Cholinesterase inhibitors (3 generic names)donzepil, rivastigmine and galantamine
MOA Cholinesterase inhibitors: donzepil, rivastigmine & galantamineblocks enzyme that breaks down acetylcholine in synaptic cleft (↑'s amount of Ach in transmission)
Drug: memantine MOAprotect's the brain's nerve cells against the excessive glutamate that is released by cells damaged by AD.
What other aspect gets treated with medications other than increasing the availability of Acytelcholine?Depression, if treated may improve cognitive ability.
Depression of AD treatment drug classSSRIs

Nursing mgmt

Question Answer
Nursing Assessment: Important Health Info.head trauma, stroke, exposure to metals; prveious CNS infx; family hx of dementia. Meds: use of any drug to decrease sx
Nursing Assessment: functional health patternshealth perception-mgmt; nutritional-metabolic; elimination; activity-exercise; sleep-rest; cognitive-perceptual
Nursing DiagnosisImpaired memory; self-care deficit; risk for injury; wandering
Planning goalsmaintain functional ability for as long as possible; safe env't with a minimum of injuries; meet their personal care needs; maintain dignity.
Goals for care providerreduce caregiver stress; maintain personal, emotional & physical health; cope with the long-term effects of caregiving
Implementation: health promotionTBI is a risk factor for developing AD, so promote safety in activities. Recognize & treat depression early. Warn patients of early s/s.
Implementation: acute interventionDepression, denial, anxiety, fear & isolation is not unusual for patient to get, especially early on. Important job of nurse to assess for this. May need drug therapy/counseling. Inform family that there is not tx for AD, ongoing monitoring for both client & family is required.
Ambulatory & home care nursing care required depends on the stages of the disease, which varies. Depression is at early stage, inform that the progression is variable & care depends on which area of the brain is affected.
Behavioral problems (affect 90% of patients with AD)repetitiveness; delusions; illusions; hallucinations; agitation; aggression; altered sleep; wandering & resisting care.
Behavior problems are a patient's way of dealing with a precipitating factor.Could be in pain, frustrated, temp. extreme, anxiety. Careful intervention according to physical changes.
Intervention for a client who continues to pull out tubes, or dresssings.Cover with stretch tube gauze or remove them from their visual field.
sundowningpatient becomes more confused & agitated in the late afternoon or evening. Etiology unknown
Nursing interventions sundowningquiet, calm environment; maximize exposure to daylight; evaluate meds that cause sleep issues; limit naps & caffeine; consult with health care provider regarding drug therapy
Safety plan for patient is required as patient is at riskWandering is major concern; Medic Alert bracelet; decrease any stressful stimuli or triggers that may cause them to want to remove themselves from an area
Pain management, why is it hard to decipher pain with these patients?They have a difficult time expressing physical complaints, you must relay on cue's in behavior such as agitation or withdrawal.
Eating & swallowing difficultiesundernutrition d/t inability to feed themselves in later stages of AD.
Types of foods to give to help with difficulty swallowingpureed foods, thickened liquids & nutritional supplements. Patients may need reminders to chew their food, also good to decrease distractions during mealtime. Easy grip utensils & finger foods.
If oral feeding is no longer possible, what other routes may be used?NG for short periods. PEG (although can become dislodged, weigh positive/negative outcomes)
Oral careinspect mouth regularly; help with oral care to those who cannot perform self-care
Skin carenote any rashes, areas of redness & skin breakdown (malnutrition can put pt at higher risk)
urinary & fecal incontinence during middle & late stagesUse behavioral retraining of bladder and bowl function (scheduled toileting)
