Approach 3rd Edition (2025)

,Chapter 1: An Introduction to Health Informatics
1. A nurse practitioner is joining an interprofessional team implementing a new EHR
system. Which action best exemplifies the core function of health informatics in
this context?
A. Installing software for team members
B. Collecting patients’ opinions about the EHR
C. Facilitating the flow of clinical information between team members
D. Training only nurses on how to document effectively
ANS: C
Rationale: Health informatics focuses on improving communication and access to
clinical information across disciplines. Option C reflects informatics’ primary
purpose. The other choices are narrow or non-representative.
2. A hospital system is analyzing health outcomes across different departments. What
key informatics concept supports this process?
A. Health literacy
B. Data silos
C. Interoperability
D. Manual charting
ANS: C
Rationale: Interoperability allows different health systems to communicate,
facilitating data sharing across departments. Manual charting and data silos hinder
this process.
3. During a pandemic, a nurse leader uses real-time dashboards to allocate ICU beds.
What role is health informatics playing in this situation?
A. Basic documentation
B. Workflow distraction
C. Decision support
D. Legal compliance
ANS: C
Rationale: Informatics tools like dashboards support timely, informed decisions—
critical in emergencies. This demonstrates real-world clinical decision support
functionality.
4. A nurse is using a clinical decision support system (CDSS) that recommends
medication dosages. What is the nurse’s primary responsibility?
, A. Rely entirely on the system
B. Override recommendations without review
C. Use clinical judgment to interpret the recommendations
D. Ignore CDSS in critical care
ANS: C
Rationale: CDSS supports—not replaces—clinical judgment. Nurses are
responsible for integrating data with their expertise.
5. A nurse is documenting patient care in an EHR but cannot retrieve historical data
from a different hospital. What informatics challenge is being experienced?
A. System downtime
B. Interoperability failure
C. Encryption error
D. Coding mismatch
ANS: B
Rationale: This scenario illustrates a lack of interoperability—systems that cannot
exchange or interpret shared data effectively.
6. An APRN develops an app to track patients’ blood glucose levels. Which domain of
health informatics does this represent?
A. Teletriage
B. Mobile health (mHealth)
C. Robotics
D. Data warehousing
ANS: B
Rationale: mHealth includes apps and portable tech that monitor patient health
outside clinical settings. This is a direct application of informatics in patient
engagement.
7. A patient uses an online portal to view lab results and message providers. What
informatics tool is being used?
A. Decision tree
B. Clinical registry
C. Personal health record (PHR)
D. Order entry system
ANS: C
Rationale: A PHR empowers patients to manage their health by accessing and
interacting with personal health data.
, 8. Which of the following best illustrates informatics’ role in promoting patient safety?
A. Paper charting to reduce screen time
B. Text reminders to attend appointments
C. Automated alerts for medication interactions
D. Nurse documentation of vitals
ANS: C
Rationale: Informatics systems enhance safety by identifying risks like medication
interactions. Automated alerts are a key informatics safety feature.
9. A nurse leader is tasked with choosing an EHR for a multi-site organization. What’s
a primary informatics consideration?
A. Brand popularity
B. User interface design for non-clinicians only
C. System’s ability to support clinical workflows and data exchange
D. Free version availability
ANS: C
Rationale: A system must integrate with clinical workflows and enable data
exchange—core to effective informatics implementation.
10. A nurse documents a patient’s allergy incorrectly, leading to an adverse drug event.
What health informatics principle was breached?
A. Data governance
B. Firewall management
C. Device calibration
D. Ethics in research
ANS: A
Rationale: Data governance includes data accuracy, integrity, and stewardship.
Inaccurate documentation violates informatics standards and jeopardizes patient
safety.
11. A nurse informaticist is leading training on an upgraded clinical documentation
system. Which action best supports knowledge translation?
A. Providing printed manuals only
B. Demonstrating real-case scenarios in system training
C. Limiting access to superusers
D. Encouraging only passive observation
ANS: B
Rationale: Applying clinical scenarios helps bridge the gap between knowledge
and practice—central to knowledge translation in informatics education.
