NR503 Epidemiology Midterm Study Guide
NR 503 Midterm Exam Study Guide: Chamberlain College of Nursing
• 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 screeningtest
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?
