
b. Metadata repository
c. Role-based access control (RBAC) policy
d. Data backup schedule
ANS: c. Role-based access control (RBAC) policy
Rationale: RBAC policies outline which roles can access or modify
specific data, enforcing least-privilege principles and regulatory
compliance.
5. A predictive analytics model is developed to identify patients at
high risk for inpatient falls. Which performance metric best evaluates
the model’s ability to correctly identify those high-risk patients?
a. Specificity
b. Sensitivity
c. Accuracy
d. Precision
ANS: b. Sensitivity
Rationale: Sensitivity (true positive rate) measures how well the
model detects actual high-risk patients, critical in fall prevention
interventions.
