,1. Which of the following best describes the primary focus of community health nursing?
A) Providing direct patient care in acute care hospital settings
B) Promoting and preserving the health of populations
C) Administering medications to individual clients in clinics
D) Performing rehabilitation services for the disabled
Correct Answer: Promoting and preserving the health of populations
Rationale: Community health nursing is population-focused, emphasizing health promotion and
disease prevention for entire communities rather than individual acute care . This distinguishes
it from hospital-based nursing, which focuses on individuals. The goal is to improve the health
of the community as a whole through organized effort .
2. According to the World Health Organization (WHO), health is best defined as:
A) The absence of disease or infirmity
B) A state of complete physical, mental, and social well-being
C) The ability to perform activities of daily living independently
D) Freedom from chronic illness
Correct Answer: A state of complete physical, mental, and social well-being
Rationale: The WHO defines health holistically as a state of complete physical, mental, and
social well-being, emphasizing that it is not merely the absence of disease . This definition
underscores that health is a positive resource for living, highlighting social and personal
capacities, not just a physical objective .
3. The three core functions of public health, as established by the Institute of Medicine, are:
A) Assessment, Policy Development, and Assurance
,B) Assessment, Treatment, and Evaluation
C) Prevention, Intervention, and Rehabilitation
D) Surveillance, Diagnosis, and Treatment
Correct Answer: Assessment, Policy Development, and Assurance
Rationale: The three core public health functions are Assessment (systematically collecting data
on the population), Policy Development (using scientific knowledge to develop health policies),
and Assurance (ensuring essential community health services are available) . These functions
guide community health nursing practice and focus on population-level interventions.
4. The study of the distribution and determinants of health and disease in human populations is
called:
A) Sociology
B) Epidemiology
C) Biostatistics
D) Environmental science
Correct Answer: Epidemiology
Rationale: Epidemiology is the study of the distribution and determinants of health-related
states and events in populations . It is the foundation of public health, helping community
health nurses identify disease patterns, risk factors, and populations at risk to guide
interventions.
5. According to the epidemiological triangle, the three components necessary for disease
transmission are:
A) Person, place, and time
, B) Host, agent, and environment
C) Susceptibility, exposure, and outcome
D) Primary, secondary, and tertiary
Correct Answer: Host, agent, and environment
Rationale: The epidemiological triangle is a model that explains the interaction between the
host (susceptible individual), the agent (cause of the disease), and the environment (external
factors that allow transmission) . This model helps community health nurses understand disease
causality and develop prevention strategies.
6. Which of the following is the single leading preventable cause of death in the United States?
A) Alcohol use
B) Firearms
C) Overweight and obesity
D) Tobacco use
Correct Answer: Tobacco use
Rationale: Tobacco use is the single leading preventable cause of death in the United States,
contributing to numerous chronic diseases, including lung cancer, heart disease, and COPD .
Community health nurses play a key role in tobacco prevention and cessation programs.
7. The three levels of prevention in community health nursing are:
A) Primary, secondary, and tertiary
B) Primary, secondary, and quaternary
C) Individual, family, and community
A) Providing direct patient care in acute care hospital settings
