A description of health-related patterns in a population should take into account which information?
a) The size of the population at risk during a specified time period
b) The annual number of cases of the health-related event
c) The ratio of the number of cases to the frequency of the health event

between exposure and outcome?

b) Cohort studies
c) Cross-sectional studies
d) Ecological studies - ANS-d
A business executive develops symptoms of the flu one day after returning by air from a cross-Atlantic
business trip that ran for two consecutive, stressful 10-hour days. What relationships are illustrated by
this development of flu symptoms?
a) Person, place, and time
b) Host, agent, and environment
c) Risk and causality
d) Morbidity and disease - ANS-b
Nurses in community health often use epidemiology because in the community, it is often difficult to
control the environment. Which statement demonstrates an epidemiological strategy for monitoring
disease trends?
a) A community health nurse (CHN) conducts a diabetic education class for newly diagnosed clients.
b) A CHN investigates reported cases of whooping cough in an elementary school.
c) A CHN organizes a health and wellness fair at the community health centre.
d) A CHN participates on a county school board that addresses student health issues. - ANS-b
, A CHN teaches a client with asthma to recognize and avoid exposure to asthma triggers and assists the
family in implementing specific protection strategies, such as removing carpets and avoiding pets. What
level of intervention is represented by this practice?
a) Assessment
b) Primary prevention
c) Secondary prevention
d) Tertiary prevention - ANS-b
Who was historically described as the "father of epidemiology?"
a) Lambeth
b) Lister
c) Koch
d) Snow - ANS-d
A breast cancer screening program screened 8 000 women and discovered cancer in 35 women who had
previously been diagnosed with breast cancer and in 20 women with no previous history of breast
cancer. What is the prevalence rate of breast cancer in this scenario?
a) Current and past breast cancer events in this population of women
b) Newly diagnosed cases of breast cancer in this population of women
c) Past breast cancer events in this population of women
d) Population of women who had no evidence of breast cancer - ANS-a
One of the basic concepts in epidemiology is the concept of risk. How is risk can be defined?
a) The prevalence of an event occurring over a lifetime.
b) The probability that an event will occur within a specified time period.
c) The proportion of the population that will develop an event.
d) The rate of development of new cases. - ANS-b
Twenty people attended a church picnic on the weekend. By Monday, four individuals exhibited
symptoms of food poisoning. On Tuesday, the CHN records the addition of two new cases. What is the
incidence rate for this occurrence?
a) Two new cases divided by 16 at risk
b) Two new cases divided by 20 at risk
c) Six cases divided by 20 at risk
d) Four cases divided by 16 at risk - ANS-a
An incidence rate quantifies the rate of development of new cases in a population at risk (persons
without the event or outcome of interest but who have a chance of experiencing it).
Which epidemiological approach is criticized because it takes a narrow view and limits findings by
studying individuals, rather than studying the environment and societal influences where the risks often
begin?
a) Life course approach
b) Natural history of disease
c) Risk-factor approach
d) Web of causality - ANS-c
Which test measure is affected by the prevalence of disease in the screened population?
