Chapter 4: Health Promotion and Risk Reduction

Health promotion is a proactive process aimed at enabling individuals, families, and communities to increase control over their health and improve overall well-being. Essential lifestyle factors such as nutrition, adequate rest, and good hygiene serve as the foundation for optimal health outcomes.

Multiple determinants influence health, including biology, behavior, social and physical environments, policies, and access to quality health care. Genetics, lifestyle choices such as smoking or inactivity, social support networks, housing conditions, public health interventions, and affordable care all play critical roles in shaping health status.

Determinants of Health

Determinant	Examples
Biology	Genetic predispositions
Behavior	Diet, smoking, lack of exercise
Social Environment	Community engagement, discrimination, social support
Physical Environment	Housing quality, transportation availability
Policies and Interventions	Local, state, or national public health programs
Access to High-Quality Care	Preventive screenings, affordable treatment

Additionally, key social determinants include economic stability, education, food security, community support, and access to the health care system. A modern shift in health strategies emphasizes prevention over cure, aligning with global public health trends.

Theoretical Models in Health Promotion

Pender’s Health Promotion Model (HPM): Considers biological, psychological, and sociocultural factors influencing engagement in healthy behaviors.
Health Belief Model (HBM): Focuses on how individuals perceive health threats and the benefits of taking preventive actions.
Transtheoretical Model (TTM): Describes behavior change in stages—pre-contemplation, contemplation, preparation, action, maintenance, and termination—while recognizing barriers like discomfort or perceived difficulty.
Theory of Reasoned Action (TRA): Suggests that behavior is guided by individual intentions, which are influenced by attitudes and perceived social norms.

Risk Factors

Risk factors are categorized as:

Modifiable: Lifestyle habits (e.g., diet, exercise, smoking).
Non-modifiable: Age, genetics, family history.

Understanding the difference between serving size (recommended dietary amount) and portion size (actual consumed amount) is vital in nutritional education.

Chapter 10: Policy, Politics, Legislation, and Community Health Nursing

Policy is defined as a strategic plan of action adopted by an organization, government, or institution to achieve specific outcomes. Public policy, established through legislative, executive, or judicial processes, addresses issues of broad societal concern.

Types of Policies in Health and Nursing

Policy Type	Description
Health Policy	Declares objectives and strategies for improving population health.
Nursing Policy	Highlights the role of nursing leadership in shaping health care delivery and practice.
Institutional Policy	Governs organizational operations, staff conduct, and service delivery.
Social Policy	Addresses societal well-being at individual and community levels.

Legal Frameworks

Laws derive from legislation, judicial rulings, constitutional mandates, and administrative directives.
Public Health Law focuses on population-level health, covering police powers, disease prevention, and injury control.
Statutes are legislated laws at local, state, or national levels.

Governmental Structure and Roles

Branch	Function
Legislative	Enacts statutory laws.
Executive	Administers and enforces laws via regulatory agencies.
Judicial	Safeguards citizens against abuse, malpractice, and fraud.

Nurses, representing approximately 1 in 44 women voters, have a significant voice in health policy advocacy, reinforcing the profession’s potential for political influence.

Chapter 11: The Health Care System

The U.S. health care system operates through both private and public subsystems.

Private subsystem: Focuses on individual health needs, often funded by private insurance or out-of-pocket payments.
Public subsystem: Addresses population health needs, funded through taxation and government programs.

Chapter 12: Economics of Health Care

Health care economics examines resource allocation, cost management, and funding mechanisms within the system.

Medicare Components

Part	Coverage
A	Hospital insurance (inpatient care).
B	Outpatient services, primary care, and partial out-of-pocket coverage.
C	Medicare Advantage plans including vision, dental, and hearing benefits.
D	Prescription drug coverage.

Medicaid, a state and federally funded program, provides health coverage for low-income individuals and families, determined by income level and family size.

Chapter 14: Environmental Health

Environmental health examines the relationship between environmental factors and human well-being.

Sick Building Syndrome (SBS) occurs when occupants of certain structures experience symptoms like headaches, fatigue, and allergy exacerbation due to poor indoor air quality.

Environmental Exposure Assessment – IPREPARE Model

Step	Description
I	Investigate potential exposures.
P	Present work and possible hazards.
R	Residence and living conditions.
E	Environmental concerns in the community.
P	Past work exposure history.
A	Activities that may increase exposure risk.
R	Referrals and resource access.
E	Education on risk reduction and prevention.
