Section 1: Foundations of Nursing Informatics (14 Questions)
Q1: A nurse informaticist is explaining the core concept of nursing informatics to a
group of nursing students. Which statement best defines the scope and purpose of
nursing informatics according to the American Nurses Association (ANA)?
A. The use of computer hardware and software to document patient care activities in
electronic health records
B. The specialty that integrates nursing science with multiple information and analytical
sciences to identify, define, manage, and communicate data, information, knowledge,
and wisdom in nursing practice
C. The technical support role responsible for troubleshooting computer problems and
maintaining hospital networks
D. The administrative function focused on budgeting for technology purchases and
managing IT staff
Correct Answer: B
Rationale: The ANA defines nursing informatics as "the specialty that integrates nursing
science with multiple information and analytical sciences to identify, define, manage,
and communicate data, information, knowledge, and wisdom in nursing practice" (ANA,
2015). This definition emphasizes the DIKW framework (Data, Information, Knowledge,
Wisdom)—the theoretical foundation of nursing informatics. Data are raw facts (e.g.,
vital signs); information is data with context (trending blood pressure); knowledge is
information synthesized with clinical expertise (recognizing hypertension pattern);
wisdom is applying knowledge ethically for patient benefit (intervening appropriately).
,Nursing informatics is not merely technical support (C) or administrative management
(D), nor is it limited to EHR documentation (A). It encompasses the full spectrum of
information management to support clinical decision-making, improve outcomes, and
advance nursing science.
Why other options are incorrect:
● A: This describes a limited technical application (EHR use) rather than the
comprehensive scope of nursing informatics as a specialty.
● C: This describes information technology (IT) support roles, not nursing
informatics which requires advanced nursing education and clinical expertise.
● D: This describes healthcare administration or IT management, not the clinical
specialty of nursing informatics.
Q2: A hospital is implementing a new clinical information system. The nurse
informaticist is applying the Technology Acceptance Model (TAM) to predict user
adoption. According to TAM, which two factors are the primary determinants of whether
nurses will accept and use the new technology?
A. System functionality and vendor reputation
B. Perceived usefulness and perceived ease of use
C. Cost of implementation and return on investment
D. Hardware specifications and network speed
Correct Answer: B
Rationale: The Technology Acceptance Model (TAM), developed by Fred Davis (1989), is
a widely used theoretical framework in nursing informatics to predict and explain user
acceptance of information technology. TAM posits that two key beliefs determine
technology acceptance: (1) Perceived usefulness (PU)—the degree to which a person
believes that using a particular system would enhance their job performance (e.g., "This
EHR will help me provide better patient care"); and (2) Perceived ease of use
(PEOU)—the degree to which a person believes that using a particular system would be
,free of effort (e.g., "This system is intuitive and easy to learn"). These beliefs influence
attitudes toward use, behavioral intention to use, and actual system use. TAM has been
extended (TAM2, TAM3, UTAUT) to include social influence, facilitating conditions, and
other variables, but PU and PEOU remain core constructs. Understanding TAM helps
nurse informaticists design implementation strategies that address user concerns and
optimize adoption.
Why other options are incorrect:
● A: While system functionality matters, vendor reputation is not a core TAM
construct; user perceptions of the system's utility and usability drive adoption,
not external vendor factors.
● C: Cost and ROI are organizational concerns, not individual user acceptance
factors in TAM; users rarely base adoption decisions on financial metrics.
● D: Technical specifications influence PEOU indirectly but are not the primary
determinants; users assess subjective ease of use, not objective hardware
specs.
Q3: A nurse is reviewing a patient's trending vital signs displayed as a graph in the EHR.
This transformation of raw numbers into a visual pattern represents which level of the
DIKW framework?
A. Data
B. Information
C. Knowledge
D. Wisdom
Correct Answer: B
Rationale: The DIKW framework (Data-Information-Knowledge-Wisdom) is a hierarchical
model fundamental to nursing informatics. Data are discrete, objective facts without
context (e.g., "BP 140/90," "HR 88"). Information is data that have been processed,
organized, structured, or presented in a given context to make them meaningful (e.g., a
graph showing BP trending upward over 3 days, or "BP elevated compared to patient's
, baseline"). Knowledge is information synthesized with experience, rules, and
relationships to inform decisions (e.g., "This BP pattern indicates possible postoperative
hypertension requiring intervention"). Wisdom is the appropriate use of knowledge to
manage and solve human problems, involving ethics and judgment (e.g., "I will notify the
provider and initiate antihypertensive protocol while considering this patient's
preferences and comorbidities"). The graph described represents information—data
(vital signs) organized into a meaningful visual pattern that reveals trends, but not yet
interpreted with clinical expertise or applied with judgment.
Why other options are incorrect:
● A: Data are raw, unprocessed facts; the graph represents processed,
contextualized data (information).
● C: Knowledge requires interpretation, pattern recognition with clinical expertise,
and understanding of relationships; merely viewing a trend graph does not
constitute knowledge.
● D: Wisdom involves ethical application of knowledge to complex situations; this
scenario describes an earlier stage in the hierarchy.
Q4: A nursing informatics specialist is designing a clinical decision support (CDS) tool
that alerts nurses when a patient's fall risk score exceeds a threshold. This intervention
represents which level of the DIKW framework?
A. Data collection
B. Information processing
C. Knowledge application
D. Wisdom integration
Correct Answer: C
Rationale: This scenario represents knowledge application in the DIKW framework. The
CDS tool integrates data (patient assessment responses), processes them into
information (calculated fall risk score), and applies knowledge (evidence-based rule: "If
fall risk score >X, then alert nurse to implement fall precautions"). Knowledge involves
