1. What is the primary focus of community/public health nursing?
A. Treating acute illness in hospitalized patients
B. Improving the health of populations through prevention and health promotion
C. Performing surgical procedures
D. Providing intensive care to critically ill patients
Rationale: Community health nursing emphasizes population health, prevention,
health promotion, and reducing health risks.
2. Which activity is an example of primary prevention?
A. Screening adults for colorectal cancer
B. Administering childhood immunizations
C. Providing rehabilitation after a stroke
D. Monitoring a patient with established diabetes
Rationale: Primary prevention prevents disease before it occurs.
3. Which intervention represents secondary prevention?
A. Smoking-prevention education
B. Mammography screening
C. Physical rehabilitation after hip surgery
D. Hospice care
Rationale: Secondary prevention identifies disease early through screening and
early detection.
4. Which intervention is considered tertiary prevention?
A. Childhood vaccination
B. Blood pressure screening
C. Cardiac rehabilitation after myocardial infarction
D. Teaching hand hygiene
Rationale: Tertiary prevention limits complications and improves function after
disease has occurred.
5. A nurse is beginning a community assessment. Which action should occur first?
A. Implement an intervention
B. Identify community health needs and available resources
C. Evaluate outcomes
D. Write discharge instructions
Rationale: Assessment precedes planning and intervention.
6. Which factor is a social determinant of health?
A. Blood type
B. Housing stability
,C. Heart rhythm
D. Body temperature
Rationale: Housing, income, education, transportation, and social support can
significantly influence health outcomes.
7. A nurse notices that a neighborhood has no grocery store selling fresh produce.
Which health issue may result?
A. Improved nutritional access
B. Food insecurity
C. Increased healthcare literacy
D. Reduced environmental exposure
Rationale: Limited access to affordable nutritious food is an important social
determinant of health.
8. Which population is generally considered vulnerable?
A. Individuals with abundant healthcare access
B. Individuals experiencing homelessness
C. Individuals with comprehensive insurance
D. Individuals living in areas with multiple healthcare facilities
Rationale: Homelessness can create significant barriers to healthcare, housing,
nutrition, and preventive services.
9. What is the primary purpose of epidemiology?
A. Provide individual psychotherapy
B. Study the distribution and determinants of health-related events in populations
C. Replace clinical nursing assessment
D. Perform surgical interventions
populations.
Rationale: Epidemiology examines patterns, causes, and effects of health conditions
within populations.
10. Which term describes the number of existing cases of a disease in a population
at a specific time?
A. Incidence
B. Prevalence
C. Mortality
D. Attack rate
Rationale: Prevalence measures existing cases, whereas incidence measures new
cases.
11. Which measure describes newly occurring cases of a disease during a specified
period?
A. Incidence
B. Prevalence
C. Mortality
D. Disability rate
Rationale: Incidence measures new cases occurring within a defined population
during a specified period.
, 12. A community experiences an unusually high number of influenza cases during
one month. This situation is best described as a:
A. Pandemic
B. Sporadic event
C. Outbreak
D. Chronic condition
Rationale: An outbreak is an occurrence of disease cases above what is normally
expected in a particular setting or population.
13. Which situation best describes a pandemic?
A. Disease limited to one household
B. Disease occurring worldwide or across multiple countries or continents
C. A single isolated case
D. Disease limited to one hospital unit
Rationale: A pandemic involves widespread transmission across large geographic
areas.
14. Which action is most appropriate when a communicable disease outbreak is
suspected?
A. Ignore isolated cases
B. Begin appropriate surveillance and report according to public health
requirements
C. Immediately close every healthcare facility
D. Stop collecting epidemiologic information
Rationale: Surveillance and timely reporting help identify and control outbreaks.
15. Which factor is part of the epidemiologic triad?
A. Insurance
B. Agent
C. Income
D. Education
Rationale: The classic epidemiologic triad consists of agent, host, and environment.
16. In the epidemiologic triad, the person who is susceptible to a disease is the:
A. Agent
B. Host
C. Vector
D. Reservoir
Rationale: The host is the individual or organism capable of harboring and being
affected by the agent.
17. Which is an example of an environmental factor in the epidemiologic triad?
A. Genetic susceptibility
B. Pathogenic microorganism
C. Poor sanitation
D. Immune response
Rationale: Environmental conditions can facilitate or inhibit disease transmission.
