Nursing NUR401 Exam 3 – Practice Questions and Answers Study Guide
What is Surveillance? - ANS ✔✔Surveillance - mechanism for the ongoing collection of
community health
information
Why is surveillance important? - ANS ✔✔It is important because it is monitoring for changes in
disease
frequency to ensure effectiveness and responsiveness in public health programs. It helps with
early detection and responds to health threats. It can help monitor disease trends and patterns.
How do we use surveillance in public health nursing? - ANS ✔✔It involves systematic collection,
analysis, and interpretation of health
data. It helps monitor disease trends and outbreaks. It improves disease prevention and control
and identifies vulnerable populations and health disparities.
What is epidemiology? - ANS ✔✔Epidemiology - the study of the distribution and determinants
of health
and disease in human populations
Why is epidemiology important? - ANS ✔✔It is important because it helps identify the exposure
or sources
that is causing the disease, finding the number of people who were potentially exposed,
reducing of further spread in the community, and creating interventions to prevent additional
cases of occurrences
How do we use epidemiology in public health nursing? - ANS ✔✔Public health nurses use
epidemiology by investigating and analyzing health problems and developing evidence-based
interventions.
, Morbidity - ANS ✔✔the likelihood of catching the disease
Mortality - ANS ✔✔the likelihood of dying from a disease
Incidence - ANS ✔✔newly diagnosed only
Prevalence - ANS ✔✔new cases and pre-existing cases
Multicausation - ANS ✔✔Multiple causes to a disease. The epidemiological triad is a perfect
example of multicausation. It requires a host, environment, and agent.
Spectrum of infection - ANS ✔✔Not all contact with an infectious agent leads to infection, and
not all infection leads to an infectious disease.
Latent Period - ANS ✔✔An infectious agent that has invaded a host and found conditions
hospitable will replicate until it can be shed fron a host
The period of replication before shedding
Happens before communicable
period
EXAMPLE: TB can be in someone and replicate for years but not spreadable until active.
Communicable Period - ANS ✔✔Follows latency
