Gerontology and Geriatrics
• The terms are not interchangeable!• Gerontology is concerned with the social, psychological,
and biological aspects of aging.• Geriatrics is the study of disease in the elderly.
![Page 3: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/3.jpg)
3Geriatrics
• First proposed as a distinct specialty in 1909 by Dr. Ignatz Nascher when he viewed aging as a physiological process and not mere deterioration.
• Geriatrics is concerned with the decline of major body systems in the elderly.
• A geriatric specialist treats disease in the elderly client and attempts to decrease the effects of aging on the body.

4Gerontology
• Developed into an organized field in the 1940s.• Acknowledged that there exist experts in the elderly in many
fields and findings must be integrated. • Studying the physical, mental and social changes in people
as they age• Study of physical process of aging• Study of the effects of the aging population on society and
the effects of society on the elderly• Identification of appropriate treatment and management of
the elderly

History of Gerontological Nursing
“You must not treat a young child as you would a grown person, nor would you treat an old person as you would one in the prime of life.”…“Relation of old age to disease…” American Journal of Nursing, 1904

7Principles of Gerontological Nursing Practice
• Aging is a natural process• Various factors influence the aging process• Nursing of the elderly requires unique information and
skills• There are common needs shared by the elderly and all
ages• Gerontological nursing’s goal is to promote optimum
levels of physical, psychological, social and spiritual health
![Page 8: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/8.jpg)
Competent nursing of the elderly patient
• Holistic: incorporate physical, mental, emotional, and spiritual well being
• Use every opportunity to offer suggestions for healthy aging
• Include health promotion in every plan of care of the elderly patient• Close the gap between “life span” and “healthy life span”
![Page 9: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/9.jpg)
Benefits of healthy aging
• Increased creativity and confidence• Increased coping ability• Increased gratitude and appreciation• Increased insight and acceptance
![Page 10: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/10.jpg)
10Role of the ANA inGerontological Nursing Care
• Responsible for defining scope and standards of nursing practice
• Established the Division of Geriatric Nursing Practice in 1966 with the goal of creating standards for quality nursing care for the elderly
• Changed the name to Division of Gerontological Nursing Practice in 1976
![Page 11: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/11.jpg)
11
The Aging Population
• Persons older than 65 comprise 12% of the US population
• Increasing life expectancy• 20% of the population will be older than 65 by 2020
![Page 12: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/12.jpg)
12
Subsets of the Elderly
• Young-old: 65 to 74 years
• Old: 75 to 84 years
• Old-old: 85 to 100 years
• Elite old: over 100 years
![Page 13: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/13.jpg)
13The Baby Boomers
• Born between 1946 and 1964• Most have children, but fewer in number• Best educated generation yet• Higher income• Favor more casual dress• Enjoy technology• Less leisure time• Interest in health and fitness
![Page 14: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/14.jpg)
14
Accomplishments of Old Age
• Adequate nutrition• Maintaining safety• Preserving body’s normal
functions• Meeting and coping with
crises• Adapting to change• Learning new skills
![Page 15: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/15.jpg)
15Recognizing Inner Resources of the Elderly
• Promotes normalcy, independence and individuality
• Reduces risks associated with dependency, e.g., failure to thrive
• Recognizes individual attributes of wisdom, experience and competence
![Page 16: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/16.jpg)

Associated Costs and Funding
• In 2005, long term health care accounted for 12% of all healthcare expenditure
• 70% of this figure was covered by Medicaid and Medicare
• 18% was paid by patients and families
![Page 17: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/17.jpg)
17Myths of Aging
• “Old” means being sick• Older people cannot learn new information• Health promotion is wasted on older people• The elderly do not pull their own
weight• It is too late to change bad habits
in the elderly• Older people have no interest
in sex
![Page 18: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/18.jpg)
18Common Characteristics of Centenarians (1)
• Biocognitive Theory (Mario Martinez)• Absence of envy• Live in the present, being optimistic about the present and the
future• No sense of aging, don’t tell their age (prevents being
“pegged”)• Usually underweight, not obese• Active• No concept of retirement or middle age, no marker for
biology to follow
![Page 19: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/19.jpg)
19Common Characteristics of Centenarians (2)
• Rarely seek medical advice unless complaint is significant
• Usually die by accident or in sleep…death is peaceful and without lamenting
• Low protein, high complex carbohydrate diet• Live in subcultures that revere the elderly• Drink alcohol prudently, not addictively• There are no atheists, a belief in a benign, not wrathful,
power
![Page 20: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/20.jpg)
20Common Characteristics of Centenarians (3)
• Longevity in the family is not a requirement• Definite sense of humor• Forgive easily• They are negotiators• Have commitment to community, a sense of service• Fearless about life’s challenges• Believe they are loveable
![Page 21: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/21.jpg)
21
Value of Theories of Aging
• Insight into understanding the process of aging• Promote aging in a healthy fashion• Postpone or minimize negative effects• Emphasis is not on prolonging life• Goal is to• Keep the client healthy• Keep the client active• Maximize quality of life
![Page 22: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/22.jpg)
22
Biological Theories of Aging
• Biological theories attempt to explain these variations:• Rate of aging
varies betweenindividuals
• There is variation in rates of aging within one individual
![Page 23: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/23.jpg)
23
Genetic Theories of Aging
• Premise: life expectancy is inherited due to a genetic program
• Cellular theory—senescence takes place at the cellular level• Error theory—decline is caused
by genetic mutations within each organ
• Failure of a growth substance or excessive production of an aging substance
![Page 24: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/24.jpg)
24
Psychosocial Theories of Aging
• These theories integrate an individual’s• Mental capacities• Methods of behavior• Personal feelings• Coping mechanisms• Values, attitudes and beliefs
![Page 25: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/25.jpg)
25
Disengagement Theory
• Society and the individual mutually agree to withdraw from one another
• The individual is free to become introspective• Society enjoys the benefit of transferring power and
resources to the young and continues
Is this a “win-win” on an ice floe?
![Page 26: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/26.jpg)
26
Disengagement theory problems…
“I don’t want to!”
![Page 27: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/27.jpg)
27Activity Theory
• “Longevity through denial”• Perpetuating the middle-age
lifestyle• Maintaining an active life
while adjusting for biologicalchange
• Gradually substitute mental activities for physical ones
![Page 28: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/28.jpg)
28Continuity Theory
• AKA Developmental Theory
• “PNC”—people never change
• Recognizes the unique qualities of each individual
• Those qualities guide the individual through the aging process and adaptation to change
![Page 29: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/29.jpg)
29
Developmental Tasks Theory
• Specific tasks must be completed in each stage of life before moving on successfully
• If successful, the person finds meaning in each stage and in life as a whole
![Page 30: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/30.jpg)
30Developmental Tasks Throughout the Lifespan
• Coping with loss and change• Establishing meaningful roles• Exercising independence and control• Finding purpose and meaning in life
![Page 31: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/31.jpg)
31Major Tasks of the Elderly(Robert Butler and Myrna Lewis)
• Adjustment to infirmities• Satisfaction with the life lived• Preparation for death
![Page 32: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/32.jpg)
32
Specific Challenges of the Elderly(Robert Peck)
• Ego differentiation vs role preoccupation• Body transcendence vs body preoccupation• Ego transcendence vs ego preoccupation
All contribute to the effectiveness of completing ego integrity vs despair
![Page 33: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/33.jpg)
33Nutrition and aging
• Nutritional needs change as the individual ages• Failure to adjust nutrition accordingly can contribute to
the aging process
![Page 34: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/34.jpg)
34
Reduced calorie need in the older adult
• Less lean body mass and increased adipose tissue• BMR declines 2% for each decade of life• Activity level
usually declineswith age
![Page 35: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/35.jpg)
35
Dehydration risk factors
• Age related physical changes: decreased total body water due to less lean body mass
• Reduced access to fluids• Fear of incontinence and nocturia• Increased insensitive fluid loss
![Page 36: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/36.jpg)
36
Specific threats to Hydration
• Reduced intracellular fluid with age• Reduced margin of safety• Minimum 1500 mL per day• Reduced thirst sensation• Fear of incontinence• Decreased availability of fluid• Physical impairment• Altered mood or cognition• GI distress
![Page 37: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/37.jpg)
37
Signs of early Dehydration
• Patient may present with altered mental status, lethargy, syncope
• Mild dehydration: decreased skin turgor, dry mucous membranes, orthostatic hypotension
• Symptoms consistent with mild dehydration may exist in patients who are normally hydrated
![Page 38: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/38.jpg)
38
Advanced dehydration
• Dark urine with decreased output• Confusion, lethargy• Headache, light-headedness• Eyes sunken• Dry mucous membranes and
axillae• Furrows in tongue• Postural changes in vital signs
![Page 39: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/39.jpg)
39Tufts University MyPlate for older adults
• Dark green vegetables, colorful vegetables, dried beans—2 ½ cups every day
• Fresh, frozen, dried, canned fruits— 1 ½ cups every day• Grains—6 ounces every day• Protein foods—5 ounces every day• Dairy—3 cups every day
![Page 40: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/40.jpg)
40
Tufts additions to traditional food guide
• Acknowledges the possible need for supplements
• Includes physical activity as part of daily routine
• Water is included
• Recommendations for protein unchanged
![Page 41: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/41.jpg)
41Role of protein in the diet of the elderly client
• Sarcopenia—age related loss of muscle mass, strength, and function
• Protein breakdown exceed protein synthesis as the body ages
• RDA is unchanged: 0.8g/kg body weight
![Page 42: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/42.jpg)
42
Dietary supplements—nursing considerations
• Some elderly clients take supplements for nonconventional reasons
• Clotting is affected by fish oils, garlic, ginseng, ginko biloba, baby aspirin
• Quality and content of many supplements are neither regulated nor standardized
![Page 43: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/43.jpg)
43
Body measurements (anthropometrics)
• Weight—unintentional loss of 5% in 1 month or 10% in 6 months is significant
• Height• Body mass index = (weight in pounds x 703)
(height in inches)2
![Page 44: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/44.jpg)
44Nutritional history
• Use of Mini Nutritional Assessment (MNA)• “Tell me what you ate yesterday.”• Risk factors:• Inability to feed oneself• Chewing, swallowing problems, mouth pain• Changes in taste• Leaves > 25% food uneaten at most meals
![Page 45: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/45.jpg)
45Strategies to improve nutrition--1
• Indigestion, food intolerance—client may chose to use antacids or limit food intake• Have several small meals instead of 3 large ones• Avoid fried foods• Remain in high Fowler’s position for at least 30 minutes• Adequate fluid for motility promotion
![Page 46: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/46.jpg)
46
Strategies to improve nutrition--2
• Anorexia• Identify the cause• High calorie diet• Referral to social programs• Psychological/psychiatric
referral• Weight loss > 5% in 1 month
and >10% in 6 months is significant
![Page 47: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/47.jpg)

![Page 49: Gerontological Nursing](https://reader035.vdocuments.mx/reader035/viewer/2022062410/568165c1550346895dd8c6d3/html5/thumbnails/49.jpg)
49
Strategies to improve nutrition--4
• Constipation• Fluids• Fruits, vegetables• Activity• Increase fiber intake cautiously• Consider laxatives only when other methods are
unsuccessful

Nursing diagnoses--nutrition
• Imbalanced nutrition—more/less than body requirements (also, “Risk for”)
• Impaired swallowing; Risk for aspiration• Excess/deficient fluid volume
(also, “Risk for”)• Failure to thrive (adult)• Impaired skin integrity
(also, “Risk for”)
