Study Notes

Sensory System

The five senses include sight, hearing, taste, smell, and touch
Taste receptors are located in taste buds on the tongue
Smell receptors are located in the nose
Touch receptors are found in the dermis, especially on lips, toes, and fingertips

Hearing and Vision Disorders

Hearing and vision are important for communication, learning, moving, safety, and balance
Common causes of hearing and vision loss include birth defects, accidents, diseases, and aging
Many individuals experience some degree of hearing or vision loss

Tinnitus

Tinnitus is the perception of noise, ringing, or buzzing in the ears
It is a symptom, not a condition itself
Potential causes include age-related hearing loss, ear injury, or circulatory system disorders
It is usually not serious, but can worsen with age
Treatment can improve tinnitus for many people

Meniere's Disease

Meniere's disease is a disorder of the inner ear, potentially causing vertigo and hearing loss.
Fluid buildup in the inner ear is a contributing factor
Typically affects one ear
Symptoms include vertigo (dizziness), tinnitus, hearing loss, and pain/pressure in the affected ear
Severe dizziness can cause nausea and vomiting
Falls are a major concern; safety is needed during vertigo episodes

Presbycusis

Gradual hearing loss associated with aging
Typically begins after age 50
Currently, there is no cure
Hearing aids and speech reading (lip reading) can be beneficial

Effects of Hearing Impairment

Hearing loss can impact physical, emotional, social, intellectual, and spiritual health
Difficulty with hearing can lead to challenges in speech
Slurred speech, mispronounced words, monotone speech, or difficulty with understanding can develop from hearing loss.
Behavior changes, including speaking too loudly, leaning toward the speaker, or cupping the unaffected ear, might indicate hearing problems

Hearing Aids

Hearing aids are electronic devices placed inside or behind the ear that enhance sound
They increase the volume of sounds but don't correct or cure hearing loss
For troubleshooting, check the device's on/off switch, ensure battery placement is correct, and replace batteries as needed.

Care of Hearing Aids

Handle hearing aids with care due to their expense
Inspect for damage, cracks, or clogs
Correctly insert the hearing aid to avoid causing it to fall out; correctly applying the aid is important
Keep hearing aids in a dry environment and avoid getting them wet
Do not use hearing aids when showering.
Report any missing or damaged aids

Caring for Clients with Hearing Impairment

Some clients wear hearing aids and others do not
Learning sign language may be beneficial for some clients
Encouraging client socialization can prevent isolation
Safety concerns are increased for clients with hearing loss; ensuring safety at all times is essential

Eye Disorders and Vision Impairment

Vision problems can range from mild vision loss to complete blindness
Problems with vision can either occur suddenly or gradually (over time)
One or both eyes can be affected by vision loss
A person is legally blind if their vision at 6 meters (20 feet) is comparable to a person with normal vision at 60 meters (200 feet).
Conjunctivitis (pink eye) is a highly contagious inflammation of the eye's membrane.

Diabetic Retinopathy

Diabetic retinopathy is a complication of diabetes that damages tiny blood vessels in the retina.
This condition usually affects both eyes.
Anyone with diabetes is at risk of developing diabetic retinopathy
Blood leakage from damaged vessels can lead to scar tissue formation which pulls the retina away from its position, potentially causing vision loss

AMD (or ARMD) is a condition that causes central vision blurriness.
It affects the macula, a crucial part of the retina
It's typically a progressive condition with gradual onset.
AMD is a common cause of vision loss in older adults, and is one of the leading causes of blindness in people over 55.
There is currently no known cure for AMD

Glaucoma

Glaucoma is an eye disease caused by pressure buildup within the eye, potentially damaging the optic nerve
Vision loss, sometimes leading to blindness, is a possible outcome.
Glaucoma usually has a gradual onset, although sometimes a sudden onset occurs
Vision loss often affects the peripheral (side) vision first, and can progress to tunnel vision.
Medications and/or surgery are often used to control glaucoma and prevent further damage.

Cataracts

Cataracts are clouding of the lens within the eye impacting how light enters the eye; this causes blurred vision
They can affect one or both eyes
Symptoms may include sensitivity to light, cloudy vision, and blurry vision.
Surgery is typically the only treatment for cataracts

Presbyopia

Presbyopia is a gradual inability to focus on close objects.
It is common in older people due to aging process
Usually starts after age 40
Corrective lenses, such as eyeglasses or contact lenses, can effectively treat presbyopia

Effects of Vision Impairment

Vision loss impacts various aspects of an individual's life, such as social interactions, independent living, and daily activities.
Individuals with vision loss may learn alternative ways to perform daily tasks, adapt techniques for reading, and develop new coping strategies.
Guide dogs and white canes with red tips widely aid in vision impairment. Resources like the Canadian National Institute for the Blind provide support and resources.

Aids for Vision Problems

Eyeglasses can correct vision impairment
Plastic lenses can easily be scratched, thus requiring special cleaning, whereas hard/soft contact lenses require proper cleaning, soaking, and appropriate usage

Aids for Reading

Braille is a tactile reading and writing system utilizing raised dots
Communication aids include large-print materials like clocks and cards
Medical devices, like talking prescription devices, can support individuals with vision loss

Caring for Clients With Vision Loss

Enhance physical senses like hearing, touch, taste, and smell to adapt to vision loss; this may lead to increased sensitivity to sounds.
Clients need to be alert to their presence and surroundings
Direct clients toward objects and/or obstacles ahead.
Provide information about the environment to prevent injuries, and keep the environment free of clutter
Refer to specific guidelines/resources, as needed

Dying Client's Physical Needs

Vision loss, speech difficulties, and hearing loss are common signs of physical decline in dying clients; these changes affect communication and interaction.
Body temperature (skin coolness, pallor, mottling) are physical changes to monitor during end-of-life care
Always assume client can hear; prioritize the client's needs.
Maintain comfort, provide necessary pain management, and ensure comfort with positioning
