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.
Cognitive Level: Application REF: p. 154
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.
: Cognitive Level: Application REF: p. 157
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.
: Cognitive Level: Synthesis REF: p. 158
6. A nurse is concerned about the high incidence of STDs in the community college

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.
: Cognitive Level: Synthesis REF: p. 158
7. Between the years of 2000 and 2005, 1000 of 10,000 young women ages 17 to 20
