I. Overview of Aging
A. Demographics
- 49.2 million Americans 65 and older in 2016 (one in seven, 15.2%); expected to double to 98 million by 2060
- Fastest growth in those 85 and older (6.4 million in 2016 to 14.6 million by 2040)
- Life expectancy 78.6 years (2016); women live about 5 years longer
- Hispanic older adult population growing fastest
B. Health status
- Most have at least one chronic illness; many have several
- Leading causes of death: heart disease and cancer; unintentional injuries now third
- Alzheimer’s deaths rising, expected to quadruple by 2050
- 78% rate health good or better
- Activity limitation declined from 49% (1992) to 44% (2013)
C. Gerontologic nursing
- Interdisciplinary approach; comprehensive geriatric assessment
- Goals: promote and maintain functional status, help older adults use strengths for optimal independence
- Aging is not synonymous with disease; highly individualized
- Functional assessment is the common framework
- Miller’s Functional Consequences Theory: distinguish normal irreversible age-related changes from modifiable risk factors (for example glare sensitivity from normal aging vs cataracts) and design interventions accordingly
II. Physical Aspects of Aging (Table 8-1)
- Intrinsic aging: genetically programmed, universal
- Cells accumulate lipofuscin; elastin and collagen degrade (stiffer connective tissue); more anemia
- Reduced tactile sensation and ability to sense pressure, pain, temperature
A. Cardiovascular
- Heart disease is the leading cause of death in older adults
- Myocardial hypertrophy, valve fibrosis and calcification, fewer pacemaker cells, stiffer arteries leads to reduced stroke volume, increased resistance, hypertension
- Decreased cardiac output, slower heart rate recovery; fatigue with activity
- Atypical presentation: dyspnea, neurologic symptoms, confusion, fatigue, nausea, syncope; burning or sharp upper body pain instead of substernal pain; absence of chest pain does not rule out heart disease
- Orthostatic and postprandial hypotension: check BP in two positions; rise slowly, avoid straining, 5-6 small meals a day, avoid hot showers and whirlpools
- Optimal BP under 130/80; BMI under 25
B. Respiratory
- Increased residual volume; decreased muscle strength, vital capacity, gas exchange, cough efficiency
- Aerobic capacity declines about 10% per decade after the mid-20s
- Infection may present as fatigue, lethargy, anorexia, dehydration, mental status change instead of cough and fever
- Older adults smoke at about 20%; e-cigarettes are not effective cessation aids
- Exercise, fluids, pneumococcal vaccine at 65, yearly influenza vaccine, avoid sick people; cough and deep breathe postop (atelectasis risk)
C. Integumentary
- Thinner dermis, less subcutaneous fat, fewer elastic fibers, less vasodilation leads to poor heat conservation, reduced fever response, hypo- and hyperthermia risk
- Dry, fragile skin; bruises and burns easily
- Limit sun to 10-15 minutes daily for vitamin D; SPF 15 or higher; shower rather than hot tub bath; lotions with petrolatum or mineral oil; report skin changes
D. Reproductive
- Older adults value sexual activity; decline mostly from loss of partner (women) or health problems, ED, medications (men)
- Women: thinner, shorter, less elastic vagina; less lubrication; painful intercourse, bleeding; water-soluble lubricant, possibly vaginal estrogen
- Men: testosterone declines from about 50; sperm possible to 90; ED more often from obesity, smoking, CVD, diabetes, medications (vasodilators, antihypertensives, TCAs)
- Slower arousal and response in both; desire remains; refer for sexual dysfunction
E. Musculoskeletal
- Bone density loss, muscle mass loss, joint degeneration; height loss, kyphosis, fractures
- Degenerative joint disease in most adults over 70; osteoporosis is preventable
- “Use it or lose it”: aerobic, resistance, flexibility, balance exercise; weight-bearing exercise 3 times a week; bone density screening; calcium and vitamin D; get hospitalized patients out of bed early
F. Genitourinary
- Nephron loss (significant around 90); one third show no renal decline
- Decreased GFR, concentrating ability, acid-base recovery; drug accumulation risk
- Urinary incontinence: women 2:1 until 80, then equal; not normal aging; mortality up to 44% in long-term care residents
- BPH causes retention and overflow incontinence
- More UTIs; adequate fluids reduce UTIs and incontinence
- Limit evening fluids; avoid caffeine, alcohol, artificial sweeteners; void regularly and completely; pelvic floor exercises for women
G. Gastrointestinal
- Decreased thirst, smell, taste; one third have dry mouth (from medications and disease, not aging)
- Delayed gastric emptying, early satiety; reduced absorption of iron, calcium, B12, vitamin D
- More gallstones
- Dysphagia increases with age; complication of stroke and Parkinson’s; aspiration may occur without coughing or choking
- Constipation from low fiber, laxative overuse, medications, inactivity, low fluid, high fat, ignoring urge; can cause impaction with diarrhea around it
- Brush, floss, dental care; small frequent high-fiber low-fat meals; sit up during and after eating; avoid laxatives and antacids
H. Nutrition
- Fewer calories needed but more nutrient-dense diet
- Need more sugar to taste sweetness; apathy, depression, loneliness, poverty, poor oral health reduce intake
- MyPlate for Older Adults (Fig. 8-2): fruits and vegetables, whole grains, low-fat dairy, varied protein, healthy oils, herbs and spices instead of salt, plenty of fluids
- Calcium 1200 mg/day for women over 50 and men over 70; vitamin D 600 IU to age 70, 800 IU after 70
- Hospitalized older adults, especially with dementia, are at risk for malnutrition; unintentional weight loss needs evaluation
I. Sleep
- Up to 50% at home and 65% in nursing homes report sleep problems
- Causes: sleep apnea, restless legs, nocturia, pain, HF, incontinence, BPH, depression, dementia, environment
- Consequences: cognitive decline, falls, fatigue, poor quality of life
- Sleep hygiene: bed only for sleep and sex, consistent routine, limit naps, one alcoholic drink a day maximum, no caffeine or nicotine after noon, limit evening fluids, daytime activity in bright light; lavender aromatherapy may help
J. Nervous system
- Small loss of brain mass; fewer neurotransmitters; slower nerve conduction - slower reactions and learning
- Autonomic changes cause orthostatic hypotension; gait and balance changes
- Advise more time to respond, move deliberately; adequate B12 (especially vegetarians)
- Slowed reaction leads to falls and driving errors; driving evaluation by OT and neuropsychologist if unsafe
- Sudden confusion may be the first sign of infection or physical change (pneumonia, UTI, drug interaction, dehydration)
- Increased vulnerability to delirium with illness, anesthesia, room changes
K. Sensory
- Sensory deprivation (lack of or inability to interpret stimuli) can cause boredom, confusion, irritability, disorientation, anxiety and mimic cognitive decline; provide meaningful stimulation (colors, textures, music, touch)
- Vision: presbyopia (fifth decade), yellowed cloudy lens scatters light and causes glare, poor blue-green distinction, slow pupil adjustment, need brighter light; nightlights, avoid glare and night driving, large print, contrasting colors
- Age-related macular degeneration: leading cause of vision loss over 65; affects central vision, not peripheral; risk factors sunlight, smoking, heredity, fair skin, blue eyes; sunglasses, hats, stop smoking; laser photocoagulation and photodynamic therapy
- Hearing: presbycusis - high-frequency loss (f, s, th, ch, sh, b, t, p sound alike); may be mistaken for confusion; check for wax; hearing aids underused in long-term care; reduce background noise, face the person, speak clearly in a low pitch, rephrase
- Taste and smell: sweet especially dulled; smell loss greater than taste; may not detect spoiled food or gas; use lemon, herbs, spices instead of salt
III. Psychosocial Aspects
- Successful aging: adapting to losses with resiliency and coping
- Ageism and stereotypes; older adults may internalize them
- Retirement planning: income, new routines, new friends, varied leisure
- Coping patterns stay consistent through life; common stressors include functional decline, chronic illness, loss of income and roles, death of loved ones
- High coping self-efficacy associated with 92% lower odds of frailty (Chart 8-2)
A. Living arrangements
- 93% live in the community; about 2.3% in nursing homes; 76% own their homes; 28% live alone (mostly widowed women)
- 70% of men over 65 married vs 40% of women
- Most prefer to stay home (“age in place”); home modifications and support services help
- Living with adult children: rewarding but potentially stressful; plan ahead before crisis; include the older adult in decisions
- Continuing care retirement communities (CCRCs): independent, assisted, and skilled care on one campus; large down payment
- Assisted living: minimal supervision, medication help, ADL assistance, meals, laundry; mostly out-of-pocket
- Long-term care: percentage of older adults in nursing homes fell from 5.4% (1985) to 2.3% (2018)
- Medicare covers short-term skilled nursing (often 30-90 days) after hospitalization when therapy shows continued improvement; long-term custodial care is mostly out-of-pocket until resources are exhausted, then Medicaid; family members are not responsible for nursing home costs
- Subacute units in skilled facilities can avoid hospital transfers
B. Role of the family
- Spouse usually primary caregiver, then adult child
- Myths of alienation and abandonment are false; families remain the main support
- Informal caregivers gave 18.5 billion hours of unpaid care in 2018
- Caregiving increases risk of psychiatric and physical illness; effective interventions: psychoeducation and skill building, CBT, combined approaches; web-based programs fit busy caregivers
IV. Cognitive Aspects
- Cognition affected by sensory loss, health, environment, sleep, psychosocial factors
- Temporary cognitive changes (delirium) common with hospitalization or facility admission
- Mini-Mental State Examination (MMSE) screens cognition (orientation, naming, reading)
- Healthy diet, 30 minutes of daily activity, adequate sleep support cognition
- Fluid intelligence (flexible thinking, problem solving) declines; crystallized intelligence (education, experience, verbal skills) remains intact
- Higher education, good senses, nutrition, complex jobs preserve learning
Teaching strategies (Chart 8-4):
- Mnemonics; link new to familiar information; visual and auditory cues
- Glasses and hearing aids on; glare-free light; quiet room
- Short-term goals set with learner; prioritize key information; short sessions paced to endurance
- Encourage verbal participation; reinforce success positively
V. Pharmacologic Aspects
- Older adults use the most medications; adverse reactions common (interactions, wrong doses, polypharmacy)
- Medications affect nutrition: antacids cause thiamine deficiency; laxatives reduce absorption; antibiotics and phenytoin reduce folic acid use; phenothiazines, estrogens, corticosteroids increase appetite and weight
- St. John’s wort decreases warfarin effect
- AGS Beers Criteria: lists potentially inappropriate medications; updated every 4 years
Altered pharmacokinetics (Table 8-2):
- Absorption: less gastric acid, slower motility - rate may be delayed (vitamins, calcium)
- Distribution: less plasma protein leads to more free drug for highly protein-bound drugs (warfarin, sulfonylureas, barbiturates, calcium channel blockers, furosemide, NSAIDs, phenytoin); more body fat stores fat-soluble drugs longer (diazepam, barbiturates, lidocaine, phenothiazines, morphine); less body water and lean mass give higher peaks
- Metabolism: smaller liver, less blood flow leads to prolonged action and toxicity for liver-metabolized drugs
- Excretion: less renal flow and fewer nephrons leads to accumulation (aminoglycosides, cimetidine, digoxin, lithium, procainamide)
Nursing implications:
- “Start low and go slow”; keep regimens simple; reconcile medications at discharge
- Thorough history including alcohol, recreational drugs, OTC, herbals; have patient bring all medications (“brown bag”)
- Assess understanding, health literacy, beliefs about each medication
- Nonadherence causes: number and complexity of drugs, hard-to-open containers, poor teaching, cost, side effects, vision and hearing problems
Adherence strategies (Chart 8-5):
- Assess self-management and psychomotor skills
- Discard old medications; non-childproof caps if no children in home
- Report OTC, herbal, alcohol, recreational drug use; carry a current medication list
- Explain purpose, side effects, dose of each drug; written schedule
- Involve a reliable family member if competence is doubtful
- Use one pharmacy; multi-day pill organizer
VI. Mental Health Problems
- Severe mood swings, uncontrolled laughing or crying, cognitive change, excessive forgetfulness are not normal aging; often treatable
A. Depression
- Most common mood disorder of old age; 15-25% in community, up to 25% in long-term care
- Often follows loss, chronic illness, pain, medication interaction, or undiagnosed illness
- Subtle signs: fatigue, poor memory and concentration, worthlessness, sleep and appetite changes, restlessness, suicidal ideation
- Increased suicide risk; assess routinely
- May be confused with dementia (cognitive problems from apathy, not brain decline)
- Geriatric Depression Scale (Chart 8-6): 30 yes/no items; normal 5 plus or minus 4; mildly depressed 15 plus or minus 6; very depressed 23 plus or minus 5
- Treatment: review and change contributing medications; treat underlying conditions; mild - exercise, bright light, social contact, cognitive and reminiscence therapy; major - antidepressants plus psychotherapy (bupropion, venlafaxine, mirtazapine, SSRIs such as paroxetine; TCAs for some); ECT if drugs fail or are risky
- Antidepressants have anticholinergic, cardiac, orthostatic effects - monitor for falls; may take longer than the usual 4-6 weeks to work; change positions slowly, stay hydrated
B. Substance use disorder
- 7-14% of adults 65 and older report alcohol abuse, dependence, or binge drinking; about 50% drink regularly
- Dangerous because of renal and liver changes and drug interactions; often hidden and denied; screen at routine exams
C. Delirium
- Causes: illness, surgery, medication or alcohol toxicity, dehydration, fecal impaction, malnutrition, infection, head trauma, sensory deprivation or overload
- Older adults especially vulnerable (low reserve, many medications)
- Confusion Assessment Method (CAM, Chart 8-7): acute onset, inattention, disorganized thinking, altered LOC, disorientation, memory impairment, perceptual disturbances, psychomotor agitation or retardation, altered sleep-wake cycle
- Delirium is a medical emergency; report immediately; untreated can cause permanent brain damage or death
D. Alzheimer’s disease (AD)
- Sixth leading cause of death in US (fifth over 65); progressive, irreversible, insidious
- Affects up to half of those 85 and older but is not normal aging; 13.8 million Americans expected by 2050
- Causes: age (greatest risk), genetics, neurotransmitter changes, vascular abnormalities, stress hormones, circadian changes, head trauma, seizures
- Familial (early-onset) under 2% of cases; sporadic late-onset most common
- Pathophysiology: neurofibrillary tangles and neuritic (amyloid) plaques in the cerebral cortex; decreased acetylcholine (memory)
- Early: forgetfulness, subtle memory loss, still independent
- Middle: cannot recognize familiar faces and places, gets lost, repeats questions, word-finding difficulty, concrete thinking, impulsive behavior, trouble with appliances and money; reasoning and reality orientation increase anxiety
- Personality changes: depression, suspicion, paranoia, hostility, combativeness
- Late: nonsense speech, agitation, night wandering, dysphagia, incontinence, total care; death from pneumonia, malnutrition, dehydration
- Diagnosis: definitive only at autopsy; diagnosis of exclusion - rule out depression, delirium, substance abuse, drug toxicity; history and exam; CBC, chemistry, B12, thyroid; EEG, CT, MRI, CSF; GDS and MMSE
- Treatment: cholinesterase inhibitors (donepezil, rivastigmine) slow progression; improvement may occur within 6-12 months; music therapy and behavioral approaches for agitation; drugs only if needed
Nursing management of AD:
- Cognitive support: calm, predictable environment; routine; quiet manner, simple explanations; clocks, calendars, color-coded doors; active participation
- Safety: remove hazards, handrails, lighting, nightlights (sundowning); no driving; supervised smoking; secure doors; ID bracelet; in hospital use distraction or place near nurses’ station; avoid restraints (increase agitation and injury)
- Self-care: break tasks into short steps; OT for adaptive equipment; allow choices; maintain dignity
- Anxiety and agitation: emotional support; familiar, quiet environment; catastrophic reaction (screaming, crying, abuse from overstimulation) - stay calm, do not force the activity, postpone it; music, stroking, rocking, distraction; learn the patient’s triggers
- Communication: unhurried, reduce noise, clear simple sentences, lists early, pointing and nonverbal later, touch conveys security
- Socialization and intimacy: visits, calls, simple activities, pets, plants; intimacy needs continue
- Nutrition: calm simple meals, familiar foods, cueing, small pieces, thickened liquids, check food temperature, adaptive utensils, finger foods, apron rather than bib; eventually needs feeding
- Activity and rest: look for unmet needs behind wandering and sleep problems; daytime exercise, limit naps; music, warm milk, back rub at night
- Family: provide 83% of home care; face hard decisions (driving, finances); caregiver guilt, depression; web-based support; report suspected abuse or neglect to adult protective services (nurse reports, does not need to prove); Alzheimer’s Association, support groups, respite and adult day care
E. Vascular dementia
- Second most common dementia; stepwise decline; multi-infarct dementia most common form
- Risk factors same as CVD (hypertension, cholesterol, smoking, diabetes); controlling them may slow decline
VII. Additional Health Issues
A. Geriatric syndromes
- Multifactorial problems: pressure injuries, poor nutrition, falls, functional decline, urinary and fecal incontinence, delirium, sleep disturbance
- Often acute onset; symptoms may appear in another system first (confusion from UTI, dehydration, MI)
- Geriatric triad: cognitive change, falls, incontinence
B. Impaired mobility
- Causes: stroke, Parkinson’s, diabetic neuropathy, CVD, osteoarthritis, osteoporosis, sensory deficits
- Minimize bed rest (rapid deconditioning); active and passive ROM; frequent position changes
C. Dizziness
- Distinguish true dizziness, vertigo (spinning), near-syncope, disequilibrium
- Causes from ear wax to brain stem or vestibular dysfunction; even minor causes lead to falls
D. Falls
- Unintentional injury is the third leading cause of death in older adults; falls are the most common cause of nonfatal injuries and admissions
- 20-30% of fallers have moderate to serious injury; 1 in 5 falls causes serious injury
- Women injured more; men more likely to die from falls
- 50% of those who cannot get up after a fall and break a hip do not regain prior function
- Causes: extrinsic (lighting, environment) and intrinsic (illness, neuro changes, sensory loss); mobility problems, medications, foot problems, unsafe shoes, orthostatic hypotension, vision, tripping hazards; polypharmacy and alcohol
- Fear of falling and lost confidence follow
- Prevention: small lamps, indirect light, sheer curtains, dull surfaces, nightlights; contrasting colors on stair edges; grab bars at tub, shower, toilet; avoid loose clothing, poor shoes, scatter rugs, clutter, pets underfoot; keep furniture in familiar places
- Quality and Safety Nursing Alert: physical restraints (lap belts, geri-chairs, side rails, vests) and chemical restraints cause many of the injuries they are meant to prevent
E. Urinary incontinence
- Acute or chronic; often unreported unless asked
- Transient causes “DRIP”: delirium and dehydration; restricted mobility; inflammation, infection, impaction; pharmaceuticals and polyuria
- Behavioral approaches can restore continence
- Anticholinergics for urge incontinence often inappropriate (dry mouth, slowed GI, confusion) per Beers criteria
- Detrusor hyperactivity with impaired contractility: no warning, small void then large leak after leaving bathroom; common with dementia; prompted timed voiding, possibly intermittent catheterization; do not show disapproval
F. Infection
- Blunted cell-mediated and humoral immunity; pneumonia, UTI, GI, skin infections common
- Annual influenza vaccine in autumn (high-dose trivalent gives better protection); pneumococcal vaccine; can give both at the same time in separate sites
- Health care workers should be vaccinated
- HIV/AIDS affects older adults too
G. Atypical responses
- Reduced pain perception; MI may present as confusion without chest pain; acute abdomen may lack pain
- Baseline temperature about 1 F lower; 37.8 C (100 F) with systemic symptoms may signal infection; 38.3 C (101 F) almost certainly serious infection; rarely over 39.5 C (103 F); blunted fever means poorer prognosis
- Watch for confusion, increased respirations, tachycardia, skin color change
H. Emotional and systemic responses
- Hospitalization threatens well-being; high risk of delirium, anxiety, fear of being a burden
- Encourage autonomy, independent decisions, early mobilization; positive confident demeanor
- Little organ reserve; illness quickly jeopardizes homeostasis - monitor all systems
I. Elder neglect and abuse
- Neglect is most common; also physical, psychological, sexual, abandonment, financial exploitation
- Underreported; professionals often not trained to recognize it
- Community risk factors for physical and emotional abuse: separated or divorced, low income, functional impairment, younger age
- Ask about abuse privately during the history; most states require nurses to report suspected abuse
- Prevent when caregiver strain is evident: psychologist, social worker, chaplain; support groups, respite, Area Agencies on Aging
J. Social services and costs
- Programs: Medicare, Medicaid, Older Americans Act, SSI, Social Security, Section 202 housing, Title XX
- Area Agencies on Aging (AAAs): needs assessment, referral, case management, transportation, homemaker services, day care, meals, legal services, respite, senior centers
- Older adults are about 15% of population but 38% of health care costs, especially last year of life
- Medicare federal; Medicaid state-run (varies); out-of-pocket costs are 28% of income for poor and near-poor older adults
- Hospice: life expectancy 6 months or less, comfort and preparation for death; palliative care: any stage of serious illness, need not be incurable
K. Aging with a disability
- Higher rates of secondary conditions (for example spinal cord injury)
- Aging parents of adults with intellectual or developmental disabilities need transition support
- Interface and Biopsychosocial models support nurses as advocates
L. Ethical and legal issues
- Encourage advance directives before incapacity
- Advance directive: living will (instructions) and/or durable power of attorney for health care (proxy); signed by person and two witnesses; copy to provider and chart; can request full treatment, not only withholding
- Cultural views may see advance directives as denial of care; focus on the patient’s wishes, not the family’s
- If no directive and patient seems incapable: court competency hearing; judge appoints a guardian
- Mild dementia may still allow some decisions (for example naming a proxy)
- Patient Self-Determination Act (1990): hospitals must educate about advance directives at admission and document it
- Ethical dilemma (Chart 8-8): voluntarily stopping eating and drinking (VSED) can only be chosen by a patient with capacity, not by a surrogate; a VSED decision stated in an advance directive remains binding if capacity is lost
High-Yield Numbers
- One in seven Americans is 65 or older; 98 million by 2060; 85 and older growing fastest
- Calcium 1200 mg (women over 50, men over 70); vitamin D 600 IU to 70, 800 IU after 70
- BP goal under 130/80; BMI under 25

- Urinary incontinence women:men 2:1 until 80; mortality up to 44% in long-term care
- Depression 15-25% community, up to 25% long-term care
- GDS: normal 5 plus or minus 4, mild 15 plus or minus 6, severe 23 plus or minus 5
- Antidepressants: may take longer than 4-6 weeks in older adults
- Fever: 100 F with symptoms suggests infection; 101 F serious; rarely over 103 F
- Falls: 20-30% cause moderate-serious injury; 50% with hip fracture after unassisted fall do not regain function
- Nursing home residence 2.3%; 93% live in community; 28% live alone
- Medicare skilled nursing 30-90 days with continued improvement
- Family provides 83% of AD home care
- Beers Criteria updated every 4 years
- Hospice: prognosis 6 months or less
Priority Nursing Actions and Red Flags
- Sudden confusion: treat as delirium (medical emergency) - look for infection, dehydration, drug toxicity, impaction
- MI and infection may present atypically (confusion, fatigue, no chest pain, low-grade or no fever)
- Check orthostatic BP; teach to rise slowly
- Avoid restraints (physical and chemical)
- Fall prevention: lighting, grab bars, footwear, remove rugs, review medications
- Review medications against Beers Criteria; start low, go slow; reconcile at discharge
- Screen for depression and suicide risk; GDS
- Screen for alcohol misuse
- Ask about abuse privately; report suspected abuse
- Dysphagia: aspiration may be silent
- Encourage annual influenza and pneumococcal vaccines
- Encourage advance directives
