A community health nurse is explaining the purpose of public health to a
group of nursing students. Which statement best describes public health?
Correct Answer:
The science and art of preventing disease, prolonging life, and promoting health through
organized community efforts
Expert Rationale:
Public health focuses on improving the health of populations through organized societal
efforts aimed at disease prevention, health promotion, and life prolongation. It addresses
environmental, social, and behavioral factors affecting community health outcomes rather
than focusing solely on individual patient care.
Why other options are incorrect:
• Providing acute care to hospitalized clients: this reflects tertiary care rather than public
health.
• Diagnosing illnesses in primary care clinics: this focuses on individual treatment rather
than population health.
• Managing rehabilitation after injury: this is a restorative healthcare service rather than a
public health function.

OBJ: Describe the purpose and focus of public health

A nurse is reviewing major public health achievements in the United States.
Which achievement significantly reduced infectious disease rates through
immunity development?
,Correct Answer:
Vaccination
Expert Rationale:
Vaccination is considered one of the greatest public health achievements because it
dramatically reduced morbidity and mortality from infectious diseases such as polio,
measles, and smallpox. Immunization programs create herd immunity, protecting both
vaccinated and vulnerable populations.
Why other options are incorrect:
• Motor vehicle safety: reduces injuries and fatalities from accidents rather than infectious
diseases.
• Family planning: focuses on reproductive health and pregnancy prevention.
• Fluoridation of drinking water: primarily improves dental health.

A nursing student asks who is considered the mother of public health nursing.
Which response by the instructor is correct?
Correct Answer:
Lillian Wald
Expert Rationale:
Lillian Wald is recognized as the founder of public health nursing due to her work with
underserved populations through the Henry Street Settlement. She emphasized community-
based nursing care, health education, and social reform to improve population health.
Why other options are incorrect:
• Florence Nightingale: known as the founder of modern nursing, not specifically public
health nursing.
• Clara Barton: founder of the American Red Cross.
• Dorothea Dix: advocate for mental health reform.

A community health nurse is comparing causes of death in the early 1900s to
current trends in the United States. Which statement is most accurate?
Correct Answer:
Communicable diseases were the leading causes of death in 1900, whereas chronic diseases
are the leading causes today
Expert Rationale:
In the early 1900s, infectious diseases such as tuberculosis and pneumonia were leading
causes of mortality due to limited sanitation and antibiotics. Advances in medicine and
public health shifted mortality patterns toward chronic diseases such as heart disease,
cancer, and diabetes.
Why other options are incorrect:
• Chronic diseases have always been the leading cause of death: this is inaccurate
historically.
• Injuries were the leading cause of death in both periods: not supported by epidemiologic
data.
• Maternal mortality remains the leading cause of death today: this is incorrect.
DIF: Analysis
REF: Epidemiology Trends
OBJ: Compare historical and current causes of mortality
TOP: Disease Patterns
A public health nurse is discussing why healthcare spending in the United
States remains extremely high. Which factor contributes most significantly?
Correct Answer:
The healthcare system focuses more on tertiary care than primary prevention
Expert Rationale:
The U.S. healthcare system spends heavily on advanced treatments, hospitalizations, and
management of chronic disease complications rather than investing sufficiently in
preventive services and health promotion. This emphasis on tertiary care contributes to
rising healthcare expenditures.
Why other options are incorrect:
• Excessive use of vaccinations: preventive care is generally cost-effective.
, • Overuse of public health screenings: screenings reduce long-term complications and costs.
• Limited access to specialty care: the U.S. actually has extensive specialty services.
DIF: Analysis
REF: Healthcare Economics
OBJ: Explain factors contributing to high healthcare spending

A nurse is planning a community health intervention for reducing hypertension in a
low-income urban population. Which intervention represents primary prevention?
A. Providing antihypertensive medications to diagnosed clients
B. Screening adults for elevated blood pressure at a clinic
C. Teaching low-sodium dietary choices at a community workshop
D. Managing complications of stroke in rehabilitation units
Correct Answer: C
Expert Rationale: Primary prevention focuses on preventing disease before it occurs by
reducing risk factors and promoting healthy behaviors. Teaching low-sodium dietary
choices helps individuals avoid developing hypertension by addressing modifiable
lifestyle risks such as diet and salt intake. Screening for elevated blood pressure is
secondary prevention because it identifies disease early, while antihypertensive
medications and stroke rehabilitation are tertiary prevention strategies aimed at managing
established disease and complications. Community health nursing emphasizes
population-level education and risk reduction to prevent chronic disease onset.
DIF: Application
REF: Levels of Prevention
OBJ: Differentiate primary, secondary, and tertiary prevention
TOP: Health Promotion
A nurse is conducting a home visit for a client with tuberculosis. Which action is the
priority for community safety?
A. Encourage increased fluid intake
B. Ensure adherence to prescribed antibiotic therapy
C. Provide high-protein dietary education
D. Assess pain level
