NSG 522 EXAM 1 QUESTIONS WITH COMPLETE
SOLUTIONS
'latent' stage Correct Answers The period between exposure and
infection is called 'latent period', since the pathogen is present in
a 'latent' stage, without clinical symptoms or signs of infection in
the host.
5 W of epidemiology: Correct Answers What is the health
related state such as the disease
Who describes the person that are affected by the health event
Where is the place that it occured
When is the time
Why is all about the cause
Age of degenerative and man-made disease Correct Answers
where mortality was low and life expectancy was greater than 50
years
because we control chronic diseases better
Age of pestilence and famine Correct Answers where mortality
was high and life expectancy was 20-40 years
Age of receding pandemics Correct Answers where the
mortality started to decline and life expectancy was 30-50 years
because we starting to control infectious diseases
Airborne transmission: Correct Answers Occurs when droplets
or dust particles carry the pathogen to the host and cause
infection.
, This may result when a person sneezes, coughs, or talks,
spraying microscopic pathogen-carrying droplets into the air that
can be breathed in by nearby susceptible hosts.
It also occurs when droplets are carried through a building's
heating or air-conditioning ducts or are spread by fans
throughout a building or complex of buildings
Example-respiratory viruses, pertussis, pneumococcal
pneumonia, diphtheria, rubella
Analytic Correct Answers looks at the cause, what can we learn
about causeul relationships.
Determinants and the causal factors looking at the how and why.
Analytic studies Correct Answers randomized trials, cohort
studies
Biological transmission: Correct Answers When the pathogen
undergoes changes as part of its life cycle while within the
host/vector and before being transmitted to the new host.
Example-malaria when the female Anopheles mosquitoes blood
meal is required for the Plasmodium protozoan parasite to
complete its sexual development cycle.
Biostatics Correct Answers Is the use of statistics of biological
phenomenon. Enables us to test a hypothesis to determine
whether there are associations between exposure and outcomes
and differences between groups
CDC mission Correct Answers Is to protect the health, safety,
and security threats of the country from both foreign and in the
U.S. in order to increase the health security of the nation.
