Epidemiological Applications Chapter 9 Exam
Questions And Answers
1. For which of the following types of projects would the nurse be primarily using
analytic epidemiology as a tool?
a. Communicable disease statistics
b. Contributing factors to childhood obesity
c. Determining locations where family violence is increasing
d. Documenting population characteristics for healthy older citizens - ANSWER : B
Epidemiology has been described as related not only to infectious epidemics but also to
other health-related events. Analytic epidemiology examines the etiology (origins or
causes) of disease.
: Knowledge Level REF: p. 151
2. The nurse is working as a nurse epidemiologist in which of the following roles?
a. Obtaining the health history of a client who comes to the facility for treatment of an
illness
b. Studying the number of clients who come to the facility with diseases that share
common causes
c. Performing a physical examination on an ill client
d. Providing treatment and health teaching to a client who has a disease - ANWER : B
Epidemiology is the study of disease as it relates to populations, whereas clinical
medicine concerns the diagnosis and treatment of disease in individuals. Epidemiology
monitors the health of a population.

, 3. Why could Florence Nightingale be considered an epidemiologist?
a. She encouraged other women to join her in providing nursing care to all of the
soldiers.
b. She was able to demonstrate that by making the environment safer, the mortality rate
improved.
c. She secured safe water and more adequate food supplies and battled the lice and
rats.
d. She visited each soldier every night to bid them goodnight, thus providing mental
comfort. - ANSWER : B
Nightingale studied the correlation between the environment and the recovery of the
soldiers. She was able to show that improvement in environmental conditions coupled
with the addition of nursing care reduced mortality rates for the soldiers through the use
of simple epidemiologic measures. Nightingale utilized statistics to document the
decreased rates of mortality when environmental factors had been improved.

4. In what way is nursing in the community more challenging than nursing in an acute
care setting?
a. There is limited access to information useful to the nurse in giving care in the
community.
b. More paperwork and forms are required when giving care in the home.
c. It is more challenging to control the environment in the community.
d. Specialization isn't possible in the community setting. - ANSWER : C
Epidemiology is used more often in the community due to nurses being unable to as
easily control the factors, which affect the individual, family and population group as in
acute care settings. In fact, it is virtually impossible to control the environment in the
community.

5. Several small communities requested help from the state department of health in an
effort to improve their teen pregnancy rate. Which community would the nurse
recommend receive funding first?
, a. Community A—with 23 single teenage pregnancies in a city of 500
b. Community B—with 45 single teenage pregnancies in a city of 1000
c. Community C—with 90 single teenage pregnancies in a city of 2000
d. Community D—with 90 single teenage pregnancies in a city of 1500 - ANSWER : D
Without doing any actual math, it should be fairly obvious that 23:500, 45:1000, and
90:2000 are all about the same proportion but that 90:1500 is a larger proportion. Doing
the math, the pregnancy rates of A, B, and C are 45-46:1000, whereas the rate in
Community D is 60:1000.

6. A nurse is concerned about the high incidence of STDs in the community college
population and establishes a special STD screening. Which students would not be
encouraged to attend?
a. Sexually active students currently being treated for an STD
b. Sexually active students who had been screened the previous year
c. Those students who reported not being sexually active and not planning to become
sexually active
d. Those students who are sexually active but never "go all the way" - ANSWER : A
Those who have already been diagnosed with the problem cannot be considered at risk
because they already have the condition and thus cannot be considered at risk for its
development.

7. Between the years of 2000 and 2005, 1000 of 10,000 young women ages 17 to 20
years at a university tested positive for an STI. Of the 1000 identified STIs, 300 were
gonorrhea and 500 were chlamydia. How could this STI problem be summarized?
a. The ratio of cases of gonorrhea to all STIs was 300:1300.
b. The ratio of cases of gonorrhea to chlamydia was 300:500.
c. The cases of gonorrhea were half of all the STIs.
d. The ratio was between STI cases and the total population is 100:1000. - ANWER : D
