WGU C790 NURSING INFORMATICS STUDY
GUIDE 2026 FULL PRACTICE EXAM
◉ AHRQ. Answer: Agency for Healthcare Research and Quality
◉ CCC. Answer: Clinical Care Classification, classification system of
nursing diagnoses and interventions for home health
◉ Change Theory. Answer: The study of change in individuals or
social systems such as organizations.
◉ Channel. Answer: A physical element that carries a message
between a sender and a receiver. Examples of channels are radio
waves, fiber optic lines, and paper.
◉ Chaos Theory. Answer: The qualitative study of unstable aperiodic
behavior in deterministic, nonlinear dynamical systems
◉ Clinical Informatics. Answer: The application of informatics and
information technology to deliver healthcare services.
◉ Closed System. Answer: A system that is enclosed in an
impermeable boundary and does not interact with the environment.
,◉ QI. Answer: quality improvement
◉ Complex Adaptive Systems (CAS). Answer: An entity consisting of
many diverse and autonomous parts that are interrelated,
interdependent, linked through many interconnections, and behave
as a unified whole in learning from experience and in adjusting to
changes in the environment
◉ Complexity Theory. Answer: Complexity theory builds on chaos
theory using a qualitative approach to the study of dynamic
nonlinear social systems that change with time and demonstrate
complex relationships.
◉ Computerized provider order entry (CPOE). Answer: A system
that automates the way that orders have traditionally been initiated
for patients. Clinicians place orders within these systems instead of
using traditional handwritten transcription onto paper. These
systems provide major safeguards by ensuring that physician orders
are legible and complete, thereby providing a level of patient safety
that was historically missing with paper-based orders. They provide
decision support and automated alert functionality that was
previously unavailable with paper-based orders.
◉ Computer science. Answer: The "systematic study of algorithmic
methods for representing and transforming information, including
, their theory, design, implementation, application, and efficiency....
The roots of computer science extend deeply into mathematics and
engineering. Mathematics imparts analysis to the field; engineering
imparts design" (University at Buffalo School of Engineering and
Applied Sciences;
◉ Needs Assessment. Answer: An assessment of needs of a
department or organization using different methods such as
surveys, interviews and report gathering.
◉ Conceptual Framework. Answer: A description and explanation of
concepts and their relationships and interactions related to a
specific phenomenon. Conceptual frameworks can be used to
propose theories and generate research questions. A conceptual
framework can also be used to develop a conceptual model.
◉ Data. Answer: Uninterpreted elements such as a person's name,
weight, or age. Because they are uninterpreted, they do not have
meaning.
◉ Data integrity. Answer: The accuracy and consistency of stored
and transmitted data. Data integrity can be compromised when
information is entered incorrectly or deliberately altered or when
the system protections are not working correctly or suddenly fail.
