Lessons 1-4 Flashcards
What is health?
Objective process characterized by functional stability, balance, and integrity
“a state of complete physical, mental, and social well-being, and not merely the absence of disease or infirmity” (WHO, 1947)
“the extent to which an individual or group is able, on the one hand, to realize aspirations and satisfy needs; and, on the other hand, to change or cope with the environment. Health is, therefore, seen as a resource for everyday life, not the objective of living; it is a positive concept emphasizing social and personal resources, as well as physical capacities” (WHO, 1984)
What is wellness?
A subjective experience or state of being
A state of health that is optimal for a person at any particular point in time
Includes physical, psychological, spiritual, social, and economic well-being
“The fulfillment of one’s role expectations in the family, community, place of worship, workplace, and other settings” (Smith et al., 2006)
Perceptions of well-being can define quality of life
What is disease?
An objective state of ill health, the pathological process of which can be detected by medical science
What illness?
A subjective experience of loss of health.
Classification of health?
Health as stability
The maintenance of physiological, functional, and social norms, and encompasses views of health as a state, as a process, as adaptation, and as homeostasis
Health as actualization
The actualization of human potential. Within this concept, the terms health and wellness are often used interchangeably
Health as actualization
The actualization of human potential (health and wellness often used interchangeably)
Healthy as actualization and stability
The realization of human potential through goal-directed behaviour, competent self-care, and satisfying relationships with others, while adapting to meet the demands of everyday life and maintain harmony with the social and physical environments
Health as resource
Includes capacities to fulfill roles, meet demands, and engage in the activities of daily life (originally emerged in the Ottawa Charter for Health Promotion)
Health as unity
Reflecting the whole person as process and is synonymous with self-transcendence or actualization
What are the dimensions of health and well-being? (What do you need to feel)
Feeling vitalized and full of energy.
Having satisfying social relationships.
Having a feeling of control over one’s life and living conditions.
Being able to do things that one enjoys.
Having a sense of purpose.
Feeling connected to community.
What is the medical approach to health?
A stability orientation to health
Thought that medical intervention restores health
Health problems defined primarily as physiological risk factors
Focus on treatment of disease
Downstream thinking approach
Less focus on health promotion and disease prevention
What is a behavioural approach to health?
Lalonde report: A New Perspective on the Health of Canadians (1974) resulted in a shift from a medical to behavioural approach to health
Defined health determinants as lifestyle, environment, human biology, and the organization of health care (health field concept)
Lifestyle behaviours contribute to chronic diseases and injuries
Places responsibility for health on the individuals – focuses on health promotion strategies like education and social marketing
Based on the assumption that if people know the risk factors for disease, they will engage in healthy behaviours
What is a socioenvironmental to health?
Shift to the notion that health-related behaviours could not be separated from social contexts (environments)
Health is inextricably linked to social structures (e.g., poverty, air pollution, poor water quality, workplace hazards)
Responsibility of health on society, not just individuals
Upstream thinking (policy interventions)
Health disparities and inequities
What are social determinate of health?
Income
Food
Gender
Social safety network
Housing
Indigenous status
Education
Social exclusion
Race
Unemployment and job security
Early childhood development
Disability
Employment and working conditions
Health services
Equity vs. Equality
Equity- Same treatment.
Equality- The systemic barrier has been removed.
What is primary prevention?
An intervention is implemented before there is evidence of a disease or injury.
Reduces or eliminates causative risk factors (risk reduction)
Good health habits
Diet and exercise
Smoking cessation
Vaccinations
Behavior management
What is secondary prevention?
An intervention is implemented after a disease has begun, but before it is symptomatic.
Early identification through screening and treatment.
Testing such as mammograms and colonoscopy.
Screening such as diabetes, cardiovascular disease, or other disease.
Implement early changes to decrease any long-term effects and possibly eliminate the disease process all together.
What is tertiary prevention?
An intervention is implemented after a disease or injury is established.
Prevent sequelae, stop the disease process from getting worse.
Already have a chronic disease like diabetes or hypertension.
Measures are taken to reduce the impact of chronic diseases.
For example keeping glucose and blood pressure under control, reducing risk of comobidities.
What are health promotion strategies? (BCSDR)
Build- health public policy.
Create- supportive environments.
Strengthen- community action.
Develop- personal skills.
Reorient- health services.
What are the principles of primary health care?
Accessibility: availability of health services to all Canadians regardless of age or geographic location
Health promotion: process of enabling people to increase control over and improve their health (addresses the DoH)
Public participation: having people being active participants in making decisions about their health care and health of their communities
Interprofessional, interdisciplinary, and intersectoral collaboration: people working across professions and sectors to deliver the necessary care to address health and the DoH
Use of appropriate skills and technology: methods of care, service delivery, procedures, equipment that are socially acceptable and affordable
Aging and health
Gerontology: The care of older persons
Canada, and the world, have an aging population
What are the issues with grouping all ‘older persons’ into the same category?
Life is likely very different for those at 60, 70, 80, 90
In Canada, those over 65 are often called ‘seniors’
You may also hear the term ‘older adult’ or ‘older person’
An Indigenous person over 65 is often referred to as an ‘elder’
Aging and healthcare
Patient centred care
Understanding the factors influencing health and health care in aging.
Ageism
Attitudes, interest, experience, and confidence of students and HCPs.
What are the factors associated with successful healthy aging? (6 words)
Social
Environmental
Cultural
Spiritual
Psychological
Biological
Health promotion and aging
Nurses play a key role in helping older people to achieve their optimal level of wellness.
Nurses have the knowledge to provide support, and education, and empower older persons to strive for wellness.
Nurses have the skills to conduct comprehensive assessments and collaborate with older people and their families to develop person-centred plans of care.
Terminology commonly used in health care around older afults
Gerontology: the multidisciplinary study of older persons concerned with the physical, mental, and social aspects and implications of aging
Geriatrics: a medical specialty focused on the care and treatment of older persons
Gerontological nursing: an evidence-based nursing specialty that addresses the unique physiological, social, psychological, developmental, economic, cultural, spiritual, and advocacy needs of older persons. Focused on the process of aging
Common myths about aging
Older people aren’t interested in the outside world
Older people don’t want or need close relationships
Older people contribute little to society
As you age, you get more set in your ways
Mental and physical deterioration are inevitable in older age
Older people are impoverished
Older people are not interested in sex or intimacy
Older people can’t make good decisions about important issues
Older people lose their desire to live
Science has answered all of our questions about aging
What are the biological theory of aging?
Error (stochastic) theories
- Explain aging as the result of an accumulation of errors in the synthesis of DNA and RNA
- Wear-and-tear theory
- Cross-link theory
- Oxidative stress (free radical theory)
Programmed aging (nonstochastic) theories
- Explain aging as a process that is predetermined or ‘preprogrammed’ at the cellular level
- Neuroendocrine-immunological theory
What are sociological theories of aging?
Activity Theory
Continuity Theory
Age-Stratification Theory
Social Exchange Theory

Accepting one’s self as an aging person
Maintaining satisfactory living arrangements
Redefining relationships with adult children
Findings ways to maintain quality of life
Spirituality and aging?
Spiritual well-being can be considered the ability to experience and integrate meaning and purpose in life through connectedness with self, others, art, music, literature, nature, or a power greater than oneself
What are common physiological changes associated with aging? (Systems)
Integumentary System
- Skin becomes thinner, loses moisture and elasticity (with fat loss), glandular atrophy, spots may appear on the skin (pigmentation changes), skin becomes paler, hair loss, hair turning grey or white, nail thickening and hardening.
Musculoskeletal System
- Tendons, ligaments, joints dry and harden (less flexible), bone mass decreases, degenerative joint changes, sarcopenia, replacement of lean mass by adipose tissue, thinning of vertebral discs.
Cardiovascular System
- Stiffening of the myocardium and blood vessels, thickening of left ventricle, reduced blood flow, stroke volume, and cardiac output, decreased response to sudden changes in oxygen demand, blood vessel thickening, venous valve efficiency.
Respiratory System
- Loss of elastic recoil, stiffening of the chest wall, inefficiency in gas exchange, increased air flow resistance, fewer alveoli, decreased cough reflex.
Genitourinary System
- Blood flow, ability to regulate body fluids, loss of nephrons, decreased bladder capacity.
Endocrine System
- Changes in thyroid structure and diminished secretion of hormones.
Reproductive
- Female: changes after menopause, decrease in estrogen.
- Male: enlargement of prostate.
Gastrointestinal System
- Dry mouth (xerostomia), decreased saliva, vulnerable teeth, periodontal disease, presbyesophagus (less effective propulsion), decreased gastric motility and volume, decreased nutrient absorption in intestines
Neurological System
- Decreased number of neurons, sleep changes (loss of deep sleep), increased risk for injury (loss of nerve endings in the skin and changes in proprioception), sensory alterations (visual and auditory)
Immune System
- Decrease in innate immunity, adaptive immunity, and self-tolerance decreases T-cell function which can create an autoimmune response
What are functional changes?
Functional status refers to the ability for an older person to safely participate in activities of daily living (ADLs)
- Often linked to independence
Physical, psychosocial, and cognitive health all impact functional status
Factors that promote function: diet, activity, regular visits to and follow-up with health care providers, meaningful activities, stress management and avoidance of substance use
A change in functional status can be an indicator of a change or decline in health
What are ADLs?
Activities of daily living is a term used in healthcare to refer to people’s daily self-care activities.
Dressing
Ambulating
Bathing
