When applying the epidemiologic triad model to a community's plan of care, which of
the following would the community health nurse address?
A)
Incidence, prevalence, and case fatality
B)
Health, illness, and injury
C)
Host, agent, and environment
D)
Immunity, causation, and risk
Ans:
C
Feedback:
The purpose of this model is to demonstrate the relationship among host, agent, and
environment. Each component has to be present to a certain degree in order for any
disease, illness, or injury to exist or happen. If one component is missing, illness or
injury will not occur. Incidence, prevalence, case fatality, health, illness, injury,
immunity, causation, and risk are terms used in epidemiology but do not refer to the
epidemiologic triad model.
