NR 503 CHAMBERLAIN MIDTERM ANABELL QUESTIONS
AND ANSWER REVIEWED AND VERIFIED 2026
Epidemiology - correct answers is the science of public health
Population Health - correct answers focuses on risk, data, demographics, and outcomes.
Outcomes - correct answers is the end result that follows an intervention
aggregate - correct answers is a defined population.
community - correct answers is composed of multiple aggregates
data - correct answers is complied information
Prevalence - correct answers measures the existence of a disease. Measures the number of all
cases of a disease or attribute in a population at a given time
Incidence - correct answers measures the appearance of a disease. Measures the occurrence of
new events in a population over a period of time.
surveillance - correct answers is the collection, analysis, and dissemination of data.
,high-risk - correct answers is an increased chance of poor health outcome.
Morbidity - correct answers is the presence of illness in a population
mortality - correct answers is related to the tracking deaths in an aggregate
vital statistics - correct answers statistics on live births, deaths, fetal deaths, marriages and
divorces.
cases - correct answers set of criteria used in making a decision as to whether an individual has
a disease or health event of interest
Social Justice - correct answers the view that everyone deserves equal rights and opportunities
—this includes the right to good health
Inter-professional collaboration - correct answers The idea of sharing and implies collective
action oriented toward a common goal, in this case, improving the quality and safety of patient
care. It involves responsibility, accountability, coordination, communication, cooperation,
assertiveness, mutual respect, and autonomy.
Healthy People 2020 - correct answers aims to reach four overarching goals: 1.Attain high-
quality, longer lives free of preventable disease, disability, injury, and premature death, 2.
Achieve health equity, eliminate disparities, and improve the health of all groups 3.Create social
and physical environments that promote good health for all. 4. Promote quality of life, healthy
development, and healthy behaviors across all life stages.
Determinants of care/health - correct answers The range of personal, social, economic, and
environmental factors that influence health status are known ...
, risk analysis - correct answers the characterization of the potential adverse health effects of
human exposures to environmental hazards
health disparities - correct answers the difference in health statuses between various groups
(populations).
Sensitivity - correct answers measures the proportion of actual positives that are correctly
identified as such (e.g., the percentage of sick people who are correctly identified as having the
condition)
Specificity - correct answers (also called the true negative rate) measures the proportion of
actual negatives that are correctly identified as such (e.g., the percentage of healthy people who
are correctly identified as not having the condition)
Positive predictive value - correct answers is the probability that subjects with a positive
screening test truly have the disease
epidemiological triangle - correct answers 1. A traditional model of infectious disease causation,
known as the Epidemiological Triad is depicted in Figure 2. The triad consists of an external
agent, a host and an environment in which host and agent are brought together, causing the
disease to occur in the host.
confounding variable - correct answers is an "extra" variable that you didn't account for. They
can ruin an experiment and give you useless results. They can suggest there is correlation when
in fact there isn't. They can even introduce bias. That's why it's important to know what one is,
and how to avoid getting them into your experiment in the first place
Study Methods - correct answers descriptive and analytic
descriptive study AKA Natural history of disease - correct answers It is the first step in
epidemiology investigation. Used to describe the distribution of the disease and other health-
