,1. In a FHIR R5 implementation, which resource best represents a clinical decision
support rule?
A. PlanDefinition
B. Questionnaire
C. CarePlan
D. Library
Answer: A. PlanDefinition

PlanDefinition is the FHIR resource used to define a clinical decision support rule,
including triggers, conditions, and actions. Questionnaire is for data collection,
CarePlan is for patient care coordination, and Library stores logic but is not the rule
itself.

2. Under the 2024 HIPAA Reproductive Health Privacy Rule, which is required for
disclosures of reproductive health info?
A. Attestation that disclosure is not for prohibited purposes
B. Patient's written consent for any disclosure
C. Approval by the hospital ethics committee
D. Mandatory reporting to law enforcement
Answer: A. Attestation that disclosure is not for prohibited purposes

The 2024 rule requires an attestation from the requester that the disclosure is not for a
prohibited purpose (e.g., criminal, civil, or administrative investigations). Patient
consent is not always required, ethics committee approval is not mandated, and law
enforcement reporting is not mandatory for reproductive health.

3. Which LOINC component best maps to a serum creatinine measurement?
A. Creatinine [Mass/volume] in Serum or Plasma
B. Creatinine clearance
C. Creatinine kinase
D. Creatinine renal clearance
Answer: A. Creatinine [Mass/volume] in Serum or Plasma

LOINC distinguishes creatinine mass/volume in serum/plasma from clearance and
kinase. The correct LOINC for serum creatinine is 'Creatinine [Mass/volume] in Serum
or Plasma'. The others represent different analytes or clearance measurements.

,4. In information governance, which principle ensures data is accurate and
complete?
A. Data integrity
B. Data availability
C. Data confidentiality
D. Data stewardship
Answer: A. Data integrity

Data integrity ensures accuracy and completeness. Availability ensures access when
needed, confidentiality ensures privacy, and stewardship is the oversight of data assets.

5. Which TEFCA role is responsible for enabling nationwide exchange?
A. QHIN
B. HIE
C. HISP
D. RHIO
Answer: A. QHIN

Qualified Health Information Networks (QHINs) are the backbone of TEFCA,
connecting networks for nationwide exchange. HIEs, HISPs, and RHIOs are regional or
directed exchange entities, not the TEFCA nationwide backbone.

6. Which analytics method predicts 30-day readmission risk using historical EHR
data?
A. Logistic regression
B. Descriptive statistics
C. Data visualization
D. Cluster analysis
Answer: A. Logistic regression

Logistic regression is a predictive modeling technique suitable for binary outcomes like
readmission. Descriptive statistics and visualization summarize data, and cluster
analysis is unsupervised grouping.

, 7. What is the primary purpose of the 21st Century Cures Act information blocking
rule?
A. To promote patient access to electronic health information
B. To mandate EHR certification
C. To establish HIPAA privacy standards
D. To require clinical decision support
Answer: A. To promote patient access to electronic health information

The information blocking rule aims to prevent practices that interfere with access,
exchange, or use of electronic health information, promoting patient access. EHR
certification is separate (ONC), HIPAA is privacy, and CDS is not the focus.

8. Which CDS intervention is most likely to cause alert fatigue?
A. Frequent non-specific drug interaction alerts
B. Annual wellness reminders
C. Order sets for common conditions
D. Evidence-based guidelines
Answer: A. Frequent non-specific drug interaction alerts

Frequent, non-specific alerts, such as many drug interaction warnings, are a major
cause of alert fatigue. Reminders, order sets, and guidelines are generally less frequent
and more targeted.

9. Which SNOMED CT hierarchy directly supports problem list coding?
A. Clinical finding
B. Procedure
C. Substance
D. Organism
Answer: A. Clinical finding

The 'Clinical finding' hierarchy in SNOMED CT includes diagnoses and symptoms
used for problem lists. Procedure, Substance, and Organism are separate hierarchies.
