NR 503 Exam Questions With Complete Solutions
5 W's of descriptive epidemiology Correct Answer What,
Who, Where, When, Why/How
Age Correct Answer single most important "person" attribute
Aggregate Correct Answer defined population
Campaign for Action Correct Answer Transforming health
care through nursing. Goals are based on IOM. Future of nursing
report works on 7 major interrelated issues
Case Control study Correct Answer investigator identifies a
group of individuals with the attribute of interest (case) and
compares to a group without the attribute of interest (control).
Retrospective
Case Control study strengths Correct Answer inexpensive,
relatively quick, able to study variables with long latency or
impact period, able to calculate odds ratio, able to study rare or
fatal diseases, can study multiple exposures
Case control study weaknesses Correct Answer risk of bias
and confounding variables, sometimes unable to measure or
determine exposure, selection bias, measurement error, recall
bias, cannot assess risk
Case fatality rates Correct Answer measure of severity of
disease (infectious diseases). Not a true rate, is the measurement
, of the probability of death among diagnosed cases. Helps
determine when to use a screening tool.

Cohort Study Correct Answer Can be prospective or
retrospective. Selects a group of exposed individuals and
compares to nonexposed individuals
Cohort study strengths Correct Answer able to identify
confounding variables, able to control exposure, able to
calculate relative risk and attributable risk, can study multiple
outcomes
Cohort study weaknesses Correct Answer labor intensive,
costly, lengthy
