Section 1: Foundations of Nursing Informatics (15 Questions)
Q1: A nurse informaticist is explaining the difference between data, information,
knowledge, and wisdom to a group of nursing students. Which example best represents
knowledge in the context of nursing informatics?
A. A patient's blood pressure reading of 142/88 mmHg
B. A trend showing the patient's blood pressure has increased 20% over three days
C. Understanding that this blood pressure trend indicates poorly controlled hypertension
requiring medication adjustment
D. The decision to increase the patient's antihypertensive dosage based on clinical
guidelines and patient-specific factors
Correct Answer: C
Rationale: In the DIKW (Data-Information-Knowledge-Wisdom) hierarchy, knowledge
represents the application of information to understand patterns, meanings, and
relationships. Option C demonstrates knowledge by interpreting the blood pressure
trend (information) to understand the clinical significance (poorly controlled
hypertension requiring intervention).
Why incorrect options are wrong:
● A: This is raw data—a discrete, objective fact without context
● B: This represents information—data processed into meaningful patterns and
trends
● D: This represents wisdom—the appropriate application of knowledge to make
sound clinical judgments considering multiple factors
,Q2: Which nursing informatics theory specifically addresses the cognitive processing of
information by nurses during clinical decision-making, emphasizing how nurses attend
to, interpret, and respond to data in the clinical environment?
A. Roger's Diffusion of Innovations Theory
B. Benner's Novice to Expert Theory
C. Cognitive Informatics Theory
D. Lewin's Change Theory
Correct Answer: C
Rationale: Cognitive Informatics Theory, developed by researchers including Wang and
others, specifically examines how nurses and other healthcare providers process
information cognitively. It explores attention, perception, memory, problem-solving, and
decision-making in the context of information technology and clinical practice. This
theory is fundamental to understanding how EHRs and clinical decision support
systems should be designed to match human cognitive processing capabilities.
Why incorrect options are wrong:
● A: Roger's theory addresses how new technologies and innovations spread
through populations, not individual cognitive processing
● B: Benner's theory describes skill acquisition and clinical judgment development
across experience levels, not information processing mechanisms
● D: Lewin's theory addresses organizational change management
(unfreeze-change-refreeze), not cognitive informatics
Q3: A hospital is implementing a new barcode medication administration (BCMA)
system. The nurse informaticist is analyzing how nurses interact with the technology
during medication passes. Which concept from the Technology Acceptance Model
(TAM) best explains whether nurses will actually use the new system?
,A. The system's compatibility with existing nursing workflows
B. Perceived usefulness and perceived ease of use
C. The hospital's organizational culture and leadership support
D. The cost-benefit ratio of the technology implementation
Correct Answer: B
Rationale: Davis's Technology Acceptance Model (TAM) identifies two primary
determinants of technology adoption: perceived usefulness (the degree to which a
person believes using the system enhances job performance) and perceived ease of
use (the degree to which a person believes using the system will be free of effort).
These perceptions directly influence attitudes toward using the system, which then
predict actual system use. This model is widely applied in nursing informatics to predict
and improve EHR adoption.
Why incorrect options are wrong:
● A: Compatibility is a construct from Roger's Diffusion of Innovations, not TAM
● C: Organizational culture is addressed in other change theories but not in the
core TAM framework
● D: Cost-benefit analysis is an economic evaluation method, not part of TAM's
psychological constructs
Q4: According to the QSEN (Quality and Safety Education for Nurses) Informatics
Competencies, which skill is considered essential for the graduate-level nurse?
A. Navigating the EHR to locate patient demographic information
B. Using information and technology to communicate, manage knowledge, mitigate
error, and support decision-making
C. Troubleshooting hardware malfunctions in the nursing unit
D. Programming clinical decision support rules in the EHR
Correct Answer: B
, Rationale: QSEN identifies informatics as one of six core competencies for nursing,
defining it as the use of information and technology to communicate, manage
knowledge, mitigate error, and support decision-making at the point of care. This
competency applies to all nurses, with increasing sophistication at graduate and
doctoral levels. Graduate-level nurses are expected to integrate informatics to improve
patient outcomes, not just perform basic tasks.
Why incorrect options are wrong:
● A: Basic navigation is an entry-level expectation, not graduate-level competency
● C: Hardware troubleshooting is typically IT support staff responsibility, not core
nursing informatics competency
● D: Programming decision support rules is typically the role of informatics
specialists or IT analysts, not general graduate nursing practice
Q5: A nurse is caring for a patient with complex comorbidities. The EHR aggregates
data from multiple sources (lab results, medication history, vital signs, nursing
assessments) into a single dashboard view. Which informatics concept does this
represent?
A. Data warehousing
B. Information visualization and data integration
C. Clinical decision support
D. Natural language processing
Correct Answer: B
Rationale: Information visualization involves presenting data in graphical or dashboard
formats to facilitate rapid comprehension, while data integration combines information
from disparate sources into unified views. This scenario describes both
concepts—aggregating multiple data types (integration) into a dashboard (visualization)
