NSG 3480 EXAM 2 WITH QUESTIONS
AND ANSWERS WRITTEN
CORRECTLY
Epidemiology - correct answer<<<<<<<💖💖💖✔the study of the distribution and determinants of
health and disease in human population
Three Elements of the Epidemiological Triangle - correct answer<<<<<<<💖💖💖✔- Agent: actual
cause of disease
- Host: carrier of disease
- Environment: any outside factors
Use of Epidemiology in Disease Control and Prevention - correct answer<<<<<<<💖💖💖✔PERSON:
"Who" factors, such as demographic characteristics, health, and disease status
PLACE: "Where" factors, such as geographic (data) location, climate and environmental conditions, and
political and social environment
TIME: "When" factors, such as time of day, week, or month and secular trends over months and years
Wheel Model of Epidemiology - correct answer<<<<<<<💖💖💖✔The wheel model stresses the
multiplicity of host and environmental interactions have developed and understanding of disease has
progressed.
Which is better the triangle or the wheel? - correct answer<<<<<<<💖💖💖✔The Wheel Model
subscribes to multiple-causation disease theory; therefore, it is MORE USEFUL for analyzing complex
chronic conditions and identifying factors that are amendable to nursing intervention.
, Web of Causation Model - correct answer<<<<<<<💖💖💖✔In essence, the web of causation model
is better at showing the relationships among variables.
Incidence rates - correct answer<<<<<<<💖💖💖✔describe the occurrence of new cases of a disease
or condition in a community
Prevalence rate - correct answer<<<<<<<💖💖💖✔is the number of all cases of a specific disease or
condition in a population at a given point in time
Meaningful Comparisons - correct answer<<<<<<<💖💖💖✔The community nurse compares data
with rates from other cities, counties, districts, or states; from the nation; and from previous records.
*SHOWS TRENDS*
Risk - correct answer<<<<<<<💖💖💖✔probability of an adverse event
Risk factor - correct answer<<<<<<<💖💖💖✔any action or condition that increases the likelihood of
injury, disease, or other negative outcome
Descriptive Epidemiology - correct answer<<<<<<<💖💖💖✔- Focuses on the amount and
distribution of health and health problems within a population
- The purpose is to describe the characteristics of both people who are protected from disease and
those who have a disease.
Analytic Epidemiology - correct answer<<<<<<<💖💖💖✔investigates the causes of disease by
determining why a disease rate is lower in one population group than in another.
Observational Research Study - correct answer<<<<<<<💖💖💖✔discover the etiology of disease
Cross-sectional studies (Observational) - correct answer<<<<<<<💖💖💖✔sometimes called
prevalence or correlational studies, examine relationships between potential causal factors and disease
at a specific time.
