NU 225 Nursing Informatics
Complete Final Exam (Qns & Ans)
2025
1. Scenario: A hospital plans to upgrade its Electronic Health
Record (EHR) system. The nurse informaticist is tasked with
participating in the system’s development. Which phase of the
system development life cycle (SDLC) is most critical for
identifying user requirements?
Options:
A) Design
B) Implementation
C) Analysis and Planning
D) Evaluation
ANS: C) Analysis and Planning

, Rationale: The analysis and planning phase is where end-user
requirements are gathered and documented. This is critical to
ensure the new system meets the clinical and operational needs of
its users.
2. Scenario: After a new EHR is implemented, clinicians report
difficulty navigating its interface, leading to documentation
delays. Which strategy is most effective in addressing these
usability issues?
Options:
A) Mandate its use without modifications
B) Conduct usability testing and collect user feedback for
iterative improvements
C) Immediately revert to the previous system
D) Limit access to only senior clinical staff
ANS: B) Conduct usability testing and collect user feedback
for iterative improvements
Rationale: Engaging end users through usability testing and
iterative feedback is essential to refine system features, improve
efficiency, and enhance user satisfaction.
3. Scenario: A nurse informaticist is tasked with ensuring that
the hospital’s EHR can exchange data with other systems
nationwide. Which concept best facilitates that process?
©2025
, Options:
A) Interoperability
B) Data encryption
C) System isolation
D) Proprietary software
ANS: A) Interoperability
Rationale: Interoperability refers to the ability of different
information systems to communicate, exchange, and use data
cohesively, ensuring continuity of care across healthcare settings.
4. Scenario: A clinical decision support system (CDSS)
integrated into an EHR alerts clinicians to potential drug–drug
interactions. What is the primary benefit of a CDSS in this
context?
Options:
A) It replaces the need for clinical judgment.
B) It reduces medication errors and enhances patient safety.
C) It increases the workload on nurses.
D) It only provides alerts without actionable recommendations.

, ANS: B) It reduces medication errors and enhances patient
safety.
Rationale: A CDSS supports clinicians by providing real-
time alerts and recommendations—helping to prevent errors and
improve the overall quality of patient care.
5. Scenario: When assessing data security in the hospital’s
informatics system, which federal regulation should the nurse be
most aware of to ensure patient privacy?
Options:
A) GDPR
B) HIPAA
C) HITECH
D) OSHA
ANS: B) HIPAA
Rationale: The Health Insurance Portability and
Accountability Act (HIPAA) sets national standards to safeguard
patient health information and ensures privacy and security in
healthcare settings, which is a cornerstone of nursing informatics.
6. Scenario: A nurse informaticist is tasked with implementing
a mobile health (mHealth) application in a community clinic.
