true
nurses role with older adults
-Empower older adults to lead fulfilling lives despite their illness diagnosis.
- Interventions to manage chronic diseases so older adults can maintain optimal levels of functioning.
- A holistic approach for the maintenance of well-being of older adults (wellness approach).
- Explore patients’ abilities and strengths for optimal health outcome and enhanced wellness.
health disparities
significant differences in regard to rate of disease incidence, prevalence, morbidity, mortality, life expectancy between one population and another
health literacy
- Major determinant of health outcomes and measure of quality of care
- Low health literacy associated with negative outcomes and increase in costs
- National initiatives include identifying and implementing evidence-based approaches to assessment and interventions for health literacy.
Ethnogeriatrics
integrates influence of race, ethnicity and culture on health and well-being of older adults
Older Adults in high risk groups
- Older adults in rural areas
- Homeless older adults
- Lesbian, gay, bisexual and transgendered older adults (LGBT)
- aboriginals
functional consequence theory
- Observable effects of actions, risk factors, and age related changes that influence the quality of life or day to day activities of older adults
- Older adults experience positive or negative functional consequences because of a combination of age-related changes and additional risk factors.
- Nurses can promote wellness in older adults through health promotion interventions and other nursing actions that address the negative functional consequences.
- Nursing interventions result in positive functional consequences, also called wellness outcomes, which enable older people to function at their highest level despite the presence of age-related changes and risk factors.
Negative functional consequences
those that interfere with functioning or quality of life, cause dependency
Positive functional consequences:
those that facilitate the highest level of functioning, least dependency and best quality of life. They are wellness outcomes
functional assessment
Focuses on older adult’s ability to perform activities of daily living that affect survival and quality of life
Functional Consequences Theory vs Functional Assessment
Functional Consequences Theory is broader because it
- Distinguishes age-related changes that increase vulnerability and risk
- Focuses on consequences
- Focuses on assessment of conditions that affect function
- Leads to interventions to address the negative
- Leads to wellness outcomes
age related changes vs risk factors
- Age-related changes cannot be reversed or altered, but it is possible to compensate for their effects so that wellness outcomes are achieved.
- By contrast, risk factors can be modified or eliminated to improve functioning and quality of life for older adults.
age related changes
- Inevitable, progressive and irreversible changes that occur and are independent of extrinsic or pathologic conditions
- On the physiologic level, these changes are typically degenerative.
- Holistic focus: identify age-related changes to improve/adapt to physiologic decline
risk factors
- Conditions that increase vulnerability to negative functional consequences
- Common sources of risk factors include diseases, environment, lifestyle, support systems, psychosocial circumstances, adverse medication effects, and attitudes based on lack of knowledge
- Environmental conditions are risk factors when they interfere with function.
- Environmental conditions are interventions when they enhance function.
theoretical perspectives on aging
Biological Theories of aging
Sociocultural Theories
Psychological Theories
biologic theories
- wear and tear theory
- cross linkage theory
- free radical theory
- genetic theory
- immune theory
wear and tear theory
Body can be likened to a machine that is expected to function well during the period of its warranty, but that will wear out at a fairly predictable time.
cross linkage theory
Biochemical processes create linkages, or connections, between structures that normally are separated. This causes a buildup of collagen-like substances that leads to failure of tissues and organs.
free radical theory
They are waste products of metabolism and they can damage cells. Healthy bodies have protective mechanisms that can remove and repair damaged cells; however, these mechanisms become less effective with increased age and cellular damage becomes cumulative.
genetic theory
emphasizes the role of genes in the development of age-related changes
Immunosenescence/immune theory
Immunosenescence, which is an age-related decline of the immune system, increases the susceptibility of older people to diseases, such as cancer and infections. The immune system may even attack healthy cells, leading to autoimmune conditions, such as rheumatoid arthritis.
biologic theory: nursing
Primary role: Identify and address modifiable factors that lead to diseases, disability, death, as well as health-promoting factors.
sociocultural perspectives on aging
- disengagement theory
- activity theory
- subculture theory
- age stratification theory
- person environment fit theory
disengagement theory
a society and older people engage in a mutually beneficial process of reciprocal withdrawal to maintain social equilibrium
activity theory
older people remain socially and psychologically fit if they remain actively engaged in life
subculture theory
states that old people, as a group, have their own norms, expectations, beliefs and habits; therefore, they have their own subculture
age stratification theory
People pass through society in cohorts that are aging socially, biologically and psychologically. New cohorts are continually being born, and each experiences a unique sense of history
person environment fit theory
considers the interrelationships between personal competence and the environment. (ego strength, motor skills, biologic health, cognitive capacity and sensory–perceptual capacity)
-focuses on interaction between characteristics of the individual and the environment
psychological perspectives on aging
Nurses can use psychological theories to address response to losses, continued emotional development, devote time and energy to life review and self-understanding.
Five categories of basic human needs, ordered from lowest to highest
physiologic needs
safety and security needs
love and belongingness
Self-esteem
Self-actualization
life course theories
address old age within the context of the life cycle
-how early life events affect future decisions and outcomes
personality development theories
identify personality types as predictive forces of successful or unsuccessful aging
psychological theories of successful aging
- Selection, optimization and compensation
- Socioemotional selectivity theory
- Strength and vulnerability integration theory
- gender related theories
Selection, optimization and compensation
According to this theory, older adults select certain goals and tasks while disengaging from other goals; they optimize necessary resources to achieve these goals; and they compensate by establishing new resources to substitute for lowered or lost abilities and skill
Socioemotional selectivity theory
Proposed to explain emotional well-being during older adulthood. Older adults recognize that their time is limited, so they focus on emotional goals rather than on knowledge-seeking goals
Strength and vulnerability integration theory
Experience age-related gains as well as losses in emotion-related processes, and overall older adults maintain a positive level of emotional experience
gender related theories
- Compare and contrast male and female performance data.
- Examine the nature of change in gender roles.
- Study the relationship between gender role differences and social roles and social power.
Faith community nursing
Faith community nurses spend 50% to 100% of their time providing services to older adults, such as health education, referrals, health screenings, personal counselling, spiritual support and health advocacy
geriatric care managers
primary care coordinator who is responsible for implementing immediate and long-term plans as the needs of the older adult change
sources of home care services
-Formal sources (agencies)
- Informal sources (independent caregivers, word-of-mouth network)
- Geriatric care management services
external ear
- pinna and the external auditory canal
- Cerumen is naturally expelled, but age-related changes—such as an increased concentration of keratin, the growth of longer and thicker hair (especially in men), and thinning and drying of the skin lining the canal—can cause it to build up.
- decreased sweat gland activity with age (makes cerumen drier)
middle ear
- tympanic membrane - transmits sound energy
- With increased age, collagenous tissue replaces the elastic tissue, resulting in a thinner and stiffer eardrum.
- the middle ear muscles and ligaments become weaker and stiffer.
inner ear
- Age-related changes of the inner ear include loss of hair cells, reduction of blood supply, degeneration of spiral ganglion cells and loss of neurons in the cochlear nuclei.
- These degenerative changes of the cochlea and other inner ear structures are the primary cause of the age-related hearing impairment.
The auditory nervous system is affected by all the following age-related changes:
- Degenerative changes in the inner ear
- Narrowing of the auditory meatus
- Diminished blood supply and central nervous system changes.
build up of cerumen causes
- Increased concentration of keratin
- Growth of longer and thicker hair (especially in men), and
- Thinning and drying of the skin lining the canal
leading cause of hearing loss
Impacted cerumen/impacted wax
risk factors for hearing loss
Genetic predisposition
Increased age
White race
Recreational or occupational exposure to noise
Smoking of nicotine products
Secondhand smoke
Ototoxic medications
Certain medical conditions (otosclerosis, diabetes, acoustic neuromas)
Ototoxic environmental chemicals
otosclerosis
- A hereditary disease that affects the bones in the middle ear.
- This impacts the normal movement of ossicles and this disrupts the transmission of sound waves to the inner ear.
- Otosclerosis primarily causes a conductive hearing loss, but some sensorineural loss may also occur.
- it is difficult to hear soft and low-pitched sounds; as the hearing loss worsens, the person is likely to experience dizziness, tinnitus or balance problems.
meunière disease
build up of fluid in inner ear
acoustic neuromas
tumor along vestibulocochlear nerve
conductive hearing loss
abnormalities of external and middle ear interfering with sound conduction
sensorineural hearing loss
abnormalities of sensory and neural structures of inner ear, usually age related or noise induced
Hearing acuity for high-frequency tones normally begins to decline when
in early adulthood, and by the age of 30 years for men and 50 years for women, there is some decline in hearing sensitivity at all frequencies
conductive hearing loss
- Characterized by a reduced intensity of sounds and difficulty hearing vowels and low-pitched tones.
- Occurs in one or both ears
- Often there is a history of otosclerosis, perforated eardrum or other ear disease
presbycusis
- Presbycusis is the sensorineural hearing loss associated with an age-related degeneration of the auditory structures.
- Usually occurs in both ears
- loss of ability to hear high-pitched sounds and sibilant consonants.
- words become distorted
- As the hearing loss progresses, explosive consonants, such as b, d, k, p and t, also become distorted.
- Background noise and environmental conditions, compound the effects of sensorineural hearing loss and can interfere with the ability to recognize words
tinnitus
- persistent sensation of ringing, roaring, blowing and buzzing
- Symptom of underlying condition
- Associated with hearing loss, ototoxic medications and Ménière disease
- Exacerbated with caffeine, alcohol or nicotine
Normal Otoscopic Findings in Older Adults
- Small amount of cerumen
- Pinkish-white epithelial lining, no redness or lesions
- Pearl-grey tympanic membrane, which is less translucent than in younger adults
how often should adults with hearing aids get otoscopic exams
every 3-12 months
auditory rehab
services that improve communication for people who are hearing impaired.
Auditory rehabilitation programs provide: counselling, education, amplification aids, communication methods and management of the environment.
presbyopia
- loss of accommodation
- accommodation - It is the ability to focus clearly and quickly on objects at various distances.
- This vision change is caused by degenerative changes in the lens and the ciliary body.
- ex: the need to hold reading materials farther from the eye to focus clearly on the print.
diminished acuity
- normal value is 20/20
- Visual acuity is best around age 30, after which it gradually declines.
- changes in visual acuity can particularly affect night-driving competence.
dark and light adaptation
- The ability to respond to both dim and bright light begins to decline around the age of 20 years and diminishes more markedly after age 60
- older adult requires more time to adapt to dim lighting when moving from a brighter to a darker environment
- older person responds more slowly to lights, such as car or bus headlights, and requires more time to recover from exposure to glare and bright lights
increased glare sensitivity
- Glare is experienced when light is reflected from shiny surfaces, when the light is excessively bright or inappropriately focused, or when bright light originates from several sources at once
- Beginning in the fifth decade, age-related changes increase a person’s sensitivity to glare and the time required to recover from glare.
- these changes can significantly affect the person’s ability to read signs, see objects, drive at night and manoeuvre safely in bright environments.
reduced visual field
- Functionally, the visual field is important when people engage in tasks that require a broad perception of the environment and moving objects.
- Walking in crowded places and driving a vehicle are examples of activities that depend on the field of vision.
diminished depth perception
- Depth perception is the visual skill responsible for locating objects in three-dimensional space, judging differences in the depth of objects and observing relationships among objects in space.
- Older adults experience diminished depth perception, making it more difficult to use objects effectively and manoeuvre safely in the environment.
altered colour vision
- Opacification and yellowing of the lens causes an altered perception of blues, greens and violets.
- darkening of blue objects and a yellowed perception of white light.
diminished critical flicker fusion
- Critical flicker fusion is the point at which an intermittent light source is perceived as a continuous, rather than flashing, light.
- diminished critical flicker fusion causes a flashing light to appear to be continuous and it can interfere with the discernment of emergency vehicles and road construction lights, especially at night.
slower visual information processing
- Age-related changes of the retinal–neural pathway affect the accuracy and efficiency of visual information processing.
- Thus, older adults generally need more time to process visual information, but the effects are minimal or negligible when tasks are familiar.
Factors that interfere with visual wellness
- Lifestyle factors: poor nutrition, cigarette smoking
- Environmental factors: poor lighting, exposure to sunlight, wind, low humidity, warmer environmental temperatures, secondhand smoke
- Chronic conditions: diabetes, hypertension, Alzheimer or Parkinson disease
- Adverse medication effects: estrogen, corticosteroids, anticholinergics, β-blockers, antiparkinson agents
cataracts
- Leading & reversible cause of visual impairment
- Primary cause of avoidable blindness
- the normally transparent lens becomes cloudy, transmission of light to the retina is diminished and vision is impaired
- difficulty performing activities such as reading and night driving
cataracts risk factors
- Advanced age, exposure to sunlight, smoking, diabetes, malnutrition, trauma or radiation to the eye or head, adverse effect of medications (e.g., corticosteroids)
- Cigarette smoking and exposure to sunlight -most modifiable and preventable risk factor
