COMMUNITY HEALTH UPDATED SET ANSWERS AND
QUESTIONS SET A+
✔✔Transmission of an infectious disease can be efficiently controlled by
a. breaking all links in the transmission chain.
b. destroying all reservoirs of infectious agents.
c. breaking only one link in the transmission chain.
d. maintaining high levels of herd immunity. - ✔✔c. breaking only one link in the
transmission chain.
Breaking just one link of the chain can control transmission of an infectious agent.
Destroying all reservoirs of infectious agents and maintaining high levels of herd
immunity are two of several ways to break a link in the chain of transmission.
✔✔Which is classified as a vector of disease?
a. Humans
b. Door handles
c. Water and food
d. Mosquitoes - ✔✔d. Mosquitoes
Vectors can be animals or arthropods and can transmit disease through biological and
mechanical routes. The other options are not vectors.
✔✔A pathogen lives and multiplies in a __________ and transfers from one host to
another by a __________.
a. host, susceptible portal of entry
b. reservoir, mode of transmission
c. infectious agent, portal of exit
d. mode of transmission, reservoir - ✔✔b. reservoir, mode of transmission
✔✔Seven cases of hepatitis A are diagnosed in a community over a period of 2 weeks.
An investigation results in a determination that all of the infected individuals ate at a
, local restaurant. Which statement explains the possible connection between hepatitis A
and a restaurant?
a. The route of transmission for hepatitis A is fecal-oral.
b. A food worker likely coughed on the customers.
c. A food worker may have a bleeding wound.
d. Hepatitis A is transmitted where people congregate. - ✔✔a. The route of transmission
for hepatitis A is fecal-oral.
✔✔Which factors cause primary vaccine failure? (Select all that apply.)
a. Inefficient storage
b. An intramuscular vaccine injection given subcutaneously
c. Waning immunity in immunocompromised patients
d. Light-sensitive vaccines exposed to light
e. Seroconversion - ✔✔a. Inefficient storage
b. An intramuscular vaccine injection given subcutaneously
d. Light-sensitive vaccines exposed to light
e. Seroconversion
Primary vaccine failure is the failure of a vaccine to stimulate any immune response. It
can be caused by improper storage that renders the vaccines ineffective, an improper
administration route, or light-sensitive vaccines exposed to light. Additionally, some
immunized persons never seroconvert, either because of failure of their own immune
system or for some other unknown reason. Secondary vaccine failure is the waning of
immunity after an initial immune response.
✔✔In which historical age would people have had an increased risk for contracting
salmonella, anthrax, Q fever, or tuberculosis from the proximity of domesticated animals
and herds?
a. Hunting and gathering stage
b. Settled village stage
c. Preindustrial cities stage
d. Industrial cities stage - ✔✔b. Settled village stage
✔✔During the Renaissance period, much was learned about health and disease. The
Elizabethan Poor Law was enacted during this time to
a. govern personal and community hygiene such as contagion, disinfection, and
sanitation.
b. make local church parishes responsible for caring for the poor in the community.
c. enforce hygienic codes from Leviticus and establish leper houses.
d. legislate social reform, addressing issues such as child welfare and factory
management. - ✔✔d. legislate social reform, addressing issues such as child welfare
and factory management.
✔✔Edwin Chadwick's Report on an Inquiry into the Sanitary Conditions of the Laboring
