NURS 2710 FINAL EXAM PREP QUESTIONS AND ANSWERS |
NURS 2710 STUDY GUIDE & PRACTICE TEST 2026/2027
What is epidemiology? - correct answer ✔✔the study of the distribution/occurrence of health related
events in specific populations
what is the epidemiology triangle? - correct answer ✔✔a diagram containing the host, agent, and
environment
what is meant by temporal relationship - correct answer ✔✔a criterion for causality, a person does not
get the disease until after exposure to the stressor
what is strength of association? - correct answer ✔✔exposure to a specific stressor or cause is more
likely to bring on the disease
what is meant by "dose-response" in causality - correct answer ✔✔people who are most exposed to a
contaminated food are the most ill
what is meant by specificity? - correct answer ✔✔the cause is linked to a specific disease (e.g.,
tuberculosis bacteria wont result in chicken pox)
what is consistency in regards to causality - correct answer ✔✔when everyone who eats contaminated
food gets the illness
what is biologic plausibility? - correct answer ✔✔when findings are consistent to biologic/medical
knowledge.
what is experimental replication? - correct answer ✔✔in causality, when several studies are done by
different scientists in different places produce the same or similar results
what is a mortality rate and how does it inform a CHN? - correct answer ✔✔it looks at the deaths due to
specific diseases/conditions, it may help in regard to planning areas of focus in the future
what is a morbidity rate and how is it useful for a CHN - correct answer ✔✔morbidity rates look at
people who become ill with specific diseases. they inform scientists how frequently an illness occurs
what is incidence in epidemiology? - correct answer ✔✔it is the measure of new cases of a health
condition/illness/event in a given time
what is prevalence in epidemiology? - correct answer ✔✔it is the number of people in a population who
have a health condition/illness/event at the current time
what happens when incidence and prevalence rates are similar? - correct answer ✔✔the disease is likely
to be short lived with recovery or death shortly after the diagnosis (e.g., the flu)
