Chapter 24- condensed

Aging is a gradual process of development and maturation influenced by biological, psychosocial, and environmental factors. Changes begin in middle adulthood and become more noticeable in older adulthood.

Aging itself is normal. Disease and disability are not automatically normal parts of aging.

The chapter’s nursing concepts are:

Advocacy • Cognition • Development • Family • Identity • Sexuality

2. Biological Theories of Aging

No single theory completely explains aging.

Nonstochastic Theories

Aging is largely predetermined.

Genetic Theory

Genes influence a biologic/genetic clock that affects the timing and rate of processes such as cell division.

Telomere-telomerase hypothesis: cells have a finite number of divisions, making cellular death partly preprogrammed.

Neuroendocrine Theory

The pituitary and hypothalamus help regulate body processes. With aging, these control mechanisms become less effective.

Immunity Theory

Immune function declines with age.

Immunosenescence = age-associated decline in immune function.

The thymus decreases in size and function, contributing to greater risk for infection, immune disorders, and cancer.

Stochastic Theories

Aging results partly from random cellular damage.

Wear-and-Tear Theory

Repeated metabolic activity and adaptation to stress eventually exhaust cells.

Cross-Linkage Theory

Cross-links accumulate and interfere with normal cell function, contributing to decreased elasticity and flexibility.

Free Radical Theory

Free radicals formed during metabolism can damage cell membranes, DNA, and protein synthesis. Damage accumulates over time.

3. Middle Adulthood

Middle adulthood = approximately ages 40–65.

This stage includes gradual physical changes, continued cognitive ability, role changes, greater responsibility, and increasing awareness of mortality.

Normal Physiologic Changes in Middle Adulthood

• Fat redistribution

• Drier skin

• Wrinkles

• Gray hair

• Hair loss in some males

• Decreased cardiac output

• Gradual decrease in muscle mass, strength, and agility

• Bone calcium loss

• Increased fatigue

• Decreased near vision: presbyopia

• Decreased high-pitched hearing: presbycusis

• Decreased hormone production

Female Hormonal Changes

Menopause usually occurs between about 40 and 55 years due to declining ovarian function and reduced estrogen/progesterone.

Possible effects:

• Hot flashes

• Mood swings

• Fatigue

Loss of estrogen increases risk for:

• Osteoporosis

• Heart disease

Male Hormonal Changes

Andropause involves gradual decline in androgen levels. Some sexual potency may decrease, but reproduction may remain possible.

4. Cognitive Development in Middle Adulthood

Cognitive and intellectual ability changes little from young adulthood.

Middle-aged adults may:

• Remain strong problem solvers

• Be highly motivated to learn when information is relevant

• Take slightly longer to respond

Key Distinction

Longer response time does not mean decreased intelligence.

5. Psychosocial Development in Middle Adulthood

Common experiences include:

• Increased personal freedom

• Greater economic stability

• Deeper relationships

• Greater responsibilities

• Awareness of mortality

• Reevaluation of goals and accomplishments

6. Developmental Theories: Middle Adulthood

Erikson

Generativity vs. Stagnation

Generativity includes:

• Guiding the next generation

• Accepting middle-age changes

• Adjusting to aging parents

• Reevaluating goals and accomplishments

Stagnation may involve excessive self-focus and concern with personal needs.

Memory Cue

Middle age = Generativity = guiding/giving to the next generation.

Havighurst

Tasks include:

• Accepting physical changes

• Maintaining satisfying employment

• Helping children become responsible adults

• Adjusting to aging parents

• Relating to spouse/partner as a person

Levinson

The adult may:

• Continue an established lifestyle, or

• Reorganize life during a midlife transition

Gould

• 35–43: increased inward reflection

• 43–50: greater awareness of lifespan limits and interest in relationships/community

• 50–60: increased self-satisfaction, companionship, and health concerns

7. Family, Employment, and Relationships in Middle Adulthood

Employment

Adults may:

• Change careers

• Return to school

• Become self-employed

• Work from home

• Reduce workload

• Focus more on retirement and financial security

Spousal Relationships

Relationships may become more secure but can also be affected by:

• Physical changes

• Energy changes

• Sexual changes

• Unmet family/career goals

• Divorce or extramarital relationships

Loss of a spouse can result in:

• Grief

• Role change

• Reduced income

• Social and lifestyle changes

Sandwich Generation

Middle-aged adults may simultaneously care for:

• Adult children

• Aging parents

Stress may be:

• Financial

• Emotional

• Logistical

• Resource-related

Empty Nest

The textbook notes that many adults enjoy the increased:

• Space

• Time

• Independence

when children leave home.

8. Moral and Spiritual Development: Middle Adulthood

Kohlberg

Adults may remain at the conventional level or progress to postconventional morality, where the rights of others take greater importance.

Fowler

Some adults become:

• Less rigid

• More accepting of paradox

• More aware of symbolism and bias

• More capable of considering multiple perspectives

9. Health of the Middle-Aged Adult

Health problems may be related to:

• Lifestyle

• Family history

• Developmental/situational crises

• Environment

Major health problems listed include:

• Cancer

• Cardiovascular disease

• Unintentional injury

• Suicide

• Chronic respiratory disease

• Liver disease

• Diabetes

• Cerebrovascular disease

• Kidney disease

• Septicemia

• Rheumatoid arthritis

• Obesity

• Alcoholism

• Depression

Reduced activity while maintaining previous eating habits may contribute to:

• Obesity

• Atherosclerosis

• Hypertension

• Coronary artery disease

• Renal failure

• Diabetes

Smoking and alcohol increase risk for cancer, respiratory disease, and liver disease.

10. Nursing Health Promotion: Middle Adulthood

The nurse promotes health through teaching, role modeling, and self-care.

Teach:

• Diet low in fat/cholesterol

• Fruits, vegetables, fiber

• Moderate sugar, salt, sodium

• Regular exercise

• Alcohol in moderation

• No smoking

• Recommended screenings, exams, and immunizations

11. Older Adulthood

Older adulthood is generally defined as 65+, although the chapter emphasizes that 65 is an arbitrary cutoff.

Categories:

• Youngest-old: 65–74

• Middle-old: 75–84

• Oldest-old: 85+

Older adults vary greatly in:

• Health

• Cognition

• Independence

• Finances

• Family structure

• Social involvement

Key Principle

Chronologic age alone does not determine function.

12. Ageism

Ageism = prejudice and discrimination against older adults because of age.

Common stereotypes incorrectly assume older adults are:

• Dependent

• Sick

• Cognitively impaired

• Unable to learn

• Uninterested in sex

• Unproductive

• Isolated

These assumptions may lead to discriminatory nursing care.

13. Common Myths vs. Reality

14. Functional Health

Functional health = ability to perform usual and desired activities while maintaining independence and control.

Older adults may have chronic disease and still be functionally healthy.

Concept Mastery

The ability to adapt, not how quickly adaptation occurs, is important in determining health.

15. Normal Physiologic Changes in Older Adults

The biggest overall change is decreased physiologic reserve.

This creates a more fragile balance and makes older adults more vulnerable during illness, injury, surgery, or emotional stress.

Body Systems

Important GU Point

Bladder capacity decreases and nocturia may increase, but incontinence itself should not automatically be considered normal aging.

16. Sarcopenia

Sarcopenia = loss of muscle mass associated with aging.

May include:

• Decreased grip strength

• Slower gait

• Decreased physical function

Sarcopenic Obesity

Loss of muscle mass combined with increased body fat.

The textbook identifies:

• Resistance exercise

• Adequate dietary protein

as useful management strategies.

17. Cognition in Older Adults

Normal aging may involve:

• Longer processing time

• Longer response time

• Mild recent-memory changes

However:

• Intelligence may increase into the 60s

• Learning continues throughout life

• Long-term memory usually remains intact

Nursing Actions

• Slow the pace of care

• Allow time for responses/questions

• Encourage notes, calendars, and schedules

Key Distinction

Slower processing ≠ confusion.

18. Psychosocial Development and Identity

Self-concept is often stable.

Older adults may replace earlier roles with:

• Volunteering

• Community leadership

• Hobbies

• New work

Threats to identity include:

• Retirement

• Loss of health

• Reduced income

• Loss of driving

• Social isolation

19. Psychosocial Theories of Aging

Disengagement Theory

Older theory suggesting natural withdrawal from roles. Later research showed isolation is not necessarily desirable.

Activity Theory

Successful aging involves continued:

• Activity

• Function

• Social participation

Continuity Theory

Healthy aging involves maintaining familiar patterns and behaviors from earlier life.

20. Erikson: Older Adulthood

Ego Integrity vs. Despair

Ego Integrity

The older adult looks back with:

• Pride

• Meaning

• Acceptance

• Few regrets

• Acceptance of aging and mortality

Despair

May involve:

• Regret

• Hopelessness

• Worthlessness

• Missed opportunities

• Fear there is not enough time left

21. Life Review and Reminiscence

Older adults may tell stories and reflect on past experiences.

This helps:

• Find meaning

• Restructure experiences

• Connect past with present

• Adapt to current circumstances

• Support ego integrity

Reminiscence may also be useful in mild to moderate dementia.

22. Havighurst and Gerotranscendence

Havighurst: Older Adulthood

Successful aging involves:

• Maintaining relationships

• Adapting to new roles

• Finding meaningful roles

• Remaining flexible

Gerotranscendence

May include:

• Wisdom

• Spirituality

• Maturity

• Changed views of time and space

• Less emphasis on superficial relationships

• Increased life satisfaction

23. Major Adjustments in Older Adulthood

Older adults may need to adapt to:

• Declining strength

• Chronic illness

• Retirement

• Reduced income

• Spouse/partner illness

• Loss

• Living arrangement changes

• Social-role changes

• Family-role reversal

24. Social Isolation

Social isolation = feeling alone due to limited meaningful relationships.

Contributors may include:

• Poor health

• Transportation issues

• Limited income

• Loss of friends/family

• Ageism

Do Not Confuse

Social isolation: feeling alone
Ineffective coping: difficulty adapting/responding to change

Ineffective coping may lead to social isolation.

25. Family and Role Reversal

Families may provide:

• Transportation

• Meals

• Housing

• Emotional support

• Medical assistance

Adult children may become caregivers for aging parents.

This may create:

• Financial stress

• Emotional stress

• Caregiver burden

Nursing Concept: Family

Assess the entire family system, including strengths, limitations, resources, and caregiver concerns.

26. Housing and Living Arrangements

Most older adults live in the community.

Ability to remain safely at home depends on:

• Functional health

• Transportation

• Income

• Family support

• Home environment

• Available services

Housing options include:

• Home modification

• Accessory apartment

• Assisted living

• Adult family/group home

• Continuing care retirement community

• ECHO housing

• Home sharing

• Long-term care facility

• NORC

• Senior retirement community

27. Sexuality

Sexuality continues throughout life.

Older adults still have needs for:

• Intimacy

• Touch

• Sexual expression

• Emotional closeness

Nursing care may include:

• Privacy

• Hygiene/grooming

• Barrier protection education

• Water-soluble lubricant for females

• Referral for erectile dysfunction concerns

Nursing Principle

Do not assume older age eliminates sexual desire or activity.

28. Chronic Illness

The likelihood of chronic illness increases with age.

Major conditions mentioned include:

• Heart disease

• Cancer

• Chronic respiratory disease

• Stroke

• Alzheimer disease

• Diabetes

Critical Distinction

Aging = normal process
Chronic illness = pathologic process

They can occur together, but they are not the same.

29. Polypharmacy

Polypharmacy = use of many medications simultaneously.

Risks:

• Adverse effects

• Toxicity

• Drug-drug interactions

• Medication duplication

• Problems with unmonitored OTC medications

Nursing Principle

A new symptom may be a medication effect, not simply “old age.”

30. Falls and Accidental Injury

Older adults are at higher risk because of:

• Vision/hearing changes

• Muscle loss

• Reduced strength

• Slower reflexes

• Slower reaction time

• Sensory changes

• Chronic illness

• Medications

Falls are the most common cause of injury and hospitalization in older adults.

Textbook points:

• More than 25% fall each year

• One fall increases risk of another

• About 1 in 5 falls causes serious injury

• More than 95% of hip fractures occur from falls

31. Dementia, Delirium, and Depression: The 3 Ds

Dementia

Usually:

• Chronic

• Gradual

• Progressive

Types mentioned:

• Alzheimer disease

• Vascular dementia

Progression

Early: forgetfulness, impaired judgment
Moderate: increased confusion, forgets family, disorientation
Severe: loss of self-care abilities, constant supervision needed

Sundowning Syndrome

A person with dementia may become increasingly:

• Confused

• Restless

• Agitated

after dark.

May include:

• Wandering

• Hallucinations

• Delusions

• Paranoia

Delirium

Delirium is:

• Acute

• Fluctuating

• Related to an underlying cause

• Often reversible when the cause is treated

Possible causes:

• Drug interactions

• Circulatory problems

• Metabolic problems

• Nutritional deficiencies

• Worsening illness

Six Major Risk Factors

• Cognitive impairment

• Sleep deprivation

• Immobility

• Visual impairment

• Hearing impairment

• Dehydration

Nursing Care

• Frequent reorientation

• Provide eyeglasses/hearing aids

• Reduce isolation

• Encourage family presence

• Assess baseline cognition

• Promote sleep and comfort

Depression

Depression is not normal aging.

Possible signs:

• Prolonged sadness

• Sleep disturbance

• Weight change

• Difficulty concentrating

• Irritability

• Anger

• Loss of interest

• Vague pain

• Crying

• Fatigue

• Suicidal thoughts

• Preoccupation with death

The chapter notes that hopelessness may be especially associated with suicidal intent.

32. 3 Ds Comparison

33. Cascade Iatrogenesis

Cascade iatrogenesis = one intervention/problem causing a chain of additional adverse events.

Example from the textbook:

Confusion → wandering → fall → hip fracture → hospitalization → urinary catheter → UTI → antibiotics → possible resistant organism

34. Elder Abuse

Types:

• Physical

• Sexual

• Emotional/psychological

• Financial exploitation

• Neglect

Possible Warning Signs

• Injuries inconsistent with explanation

• Untreated injuries

• Suspicious bruising/cuts

• Concerning caregiver interaction

• Abnormal voice tone or behavior

Nursing Response

• Speak privately with the older adult

• Document objectively

• Include direct quotes when appropriate

• Follow reporting requirements

• Use trained professionals to separately interview the suspected abuser

Nursing Concept: Advocacy

Protect:

• Safety

• Rights

• Autonomy

• Access to resources

35. Fulmer SPICES

Use SPICES to screen for common older-adult concerns:

S — Sleep disorders
P — Problems with eating/feeding
I — Incontinence
C — Confusion
E — Evidence of falls
S — Skin breakdown

36. Nursing Actions to Promote Health

Physiologic Function

• Maintain physiologic reserves

• Ongoing assessment

• Early detection of problems

• Review prescribed and OTC medications

• Skin care

• Balance rest/activity

Cognitive Function

• Slow the pace of care

• Allow response time

• Ensure glasses and hearing aids are used and functioning

Psychosocial Needs

• Recognize hospitalization/relocation as major stressors

• Assess strengths and support systems

• Include cultural/spiritual values

• Set mutual goals

• Involve the patient in decisions

• Encourage self-care, reminiscence, and life review

Nutrition

Assess:

• Teeth/dentures

• Chewing

• Height/weight

• Eating patterns

• Malnutrition

• Swallowing

Sleep

• Discourage excessive napping

• Assess bedtime routine

• Assess pain, medications, anxiety, depression

Elimination

• Good lighting

• Safety bars

• Adequate fluid/fiber intake

Activity

• Assess gait/walking ability

• Provide cane/walker if needed

• Reduce clutter

• Improve lighting

• Remove rugs

• Allow extra time

37. Acute Illness and Hospitalization

Older adults have greater complication risk because of reduced physiologic reserve.

Hospitalization may contribute to:

• Multisystem dysfunction

• Iatrogenic complications

• Delirium

• Falls

• Functional decline

• Increased dependence

• Accelerated cognitive decline

Unfamiliar environments and routines may worsen stress and confusion.

38. Nursing Concepts: How They Apply

Advocacy

• Balance safety with autonomy

• Report abuse

• Prevent ageism

• Promote access to resources

• Support independence

Cognition

• Know baseline cognition

• Slower processing can be normal

• Acute confusion is not

• Distinguish dementia, delirium, and depression

• Correct sensory deficits

Development

• Middle adulthood: Generativity vs. stagnation

• Older adulthood: Ego integrity vs. despair

• Development continues throughout life

Family

• Assess caregiver burden and role reversal

• Include family strengths/resources

• Refer to community services

Identity

Support identity through:

• Independence

• Self-care

• Decision-making

• Meaningful activities

• Reminiscence

• New roles

Sexuality

Sexual interest and intimacy may continue throughout older adulthood.

39. Highest-Yield Chapter 24 Distinctions

These are the points I would memorize almost word-for-word:

Aging is normal; disease is not.

Slower response ≠ cognitive impairment.

Acute confusion is not normal aging.

Incontinence is not automatically normal aging.

Pain is not automatically normal aging.

Depression is not normal aging.

Dementia = usually chronic and progressive.

Delirium = acute, fluctuating, often caused by another problem, and potentially reversible.

Older age ≠ dependence.

Most older adults live in the community.

Sexuality does not end with aging.

Functional health and the ability to adapt are more meaningful than age alone.

Nursing care should preserve safety, function, independence, and autonomy whenever possible.
