NR503 -2025- EPIDEMIOLOGY MIDTERM EXAM
SET OF QUESTIONS AND CORRECT ANSWERS
ALREADY GRADED A+ GUARANTEED SUCCESS
Sensitivity
a measure of a screening test's ability to accurately identify disease when it is
present.
Specificity
a measure of a screening test's ability to correctly identify a person without disease
with a negative test.
Social Justice
the defense of human dignity by ensuring that essential human needs are met and
that essential human rights are protected for all people
Epidemiology
the study of disease distribution within populations and the risk factors that affect
increases or decreases in distribution.
Positive Predictive Value
a measure of the probability of a positive test result when the disease is present.
Population Health
health outcomes of a group of individuals, including the distribution of such
outcomes within the group
Period Prevalence Rate
measures the number of cases of disease during a specific period of time and is a
measure of burden.
Negative Predictive Value
a measure of the probability that the disease is absent when there is a negative test
, Vital Statistics
Vital statistics provide important outcome measures that APRNs can monitor and
compare over time and analyze by demographic variables to detect such things as
health disparities. In the United States, the National Center for Health Statistics
(NCHS) collects the official records of births, deaths, marriages, divorces, fetal
deaths, and induced terminations of pregnancies from state and local health
departments (Aschengrau & Seage, 2013). Personnel from local health departments
review the data from death certificates, including demographic data, looking at the
immediate cause of death and any contributing factors of death, and recording
multiple causes of death. Local data are sent to a state office for collation and then
sent to the NCHS, which provides this information to the public on its website
(http://www.cdc.gov/nchs) and in an annual publication, Vital Statistics of the
United States (Friis & Sellers, 2009). APRNs can access national and global health
statistics from multiple agency sources, including government agencies, to identify
health trends and patterns (Partners, 2014). However, due to the lack of agencies
and/or resources in certain populations or regions, health information might not be
available or might be limited in scope
Morbidity
Refers to ill health in an individual and the levels of ill health in a population or
group.
Mortality
Mortality rates, also known as death rates, can be useful when evaluating and
comparing populations. As stated earlier, there are many factors that can affect the
natural history of disease, and measuring mortality allows investigators to compare
death rates among and within populations
Cases
Refers to individuals who acquire a certain disease or condition.
Incidence
Incidence rates describe the occurrence of new events in a population over a period
of time relative to the size of the population at risk,Incidence provides information
about the rate at which new cases occur and is a measure of risk. Incidence rates
provide us with a direct measure of how often new cases occur within a particular
population and provide some basis on which to assess risk.
