Read All Instructions Carefully and Answer All the
Questions Correctly Good Luck: -
Epidemiology - Answer>> The science of public health
Population Health - Answer>> Focuses on risk, data,
demographics, and outcomes
How does a provider determine the usefulness,
appropriateness, of a screening test? Where would and
NP look to find a screening test? What determines if a
screening test should be used? - Answer>>
Determining whether a screening test is appropriate
requires the APRN to address several aspects of the
disease of interest. The target population needs to be
identifiable. There should be enough people to make
the study cost effective. The preclinical period should
be proficient to allow treatment before symptoms
appear so that early diagnosis and treatment make a
difference in terms of outcomes. The NP could look at
the U.S. Preventative Services Task Force, Agency for
Healthcare Research and Quality, and SAMHSA-HRSA to
find a screening test. Sensitivity and specificity
measure the validity of a test. Sensitivity is the number
identified/ the number affected. Specificity is the
number identified in the screening of not having the
disease/ the actual number who do not have the
disease.

, Can you explain what "descriptive epidemiology"
means? What is the purpose? How is it used? -
Answer>> It covers time place and person.
First, by looking at the data carefully, the
epidemiologist becomes very familiar with the data. He
or she can see what the data can or cannot reveal
based on the variables available, its limitations (for
example, the number of records with missing
information for each important variable), and its
eccentricities (for example, all cases range in age from
2 months to 6 years, plus one 17-year-old.).
Second, the epidemiologist learns the extent and
pattern of the public health problem being investigated
— which months, which neighborhoods, and which
groups of people have the most and least cases.
Third, the epidemiologist creates a detailed description
of the health of a population that can be easily
communicated with tables, graphs, and maps.
Fourth, the epidemiologist can identify areas or groups
within the population that have high rates of disease.
This information in turn provides important clues to the
causes of the disease, and these clues can be turned
into testable hypotheses.
How are causation and descriptive epidemiology
related, how do they work together to aid evidence-
based care? - Answer>> ______________- helps look at
the cause of the issue or disease process. ________
________ focuses on the person, place, and time. An
example of how they are intertwined might be a person
who was sick from E. Coli. The physician might look at
what the individual ate to determine what made them
sick. For instance, they may have decided to eat from
the salad bar at a local restaurant.
