Significant distress for patient and family
Delirium
50
is a medical emergency
Cognitive changes in older people often labeled as confusion by nurses and physicians; frequently accepted as part of normal aging

meds
invasive equipment
metabolic disturbances
dehydration
alc or drug abuse
sensory impair
unrelieved pain
surgery
hip fracture

Managing risk factors
HELP program
Deliberate interventions to prevent delirium
Pharmacological treatment- Careful!!!
Communication
54
what are the Delirium preventions? (box 29.9)
know the persons past
look at nonverbal signs, such as tone of voice, facial expressions, and gestures
speak slowly
be cam and patient
face the person and keep eye contact; get to the level of the person rather than standing over him/her
explain all actions
smile
use simple, familiar words
allow adequate time for response
repeat if needed
tell the person what you want him/her to do rather than what you so not want him/her to do
give one-step directions; use gestures and demonstrations to augment words
reassure persons safety
keep caregivers consistent
assume that comm and behavior are meaningful and an attempt to tell us something or express needs
do not assume that the person is unable to understand or experiencing cog impairment
55
Irreversible state that progresses over years in decline
dementia

Affects about 5% of persons with AD
Results from genetic mutations of three genes
Genetic testing available for at risk individuals
63
what is late onset AD?
Late onset (after age 60)
Does not run in families
Probable combination of lifestyle, environmental factors, and genetic mutation
64
What are the alz disease diagnosis/stages?
preclinical
mild cog impair

65
what is preclinical AD?
Early cognitive decline before overt symptoms are present 5-20 yrs
66
what is mild cognitive impairment AD?
Amnestic MCI
Multiple domain MCI
Single non-memory MCI
Approximately 12% of persons over age 70 have MCI and are 3-4 times more likely to develop AD
67
what is Alzheimer’s Dementia—most advanced stage?
multiple deficits present
68
what is the treatment of AD?
Regular monitoring of disease progression and response to therapy
Caregivers also need ongoing education about the disease as well as assessment of own coping mechanisms and self-care behaviors
69
What is the pharm treatment of AD?
Cholinesterase inhibitors (CI)
Directed toward symptom management
Does not affect neuronal decline
70
Why is it Important to assess and treat for depression in AD?
If present will cause excess disability
71
What is the AD health promotion?
person-centered care
How to enhance well-being and quality of life
Treating the person, not the disease
Establish connections and sense of security
Special skills and attitudes necessary to nurse the person with dementia
Maintain function and prevent excess disability
PLST (Progressively Lowered Stress Threshold) model
Care is structured to decrease stressors and provide a safe and predictable environment
NDDH (Need-Driven Dementia-Compromised Behavior) model
Care is structured to enhance understanding of behavior as expression of need
Care is optimized by manipulating factors that precipitate behavior
72
What is the assessment side of health promo in AD?
View all behavior as meaningful and expression of needs
Focus on reasons for Behavioral & Psychological Symptoms of Dementia
Remember: You must enter the patient’s reality and not attempt to reorient them to actual reality. They cannot be reoriented due to the deterioration within the brain.
73
what are the general interventions for dementia?
Address Safety
Structure daily living to maximize abilities
Monitor general health
Support advance care planning and directives
Educate and support caregivers
74
what are the pharm treatment interventions for dementia?
If patient is danger to self or others
Non-pharmacological interventions not effective
Risk/benefit of medication has been considered
75
how do you provide care for ADLs in dementia?
Perceptual disturbances and misinterpretation of reality can cause much distress for patient and caregiver during this time
Can be perceived as an attack by a stranger
See the world from the patient’s perspective
Alternative bathing methods as tolerated
76
What is the nursing intervention care for AD?
Wandering
Difficult problem to manage
May be a soothing mechanism
Not well understood
Risk
Falls, elopement, injury, and death
Things to do
Music, exercise, refreshments, social interaction
Camouflage doorways, enclosed areas for walking, electronic bracelets,
60% will wander and become lost at some point…
Wandering interventions and Avoiding getting lost
77
What is the caregiving for persons with dementia?
almost 2/3 of unpaid caregivers for Americans with AD are women
70% with dementia live at home
78
what do you need to know about caregivers?

Fewer health-promoting behaviors
Higher rates of depression and anxiety
Higher morbidity and mortality
Sleep disturbances
Higher number of illness-related symptoms
79
what do you need to know about caregiving stress?
Grief over multiple losses that occur
Physical demands and duration of caregiving
Exacerbated when care recipient demonstrates behavioral issues and impairments in ADL’s
Resource availability
80
what are the 4 nursing roles?
magician: see the world through their eyes, use tricks to augment behavior

jester: use humor, spread joy, relations
81
What are the special considerations for caregiving in MCI, early-stage, and early onset dementia?
Focus on communication, behavior, and relationships
Individuals are aware of their diagnosis and need support to share their feelings and needs
Caregivers need support to deal with changing role, changing couple relationships, anger, frustration, uncertainty about the future, burden, and depression
