1. Which of the following best describes the ethical obligation of 'veracity' in health informatics practice? → Being truthful and transparent in communications
2. What distinguishes an advanced health informatician practitioner's approach to risk management & mitigation from that of a novice? → Establishing cross-functional teams with clearly defined roles
3. Which messaging standard is most widely used for exchanging clinical data between health IT systems in the US? → HL7 v2
4. Which FHIR resource would a health informatician use to represent a patient's active medication list for exchange between systems? → MedicationStatement or MedicationRequest
5. During a tabletop exercise, a health system simulates a ransomware attack on its clinical systems. What is the primary goal of this exercise? → To evaluate staff and leadership response without disrupting live systems
6. A health informatician overhears a conversation revealing a colleague is fabricating usability study results. The MOST ethical response is to: → Report the misconduct to a supervisor or ethics committee
7. During a quality assurance & compliance audit, which documentation is most critical to have readily available? → Conducting root cause analysis to identify underlying systemic issues
8. Which scenario demonstrates an ethical application of secondary use of health data? → Using de-identified data to study population health trends with IRB approval
9. What is the role of interoperability in clinical workflow? → Facilitates seamless communication between systems
10. A health informatician is asked to alter clinical data to support a favorable outcome in a malpractice case. This action would violate which principle? → Data integrity
11. What is the primary function of an Electronic Health Record (EHR) system? → Storing and managing patient health records
12. Which federal regulation establishes the Security Rule requiring covered entities to implement administrative, physical, and technical safeguards for ePHI? → HIPAA
13. In health informatics, 'organizational readiness' for a new system refers to: → An organization's capacity and willingness to successfully implement and sustain a change
14. What is the primary risk of using overly technical jargon when communicating health IT project updates to clinical staff? → It creates comprehension barriers, leading to disengagement and potential resistance
15. What is the primary benefit of telehealth technology? → Improves healthcare accessibility
16. Which scenario represents an appropriate use of de-identified data under the HIPAA Safe Harbor method? → Removing all 18 specified identifiers before sharing data for research
17. A health informatician discovers a colleague is accessing patient records without clinical need. What is the MOST appropriate first action? → Report it to the privacy officer or compliance department
18. Which federal regulation most directly influences how health informaticians communicate about patient data with external stakeholders? → HIPAA
19. Which ethical principle requires health informaticians to act in the best interest of patients rather than their own interests? → Beneficence
20. According to professional ethics standards, continuing education for health informaticians is important primarily because: → Competence must be maintained as health IT evolves to protect patient safety
21. In the context of health informatician, which principle most directly governs ethics, regulations, & compliance in health informatics practices? → Applying evidence-based methodologies with peer-reviewed support
22. Which statistical process control tool is MOST useful for visualizing whether a healthcare quality metric remains within expected variation limits over time? → Control Chart (Shewhart Chart)
23. Which metric is MOST useful for evaluating the success of a health IT system implementation from a leadership perspective? → User adoption rate and measurable improvement in clinical or operational outcomes
24. A clinical informatics team discovers that nurses are not using a newly implemented medication reconciliation module. What should be the FIRST step? → Conduct interviews to understand workflow barriers
25. Which document formally defines the roles, responsibilities, and authority levels of stakeholders in a health IT governance structure? → RACI matrix
26. What is the purpose of a 'heat map' in risk management reporting? → To visualize risk ratings by plotting likelihood against impact for quick prioritization
27. In health informatics, a 'feedback loop' in stakeholder communication refers to: → A mechanism for stakeholders to respond to communications and influence project decisions
28. A health informatician professional discovers a discrepancy during communication & stakeholder engagement review. What is the most appropriate immediate action? → Engaging stakeholders collaboratively to align goals and expectations
29. HEDIS measures are used primarily to evaluate performance in which setting? → Managed care health plans
30. What is the main advantage of using quantitative risk analysis over qualitative analysis? → It produces numeric financial estimates enabling cost-benefit comparisons for controls
