NR503 Final Exam Study Notes
Chamberlain College of Nursing
• Be sure to review the terminology and concepts of the first four weeks: these concepts help to
inform and support the last four weeks of the course.
• All information listed on this review doc can be found in the course text, Gordis.
Definitions of study designs: Chapter 10: Differentiate between the case-control and cohort studies.
Ask yourself, which is used when, and why. the hallmark of the case-control study is that it begins
with people with the disease (cases) and compares them to people without the disease (controls).
cohort study, discussed in Chapter 9, which begins with a group of exposed people and compares
them to a nonexposed group. What distinguishes the two study designs is whether the study
begins with diseased and nondiseased people (case-control study) or with exposed and
nonexposed people (cohort study).
Primary, Secondary, Tertiary Prevention
What are primary (remove disease risk factors eg immunizations, exercise), secondary (early detection
and treatment eg. screening), tertiary prevention (reduce complications to reduce further deterioration
eg. Beta blockers) measures?
Case-Control:
• Examine the possible relationship of an exposure to a certain disease
• Identify group of individuals with the disease (cases)
• For comparison, gather a group of people without that disease (controls)
• Determine what proportion of the cases were exposed and were not
• Also determine what proportion of the controls were exposed and not
• Text: Thus, in a case-control study, if there is an association of an exposure with a disease, the
prevalence of history of exposure should be higher in persons who have the disease (cases)
than in those who do not have the disease (controls).
• Ask yourself: Why is this important to the NP in primary care? How does this inform a
provider’s decision-making?
