24
Q

Factors Affecting Sensory Function:

A

Developmental Stage
Culture
Stress
Medications and Illness
Lifestyle and Personality
Sensory Alterations

25
Q

Is a lack of culturally assistive, supportive, or facilitative acts

A

Culture Deprivation or Culture Care Deprivation

26
Q

Is generally thought of as a decrease in or lack of meaningful stimuli

A

Sensory Deprivation

27
Q

Responses to Sensory Deprivation:

A

Excessive yawning, drowsiness, sleeping
Decreased attention span, difficulty concentrating, decreased problem-solving ability
Impaired memory
Periodic disorientation, general or nocturnal confusion
Preoccupation with somatic complaints, such as palpitations
Hallucinations or delusions
Crying, annoyance over small matters, depression
Apathy, emotional lability

28
Q

Clients with sensory deprivation are those that:

A

Are confined in a nonstimulating or monotonous environment in the home or healthcare agency
Have impaired vision or hearing
Have mobility restrictions such as quadriplegia or paraplegia with bedrest, traction apparatus
Are unable to process stimuli, like clients who have brain damage or taking medications that affect the central nervous system
Have emotional disorders and withdraw within themselves
Have limited social contact with family and friends

29
Q

Generally occurs when an individual is unable to process or manage the amount or intensity of sensory stimuli

A

Sensory overload

30
Q

3 factors that contribute to sensory overload:

A

Increased quality or quantity of internal stimuli, such as pain, dyspnea, or anxiety
Increased quality or quantity of external stimuli, such as noisy healthcare settings, intrusive diagnostic studies, or contact with many strangers
Inability to disregard stimuli selectively

31
Q

Responses to Sensory Overload:

A

Complaints of fatigue, sleeplessness
Irritability, anxiety, restlessness
Periodic or general disorientation
Reduced problem-solving ability and task performance
Increased muscle tension
Scattered attention and racing thoughts

32
Q

Clients with sensory overload are those that:

A

Have pain or discomfort
Are acutely ill and have been admitted to an acute care facility
Are being closely monitored in an intensive care unit and have intrusive tubes such as IVs, catheters, or nasogastric or endotracheal tubes
Have decreased cognitive ability

33
Q

Is impaired reception, perception, or both of one or more of the senses. This can include things like blindness and deafness.

A

Sensory Deficits

34
Q

How the body responds to the loss of sensory function. Things like using the left ear when there is hearing loss in the right ear.

A

Compensatory behavior

35
Q

Nursing assessment of sensory-perceptual functioning includes six components:

A

Nursing history
Mental status examination
Physical examination
Identification of clients at risk
Client’s environment
Client’s social support network

36
Q

The nurse assesses the client’s current sensory perceptions, usual functioning, sensory deficits, and potential problems

A

Nursing History

37
Q

This includes data on mental status, including level of consciousness, orientation, memory, and attention span

A

Mental Status Examination

38
Q

This assessment determines whether the senses are impaired. This can include testing for vision, hearing, smelling, tasting, feeling, and kinesthetic senses.

A

Physical Examination

39
Q

A nurse should assess this for quality, quantity, and types of stimuli.

A

Client Environment

40
Q

Nonstimulating environments include:

A

Severely restrict physical activity
Limit social contact with family and friends

41
Q

The degree of isolation an individual feels is significantly influenced by the quality and quantity of support from family members and friends.

A

Social Support Network

42
Q

For social support network, a nurse should assess:

A

Who visits and when
If the client lives alone
Any signs indicating social deprivation (withdrawal from contact with others to avoid dependence on others or embarrassment, negative self-image, reports lack of meaningful communication with others, absence of opportunities to discuss fears or concerns that facilitate coping mechanisms)

43
Q

Is the leading cause of blindness in adults older than 65

A

Age-related Macular Degeneration

44
Q

Are opacities of the lens. Development is slow and painless and may be unilateral or bilateral. They are the leading cause of blindness in the world.

A

Cataracts

45
Q

Is associated with optic nerve damage due to an increase in intraocular pressure and leads to vision loss. It is the 2nd most common cause of blindness in the US

A

Glaucoma

46
Q

Is a microvascular disease of the eye, occurring in both type 1 and type 2 diabetes.

A

Diabetic Retinopathy

47
Q

Otherwise known as acute confusion. It has an abrupt onset and a cause, that when treated, reverses the confusion.

A

Delirium

48
Q

Is often called chronic confusion. It has symptoms that are gradual and irreversible

A

Dementia

49
Q

Is considered the golden standard in identifying clients with delirium

A

Confusion Assessment Method

50
Q

Is a screening tool in which family members are interviewed to maximize the detection of delirium in clients

A

Family CAM or FAM-CAM
