WGU C790 EXAM 3 REVIEW SOLVED
QUESTIONS WITH ACCURATE ANSWERS
◉ Knowledge Transformation.
Answer: (Ace Star Model)
is defined as the conversion of research findings from discovery of
primary research results, through a series of stages and forms, to
increase the relevance, accessibility, and utility of evidence at the
point of care to improve healthcare and health outcomes by way of
evidence-based care.
◉ Ace Star Model.
Answer: These five points are discovery research, evidence
summary, translation to guidelines, practice integration, and
evaluation of process and outcome
◉ clinical practice guidelines (CPGs).
Answer: The IOM defines clinical guidelines as "systematically
developed statements to assist practitioner and patient decisions
about appropriate health care for specific clinical circumstances.
◉ usability.
Answer: 1.Increased user productivity and efficiency 2.Decreased
user errors and increased safety 3.Improved cognitive support
,◉ human factors.
Answer: is "the scientific discipline concerned with the
understanding of interactions among humans and other elements of
a system, and the profession that applies theory, principles, data and
methods to design in order to optimize human well-being and
overall system performance."
In healthcare, human factors might concern the design of a new
operating room to better support teamwork and patient flow.
◉ ergonomics.
Answer: used interchangeably with human factors by the HFES in
Europe but in the U.S. and other countries its focus is on human
performance with physical characteristics of tools, systems, and
machines
i.e. power drill fitting in hand
◉ Human-computer interaction (HCI).
Answer: is the study of how people design, implement, and evaluate
interactive computer systems in the context of users' tasks and work
◉ usability.
,Answer: is often used interchangeably with HCI when the product is
a computer but usability also concerns products beyond computers.
Usability is also more focused on interactions within a specific
context or environment for a specific product.
Formally, the ISO defines usability as the extent to which a product
can be used by specific users in a specific context to achieve specific
goals with effectiveness, efficiency, and satisfaction.
allows users to achieve goals
◉ joint cognitive systems.
Answer: imply that information is shared or distributed among
humans and technology. This framework is useful for examining
teamwork in healthcare where team members work together on
patient care
◉ Health Human-Computer Interaction (HHCI) Framework.
Answer: Humans or products can initiate interactions. The
information is processed through either the product or the humans
according to characteristics. The recipient then reacts to the
information; for example, a healthcare provider could read and
respond to email from a patient or a product might process
interactions after the "enter" key is pressed. Iterative cycles continue
as humans behave and products act according to defined
, characteristics. Goals and planning are implicit within the tasks
displayed in the framework.
◉ discount usability methods.
Answer: reduce the number of required users in usability projects
and to use early design prototypes.
These methods offer economies of time, effort, and cost and can be
completed at any point in the systems life cycle.
Two common techniques are heuristic evaluation and think-aloud
protocol.
◉ Heuristic evaluations.
Answer: compare products against accepted usability guidelines to
reveal major and minor usability issues.
◉ think-aloud protocol.
Answer: also involves a small number of users and has them talk
aloud while they interact with a product. Users voice what they are
trying to do, indicate where interactions are confusing, and provide
other thoughts about the product during interactions.
