MCI – Mild Cognitive Impairment | This is not an actual dx of dementia; it involves Short-term memory loss;Intact daily fxn |
Treatment for MCI | Tx- Calendar, memos, etc; can live alone...cue cards to help them to remember. |
Does MCI stabilize or progress? | Sometimes it stabilizes...while other times it does progress to Alzheimers. |
Stage 1 of Alzheimers | lasts 2-4yrs |
Stage 1 of Alzheimers | Short tem memory loss Disorientation – time / place Language, word loss Concentration, Abstract thinking Difficulty with familiar routines, misplacing items Alert, sociable Mood, personality |
Stage 1 of Alzheimers - Subtle, Family compensates? | It generally starts out as forgetfulness, or misplacing things...it's very subtle in that family and patient just sort of brush it off as forgetfulness. |
Stage 1 of Alzheimers..forgetfulness interfering with daily living...withdrawing? | Generally, people in stage 1 AD are functioning and getting around...but sometimes forget where they are or misplace things. |
Stage 2 of AD- characteristics | This is the Longest of the stages; they get lost in familiar places; they are unable to recognize faces, names; they often have Illusions; Easily irritated, Paranoia, Depression, Sleep Sundowning, Unable to follow conversations, Language deficits, writin |
Stage 2 of AD - other characterisitics | Difficulty with simple tasks (ADLs) Loss abstract thinking Agnosia (objects) Apraxia (routines) Gait changes Score low on the MMSE |
Stage 3 of AD - characteristics | Unable to recognize others;self Decline & impaired verbalization; Incontinence;Unable to care for self (forgetful);Delusions; Complications (pneumonia, dehyd, nutrition, falls, behavior) |
Assessing and dgx dementia and delirium- history | You are going to ask about History (family);Medical Meds (last dose, etc); Drugs &/or ETOH consumption; Environment (hazards) |
Assessing and dgx dementia and delirium - lab testing | They will want to do further tests to rule out other by looking aat Thyroid;Vit B;Infection or Metabolic;CT /MRI |
Assessing and dgx dementia and delirium - other testing | Cognitive Tests – (MMSE) and assessing if their ability to meet ADLs |
Nursing care for treating pt with AD or delirium who has a disturbed Thought Process | Nurse should try to reorient prn (clocks, calendars); |
With regards to nsg dgx of Disturbed Thought Process at what stage is re-orienting not useful? | Stage 1 pt can be reoriented, with clocks, calendars, cue cards...stage 2 or 3 it is not helpful |
Disturbed thought process for AD or Delirium - some helpful tips | You'll want to Address hallucinations (i.e.“..you are at the hospital..”) also 1:1 time is helpful |
Disturbed thought process for AD or Delirium - offering consistent routines | This would include Same care-giver, Family members. |
Assess nonverbals help with? | Non verbals help with identify triggers...what causes them to get agitated (maybe they start getting restless when they have to go pee) |

Nursing care for dementia pt- ways to avoid injury | Personal alarms, door locks detect if pt is moving about; Avoid physical restraints as these will increase agitation- have Family members help out with the dementia pt;1:1 time; allow frequent toileting (Urgency is common with elderly- leading to accident |
Monitor behavior & agitation of a dementia pt. | Doing this will help Identify/prevent triggers; Face client, call by name, calm voice;Identify self, simple explanations Yes/No questions; Redirect if possible. |
Why does redirection work for the elderly? | Redirection usually works for dementia pts b/c they have short term memory (unable to learn new things) |
Nursing care for some one who has sleep disturbed patterns. | Limit distractions;low lights, calm environment Keep awake during daytime hrs Dementia pts often have reversed sleep patterns |
Nursing care for someon who has a knowledge defecit rt meds. | Antipsychotic Meds (severe agitation) Haldol (Haloperidol) Risperidal (Risperidone) Zyprexa (Olanzapine) Seroquel (Quetiapine fumate) |
What are nursing considerations before administering antipsychotic meds? | Priority is to redirect the pt and document that you tried preventing to give meds- these sort of drugs are considered a form of restraint. |

Pt has been given haladol and you notice that he is involuntarily shaking and jerking. What do you need to do? | The pt needs to be taken off this med...haladol has a side effect that causes involuntary movement. |
what are nursing considerations when taking haladol? | Pt is at risk for Ortho Hypotn and should be assessed for Falls; This is an antiCholenergic med that causes Dry Mouth, constipation, urinary retention; haladol causes Sedation increasing the risk for Falls and Social isolation |
what do diabetics need to consider when taking Haladol? | Diabetics may need to increase insulin. |
T or F. Some patients who require insulin while taking haladol aren't necessarily diabetic. | True- pts who are given haladol may still need to take insulin even if they aren't diabetic. |

Acetylcholinesterase Inhibitor N-methyl-D aspartate receptor antag treats behavior of a pt that show which s&s? | Tx behavioral s/s also Psychosis, depression, and agitation |
Cholinesterase Inhibitors - what does it treat? | tx of MILD to MOD symptoms; Improve Cog Fxn and Delay Behavior s/s |
Cholinesterase Inhibitors- brand names of these drugs | Donezpil (Aricept)*** QD is used first, and then Rivastigmine (Exelon) is the second most common of this class of drugs. lantamine (Razadyne) is the least given because it causes liver damage. |
Cholinesterase Inhibitors actions: | This med Slows the breakdown of acetylcholine; it helps to slows memory loss & decline and Improve cognitive fxn (ADLs); as well as Decrease/delay agitation & delusions |
Cholinesterase Inhibitors sideeffects: | GI – N/V/D, bradycardia, sleep chngs |
Cholinesterase Inhibitors - nursing considerations | Don’t stop abruptly (s/s will return rapidly -behave); Liver studies if patient is taking(razadyne);it takes 6-12 months to eval full effect; can start taking it once MMSE < 12 little effect |
Cholinesterase Inhibitors- nursing goal | Improve cognitive function and behavior;maintain where they are at; majority of people taking this drug will see an improvement. |
Which drug do give along side of Arocept? | Namenda |
NMDA Receptor Blockers - Memantine (Namenda); Actions: | This med is used for the Tx mod to severe dementia; Temporary improvement of Cognitive and Behave s/s; (vascular dementia) |
