✔✔An application lacks a consistent layout and design from screen to screen. Which of
the following usability factors would be most affected by this inconsistency? -
✔✔Learnability
✔✔occurs when the user has to struggle just to navigate the interface, using up mental
energy and concentration that should be focused on the medical or clinical problem at
hand - ✔✔Cognitive strain
✔✔is evaluated by whether an application provides all the functionality necessary for
users to complete a task. - ✔✔Utility
✔✔s a field of study that is directed by concepts and principles from engineering and
applied cognitive psychology . - ✔✔Human factors
✔✔can be described as the interactions of a human with a system. It can also be
defined as the scientific study concerned with understanding how humans interact with
the various parts of a system. - ✔✔Ergonomics
✔✔What factor of selective attention describes something that is important and stands
out to an individual, while other stimuli are ignored? - ✔✔Salience
✔✔According to the factors of selective attention, humans are programmed to
recognize something that may place them in danger while filtering out other stimuli.
What is this instinctive behavior called? - ✔✔Expectancy and value
✔✔Which domain of cognitive capacity would describe a cluttered computer interface or
an instructional guide with tiny print and an index with few entries? - ✔✔Effort
✔✔is the malfunction, slip, or mistake—the accident itself—that occurs at the frontline,
which in a medical setting is often the point of care. - ✔✔Active error
, ✔✔is an error that occurs when the correct route of action was followed but was
executed incorrectly. - ✔✔A slip
✔✔occur when an incorrect action is performed because of misinterpretation or poor
judgment. - ✔✔A mistake
✔✔are failures of design, organization, training, or maintenance that lay dormant and
unnoticed until, after a period of normal operation, they trigger an active error. -
✔✔Latent errors
✔✔result from ignorance of key concepts. Incomplete knowledge, incorrect selection of
knowledge, or too much knowledge (information overload) can lead to

A.)Pilot
B.)Deliver
C.)Product test
D.)Evaluate - ✔✔A.)Pilot
When the prototype system (or systems) is tested in the hospital or clinic, it is being
piloted.
