1. Q: What is the primary focus of community health nursing? ANSWER
Community health nursing focuses on promoting and preserving the health of
populations and communities through prevention, health promotion, and
population-level interventions rather than individual care alone.
2. Q: What are the three levels of prevention in community health?
ANSWER Primary prevention (preventing disease before it occurs), secondary
prevention (early detection and treatment), and tertiary prevention (reducing
complications and disability from existing disease).
3. Q: What is an example of primary prevention? ANSWER
Immunizations, health education programs, proper nutrition counseling,
exercise programs, and safety education are all examples of primary prevention.
4. Q: What defines a community in nursing practice? ANSWER A
community is a group of people who share common characteristics, interests, or
geographic location and interact with each other within a social system.
5. Q: What is the difference between community health nursing and public
health nursing? ANSWER While often used interchangeably, public health
nursing typically refers to government-employed nurses focusing on population
health, while community health nursing is broader and includes various settings
serving communities.
6. Q: What is population-focused care? ANSWER Population-focused care
addresses the health needs of entire groups or populations rather than
individuals, using epidemiological data to identify health trends and implement
interventions.
7. Q: What are social determinants of health? ANSWER Social
determinants are conditions in environments where people live, work, and play
that affect health outcomes, including education, economic stability, healthcare
access, neighborhood environment, and social context.
8. Q: What is health equity? ANSWER Health equity means everyone has a
fair and just opportunity to achieve their highest level of health, requiring
,removal of obstacles like poverty, discrimination, and lack of access to
resources.
9. Q: What is the nurse's role in case management? ANSWER The nurse
coordinates care, links clients with resources, monitors progress, advocates for
clients, and ensures cost-effective quality care delivery.
10. Q: What is community assessment? ANSWER A systematic process of
collecting, analyzing, and using data to understand a community's health status,
needs, resources, and priorities to plan appropriate interventions.
11. Q: What are the components of the epidemiological triangle? ANSWER
Agent (causative factor), host (susceptible person), and environment (external
factors that influence disease transmission).
12. Q: What is incidence? ANSWER Incidence is the number of new cases of
a disease or condition in a population during a specific time period.
13. Q: What is prevalence? ANSWER Prevalence is the total number of
existing cases of a disease or condition in a population at a given point in time
or during a specific period.
14. Q: What is herd immunity? ANSWER Herd immunity occurs when a
large portion of a population becomes immune to a disease, providing indirect
protection to those who are not immune.
15. Q: What is the purpose of Healthy People 2030? ANSWER Healthy
People 2030 provides science-based national objectives with 10-year targets to
improve health and well-being for all Americans.
16. Q: What is a windshield survey? ANSWER A windshield survey is a
method of community assessment where the nurse drives or walks through a
community to observe its characteristics, resources, and potential health
concerns.
17. Q: What is cultural competence in nursing? ANSWER Cultural
competence is the ability to understand, appreciate, and interact effectively with
people from different cultures, incorporating their beliefs and practices into
care.
18. Q: What is health literacy? ANSWER Health literacy is the ability to
obtain, process, and understand basic health information needed to make
appropriate health decisions.
,19. Q: What is the role of a parish nurse? ANSWER Parish nurses provide
health promotion, disease prevention, health counseling, and referrals within
faith communities, integrating faith and health.
20. Q: What is environmental health? ANSWER Environmental health
addresses physical, chemical, and biological factors external to a person that can
affect health, including air quality, water safety, and toxic exposures.
21. Q: What is epidemiology? ANSWER Epidemiology is the study of
distribution and determinants of health-related states in populations and the
application of this study to control health problems.
22. Q: What is a sentinel event? ANSWER A sentinel event is an unexpected
occurrence involving death or serious injury, signaling the need for immediate
investigation and response.
23. Q: What is the purpose of immunization registries? ANSWER
Immunization registries track vaccination records to ensure complete
immunization coverage, identify under-immunized populations, and prevent
disease outbreaks.
24. Q: What is screening in community health? ANSWER Screening is the
systematic application of tests to identify individuals at risk for or in early
stages of disease when intervention is most effective.
25. Q: What is the difference between mortality and morbidity? ANSWER
Mortality refers to death rates in a population, while morbidity refers to disease
or illness rates in a population.
26. Q: What is the nurse's role in disaster preparedness? ANSWER Nurses
plan for disasters, educate communities, participate in drills, provide emergency
care, coordinate resources, and assist in recovery efforts.
27. Q: What is advocacy in community health nursing? ANSWER
Advocacy involves actively supporting and promoting the rights, needs, and
interests of individuals, families, and communities to improve health outcomes.
28. Q: What are upstream interventions? ANSWER Upstream interventions
address root causes of health problems at the system or policy level, such as
changing laws or social conditions, rather than treating symptoms.
29. Q: What is a health disparity? ANSWER Health disparities are
preventable differences in disease burden, injury, violence, or opportunities to
achieve optimal health experienced by socially disadvantaged populations.
, 30. Q: What is the community health nurse's role in health promotion?
ANSWER The nurse educates communities, develops programs, facilitates
behavior change, creates supportive environments, and advocates for policies
that promote health.
Section 2: Epidemiology and Disease Prevention (Questions 31-60)
31. Q: What is an endemic disease? ANSWER An endemic disease is
constantly present in a specific geographic area or population at expected levels.
32. Q: What is an epidemic? ANSWER An epidemic is an increase in disease
cases beyond what is normally expected in a population or area.
33. Q: What is a pandemic? ANSWER A pandemic is an epidemic that has
spread across multiple countries or continents, affecting a large number of
people.
34. Q: What is the attack rate? ANSWER Attack rate is the proportion of
people who become ill after exposure to a disease agent, calculated as (number
of new cases/population at risk) × 100.
35. Q: What is the purpose of contact tracing? ANSWER Contact tracing
identifies and monitors people who have been exposed to an infectious disease
to prevent further transmission.
36. Q: What is the chain of infection? ANSWER The chain of infection
includes infectious agent, reservoir, portal of exit, mode of transmission, portal
of entry, and susceptible host.
37. Q: What is an example of secondary prevention? ANSWER
Mammography screening, blood pressure checks, cholesterol screenings, and
tuberculosis skin testing are examples of secondary prevention.
38. Q: What is an example of tertiary prevention? ANSWER Cardiac
rehabilitation after heart attack, diabetes management education, physical
therapy after stroke, and support groups for chronic conditions are tertiary
prevention examples.
