Questions And Answers With Rationales 2026
1. Which of the following best describes population health?
A. Focuses only on individual patient care
B. Focuses on health outcomes of groups of individuals, including
distribution within the group
C. Only addresses infectious diseases
D. Measures health only at a national level
Rationale: Population health emphasizes health outcomes for groups,
not just individuals, and considers disparities within populations.
2. Social determinants of health include all of the following EXCEPT:
A. Education
B. Economic stability
C. Genetic predisposition
D. Neighborhood environment
Rationale: Social determinants are external factors influencing health,
whereas genetics is an intrinsic factor.
3. What is the primary goal of public health surveillance?
A. Treat individual patients
B. Monitor and prevent disease in populations
C. Provide health insurance
D. Conduct clinical trials
Rationale: Public health surveillance aims to identify trends, detect
outbreaks, and guide interventions at the population level.
4. Which model focuses on the interaction between host, agent,
and environment in disease causation?
A. Health Belief Model
B. PRECEDE-PROCEED Model
C. Epidemiologic Triad
D. Social Cognitive Theory
,Rationale: The epidemiologic triad explains disease through host,
agent, and environmental factors.
5. Health disparities refer to:
A. Differences in health outcomes linked to social, economic, or
environmental disadvantage
B. Minor variations in individual health
C. Universal health improvements
D. Genetic disorders only
Rationale: Health disparities are systematic, avoidable, and linked to
inequity.
6. Which of the following is an example of primary prevention?
A. Chemotherapy for cancer
B. Vaccination against influenza
C. Blood pressure medication for hypertension
D. Rehabilitation after stroke
Rationale: Primary prevention aims to prevent disease before it
occurs.
7. The leading cause of death worldwide is:

Rationale: Globally, cardiovascular diseases remain the leading cause
of mortality.
8. Which level of prevention aims to reduce complications after a

, Rationale: Tertiary prevention focuses on reducing the impact of an
ongoing illness or injury.
9. Screening for hypertension in asymptomatic adults is an example
of:
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Quaternary prevention
Rationale: Secondary prevention detects disease early to prevent
progression.
10. Health promotion primarily focuses on:
A. Disease treatment
B. Encouraging healthy behaviors to improve well-being
C. Hospital care
D. Pharmacological interventions only
Rationale: Health promotion empowers individuals and communities
to maintain or improve health.
11. Which factor is most strongly associated with life expectancy
differences among populations?
A. Genetic mutations
B. Socioeconomic status
C. Blood type
D. Diet alone
Rationale: Socioeconomic status influences access to healthcare,
nutrition, and safe environments, affecting longevity.
12. The concept of “herd immunity” is best applied to:
A. Nutrition programs
B. Physical activity promotion
C. Vaccination programs
D. Mental health interventions
