Q

Interventions of delirium

A
  • Keep patient safe, keep client safe, re-orient them and look for the underlying cause.
  • Most effective approach to delirium is prevention.
  • Understand delirium is common with the elderly and keep them oriented
  • Delirium is not apart of normal aging.
  • There is a progressive loss of intellectual ability and interferes with daily care.

Q

Dementia

A
  • Symptoms are subtle and is a slow progressive decline of memory and thinking cells
  • Due to gradual dysfunction and loss of brain cells.
  • Types of dementia include vascular dementia, lewy bodies dementia, degenerative, neoplastic, demyelination, infectious, inflammatory, toxic, metabolic, and psychiatric.
  • Alzheimer’s is not reversible, it is progressive.

Q

Interventions of alzheimers

A
  • Patient can become anxious, suspicious, agitated, delusional, hallucinations or even violent.
  • It is a complex brain disorder sometimes called senile dementia.
  • This is not normal with aging
  • 6th leading cause of death, due to patients becoming immobile, not being to eat. Affects about half of the people 85+

Q

Oxidative Stress/Types of Alzheimer’s

A
  • Plays a role in the pathology of the disease

Genetic Familial Early Onset Alzheimer’s
- Genetic Component

- Etiology is unknown

Q

Alzheimer’s Disease

A
  • Aging is a risk factor of the cause
  • Pathogenesis is uncertain
  • Decrease in brain size, neuropathologic and biochemical changes that interfere with neuro transmission, neuro transmitter acetylcholine is principally affected.
17
Q

Early Sign’s of Alzheimer’s

A
  • Forgetful, subtle memory loss

- Confusion, restlessness, mood swings, difficulty interpreting visual information.

18
Q

General Manifestations of Alzheimer’s

A
  • Global cognitive decline
  • Behavior changes and loss of function
  • 7 Stages of Alzheimer’s
  • 7th stage is where a person is near death.
    (Not able to swallow)
  • Definitive diagnoses of Alzheimer’s is done via Autopsy
19
Q

Nursing interventions for Dementia/Alzheimer’s

A
  • First check if it is due to reversible Dementia
    (Infection, Electrolyte Imbalance, Glucose)
  • Diagnoses is based on ruling out other things with labs, history, physical scan, MRI, depression.
20
Q

Nursing Interventions Alzheimer’s

A
  • Promote patient function and independence as long as possible
  • Promote Safety
  • Reduce anxiety and agitation
  • Meds cannot cure Alzheimer’s but they can help slow onset or manage symptoms
  • Meds can also be given to treat anxiety.
  • Help patient improve communication
21
Q

Nursing Interventions Alzheimer’s

A
  • Promote adequate nutrition
  • Promote balanced activity and rest
  • These patients are typically cared for in a home setting or long term care setting by family members and caregivers
  • Goals of medication is to slow the loss of memory and cognition
22
Q

Cholinesterase Inhibitors

A
  • Prescribed for mild to moderate cases of Alzheimers
  • Aricept is also common, that increases acetylcholine in the brain and slows neural degeneration. (cholinesterase inhibitor for mild - moderate)
23
Q

NMDA receptor antagonist

A
  • Used for moderate to severe cases of Alzheimer’s
    N-Methyl-D-aspartic receptor antagonist (Namenda)
  • Prevents overstimulation of glutamate receptors
24
Q

Combo Drugs

A
  • Combines actions of drugs prior mentioned
  • Namzaric combo of Cholinesterase inhibitor and NMDA Receptor Antagonist.
  • Typically as patients move down the 7 stages of Alzheimer’s drugs are discontinued as there is no more use.
  • Antidepressants, anti-anxiety medication, anti-psychotics may also be used.
25
Q

Stroke

A
  • Deprives brain cells of oxygen
  • Quick medical care is critical
  • Brain consumes 20% of oxygen in the blood
  • Carotid arteries supply front of brain oxygen and vertebral arteries supply the back of the brain
26
Q

Hemorrhagic Stroke

A
  • Perforated vessel allows blood to leak out
  • 25% of all strokes
  • Vessels of Circle of Willis are most common
  • Vasospasm caused by hemorrhagic stroke can cause secondary strokes
27
Q

Aneurysm

A
  • Arteries balloon out
  • Happens commonly in the circle of Willis in the brain
  • Weakened parts of artery walls
  • Ruptured Aneurysm can cause Hemorrhagic stroke
28
Q

Arteriovenous Malformation

A
  • Capillaries are missing between arteries and veins so high blood pressure from arteries go straight into veins which is not good.
  • This puts arteries/veins at high risk of rupturing which can cause a hemorrhagic stroke.
29
Q

Ischemic Stroke

A
  • Most common type
  • Clot blocks artery
  • Embolism from dysrhythmia can cause a clot
  • The area the clot blocks from oxygen will determine the type of symptoms the patient may have
  • Body will try to compensate by diverting blood flow to affected area
30
Q

Treatment for stroke

A
  • 1st step is IV Medication called Tissue Plasminogen Activator (TPA) which breaks the blood clot
  • Medication given with 4.5 hours greatly increases a persons chances of survival
  • Endovascular Thrombectomy - Inserts small thin catheter through the leg all the way to the blockage then pull the clot out
31
Q

How to tell if someone is having a stroke

A

F - Facial drooping when trying to smile
A - Arm Weakness
S - Speech difficulties (ask to repeat a phrase)
T - Time

32
Q

Ischemic Stroke

A
  • Can be caused by embolism clot (travels)

- Thrombosis clot (local) (Atherosclerosis)

33
Q

Lacunar Stroke

A
  • Small vessel stroke due to hypertension and vessel walls thickening. When vessel walls thicken, less blood can travel through them, limiting the oxygen going to the brain.
34
Q

Watershed Stroke

A
  • Atherosclerosis prevents enough blood to get to the brain
  • Hypoperfusion
  • Water shed area is the area of the brain that is not getting much oxygen due to atherosclerosis. Usually in the middle of the hemisphere of the brain.
