[SECTION 1: Community Health Concepts & Core Functions — Questions 1-8]
Q1: A Community Health Worker (CHW) is conducting a home visit to assess the immediate
environment of a client with asthma. The CHW notices mold in the bathroom and excessive dust
in the bedroom. Which of the following core functions of community health is being primarily
demonstrated?
A. Epidemiological surveillance
B. Environmental health assessment
C. Policy development
D. Infectious disease control
Correct Answer: B
Rationale: Environmental health assessment involves identifying and evaluating environmental
factors that affect human health, such as mold and dust which are triggers for asthma. This aligns
with the CHW role of connecting environmental conditions to health outcomes. Epidemiological
surveillance (A) tracks disease patterns, not specific home hazards. Policy development (C)
involves creating rules or laws, which is not the immediate action here. Infectious disease control
(D) focuses on preventing pathogen transmission, whereas asthma is a chronic condition
exacerbated by environmental allergens.
Q2: In the context of public health, what distinguishes primary prevention from secondary
prevention?
A. Primary prevention focuses on rehabilitation, while secondary prevention focuses on cure.
B. Primary prevention targets asymptomatic individuals to prevent disease onset, while
secondary prevention targets early disease detection.
C. Primary prevention is implemented only in hospital settings, while secondary prevention is
community-based.

D. Primary prevention treats existing complications, while secondary prevention prevents risk
factors.
Correct Answer: B
Rationale: Primary prevention aims to prevent disease before it occurs (e.g., vaccinations),
targeting healthy, asymptomatic individuals. Secondary prevention aims to reduce the impact of
a disease that has already occurred through early detection and intervention (e.g., screening for
hypertension). Options A and D incorrectly define rehabilitation and tertiary care. Option C is
incorrect because primary prevention (like health education) often occurs in community settings,
not just hospitals.
Q3: A CHW is tasked with organizing a flu shot clinic in a rural area with limited transportation.
Which of the following strategies best exemplifies the core function of "Assurance"?
A. Surveying the community to determine flu vaccination rates.
B. Educating residents about the importance of hand washing.
C. Partnering with a mobile unit to provide vaccines at a central community location.
D. Advocating for state laws requiring flu shots for school entry.
Correct Answer: C
Rationale: Assurance refers to the public health responsibility to ensure that necessary services
are available to the population. Partnering with a mobile unit to provide accessible vaccines
guarantees that the service reaches the community despite transportation barriers. Surveying
rates (A) is assessment. Educating (B) is health promotion, often under policy development or
health education functions. Advocating for laws (D) is policy development, not assurance of
service delivery.
Q4: Which of the following best describes the "Population Health" approach utilized by
Community Health Workers?
A. Focusing exclusively on the individual treatment of acute illnesses in a clinical setting.
B. Addressing the health outcomes of a group of individuals, including the distribution of
outcomes within the group.
C. Conducting biological research on cellular mechanisms of disease.

D. Managing the financial billing and coding for hospital services.
Correct Answer: B
Rationale: Population health focuses on health outcomes of a defined group of people and the
distribution of those outcomes, looking at broad determinants rather than just individual medical
care. Option A describes clinical medicine, not population health. Option C describes basic
science research. Option D describes administrative health functions unrelated to the CHW
scope.
Q5: A CHW is utilizing the "Ecological Model of Health" to plan an intervention. Which of the
following levels of influence is being addressed if the CHW advocates for safer street lighting to
improve evening physical activity?
A. Intrapersonal level
B. Interpersonal level
C. Organizational level
D. Community/Environmental level
Correct Answer: D
Rationale: The Ecological Model includes multiple levels; the community or environmental level
refers to the physical, social, and political environment, such as street lighting. Intrapersonal (A)
refers to individual knowledge and attitudes. Interpersonal (B) refers to relationships with family
and friends. Organizational (C) refers to institutions like schools or workplaces, whereas street
lighting is a broader community infrastructure issue.
Q6: When evaluating the effectiveness of a new diabetes walking program, the CHW notes that
while attendance is high, participants' A1C levels have not changed after three months. Which
evaluation measure is the CHW assessing?
A. Process evaluation
B. Impact evaluation
C. Outcome evaluation
D. Summative evaluation
