Q
  • hypertension: number one greatest risk factor=edu can encourage to take med to keep in control,
    -other heart disease= a fib-throw clot from heart up in brain: keep up on meds to keep reg rhythm,
    -diabetes 4-5 times greater risk of a stroke,
    -Diet: cholesterol, low sodium, avoid tobacco, be more active, limit obesity,
    -oral contraceptives= low dose as possible, no good idea to add if overweight or smoke
    -sickle cell anemia=blood is clumping, onset of episodes which will have less viscosity of the blood and won’t move as well, do things to prevent exacerbation
    cocaine use
    excessive alcohol usage= men greater than 2 drinks per day/ women greater than 1 drink per day
A

Modifiable risk factors for a stroke

1
Q

-protective mechanisms to help maintain blood flow even when things are happening in the body, does it by cerebral vasodilation=keep as much blood there as possible

A

Cerebral auto regulation

factors that affect blood flow

2
Q
  • highest percentage of the major types of stroke it is 80%, from inadequate blood flow to brain, obstruction of the brain, some are partial or complete of occlusion, blood is unable to pass through the artery, more gradual onset
A

ischemic stroke

3
Q
  • dev from rupture of artery, bleed into the brain tissue, 15 percent, sudden in onset, higher mortality rate
A

hemorrhagic stroke

4
Q

narrowing of blood vessels over time Ex: atherosclerosis=plaque buildup in the artery over time build up enough to gradually occlude and block the artery partially or completely
-develop clot in that area of the artery
Often do occur during sleep, or right after awake
-bp decreases: already have impeded blood flow, now bp is not as forceful as during the day, more risk
- Affects depends on how large and much tissue is involved

A

Types of Ischemic Stroke

1a. Thrombotic-

5
Q

Types of Ischemic Stroke

A

thrombotic
lacunar
embolic
transient ischemic attacks

6
Q
  • dev of area of injury occurred in smaller artery not a main one, ruptures into the brain tissue, hole dev in the tissue, more rare than 2 other types
A

Lacunar stroke

ischemic

7
Q
  • clot that originates from another part in the body,
    Ways to have:
    A. a fib= left chamber of heart thrown into the carotid artery
    B. plaque formation from somewhere else
    -occur more suddenly
A

1c. Embolic

ischemic

8
Q

-Episodes of neurological deficit
-Resolves in minutes to hours
-Considered a warning sign for a stroke= concerned for future stroke, will be put on preventative med
-Temporary loss of neuro function, mini stroke, onset with stroke like symptoms, last usually 3-24 hours, short onset, most often related to microemboli= temporary block flow of blood
1/3 will never have another one, 1/3 can progress into a stroke, 1/3 will keep having onsets of tias after initial episode

A

1d. Transient Ischemic Attacks

ischemic

9
Q
  • area around the area of injury, the tissue that is at risk
A

Pneumbra

10
Q

– within the brain tissue, hypertension is the number one cause that can cause that aneurysm to ruptured, sudden onset, associated with activity
-high mortality, 50% of people die in 48 hours, high risk for rebleeding= which increases mortality rate as much as 80 percent

A

2a. Intracerebral

hemoragic stroke

11
Q
  • from a rupture or bleed Ex: aneurysm, artery ruptured, trauma
    Both= at risk for cerebral vasospasm= in cerebral artery massive vasoconstriction of the blood flow to the brain, prevent that, more of the subarachnoid than the intracerebral, high risk could cause further damage
A
  1. Hemorrhagic Stroke
12
Q

Sx: very severe headache, n/v, decreased level of consciousness, high bp

A

intracerebral hemorrhagic stroke

13
Q

rupture into that space, mortality rate 40%, high risk to bleed after it has stopped,

A

2b. Subarachnoid-

hemorrhagic stroke

14
Q

Sx: sudden severe headache, *heard a pop, can have same symptoms

A

subarachnoid hemorrhagic stroke

15
Q

decreased cerebral blood flow= rupturing in brain tissue ->, increased cerebral edema-> increases pressure in the brain-> herniation-> can displace tissue/ will get less blood flow and more cell death

A

Pathophysiology: Hemorrhagic Stroke-

16
Q

droopy face, paralysis of one side of the body, slurred speech, arm drop=weakness of one side or the other, vision problems, complain of headache, common onset symptoms of dizziness

ct

52
Q

what is able to lice a clot, break up clot to allow blood to flow through artery, can be given iv, can be given in the groin or in the brain
-not given with hemorrhagic, good assessment: won’t be given with recent bleed= gi, want to know major surgeries, on Coumadin
Recommendation- needs to be given in 4.5 hours of onset

54
Q

A. = allow some
B. = extra fluid bc want intravascular volume to be higher, more fluid in there less likely vessels will clamp down don’t want in overload
C. - fluid to dilute blood thinner and flows easier
*treat any type of hyperthermia- brain metabolism increases which increases brain damage, running a fever= Tylenol to bring down

A

Emergency Management

57
Q
  • initially very often q 1 hour then 2 then 4 hours

    2. Verbal response: orientated, confused, inappropriate, incomprehensible, none
    3. Motor response: obeys commands, localizes to pain, withdraws from pain, flexion to pain, none
  • Higher the score the better, lowest score can get is a 3, max score can get is 15

ABC=Respiratory: stable, aren’t affected
- May need a vent
Ongoing assessment
Oxygenation
Suctioning/airway clearance

- Monitor ICP

A

Nursing Implementation Neurological

69
Q

VS
Fluid balance- to prevent vasospasm
Cardiac rhythm/heart sounds
DVT prevention- bed ridden for a while because lack of mobility, don’t want another emboli

A

Cardiovascular

70
Q

-Position to prevent edema: elevate extremities
-Prevention of contractures
-careful with moving patient: support side that is flaccid, use two people, use a gait belt, don’t grab flaccid arm, tuck arm back so it isn’t in the way
Best to move them to non-affected side to the chair able to grab chair, strong side to where you are going
Prevention of muscle atrophy
Rehab: balance training, CIMT= constraint induced movement therapy, strengthening that side want to work that side, will make them work down the road, will be several weeks after initial, further along

A

Nursing Implementation specific to stroke Musculoskeletal

71

Intermittent catheterization program- short term
Bladder training

A

Nursing Implementation Gastrointestinal

73
Q

Assess swallowing- risk for aspiration
swallow eval : to check if aspiration
-difficulty found will have speech therapist consulted, set up guidelines for swallowing precaution
Initiate swallowing precautions
Have to be cleared to eat
High fowler’s position when eating: up in chair
Head flexed forward- tuck chin when swallow
Swallow and swallow again: 2 for every bite, small bites =right side might shovel food in
Thickening agents- usually referred to things other than water= no bacteria
Frazier water protocol- no water with meals
Learn to place food on the unaffected side of mouth- chew better and stronger
Crush medicine so aren’t swallowing pill
Check and open mouth for pocketing periodically- eat and when take medicine, look like the swallowed
Need good mouth care- before can stimulate appetite, and after to make sure no food is left
Visual fields having difficulty seeing, right side neglect wont eat that side/ see if can see and within reach/ will need guidance
* we should be there to watch eating to asses swallowing for first couple of times/ don’t delegate to can

A

Nursing Implementation Nutrition

74
