Question 1
2 out of 2 points
Which statement describes the measurement of information as defined
by the Shannon and Weaver model?
Selected Answer:
d. The amount of information is measured by the extent the message
decreases entropy.
Response Feedback: By decreasing entropy one decreases uncertainty.
Shannon, a telephone engineer, sought to overcome the technical
problems of moving information across communication channels by
determining how to minimize entropy.
Question 2
2 out of 2 points
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
approximate range of ____________ to _____________ cases per year.
Selected Answer:
c. 4.4 million; 8.8 million
Response Feedback: Dr. James found some 440,000 cases of lethal
harm each year and estimated that the incidence of serious (but not
lethal) harm was 10 to 20 times that figure.

, INFO 305 Quiz 1
The “butterfly effect” describes a situation in which a minor change in
input (eg, a butterfly flapping its wings in one part of the world) can
have a major effect on output (eg, a windstorm developing in another
part of the world). This aspect of chaotic systems illustrates their
property of:
Selected Answer:
d. the reiterative feedback loop.
Response Feedback: Chaotic systems are dynamic systems with
reiterative feedback loops. A minor change in input can create a major
change in output. This is often described as the butterfly effect. A
butterfly’s flapping wings in California can over time become a
hurricane in New York.
Question 4
2 out of 2 points
Which of the following is not a member organization but rather a group
of organizations?
Selected Answer:
d. ANI
Response Feedback: The Alliance for Nursing Informatics (ANI) is an
organization of organizations. This is not a member group. AMIA,
HIMSS, and AHIMA are all member groups.
Question 5

____________.
