NUR 404 Exam Test 2 Questions with Correct
Answers -2024 Update.
epidemiology-Correct Answer-patterns of health events in populations and factors which
influence distribution
use this information to control health problems
incidence-Correct Answer-number of new cases
prevalence-Correct Answer-number of actual cases -- both old and new
mortality-Correct Answer-the number of deaths occurring in the specified group is divided
by the population at risk
agent-Correct Answer-an animate or inanimate factor that must be present or lacking for a
disease or condition to develop
cause of the disease // bacteria, toxic chemical, radiation, heat, cold
host-Correct Answer-a living species (animal or human) capable of being infected or

according to person (who), place (where), time (when)
analytical epidemiology-Correct Answer-focus on investigation of causes and association
(etiology)
How and Why of disease cause
cohort, case control, cross-sectional-Correct Answer-Observational Analytic
Epidemiology studies contains what 3 domains:
cohort-Correct Answer-aka "incidence"
comes closes to the idea of a natural experiment
group of people who share same characteristic of interest and followed over time for
outcome observation
"group of people with something in common"
case control-Correct Answer-known to have the outcome of interest (cases) OR known
not too ave the outcome (control)
