Exam 1 - CN (normal aging) Flashcards
age-related changes in body composition
- decreased body mass
- decreased elasticity and flexibility of muscles
- decreased total body water
- increased fat tissue
sarcopenia
decrease in muscle, increase in fat
considerations for changes in body composition
- effects of medications
- changes in diet
- decrease sodium intake
- reduce calorie intake
- increase intake of protein, calcium, and vit D
age-related decrease in kidney function affects
medications metabolized by the body
age-related changes in the cardiovascular system
- heart muscles thicken
- valves enlarge and stiffen
- muscular contraction force decreases
tachy
too fast
myo
muscle
infarct
dead tissue
considerations for changes in the cardiovascular system
- elderly person uses O2 less efficiently
- lowered ability to maintain physical activity for long periods of time
- safer w/ low intensity exercise
age-related changes in gastrointestinal system
- decreased contraction of esophageal muscles
- diminished secretion of digestive juices
- diminished efficiency of small intestine
- decreased contraction of colon
- decreased mass of liver, gallbladder, and pancreas
The gi system decreased in
size, mass, & efficiency
considerations for changes in the GI system
- diet changes - may need to reduce fat and sugar intake
- remain upright during and after meals to aid digestion
- avoid eating late in the evening
age-related changes in the endocrine system
- F experience decreased production of hormones (estrogen & progesterone)
- M & F experience decreased productions of hormones (testosterone, thyroid hormones, growth hormones, insulin)
considerations for changes in the endocrine system
- hormone replacement therapy
age-related changes in respiratory system
- decreased max capacity
- decreased lung elasticity
- vital capacity declines
- cilia reduced
- decreased cough
respiratory physician
pulmonologist
considerations for changes in the respiratory system
- remain active
- pace tasks
- avoid strenuous activities
age-related changes in the CNS
- neuron and glial cell loss
- decreased brain weight by 10%
- accumulation of lipofuscin (fat)
- slower neuronal transmission
- increased reaction times (takes longer to react)
considerations for changes in the CNS
- decrease factors which compound neuronal loss (smoking, alcohol, diet, lifestyle)
- allow more time for responses
- allow more time for decisions
- compensate for extra time requirements
age-related changes in the renal & urinary systems
Kidneys
1. decrease in volume and weight
2. renal functions decreases by up to 50%
Bladder
1. reduced capacity
2. delayed sensation of needing to empty
kidney physician
nephrologist
considerations for changes in the urinary system
- higher sensitivity to alcohol, caffeine, and meds
- urinary incontinence may lead to dehydration
- may avoid social outings for fear of no access to bathrooms
age-related sexual changes
F:
1. decreased secretions in vagina
2. slower response to sexual stimulation
M:
1. decreased force of ejaculation
2. decreased sperm
3. rapid loss of erection
considerations for sexual changes
- changes do not lead to sexual incapacity or decreased desire
- still need privacy to express sexual desires
- avoid teasing older adults or accusing them of being inappropriate
age-related changes in sleep patterns
- sleep stages decrease in duration
- sleep cycles are fewer and shorter
- circadian rhythms change
- poor sleep quality
considerations for changes in sleep patterns
- sleep meds may make it worse
- encourage elderly person to improve sleep hygiene (dark room, decrease caffeine)
- may take naps
age-related changes in musculoskeletal and proprioceptive system
- bone loss
- joint stiffness
- loss of strength & stamina
- decreased ability to orient body in space
considerations for changes in musculoskeletal and proprioceptive system
- take cautious, shuffling steps
- seek external spatial cues and supports
- need to improve balance and strength with general and aerobic exercise
- difficulty climbing stairs
age-related changes in the integumentary system
- hair
- skin
- nails
considerations for changes in the integumentary system
- rec temp levels:
- 68 in winter
- <90 in summer - skin tears and bruises more easily
- ear wax accumulates & may cause hearing loss
age-related changes in vision
- blurred vision
- decreased visual acuity
- decreased contrast sensitivity
- poor adaptation to changes in illumination
- changes in perception of colors
- poor depth perception
considerations for changes in vision
- reduce glare
- increase yellow light
- increase light levels & designate warning markers in hallways, entrances, stairways
- larger print
- use reds & yellows; avoid blues
age-related changes in hearing
- presbycusis
- poor hearing sensitivity/detection
- poor speech understanding
- difficulty understanding speech in noise
presbycusis
age-related hearing loss
considerations for changes in hearing
- reduce competing noises
- use sound-absorbing materials when possible
- speak slowly clearly and with slightly lower pitch
- may feel embarrased
age-related changes in the vestibular system
- loss of sensory cells
- response to linear mvmt may deteriorate
- poor balance function
considerations for changes in the vestibular system
- sensation of spinning for dizziness
- risk of falling
- neg psychological effects
- use compensatory strategies (holding rails, well- lit areas)
age-related changes in the somatosensory system
- touch - loss of sensitivity
- temp - lack of response to extreme temps
- pain - decreased ability to discriminate levels of pain
considerations for changes in the somatosensory system
- burns and other injuries may be more serious
- manipulation of small objects may take additional time (pills, HA + batteries)
- all humans benefit from touch
age-related changes in taste and smell
- taste sensitivity usually decreases after 60
- more olfactory receptors degenerate than replaced
considerations for changes in taste and smell
- unable to detect gas leaks, smoke, pleasant scents, bodily odors
- changes in social patterns during meals and prep
- flavor additives are successful in help adapt (salt substitutions)
age-related changes in swallowing
- decreased cough
- increased risk of aspiration
- changes in oral-pharyngeal mechanism
considerations for changes in swallowing
- take smaller bites
- cut up food well before chewing
- eat sitting upright
- use alternate seasonings rather than salt
age-related changes in cognition
- attention - neg affected by several factors
- intelligence - some effect on fluid IQ
- memory - working memory is affected, but storage capacity remains (gets harder to retrieve)
fluid IQ
innate/biological IQ
cognition considerations
- personalize environment
- create a balance in activities
- encourage to:
-reminisce
- reduce fatigue and stress
- use lists to aid memory
- remain mentally active
HL is associated with
cognitive decline
with normal aging, remember to:
- differentiate normal aging changes from disease
- maintain or increase each person’s activities to prevent deterioration
- preserve each person’s dignity
- observe each person’s privacy
- appreciate each person’s ethnicity, culture, and history
atherosclerosis
hardening of the arteries
