1. A county health department wants to reduce childhood asthma exacerbations in
a neighborhood with high traffic density. After reviewing community data,
officials propose regulations that limit diesel truck traffic near elementary schools
and require anti-idling enforcement. Which level of the Socio-Ecological Model is
the primary focus of this intervention?
A. Intrapersonal
B. Interpersonal
C. Community
D. Public policy
Answer: D
Rationale: Public policy interventions change laws, regulations, or governmental
requirements that affect population health. Restrictions on diesel traffic and anti-
idling regulations are policy-level actions rather than interventions directed
primarily at individual behavior, relationships, or neighborhood norms.
,2. A public health nurse begins planning a diabetes prevention program for a rural
community. Before reviewing disease rates, the nurse conducts focus groups to
learn how residents describe their quality of life, major concerns, and priorities for
the community. Which phase of the PRECEDE-PROCEED model is being
addressed?
A. Epidemiological assessment
B. Social assessment
C. Administrative and policy assessment
D. Implementation
Answer: B
Rationale: The social assessment examines how community members perceive
their quality of life and identifies social priorities and concerns. Epidemiological
assessment occurs after this step and focuses on health-related data such as
morbidity and mortality.
3. A city health department examines hospitalization rates, mortality statistics, and
the prevalence of hypertension across several neighborhoods before deciding
which health problem requires the greatest attention. Which component of the
PRECEDE-PROCEED model does this activity represent?
A. Social assessment
B. Epidemiological assessment
C. Behavioral and environmental assessment
D. Process evaluation
Answer: B
Rationale: Epidemiological assessment uses quantitative health information,
including morbidity, mortality, prevalence, and related disease patterns, to identify
priority health problems and their magnitude within a population.
,4. At the beginning of a calendar year, a community has 10,000 residents who are
free of a particular infectious disease. During the year, 125 residents develop the
disease. Which incidence measure is most appropriate?
A. 1.25 cases per 100 residents
B. 12.5 cases per 1,000 persons at risk
C. 125 cases per 1,000 persons at risk
D. 1,250 cases per 100,000 persons at risk
Answer: B
Rationale: Incidence measures new cases occurring in a population at risk during
a specified period. Here, 125 ÷ 10,000 × 1,000 = 12.5 new cases per 1,000
persons at risk.
5. A community clinic reports that 840 adults currently live with diagnosed
hypertension. The total adult population served by the clinic is 12,000. The health
department wants to estimate the overall burden of hypertension in this population
at one point in time. Which measure should be calculated?
A. Incidence
B. Prevalence
C. Attack rate
D. Case-fatality rate
Answer: B
Rationale: Prevalence describes all existing cases of a condition within a
population at a specified time or over a specified period. Because the health
department is interested in the existing burden of hypertension, prevalence is the
appropriate measure.
, 6. A nurse provides influenza vaccination clinics for adults before the start of flu
season. The individuals receiving the vaccine do not currently have influenza.
Which level of prevention does this intervention represent?
A. Primary
B. Secondary
C. Tertiary
D. Quaternary
Answer: A
Rationale: Primary prevention occurs before disease develops and is intended to
prevent its occurrence. Immunization is a classic example because it reduces the
likelihood of disease developing in susceptible individuals.
7. A community health center offers blood pressure screening at a neighborhood
health fair. Several participants with previously unrecognized hypertension are
referred for diagnostic follow-up. Which level of prevention is demonstrated?
A. Primary
B. Secondary
C. Tertiary
D. Population rehabilitation
Answer: B
Rationale: Secondary prevention focuses on early detection of disease and prompt
intervention. Blood pressure screening identifies disease that may be present but
not yet diagnosed, allowing treatment to begin before complications develop.
