1. A community health nurse is conducting a comprehensive assessment of a local
neighborhood. Which of the following activities are considered primary data collection
methods? (Select all that apply)
A. Performing a windshield survey.
B. Interviewing key informants within the community.
C. Analyzing recent U.S. Census Bureau data.
D. Conducting focus groups with local residents.
E. Reviewing morbidity reports from the state health department.
F. Engaging in participant observation at a community center.
Correct Answer: A, B, D, F
Explanation: Primary data collection involves obtaining information directly from the
community members or through direct observation. Windshield surveys, informant
interviews, focus groups, and participant observation are all examples of primary sources.
Conversely, census data and state health reports are secondary sources because they were
previously collected by another agency for a different purpose.
,2. Which intervention should a community health nurse implement as a primary prevention
strategy to reduce the incidence of obesity in school-aged children?
A. Measuring the Body Mass Index (BMI) of all students annually.
B. Implementing a daily physical education program for all students.
C. Providing nutritional counseling to children diagnosed as overweight.
D. Referring students with metabolic syndrome to a pediatric endocrinologist.
Correct Answer: B
Explanation: Primary prevention aims to prevent the onset of disease or injury before it
occurs. Implementing a universal physical education program focuses on healthy lifestyle
promotion for the entire population to prevent obesity. Screening methods like BMI
measurements represent secondary prevention, while counseling for existing conditions
represents tertiary prevention.
3. A nurse is investigating a localized outbreak of foodborne illness. Which epidemiological
measure identifies the number of new cases of a disease during a specific timeframe?
A. Incidence rate
B. Prevalence rate
C. Case fatality rate
D. Attack rate
Correct Answer: A
,Explanation: The incidence rate measures the frequency of new cases developing in a
population at risk during a specific period. It is essential for understanding the spread and
development of acute conditions or outbreaks. In contrast, prevalence measures all existing
cases (new and old) at a specific point in time.
4. Which statement best describes the ‘Upstream’ approach in population health nursing?
A. Focusing on treating individual symptoms as they arise in the clinical setting.
B. Prioritizing emergency response and disaster recovery efforts.
C. Addressing the social and environmental factors that contribute to poor health
outcomes.
D. Concentrating on rehabilitative services for patients with chronic disabilities.
Correct Answer: C
Explanation: Upstream thinking shifts the focus from individual treatment to the
socioeconomic and environmental origins of health problems. It involves identifying why
people are getting sick rather than just treating them after they become ill. This proactive
approach is fundamental to public health policy and systemic change.
5. A nurse is applying the Epidemiological Triad to understand the transmission of influenza.
Which factor represents the ‘Host’ in this model?
A. An unvaccinated elderly resident.
B. Cold, damp winter weather.
C. The influenza virus itself.
, D. Crowded living conditions in a nursing home.
Correct Answer: A
Explanation: The Epidemiological Triad consists of the agent, the host, and the
environment. The host is the human or animal that can be affected by the agent, influenced
by factors like age, immunity, and genetics. The virus is the agent, while weather and
crowding are environmental factors.
6. A community health nurse is focusing on ‘Healthy People 2030’ objectives. What is the
primary overarching goal of this national initiative?
A. To eliminate all infectious diseases by the end of the decade.
B. To attain healthy, thriving lives and well-being free of preventable disease and injury.
C. To provide universal health insurance coverage for all citizens.
D. To shift all healthcare delivery from hospitals to community-based clinics.
Correct Answer: B
Explanation: Healthy People 2030 aims to improve the health and well-being of the
population through data-driven objectives. The initiative focuses on health equity, social
determinants of health, and health literacy. By setting national goals, it provides a
framework for public health activities at all levels of government.
7. The nurse is reviewing the concept of Social Determinants of Health (SDOH). Which of the
following are categorized as SDOH? (Select all that apply)
A. Economic stability
