NURSING CARE OF THE ELDERLY

DEFINITION- GERIATRICS
 Geriatrics is a branch of medical and nursing science that deals
with the treatment and care of disease conditions in old people
including also constructive health practice and prevention of
disease.

NEWTON 1950
 Geriatrics is the positive approach to preserve and to restore
human ability in old age.

NORTON 1965
DEFINITION- GERIATRIC NURSING
 Geriatric nursing is defined as the assessment of nursing
needs of older people, planning and implementing nursing
care to meet those needs and evaluating the effectiveness of
such care to achieve and maintain a level of wellness
consistent with limitations imposed by the ageing process.

AMERICAN NURSES ASSOCIATION 1970


 Geriatric nursing is defined as the specialized nursing care of
the older adults that occur in any setting in which nurses use
knowledge, expertise and caring abilities to promote optimal
functioning.

LENA MYRTLE GOMEZ


GERONTOLOGY
 It means scientific study of the process of aging and the
problems of aged people, it includes the biologic, sociologic,
psychologic and economic aspects.
GERONTIC NURSING
 Nursing of older people that is the art and practice of
nurturing, caring and comforting.
AGE CLASSIFICATION
The old age group is classified into three.
 Young old adults (65 to 74yrs)
 Middle old (75 to 84yrs)
 Old-old adults (85 and above)
CONCEPTS OF AGEING

 Chronologic aging
 Biologic aging
 Psychologic aging
 Social aging
 Cognitive aging
CHRONOLOGIC AGING
 Chronologic age refers to actual amount of time a person
has been alive.
 In other words the number of days, months or years a
person has been alive.
BIOLOGIC AGING(PHYSIOLOGIC AGING)
 Senescence or biological aging is the gradual
deterioration of functional characteristic.
 Biological aging refers to the physical changes that slow
us down as humans get into middle and older years.
 Eg: arteries might clog up or problems with lungs might
make it more difficult for us to breathe.
PSYCHOLOGIC AGING
 It refers to psychological changes, Including those involving
mental functioning and personality, that occurs as human
age.
 Chronologic age is not always same as the biologic or
psychologic age.
 Some people who are 65, can look and act much younger
than some who are 50.
SOCIAL AGING
 It refers to changes in person’s roles and relationships, both
within their network of relatives and friends and informal
organizations such as work place and houses of worship.
 It is also profoundly influenced by the perception of aging that
is part of society’s culture.
 If a society views aging positively, the social aging experienced
by individuals in that society will be more positive and
enjoyable than in society that views aging negatively.
COGNITIVE AGING
 Cognitive ageing is the decline in cognitive processing that occurs as
people get older.

 Age-related impairments in reasoning, memory and processing


speed can arise during adulthood and progress into the elder years.

 Cognitive aging is concerned with the basic processes of learning


and memory as well as with the complex higher- order processes of
language and intellectual competence or executive functioning.
THEORIES OF AGING

Biological
theories of aging

Psycological • Intrinsic biologic theory


theories of aging • External biologic theory
 Biological theories of aging: Physical aging as involuntary process

which leads to cumulative changes in cells, tissues and body fluids.

 Intrinsic biologic theory

Aging changes arise from internal or predetermined cause.

 External biologic theory

Environmental factors lead to structural alterations which in

turn causes degenerative changes.


A. FREE RADICAL THEORY
DENHAM HARMAN-1956
 Free radicals means any molecule that has a free electron and this
property make it react with healthy molecules in a destructive
way.
 This theory emphasizes the mechanism of oxygen use at the
cellular level.
 Free radicals are molecules with an extra cellular charge.
 This charge creates a reaction that alters the structure or function
of the cell membrane.
 Increased unstable free radicals produces harmful effects to
biological system such as chromosomal changes, pigment
accumulation and collagen alteration.
 Oxidation of carbohydrate, protein and fat within the body
produces free radicals.
 Environmental pollutants are external sources of free
radicals.
FREE RADICAL THEORY
B. CROSS LINK THEORY
 Cross-link theory and connective tissue theory asserts that
the molecules of collagen and elastin, connective tissue
components, from bonds that increase cell rigidity.
 Cross linkage is thought to result from chemical reaction that
creates chemical bonds between normally separate
molecules in the body.
C. IMMUNOLOGIC THEORY
 Immune system is responsible for aging.
 An aging immune system is less able to distinguish body cells
from foreign cells as a result it begins to attack and destroy
body cells as if they were foreign.
 Erratic cellular mechanism are thought to cause attacks on
body tissues through auto aggression or immunodeficiency.
D. ERROR THEORY
 This theory focus on the phenomenon of decreased bonding
of protein cells that occurs spontaneously or in response to
stressors such as radiation .
 This stressor results in errors in the synthesis of RNA and DNA
and produces cells with impaired function.
E. WEAR AND TEAR THEORY
 This theory proposes that cumulative damage to vital,
irreplaceable body parts continues as age advances.
 This may leads to death of cells, tissues, organs and finally
the person himself.
F. SOMATIC MUTATION THEORY
 This theory states a random mutation in cells which renders
them inefficient.
 The number of inefficient cells increases with age and this
impairs with the function of organs.
 This is supported by the higher incidence of chromosomal
abnormalities with age.
G.DNA DAMAGE THEORIES
 Aging is caused by accumulated damage to DNA, which in
turn inhibit cells ability to function and express the
appropriate genes.
 This leads to cell death and overall aging of the organism.
H. PROGRAMMED CELLULAR AGING THEORY
 Aging may be a result of an impairment of the cell in
translating necessary RNA as a result of increased turnoffs of
DNA.
 Some segments of DNA become depleted with advancing age
or selected cellular structures seem to change with age so
that DNA transcription is restricted.
PSYCHOSOCIAL THEORIES OF AGING
Age related changes in cognitive function such as
intelligence, memory, learning and problem solving.
A. DISENGAGEMENT THEORIES
CUMMINGS AND HENRY1961

 Aging people withdraw from customary roles and engage in


more introspective, self focused activities.
B. CONTINUITY THEORY
 The continuity or developmental theory states that
personality remains the same behavior becomes more
predictable as people age.
 This theory focuses more on personality and individual
behavior overtime.
C. ACTIVITY THEORY
 Successful aging and life satisfaction depend on maintaining
high level of activity.
 According to this perspective, the maintenance of optimal
physical, mental and social activity is necessary for
successful aging.
 This theory also assumes that older adults have the same
needs as middle age persons.
D. ADJUSTMENT THEORY
 It defines aging as a series of adjustment to retirement, to
grandparenthood, changes in income, to changes in social
life and marital status and to potential deterioration of
health and well being.
