1. Epidemiology and Disease Control
2. Environmental Health Hazards
3. Health Policy and Systems
4. Social Determinants of Health
5. Community Health Intervention Planning
1. A community health official identifies a cluster of unexplained respiratory illnesses near an
industrial site. Which immediate epidemiological step is the most critical to determine the scope
of the potential outbreak?
A. Implementing a mandatory mask mandate for the affected neighborhood.
B. Conducting a case-control study to compare exposure histories of affected individuals
against a healthy control group.
C. Suspending operations at the industrial site immediately to prevent further exposure.
D. Issuing a public alert to all residents in the municipality to seek medical screening.
CORRECT ANSWER : B
Rationale: Conducting a case-control study is the most effective initial epidemiological step to
identify specific risk factors or exposures linked to the illness cluster. Option A is premature,
option C lacks evidence to justify legal action, and option D may cause unnecessary public panic
without confirmed etiology.
,2. When evaluating the impact of social determinants of health (SDOH) on a specific population,
which factor is most frequently cited as the strongest predictor of long-term health outcomes?
A. Availability of local primary care facilities.
B. Proximity to emergency surgical services.
C. Socioeconomic status, specifically income inequality and educational attainment.
D. Individual genetic predispositions to chronic conditions.
CORRECT ANSWER : C
Rationale: Extensive public health research consistently identifies socioeconomic status as the
primary driver of health disparities, influencing environment, nutrition, and stress. Options A
and B are important but secondary to the broader structural impacts of socioeconomic status,
and D is a biological factor rather than a social determinant.
3. A local health department is designing a program to reduce teenage tobacco use. Which
intervention strategy utilizes the "Health Belief Model" most effectively?
A. Increasing the excise tax on tobacco products at the state level.
B. Highlighting the perceived susceptibility to long-term lung damage and the benefits of
cessation through targeted peer-led workshops.
C. Banning the sale of flavored tobacco products within city limits.
D. Increasing the legal age for tobacco purchase to 21.
CORRECT ANSWER : B
Rationale: The Health Belief Model focuses on an individual's perception of susceptibility and
the benefits of changing behavior, which peer-led education addresses. Options A, C, and D are
policy-level structural interventions, not behavioral model applications.
4. Which regulatory framework is essential for maintaining the safety of the public water supply in
the United States?
A. OSHA Hazardous Materials Standards.
B. The Safe Drinking Water Act (SDWA).
C. The Clean Air Act.
D. The Resource Conservation and Recovery Act.
, CORRECT ANSWER : B
Rationale: The Safe Drinking Water Act (SDWA) is the federal law that protects public drinking
water supplies throughout the nation. Option A pertains to workplace safety, C to air quality,
and D to hazardous waste management.
5. A public health analyst is interpreting morbidity data for a population of 50,000. If 250 new
cases of diabetes are reported in one year, what is the annual incidence rate per 1,000
population?
A. 0.5 per 1,000.
B. 5 per 1,000.
C. 10 per 1,000.
D. 25 per 1,000.
CORRECT ANSWER : B
Rationale: Incidence rate is calculated by dividing new cases (250) by the population (50,000),
which equals 0.005, then multiplying by 1,000 to get 5 per 1,000. Option A, C, and D are
incorrect calculations based on the standard epidemiological formula.
6. Which activity is considered a secondary prevention strategy in public health?
A. Administering childhood immunizations to prevent polio.
B. Providing nutritional counseling to a community with high rates of obesity.
C. Screening asymptomatic individuals for hypertension during a community health fair.
D. Coordinating physical therapy for patients recovering from a stroke.
CORRECT ANSWER : C
Rationale: Secondary prevention involves the early detection of disease in asymptomatic
individuals to allow for prompt intervention. Option A is primary prevention, option B is primary
prevention, and option D is tertiary prevention.
7. What is the primary purpose of a "Health Impact Assessment" (HIA) in policy development?
A. To evaluate the cost-effectiveness of a new medical device.
B. To provide a structured process for assessing the potential health effects of a proposed
project, plan, or policy.
