NR 503 Week 4 Midterm Exam Study guide
NR 503: Population Health, Epidemiology & Statistical
Principles
, Week 1
How does social justice and health inequities influence population health
care provision? Why is this critical information for the provision of
evidence-based care?
Population-based nursing is the provision of evidence-based care to
targeted groups of people with similar needs in order to improve health, or
stated otherwise, to improve health. In order to provide this care providers
must consider health inequities and social justice in order to improve
health care for all people. Population health is typically interested in high
risk aggregates(subpopulations) which means looking at those health
inequities and using social justice theory to integrate health promotion and
disease prevention interventions for those high risk aggregates.

1. Is screening a tertiary intervention? If yes, why, if not, what is it?
No. Screening are a secondary intervention. Tertiary interventions focus on
alleviating disability and are strategies done in middle or late stages of diseases.
An example of a tertiary intervention would be cardiac rehab or physical therapy
after a hip replacement
2. How does a provider determine the usefulness, appropriateness, of a screening
test? Where would a NP look to find a screening test? What determines if a
screening test should be used?
The target population needs to be identifiable and accessible and the disease
should affect a sufficient number of people. The screening test should be
sensitive enough to detect most cases and be specific enough to limit the
number of false positives. Screening tests should be relatively inexpensive, easy
to administer, and have minimal side effects. The validity of the screening test is
the ability to accurately identify those that have the disease.
Determining if a screening test should be used can be evaluated by the success
of a screening tool. Does the screening tool do what it was intended to do and
reduce overall mortality, decrease case fatality, increase early detection, reduce
complications or increase quality of life?
APNs can look for screening test through the U.S Preventative Services Task
3. Can you explain what “descriptive epidemiology” means? What is the purpose?
How is it used?
