HS Informatics Exam 1 Review
Dr. James, in studying patient safety in U.S. hospitals, found that the number of preventable
adverse events leading to serious harm fell in the range of: ans: 4.4 to 8.8 million
Informatics is both a _____ and a _____ ans: Profession; discipline
The top three uses of the U.S. Army's telehealth network include all of these, *except*: ans:
otolaryngology
What is the main idea of the subsection titled "Why Informatics Is Needed in Healthcare"?
ans: An interoperable healthcare system that provides clear, concise patient data and
information among institutions is lacking in many facilities, and its presence would greatly
facilitate things such as patient transfers.
The text makes the argument for increased automation for such things as managing
supplies because studies have shown that: ans: Nurses waste an hour a shift finding
equipment
(T/F) The SDLC is the oldest and widely used methods for building and implementing
software application in IT arena. ans: True
Which of the following about EHR's is *FALSE*? ans: By 2014, 50% of physicians in the
United States had implemented an EHR with another 13% in the process of implementing
one.
Internationally, healthcare delivery systems face a number of common challenges
*including*: (select all that apply)
a) Cut costs & demonstrate value
b) A lack of new HIT advances
c) Dynamic forces like workforce shortages and increased consumerism
d) An international population that is growing increasingly younger and healthier
e) Increasing government regulations to protect patient health safety & privacy. ans: a) Cut
costs & demonstrate value
c) Dynamic forces like workforce shortages and increased consumerism
e) Increasing government regulations to protect patient health safety & privacy.
, The *primary* difference between an open and a closed system ans: An open system has a
semi-permeable boundary and therefore will filter both inputs and outputs when interacting
with the environment.
The *primary* characteristics used to analyze an open system include: ans: - Structure
- Purpose
- Functions
You've altered the menu of food items served to your patients, however the change has
greatly expanded the number of refrigerated items needed on hand. You need to buy a new
refrigerator , but the electric circuit in the kitchen cannot handle the extra load and needs to
be upgraded at a significant expense. *The set of unattended consequences down the line
produced by an initial change is called*: ans: Reverberation
The "butterfly effect" describes a situation in which a minor change in input (e.g., a butterfly
flapping its wings in one part of the world) can have a major effect on output (e.g., a
windstorm developing in another part of the world). This aspect of chaotic systems
illustrates their property of:
a) The reiterative feedback loop.
b) Linearity.
c) Preordained periodic behavior.
d) The fractionation of outputs. ans: a) The reiterative feedback loop.
Which statement describes the measurement of information as defined by the Shannon and
Weaver model? ans: The amount of information is measured by the extent the message
decreases entropy.
On its own, the number 190 is an example of:
a) Data
b) Information
c) Knowledge
d) Wisdom ans: a.) Data
What are the three general types of learned behavior? ans: - Cognitive
- Affective
- Psychomotor
