Domain 1: Epidemiology & Disease Prevention (Questions 1–15)
1. A community health nurse is conducting a community diagnosis. Which of
the following actions is the nurse performing?
A. Administering flu shots at a local pharmacy
B. Prioritizing the health needs of the community
C. Evaluating the cost-effectiveness of a diabetes program
D. Providing bedside care to a client with pneumonia
Correct Answer: B
Rationale: A community nursing diagnosis involves synthesizing assessment data to
prioritize the collective health needs of a population or community. Option A is an
intervention; Option C is evaluation; Option D is individual care.
2. A nurse is calculating the number of new cases of West Nile virus reported in
the county last month. Which term accurately describes this measure?
A. Prevalence
B. Attack rate
C. Incidence
D. Morbidity rate
Correct Answer: C
Rationale: Incidence refers specifically to the number of new cases occurring in a
,defined population during a specified time period. Prevalence includes both new
and existing cases.
3. A school nurse identifies a child with pediculosis (head lice). This finding is
classified under which level of prevention?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Health promotion
Correct Answer: B
Rationale: Secondary prevention focuses on early detection and prompt
intervention to halt the disease process. Screening for lice allows for immediate
treatment, preventing spread to others.
4. A nurse is teaching a group of teenagers about the dangers of vaping and
strategies to avoid peer pressure. This activity is best described as:
A. Tertiary prevention
B. Secondary prevention
C. Primary prevention
D. Rehabilitation
Correct Answer: C
Rationale: Primary prevention aims to prevent disease or injury before it occurs.
Education and health promotion are classic examples of primary prevention.
5. A nurse is analyzing the "Epidemiological Triangle" for a tuberculosis
outbreak. The bacterium Mycobacterium tuberculosis represents which
component?
A. Host
B. Agent
C. Environment
D. Vector
Correct Answer: B
Rationale: The Agent is the cause of the disease (the microorganism). The Host is the
human who gets sick; the Environment is the external factors allowing transmission.
6. Which of the following is an example of tertiary prevention?
A. Providing a smoking cessation class
B. Administering vaccines to infants
C. Teaching a client with diabetes how to perform foot care
D. Conducting a community blood pressure screening
, Correct Answer: C
Rationale: Tertiary prevention aims to soften the impact of an ongoing illness by
managing complications and improving quality of life. Foot care in a diabetic client
prevents ulcers/amputation.
7. A nurse reports that the infant mortality rate in a specific zip code is 12.5 per
1,000 live births. This data is classified as:
A. Morbidity indicator
B. Mortality indicator
C. Demographic data
D. Socioeconomic indicator
Correct Answer: B
Rationale: Infant mortality is a standard Mortality Indicator (death rate). It reflects
the overall health status and maternal-child health access in a community.
8. A community health nurse is addressing the Healthy People 2030 objective of
reducing the rate of new HIV infections. This is an example of:
A. Secondary prevention
B. Tertiary prevention
C. Primary prevention
D. Treatment
Correct Answer: C
Rationale: Reducing the rate of new infections falls under primary prevention
(preventing the onset of disease), whereas treating existing HIV is tertiary.
9. Which study design provides the strongest evidence for causality in
community health interventions?
A. Cross-sectional study
B. Case series
C. Randomized Controlled Trial (RCT)
D. Ecological study
Correct Answer: C
Rationale: The RCT is the gold standard because randomization minimizes bias,
providing the highest level of evidence for cause-and-effect relationships.
10. A nurse screens all children in a clinic for lead poisoning. The nurse explains
that screening is particularly important for children living in homes built before
which year?
A. 1960
B. 1978
