NUR 401 EXAM 3 | COMPREHENSIVE NURSING STUDY GUIDE, PRACTICE
QUESTIONS & ANSWERS 2026/2027
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
