Q1: Which of the following best describes the primary goal of public health?
A. To provide acute medical care to individuals suffering from infectious diseases.
B. To ensure the availability of specialized surgical services in rural hospitals.
C. To protect and improve the health of communities and populations through education,
promotion of healthy lifestyles, and research for disease and injury prevention.
D. To focus exclusively on the environmental cleanliness of urban industrial zones.
Correct Answer: C
Rationale: Correct because public health focuses on population-level health outcomes and
prevention strategies rather than individual medical treatment. This matches the core definition
of public health practice.
Q2: A community health nurse is conducting a windshield survey of a neighborhood. Which of
the following observations would most accurately indicate a lack of social capital?
A. The presence of multiple abandoned buildings and vacant lots.
B. A lack of grocery stores offering fresh produce.
C. Absence of safe recreational spaces like parks or playgrounds.
D. Visible signs of neighborhood decay such as graffiti and broken windows, but also an absence
of community gatherings or interactions among residents.
Correct Answer: D

Q3: In epidemiology, the "mode of transmission" refers to:
A. The specific biological agent causing the disease.
B. The mechanism by which an infectious agent is transferred from a reservoir to a susceptible
host.
C. The geographical area where the disease originated.
D. The severity of the illness resulting from the infection.
Correct Answer: B
Rationale: Correct because mode of transmission is defined as the process by which a pathogen
moves from a source or reservoir to a new host. This matches standard epidemiological
terminology.
Q4: When planning a health promotion program, which step involves identifying the target
population and assessing their specific health needs?
A. Implementation.
B. Evaluation.
C. Needs Assessment.
D. Policy Development.
Correct Answer: C
Rationale: Correct because the needs assessment is the foundational step in program planning
where data is gathered to understand the health status, behaviors, and needs of the priority
population. This ensures the program is relevant.

A. Vaccination against influenza.
B. Regular mammography screening for breast cancer.
C. Physical therapy following a stroke.
D. Education on the dangers of smoking.

Q6: Use the following data to answer the question:
In a city of 100,000 people, there were 500 new cases of diabetes diagnosed in 2025. The total
number of existing cases of diabetes at the end of 2025 was 10,000. What is the incidence rate
of diabetes in 2025?
A. 10 per 1,000.
B. 5 per 1,000.
C. 50 per 1,000.
D. 100 per 1,000.
Correct Answer: B
Rationale: Correct because incidence is calculated as the number of new cases divided by the
population at risk during a specific time period. (,000) = 0.005, which is 5 per 1,000.
Q7: Which level of the Socio-Ecological Model focuses on the influence of laws, policies, and
regulations on health behavior?
A. Individual Level.
B. Interpersonal Level.
C. Community Level.
D. Policy Level.
Correct Answer: D
Rationale: Correct because the Policy Level involves broad systemic factors, including local,

and play.
