,1. Which system lifecycle phase involves usability testing and a scenario requiring WGU
C790 nursing informatics competency. The nurse informaticist must apply data
management, systems analysis, and ethical principles. What is the most appropriate
evidence-based action per WGU OA standards?
A. Apply DIKW model, ensure data quality, and optimize EHR workflow per usability principles
B. Misinterpret data analytics
C. Disable CDS alerts without evaluation
D. Bypass privacy controls and share PHI via unsecured channels
Answer: A
Rationale: Selected option aligns with telehealth, consumer health informatics, and emerging trends including
AI, big data analytics, and precision health per WGU C790. It integrates privacy, security, ethics, and
interprofessional collaboration while evaluating outcomes. Alternatives violate HIPAA, ignore data analytics,
or fail to address workflow. This high-yield content demonstrates informatics competency needed for WGU
C790 OA success and modern nursing practice. Domain: privacy.
2. During workflow analysis for CPOE implementation, the informaticist identifies
workarounds. The NGN-style action is a scenario requiring WGU C790 nursing informatics
competency. The nurse informaticist must apply data management, systems analysis, and
ethical principles. What is the most appropriate evidence-based action per WGU OA
standards?
A. Neglect data governance
B. Apply DIKW model, ensure data quality, and optimize EHR workflow per usability principles
C. Disable CDS alerts without evaluation
D. Bypass privacy controls and share PHI via unsecured channels
Answer: B
Rationale: Selected option aligns with telehealth, consumer health informatics, and emerging trends including

3. Which system lifecycle phase involves usability testing and a scenario requiring WGU
C790 nursing informatics competency. The nurse informaticist must apply data
management, systems analysis, and ethical principles. What is the most appropriate
evidence-based action per WGU OA standards?
A. Misinterpret data analytics
B. Evaluate CDS effectiveness, monitor analytics, and ensure privacy and security per HIPAA
C. Disable CDS alerts without evaluation
D. Skip usability testing
Answer: B
Rationale: Selected option aligns with telehealth, consumer health informatics, and emerging trends including
AI, big data analytics, and precision health per WGU C790. It integrates privacy, security, ethics, and
interprofessional collaboration while evaluating outcomes. Alternatives violate HIPAA, ignore data analytics,

, 4. During workflow analysis for CPOE implementation, the informaticist identifies
workarounds. The NGN-style action is a scenario requiring WGU C790 nursing informatics
competency. The nurse informaticist must apply data management, systems analysis, and
ethical principles. What is the most appropriate evidence-based action per WGU OA
standards?
A. Implement system without stakeholder input
B. Disable CDS alerts without evaluation
C. Evaluate CDS effectiveness, monitor analytics, and ensure privacy and security per HIPAA
D. Skip usability testing
Answer: C
Rationale: This answer reflects evidence-based nursing informatics including CDS, EHR optimization,
workflow design, and human factors. It considers usability, clinical judgment, and system evaluation per AMIA
and ANI guidelines. Distractors bypass privacy, ignore security, or fail to assess workflow impact. Mastery of
informatics systems, privacy HIPAA, and ethics ensures safe technology implementation and is frequently
tested on WGU C790 OA exam. Domain: privacy.
5. During workflow analysis for CPOE implementation, the informaticist identifies
workarounds. The NGN-style action is a scenario requiring WGU C790 nursing informatics
competency. The nurse informaticist must apply data management, systems analysis, and
ethical principles. What is the most appropriate evidence-based action per WGU OA
standards?
A. Neglect data governance
B. Apply DIKW model, ensure data quality, and optimize EHR workflow per usability principles
C. Disable CDS alerts without evaluation
D. Ignore data quality and proceed without validation
Answer: B
Rationale: Selected option aligns with telehealth, consumer health informatics, and emerging trends including
AI, big data analytics, and precision health per WGU C790. It integrates privacy, security, ethics, and
interprofessional collaboration while evaluating outcomes. Alternatives violate HIPAA, ignore data analytics,
or fail to address workflow. This high-yield content demonstrates informatics competency needed for WGU
C790 OA success and modern nursing practice. Domain: foundations.
6. During workflow analysis for CPOE implementation, the informaticist identifies
workarounds. The NGN-style action is a scenario requiring WGU C790 nursing informatics
competency. The nurse informaticist must apply data management, systems analysis, and
ethical principles. What is the most appropriate evidence-based action per WGU OA
standards?
A. Implement system without stakeholder input
B. Assess telehealth outcomes, ensure consumer engagement, and leverage future informatics
trends
C. Fail to assess system interoperability
D. Bypass privacy controls and share PHI via unsecured channels
Answer: B
Rationale: Selected option aligns with telehealth, consumer health informatics, and emerging trends including
AI, big data analytics, and precision health per WGU C790. It integrates privacy, security, ethics, and
interprofessional collaboration while evaluating outcomes. Alternatives violate HIPAA, ignore data analytics,
