WGU C790 Exam 2026 [Actual Test] Complete Questions
& 100% Correct Verified Solutions | Newest Version
1. A nurse enters a patient's blood pressure reading of "120/80" into the
electronic health record. At this moment, before any clinical context is applied,
this value is considered:
A) Information
B) Knowledge
C) Wisdom
D) Data
Answer: D) Data
Rationale: Data are discrete, objective facts or measurements without
interpretation. The blood pressure reading becomes "Information" only once it is
interpreted against normal values or trends.
2. A nursing informatics specialist analyzes a spreadsheet of hospital fall rates to
identify trends and patterns related to specific times of day. This synthesis of
data to identify relationships represents the transformation of data into:
A) Wisdom
B) Raw facts
C) Knowledge
D) Input
Answer: C) Knowledge
Rationale: Knowledge is created when information is synthesized so that
relationships are identified and formalized.
3. A charge nurse overrides a medication alert because the patient's specific
clinical presentation indicates the alert is a false positive. This decision-making
process best exemplifies:
pg. 1
,2
A) Data acquisition
B) Information processing
C) Wisdom
D) Raw data storage
Answer: C) Wisdom
Rationale: Wisdom is the appropriate use of knowledge to manage and solve
human problems, such as recognizing the exception to a clinical rule.
4. Which of the following best describes the role of the "Decoder" in Shannon &
Weaver's Mathematical Model of communication?
A) The sender who initiates the message
B) The medium used to send the message
C) The machine or person who converts signals back into a message
D) The final destination of the message
Answer: C) The machine or person who converts signals or binary data back
into a message
Rationale: The Encoder sends the signal via a Channel; the Decoder translates the
signal back into a comprehensible message for the Destination.
5. What is Nursing Informatics?
A) The study of computer hardware
B) A specialty that integrates nursing science with multiple informational and
analytical sciences to identify, define, manage, and communicate data,
information, knowledge, and wisdom in nursing practice
C) The practice of medical billing and coding
D) The management of hospital finances
Answer: B)
Rationale: This is the ANA-accepted definition of nursing informatics.
6. What is the correct order of the DIKW Metaparadigm?
A) Wisdom → Information → Knowledge → Data
pg. 2
,3
B) Knowledge → Data → Information → Wisdom
C) Data → Information → Knowledge → Wisdom
D) Information → Knowledge → Data → Wisdom
Answer: C) Data → Information → Knowledge → Wisdom
Rationale: The DIKW framework represents the continuum from raw facts (Data)
through interpretation (Information), synthesis (Knowledge), and appropriate
application (Wisdom).
7. Data is defined as:
A) Information that has been synthesized to identify relationships
B) Discrete entities that are described objectively without interpretation
C) The appropriate use of knowledge to solve problems
D) Organized patterns of information
Answer: B)
Rationale: Data are raw, uninterpreted facts or measurements.
8. Information is defined as:
A) Raw, uninterpreted facts
B) Data that has been interpreted, organized, or structured
C) The ultimate context and frame of reference
D) Discrete entities described objectively
Answer: B)
Rationale: Information is data that has been processed, interpreted, or organized
to give it meaning.
9. Knowledge is defined as:
A) Raw, objective facts
B) Information that is synthesized so that relationships are identified and
formalized
C) The appropriate application of wisdom
D) Data entered into a spreadsheet
pg. 3
, 4
Answer: B)
Rationale: Knowledge involves synthesizing multiple sources of information to
create conceptual frameworks, theories, and axioms.
10. Wisdom is defined as:
A) A collection of data points
B) Interpreted data organized into a structure
C) Appropriate use of knowledge to manage and solve human problems
D) The systematic study of information
Answer: C)
Rationale: Wisdom represents the highest level of the DIKW continuum—the
application of knowledge with ethical consideration and clinical judgment.
11. Which of the following are Tenets of Nursing Informatics? (Select all that
apply)
A) Has a unique body of knowledge aligned with the nursing profession
B) Involves synthesis of data and information into knowledge and wisdom
C) Supports decision-making in all roles and settings
D) Promotes data integrity and the access/exchange of health data
E) Incorporates key ethical concerns such as advocacy, privacy, and confidentiality
Answer: A, B, C, D, E (All of the above)
Rationale: These are the core tenets of nursing informatics practice as outlined by
ANA standards.
12. The Standards of Practice for Nursing Informatics include which of the
following?
A) Assessment, Diagnosis/Problem Identification, Outcomes Identification,
Planning, Implementation, Evaluation
B) Only Assessment and Evaluation
C) Only Planning and Implementation
D) Only Documentation and Billing
