1. A nurse notices a patient’s blood pressure readings have been
consistently elevated over the past week. This pattern represents
which component of the DIKW model?
A. Data
B. Information
C. Knowledge
D. Wisdom
✅ Rationale: The nurse has identified a meaningful pattern from multiple
data points, which transforms information into knowledge.
2. Which organization officially recognized nursing informatics as a
nursing specialty in 1992?
A. HIMSS
B. American Nurses Association (ANA)
C. TIGER Initiative
D. QSEN
✅ Rationale: The ANA officially recognized nursing informatics as a
specialty in 1992.
3. Which of the following is the correct hierarchy of the DIKW model?
A. Knowledge → Wisdom → Data → Information
B. Data → Information → Knowledge → Wisdom
C. Information → Data → Wisdom → Knowledge
D. Wisdom → Knowledge → Information → Data
✅ Rationale: The DIKW model progresses from raw data to meaningful
information, then to knowledge, and finally to wisdom.
,4. A nurse uses clinical judgment to decide whether to notify a
provider about a critical lab value. This represents which level of the
DIKW model?
A. Data
B. Information
C. Knowledge
D. Wisdom
✅ Rationale: Wisdom involves applying knowledge to make appropriate
clinical decisions.
5. Which initiative focuses on preparing nurses to practice in a digitally
enabled healthcare environment?
A. HITECH Act
B. TIGER Initiative
C. MACRA
D. HIPAA
✅ Rationale: The TIGER Initiative aims to integrate technology into
nursing education and practice.
6. Which of the following is a core competency for nursing
informatics?
A. Performing surgery
B. Managing and analyzing clinical data
C. Prescribing medication
D. Diagnosing diseases
✅ Rationale: Nursing informatics focuses on data management,
information systems, and technology to support patient care.
7. What is the primary focus of nursing informatics?
A. Replacing nurses with technology
B. Improving patient outcomes through data and technology
C. Reducing nursing documentation
D. Eliminating paper charts
✅ Rationale: Nursing informatics integrates nursing science with
technology to enhance patient care and outcomes.
,8. A nurse enters a patient’s temperature of 101.5°F into the EHR. This
is an example of:
A. Data
B. Information
C. Knowledge
D. Wisdom
✅ Rationale: Raw, unprocessed facts like a single temperature reading are
data.
9. A nurse compares a patient’s current temperature to their baseline
and notes a trend. This is an example of:
A. Data
B. Information
C. Knowledge
D. Wisdom
✅ Rationale: Data that has been interpreted and given context becomes
information.
10. Which role is responsible for bridging the gap between clinical
staff and IT departments?
A. Physician assistant
B. Informatics nurse
C. Medical coder
D. Hospital administrator
✅ Rationale: Informatics nurses serve as liaisons between clinical
workflows and technology solutions.
11. Which of the following is a benefit of nursing informatics?
A. Increased medication errors
B. Improved communication among healthcare teams
C. Longer patient hospital stays
D. Reduced access to patient data
✅ Rationale: Informatics enhances data sharing and collaboration across
disciplines.
, 12. A nurse uses an EHR to document care. This technology primarily
supports:
A. Patient transportation
B. Clinical documentation and data retrieval
C. Surgical procedures
D. Facility maintenance
✅ Rationale: EHRs are designed for documenting and accessing patient
health information.
13. Which statement best describes "information" in the DIKW model?
A. Raw numbers and facts
B. Data that has been interpreted and given meaning
C. Application of knowledge to a situation
D. The highest level of clinical reasoning
✅ Rationale: Information is data that has been processed, organized, or
structured to make it meaningful.
14. The ANA’s Scope and Standards of Practice for Nursing Informatics
includes standards for:
A. Only IT professionals
B. Professional performance and practice
C. Only hospital administrators
D. Only nursing assistants
✅ Rationale: The standards apply to informatics nurses’ clinical and
professional responsibilities.
15. A nurse uses a clinical dashboard to view unit-wide infection rates.
This is an example of using:
A. Only data
B. Information and knowledge
C. Only wisdom
D. Only raw facts
✅ Rationale: Dashboards aggregate data into meaningful information for
decision-making.
