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

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

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

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

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

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
Q
  • curved forks that fit over the hand, rounded plates help keep food on the place, special grips and swivel handles are helpful, knives with rounded blades are rocked back and forth to cut, plate guards to help keep food on the place, and cup with special handle
