Older Adults
Core Concepts in Gerontological Nursing and Demographics
Definition of Old Age: According to United States demographics and social policy, old age is defined as beginning at the age of years.
Individual Uniqueness: Each adult is considered unique; aging does not manifest identically across individuals.
Aging Population: America is progressively aging, leading to an increase in the older adult population.
Diversity Considerations: Nurses must integrate cultural, ethnic, and racial diversity into their clinical considerations when providing care to older adults.
Myths and Stereotypes of Older Adults: These involve false perceptions regarding physical characteristics, psychosocial traits, and lifestyles. Common examples include viewing older adults as: * Ill, disabled, or unattractive. * Forgetful, confused, rigid, boring, or unfriendly. * Poor or unable to learn and understand new information. * Lacking interest in sex or sexual activities.
Ageism: This term refers to the negative affects of stereotyping based on age.
Nurses' Responsibilities in Combatting Stereotypes: * The provision of respect and dignity. * Encouraging the involvement of the patient in their own care.
Holistic Physiological Changes of Aging
General Survey and Assessment: * Perception of well-being is the primary factor defining quality of life for older adults. * The general survey begins during the initial nurse-patient encounter. * It involves a quick but careful head-to-toe scan for universal aging signs. * Observations should include facial expression, interaction, eye contact, range of motion (ROM), grooming, and communication skills.
Neurological System: * Degeneration of nerve cells and a decrease in neurotransmitters. * Decrease in the rate of nerve impulse conduction. * Voluntary reflexes become slower. * Reduced ability to respond to multiple stimuli simultaneously. * Alterations in both the quality and quantity of sleep.
Head and Neck: * Facial features change due to the loss of subcutaneous fat and skin elasticity. * Vision Changes: * Visual acuity declines. * Presbyopia: A decrease in the ability to accommodate to near and far vision. * Difficulty adjusting to light changes (e.g., moving from light to dark environments). * Yellowing of the lens and altered color perception, particularly difficulty recognizing green, blue, and pastel colors. * Increased sensitivity to glare. * Smaller pupils that react more slowly. * Prevalence of diseases such as cataracts (clouding of the lens), macular degeneration, diabetic retinopathy, and retinal detachment. * Hearing Changes: * Changes are often subtle, and many adults ignore them until prompted by others. * Presbycusis: Age-related hearing loss affecting the ability to hear high-pitched sounds; more prevalent in men than women. * Taste and Smell: * Salivary secretion is reduced. * Taste buds atrophy and lose sensitivity, making it difficult to distinguish between salt, sweet, bitter, and sour. * Loss of smell occurs. * Nutrition becomes a significant challenge due to these sensory losses.
Heart and Vascular System: * Decreased contractile strength of the myocardium. * Slight enlargement of the heart and stiffening of the heart wall. * Changes in heart rate. * Blood pressure (BP) may be abnormally high; hypertension (HTN) is common but is explicitly noted as not a normal part of the aging process. * Heart valves thicken and stiffen. * Lower extremity pulses may be weaker but should remain palpable.
Respiratory System and Thorax: * Lungs: Decreased respiratory muscle strength and lung expansion; the cough is less deep. * Increased susceptibility to pneumonia and other respiratory infections. * Increase in the anteroposterior diameter of the thorax. * Decrease in the total number of alveoli and cilia. * Thorax: Calcification of costal cartilage leads to decreased rib mobility; the chest wall stiffens with less recoil. * Kyphosis: Vertebral changes resulting from osteoporosis, leading to a forward curvature of the spine.
Gastrointestinal (GI) System and Abdomen: * Increase in fatty tissue in the trunk and abdomen, leading to a more protuberant abdomen. * Slowing of peristalsis. * Decreased production of saliva and digestive enzymes. * Delayed gastric emptying leading to food intolerance.
Urinary System: * Prostate: Hypertrophy of the prostate gland leads to urinary retention, frequency, incontinence, and increased Risk of Urinary Tract Infections (UTIs). * Prostate Cancer Statistics: The American Cancer Society estimates that in men will have prostate cancer and in will die from it. * Decreased bladder capacity. * Urinary Incontinence in Women: Stress incontinence (leaking when coughing, sneezing, laughing, or lifting) caused by weakening of perineal and bladder muscles. * Risk factors include age, menopause, Diabetes Mellitus (DM), hysterectomy, stroke, and obesity.
Integumentary System: * Decreased skin turgor, moisture, resilience, and subcutaneous fat. * Thinning of the epithelial layer and shrinking/rigidification of elastic collagen fibers. * Wrinkles reflecting lifelong facial expressions. * Lesions: Presence of age spots (senile lentigo), seborrheic keratoses, cherry angiomas, and premalignant or malignant lesions (Basal Cell Carcinoma, Squamous Cell Carcinoma, Melanoma). * Hair and Nails: Hair thins, grays, and becomes sparse; nail growth slows and nails thicken.
Musculoskeletal System: * Muscle strength diminishes proportionally to the decline in muscle mass. * Bone and muscle mass loss can be mitigated through regular exercise. * Osteoporosis: A significant public health threat; postmenopausal women are at higher risk than men. * Demineralization can be reduced by calcium intake. * Risk factors in men include poor nutrition and decreased mobility.
Reproductive System: * Structural and functional changes caused by hormonal alterations. * Women: Reduced estrogen and progesterone; dryness of vaginal mucosa, irritation, and pain during intercourse; decreased libido. * Men: Erection becomes less firm; ejaculation is less forceful; testosterone levels lessen, leading to decreased libido; no definite cessation of fertility. * Sexual Activity: Desires and thoughts remain; decreased activity is often due to illness, loss of a partner, or decreased socialization. * Breasts: Diminished estrogen leads to firmer breast tissue and decreased muscle mass/tone; gynecomastia (enlarged breasts) can occur in men; both sexes are at risk for breast cancer.
Immune System: * Slower response to stressors and slower healing processes. * Reduced production of B and T lymphocyte cells and antibodies. * Increased production of autoantibodies, leading to increased autoimmune responses. * Decreased core body temperature and decreased response to immunizations.
Functional and Cognitive Assessments
Functional Status: Refers to the capacity and safe performance of Activities of Daily Living (ADLs) and Instrumental Activities of Daily Living (IADLs). * ADL performance serves as a sensitive indicator of health or illness. * Physical Therapy (PT) and Occupational Therapy (OT) are essential resources for comprehensive functional assessment.
Cognitive Changes: * Significant cognitive impairment is not a normal part of aging. Symptoms requiring further assessment include confusion, disorientation, forgetfulness, loss of language/calculation skills, and poor judgment. * Assessment Tools: Mini-Mental State Exam-2 (MMSE-2), Mini-Cog, and the Clock Drawing Test. * Physical cause: Reduction of brain cells and changes in neurotransmitter levels.
Psychosocial Changes and Developmental Tasks
Developmental Adjustments: Aging individuals must adjust to changes in health and physical strength, retirement, fixed or reduced income, death of loved ones, self-acceptance of aging, new living environments, and redefining relationships.
Key Issues: Retirement, social isolation, sexuality, housing and environment, and dealing with death.
Nursing Considerations and Care Settings
Placement Decisions: Nurses assist by answering questions, educating on options, and encouraging facility visits to determine quality. * Resources like the Medicare website (NHcompare) are useful. * Positive Indicators for Centers: Privacy and personal rooms (not hospital-like), Medicare/Medicaid certification, qualified staff with background checks, quality of food/mealtime choices, and encouragement of family involvement.
Acute Care Management: * Prioritize basic needs: comfort, safety, nutrition, hydration, and skin integrity. * Promote independence and dignity by including the patient in their care. * Risks in Acute Care: Delirium, malnutrition, dehydration, Healthcare-Associated Infections (HAIs), urinary incontinence, and falls. * Delirium Management: Encourage family visits, provide memory cues, compensate for sensory deficits, and use reality orientation.
Restorative Care: * Ongoing care for recovery from acute illness or support of chronic conditions. * Goal: Regain or improve prior levels of independence in ADLs and IADLs.
Specific Health Concerns and Preventive Measures
Chronic Conditions: Heart disease, cancer, chronic lung disease, and stroke.
Lifestyle Factors: Smoking, alcohol abuse, nutrition, exercise, and dental problems.
Nutrition: * Influences: Lifelong habits, tradition, culture, preference, religion, chronic illness, and medications. * Recommendations: Increase intake of Vitamin D, , Vitamin E, folate, fiber, and calcium. Increase fluids unless contraindicated. Limit sodium, fat, refined sugar, and alcohol. * Healthcare Setting Strategies: Promote eating with others, ensure food accessibility, ensure patient comfort/hygiene/environment, and consult a dietician.
Falls Prevention: * Statistic: Every minutes, an older adult dies from a fall in the United States. * Intrinsic Risks: History of falls, fear of falling, muscle weakness, impaired vision, postural hypotension, balance issues, medications (sedatives, hypnotics, opioids), and chronic conditions (diabetes, dementia, arthritis). * Extrinsic Risks: Poor lighting, lack of handrails or grab bars, poor stair design, obstacles (cords, throw rugs), and inappropriate footwear.
Polypharmacy: * Concurrent use of multiple medications; affects approximately of older adults. * Advice: Use one Health Care Provider (HCP) to manage all meds. In long-term care, review medications monthly and consider nonpharmacological methods first.
Atypical Disease Presentation and Assessment Strategies
Early Illness Indicators: Changes in mental status, falls, dehydration, decreased appetite, loss of function, dizziness, and incontinence.
Atypical Presentation Examples: UTIs, Pneumonia (PNA), and Myocardial Infarction (MI) may not present with standard symptoms (e.g., lack of fever in infection).
Setting-Specific Presentation: * Hospital: Confusion (look for meds/neurological events), chronic dehydration. * Nursing Home: Undertreatment of pain (use nonverbal cues), drug toxicity, new incontinence. * Ambulatory Care: Reports of fatigue/decreased activity (anemia, thyroid), increased dyspnea (cardiac history), depression signs. * Home Care: High risk for drug-drug or food-drug interactions due to multiple providers.
Psychosocial Health Interventions and Teaching
Elder Mistreatment: Defined as an intentional act or failure to act that causes harm or risk of harm. Includes physical and emotional abuse. * Screening should be done privately without the caregiver. * Mandatory Reporting: Required by law in Kentucky.
Psychosocial Interventions: Therapeutic communication, touch, reality orientation, validation therapy, reminiscence, and body image interventions.
Teaching Strategies: * Assess readiness to learn. * Speak clearly and slowly in a normal tone; allow the patient to read lips. * Present one idea at a time and allow extra processing time. * Minimize environmental distractions and use the Teach-Back method. * For Hearing Deficits: Get their attention first, reduce background noise, speak clearly/loudly, use repeat cycles, and ensure good lighting.
