- A Primary prevention
- B Secondary prevention
- C Tertiary prevention
- D Primordial prevention

- A Legislation-based prevention
- B Community-based education
- C Behavioral nudging
- D Surveillance-based enforcement

A hospital integrates mental health services into primary care clinic visits. This approach reduces fragmentation by using:
- A Horizontal integration
- B Vertical integration
- C Fee-for-service expansion
- D Global budgeting
Correct answer: Vertical integration
Vertical integration coordinates services across different levels of care (primary to specialty).
A clinic reviews data showing that low-income patients have higher rates of uncontrolled diabetes. Which population health concept applies?
- A Health inequity
- B Incidence bias
- C Random error
- D Lead-time bias
Correct answer: Health inequity
Health inequities are systematic disparities in health outcomes linked to social or economic disadvantage.
A public health team monitors weekly influenza activity to detect outbreaks. Which function is being performed?
- A Assessment
- B Policy development
- C Assurance
- D Resource allocation
Correct answer: Assessment
Assessment includes surveillance and analysis of population health data.
A program provides free insulin and diabetes education to patients with complications. This is an example of:
- A Primary prevention
- B Secondary prevention
- C Tertiary prevention
- D Quaternary prevention
Correct answer: Tertiary prevention
Tertiary prevention focuses on managing established disease to prevent disability and improve quality of life.
A research team finds that areas with more primary care physicians have better population health outcomes. This represents:
- A Health system capacity
- B Selection bias
- C Random variation
- D Incidence decline
Correct answer: Health system capacity
Greater primary care capacity improves access, prevention, and coordination of care.
A health department vaccinates an entire community during an outbreak. Which public health function does this represent?
- A Assessment
- B Policy development
- C Assurance
- D Quaternary prevention
Correct answer: Assurance
Assurance ensures delivery of essential health services to protect population health.
A patient delays care because they lack transportation to the clinic. This barrier reflects which determinant?
- A Biological factor
- B Behavioral factor
- C Structural determinant
- D Genetic determinant
Correct answer: Structural determinant
Structural determinants include transportation, housing, income, and availability of services.
A public health program provides breastfeeding education to new mothers. This intervention targets which level?
- A Individual level
- B Policy level
- C Environmental level
- D Healthcare system level

Education directed toward individuals modifies their knowledge and behaviors.
A country invests heavily in sanitation and clean water systems to reduce infectious diseases. What type of prevention is this?
- A Primary prevention
- B Secondary prevention
- C Tertiary prevention
- D Quaternary prevention
Correct answer: Primary prevention
Clean water and sanitation prevent disease onset by removing exposure to pathogens.
A community hospital and local health department collaborate to reduce opioid overdose deaths. This is an example of:
- A Population–clinic linkage
- B Vertical integration
- C Sentinel surveillance
- D Patient navigation
Correct answer: Population–clinic linkage
Population–clinic linkages strengthen coordination between healthcare and public health systems.
A homeless shelter provides influenza vaccines to residents. Which population health principle is being applied?
- A Targeting high-risk populations
- B Community-wide universal strategy
- C Tertiary disease management
- D Ecologic prevention
Correct answer: Targeting high-risk populations
Targeted interventions address higher-risk groups to reduce disparities and protect public health.
A government mandates calorie labels on restaurant menus to encourage healthier choices. This is an example of:
- A Nudging
- B Screening
- C Tertiary prevention
- D Risk stratification
Correct answer: Nudging
Nudging alters environments to promote healthier decisions without eliminating choices.
A patient’s lack of health insurance prevents them from receiving cancer treatment. This is an example of:
- A Health disparity
- B Random error
- C Recall bias
- D Personal preference
Correct answer: Health disparity
Health disparities arise from unequal access to care, insurance, and resources.
A program trains community health workers to assist with chronic disease management at home. This is an example of:
- A Evidence-based medicine
- B Task shifting
- C Health literacy enhancement
- D Vertical surveillance
Correct answer: Task shifting
Task shifting delegates specific care activities to trained non-physician workers to improve access.
A state tracks childhood lead levels across zip codes to identify high-risk communities. This is an example of:
- A Descriptive epidemiology
- B Analytic epidemiology
- C Tertiary prevention
- D Case–control study
Correct answer: Descriptive epidemiology
Descriptive epidemiology examines distribution of disease by person, place, and time.
A health system allocates additional funding to clinics serving older adults because this population is growing rapidly. Which concept does this reflect?
