Examination Overview. This 50-question glossary terminology examination mirrors the structure, cognitive
demand, and applied reasoning required by WGU D220 Informatics for Nursing Practice. Items are organized across
the six core terminology domains of the new program curriculum: core informatics terminology, health information
systems, standardized terminologies and classification systems, legal/ethical/regulatory terminology, informatics
competencies and roles, and emerging technologies. Each item provides a single verified correct answer, three
field-tested distractors representing the most common D220 glossary pitfalls (DIKW level confusion, EHR vs. EMR
confusion, privacy vs. security confusion, and standardized terminology identification errors), and a detailed
rationale grounded in foundational informatics definitions and concept distinctions.
How to Use This Exam. Complete each section in sequence. After selecting your answer, review the rationale to
reinforce the precise terminology distinction that determined the correct response. The rationales emphasize ANA
definitions, the DIKW hierarchy (data, information, knowledge, wisdom), standardized terminology scope
(SNOMED-CT, ICD, LOINC, NANDA, NIC, NOC), HIPAA/HITECH/MACRA compliance principles, TIGER and
QSEN informatics competencies, and emerging technologies that are reshaping nursing practice.

Q1: Which term is correctly defined as the science of information processing and management,
encompassing the structure, algorithms, and behavior of information systems?
A. Nursing informatics
B. Informatics [CORRECT]
C. Health informatics
D. Biomedical informatics
Correct Answer: B
Rationale: Informatics is broadly defined as the science of information processing and management, encompassing
the structure, algorithms, and behavior of information systems. Option A (nursing informatics) is the specialty that
integrates nursing science with informatics; option C (health informatics) is the application of informatics in
healthcare broadly; option D (biomedical informatics) is the intersection of biology, medicine, and informatics. The
general term 'informatics' is the parent discipline, with the others being subdomains.
Q2: Per the American Nurses Association (ANA), how is nursing informatics correctly defined?
A. The use of computers to document nursing care 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 [CORRECT]
C. The study of how nurses use technology at the bedside to monitor vital signs
D. The application of computer science to nursing administration and management
Correct Answer: B
Rationale: The ANA defines nursing informatics as the specialty that integrates nursing science with multiple
information and analytical sciences (including computer science and information science) to identify, define, manage,
and communicate data, information, knowledge, and wisdom in nursing practice. Option A is overly narrow and
equates informatics with documentation; option C focuses on bedside monitoring only; option D restricts informatics
to administration. The ANA definition emphasizes the integration of disciplines and the DIKW framework central to
nursing informatics practice.
Q3: A nurse records a patient's temperature of 101.2°F. In the DIKW framework, this numeric value
is best classified as:
A. Knowledge
B. Wisdom
C. Data [CORRECT]
D. Information
Correct Answer: C
Rationale: In the DIKW framework, data are raw, unprocessed facts and figures without context or interpretation; a
numeric temperature reading of 101.2°F by itself is data. Option A (knowledge) is synthesized information applied to
a situation, such as recognizing a fever pattern; option B (wisdom) is the appropriate application of knowledge, such
as deciding to administer an antipyretic based on the fever; option D (information) is data given meaning through
context, such as 'the patient's temperature is 101.2°F, which is above normal.' Distinguishing DIKW levels is a
common D220 exam challenge.

Q4: A nurse reviews a patient's trended vital signs over 24 hours and recognizes a pattern of
gradually increasing temperature and heart rate, suggesting possible infection. Which level of the
DIKW framework does this pattern recognition represent?
A. Data
B. Information
C. Knowledge [CORRECT]
D. Wisdom
Correct Answer: C
Rationale: Knowledge is information that has been synthesized and applied to a situation; recognizing a pattern of
rising temperature and heart rate as suggestive of infection represents knowledge because the nurse has combined
trended information with clinical understanding to derive meaning. Option A (data) is the raw numbers; option B
(information) is the data organized with context (the trended values); option D (wisdom) is the appropriate
application of that knowledge — for example, deciding to culture blood or notify the provider. D220 students
frequently confuse knowledge and wisdom because both involve clinical reasoning.
Q5: After recognizing that a patient's rising vital signs suggest infection, the nurse uses clinical
judgment to decide whether to administer antipyretics, draw cultures before antibiotics, or
escalate to the provider immediately. This decision-making reflects which DIKW level?
A. Data
B. Information
C. Knowledge
D. Wisdom [CORRECT]
Correct Answer: D
Rationale: Wisdom is the appropriate application of knowledge to a specific context — deciding what action to take
based on synthesized information, clinical knowledge, ethical principles, and the individual patient's situation. Option
A (data) is raw facts; option B (information) is processed data; option C (knowledge) is the recognition of the
infection pattern, but wisdom is the decision about what to do. Wisdom incorporates values, ethics, and judgment,
distinguishing it from knowledge, which is the synthesis itself.
Q6: A hospital is implementing a new barcode medication administration system that requires
nurses to scan patient wristbands and medication labels before administration. Which informatics
concept is most directly addressed by ensuring the system is intuitive and minimizes extra clicks?
A. Interoperability
B. Usability [CORRECT]
C. Data integrity
D. Standardized terminology
Correct Answer: B
Rationale: Usability refers to the ease of use and user-friendliness of a system, including how intuitively users can
complete tasks with minimal errors and frustration; an intuitive barcode scanning workflow with minimal clicks
directly addresses usability. Option A (interoperability) is the ability of different systems to exchange and use
information; option C (data integrity) is the accuracy and consistency of data; option D (standardized terminology) is
a common language for documentation. Poor usability leads to workaround behaviors and errors, making it a critical
informatics concept.
