DETAILED ANSWERS - LATEST VERSION - TOP RATED 2026/2027
1. What is community health nursing?
Community health nursing is a synthesis of nursing practice and public health
principles applied to promote and preserve the health of populations. It focuses
on the health of the entire community rather than individuals alone.
2. What is the primary goal of community health nursing?
The primary goal is to preserve and improve the health of entire
populations/communities by providing preventive, promotive, and restorative
care.
3. How does community health nursing differ from hospital nursing?
Community health nursing focuses on population-based care, disease
prevention, and health promotion in community settings, while hospital nursing
focuses primarily on treating illness in acutely ill individuals.
4. What are the core functions of public health?
The three core functions are: Assessment (monitoring health status), Policy
Development (informing and educating the public), and Assurance (ensuring
services are provided).
5. Define the term 'aggregate' in community health nursing.
An aggregate is a group of individuals who share one or more personal or
environmental characteristics, such as age group, gender, geographic location,
or health condition.
6. What is epidemiology?
Epidemiology is the study of the distribution and determinants of health-related
states or events in specified populations, and the application of this study to
control health problems.
7. What is the epidemiological triad?
, The epidemiological triad consists of three components: Host (the person at
risk), Agent (the cause of disease), and Environment (external factors
influencing exposure).
8. Define incidence rate.
Incidence rate is the number of new cases of a disease or condition occurring in
a population during a specific time period, divided by the total population at
risk during that period.
9. Define prevalence rate.
Prevalence rate is the total number of existing cases (new and old) of a disease
or condition in a population at a given point in time, divided by the total
population.
10. What is morbidity?
Morbidity refers to the rate of disease or illness in a population, indicating how
common a disease is in a specific location or group.
11. What is mortality?
Mortality refers to the death rate in a population, often used to compare the
severity of diseases or measure the impact of health interventions.
12. What is primary prevention?
Primary prevention includes actions taken before a disease occurs to prevent its
onset, such as immunizations, health education, and lifestyle modification
programs.
13. What is secondary prevention?
Secondary prevention involves early detection and treatment of disease to
minimize severity and prevent complications, such as screening programs (e.g.,
mammograms, Pap smears).
14. What is tertiary prevention?
Tertiary prevention focuses on reducing the impact of established disease
through rehabilitation and management to prevent further deterioration and
improve quality of life.
15. Who is considered the founder of modern epidemiology?
John Snow is considered the founder of modern epidemiology, known for his
investigation of the 1854 Broad Street cholera outbreak in London.
16. What is a health disparity?
, A health disparity is a preventable difference in the burden of disease, injury,
violence, or opportunities to achieve optimal health experienced by socially
disadvantaged populations.
17. What are the social determinants of health?
Social determinants of health are conditions in the environments where people
are born, live, learn, work, play, worship, and age that affect health outcomes,
such as income, education, housing, and access to healthcare.
18. What is Healthy People 2030?
Healthy People 2030 is a national initiative that sets data-driven 10-year
national objectives to improve the health and well-being of all Americans,
released by the U.S. Department of Health and Human Services.
19. Define 'community' in the context of community health nursing.
A community is a group of people who share something in common, such as
geography, culture, values, interests, or health concerns, and who interact with
one another.
20. What is a windshield survey?
A windshield survey is a method of community assessment conducted from a
vehicle, observing the community's physical environment, social conditions,
resources, and potential health risks.
21. What are Levels of Prevention according to Leavell and Clark?
Levels of Prevention include: Primary (health promotion and specific
protection), Secondary (early diagnosis and prompt treatment), and Tertiary
(disability limitation and rehabilitation).
22. What is the natural history of disease?
The natural history of disease refers to the progression of a disease process in
an individual over time, from susceptibility through sub-clinical and clinical
stages to resolution (recovery, disability, or death).
23. What does the acronym PHN stand for?
PHN stands for Public Health Nurse, a registered nurse who specializes in
community/public health practice focused on population-level health promotion
and disease prevention.
24. What is health promotion?
Health promotion is the process of enabling people to increase control over
their health and its determinants to improve their health, encompassing
education, environmental supports, and policy changes.
, 25. What is a community health assessment?
A community health assessment is a systematic examination of the health status
indicators for a given population, used to identify key problems and assets in a
community, to provide a basis for planning health services.
Unit 2: Vulnerable Populations
26. Who are considered vulnerable populations in community health?
Vulnerable populations are groups at greater risk for poor health outcomes due
to limited resources, marginalization, or increased exposure to risk, including
the homeless, elderly, children, migrant workers, and those with mental illness.
27. What factors contribute to vulnerability in populations?
Factors include poverty, lack of access to healthcare, social isolation,
discrimination, lack of education, language barriers, and environmental hazards.
28. What is the cycle of poverty?
The cycle of poverty is a phenomenon where poverty and its associated
conditions—poor health, limited education, and lack of resources—perpetuate
themselves across generations, making it difficult for individuals to escape.
29. How does poverty affect health?
Poverty leads to inadequate nutrition, poor housing, limited access to
healthcare, higher exposure to environmental hazards, and increased
psychological stress, all of which negatively impact health.
30. What is the role of the community health nurse in caring for the homeless?
The community health nurse provides outreach services, screenings, health
education, referrals to shelters and social services, and advocates for affordable
housing and policy changes to address homelessness.
31. What are common health problems among the homeless population?
Common health problems include mental illness, substance abuse, tuberculosis,
HIV/AIDS, diabetes, hypertension, dental problems, skin conditions, and
trauma.
32. Who are migrant and seasonal farm workers?
Migrant workers move from place to place for employment, while seasonal
