1. What is community-based nursing?
Correct Answer: Nursing care directed toward a specific group or population within the community
that may be provided for individuals and groups; setting-specific; emphasis on acute and chronic care.
1. Community-based nursing focuses on individuals and families where they live, work, and go to
school.
2. It is setting-specific (e.g., home health, school nursing, occupational health).
3. Emphasis is on acute and chronic illness management rather than population-level prevention.
2. What is primary prevention?
Correct Answer: Preventing a problem before it occurs by altering susceptibility or reducing exposure
for susceptible individuals.
1. Primary prevention occurs before disease onset and targets healthy individuals.
2. Includes health promotion (nutrition, exercise) and specific protection (immunizations).
3. Most cost-effective level of prevention.
3. What is general health promotion in primary prevention?
Correct Answer: Enhances resiliency and protective factors and targets essentially well populations.
1. Health promotion activities aim to improve overall health and well-being.
2. Examples include good nutrition, physical activity, stress management.
3. Directed at populations without specific disease risk factors.
4. What are examples of general health promotion in primary prevention?
Correct Answer: Promotion of good nutrition; encouraging regular exercise.
1. Healthy People 2030 emphasizes nutrition and physical activity goals.
2. These behaviors reduce risk for chronic diseases (obesity, diabetes, heart disease).
3. Community-wide campaigns (5-2-1-0, walking trails) are examples.
, 5. What are specific protection efforts in primary prevention?
Correct Answer: Reduce or eliminate risk factors.
1. Specific protection targets identifiable risk factors for disease.
2. Examples include immunizations, water purification, sanitation.
3. May also include chemoprophylaxis (malaria, TB prevention).
6. What are examples of specific protection efforts in primary prevention?
Correct Answer: Immunization and water purification.
1. Immunizations prevent vaccine-preventable diseases (polio, measles, tetanus).
2. Water purification prevents waterborne diseases (cholera, typhoid).
3. Both are classic public health interventions.
7. What is secondary prevention?
Correct Answer: Early detection and prompt intervention during the period of early disease
pathogenesis.
1. Secondary prevention identifies disease at earliest stage before symptoms appear.
2. Goal is to halt disease progression and reduce morbidity/mortality.
3. Examples include screening tests (mammography, BP screening).
8. What are examples of secondary prevention?
Correct Answer: Mammography, blood pressure screening, scoliosis screening.
1. Mammography detects breast cancer early to improve treatment outcomes.
2. Blood pressure screening identifies hypertension for early management.
3. Scoliosis screening in schools identifies spinal curvature for early intervention.
9. What is tertiary prevention?
Correct Answer: Keeps health problems from getting worse, reduces effects of disease and injury, and
restores individuals to optimal level of functioning.
1. Tertiary prevention focuses on rehabilitation and preventing complications.
2. Occurs after disease is established to improve quality of life.
3. Examples include patient education (insulin injections), stroke rehabilitation.
10. What is an example of tertiary prevention?
Correct Answer: Teaching a patient how to perform insulin injections.
1. Diabetes self-management prevents complications (retinopathy, neuropathy, kidney disease).
2. Tertiary prevention maximizes function despite chronic illness.
3. Includes medication management, diet teaching, and monitoring.
