11. CEREBROVASCULAR
ACCIDENT / STROKE
Cerebrovascular accident (CVA), or stroke, is
the sudden death of some brain cells due to a
lack of oxygen when the blood flow to the brain
is impaired by blockage or rupture of an artery
to the brain. Symptoms will depend on the area
of the brain affected.

America, behind heart disease and
cancer
Kills 160,000 people each year

year, 500,000 of those strokes could
be prevented

37. Nutritional Management
Principles of diet
Restrict total calories to reduce body
weight and maintain it at the normal for
height, age and sex.
It is not desirable to restrict all kind of
fat. It should consist of 30% of total
calories
Unsaturated fat is preferred and
saturated fat and animalfat is reduced.

38. Green leafy vegetables, fruits, cereals,
skimmed milk are encouraged.
Three or four small meals are
preferable compared to large meals.
Regular exercise is useful.

40. Nursing Assessment
1. Maintain neurologic flow sheet
during acute phase.
2. Assess for voluntary or involuntary
movements, tone of muscles, and
presence of deep tendon reflexes
3. Also assess mental status, cranial
nerve function, sensation /
propriception, bladder control.

41. 4. Monitor bowel and bladder function.
5. Monitor effectiveness of
anticoagulation therapy.
6. Frequently assess level of function
and psychosocial response to
condition.

42. Nursing Diagnoses
A. Risk for Injury related to neurologic
deficits
B. Impaired Physical Mobility related to
motor deficits
C. Altered Thought Processes related
to brain damage
D. Impaired Verbal Communication
related to brain injury
E. Self-care Deficit (bathing. dressing,
toileting) related to hemiparesis/
paralysis

43. F. Imbalanced Nutrition: Less Than
Body Requirements, related to
impaired self-feeding, chewing,
swallowing
G. Impaired Urinary Elimination related
to motor/sensory deficits
H. Altered Family Process related to
catastrophic illness, cognitive and
behavioral sequelae of stroke, and
care-giving burden

44. Nursing Interventions
A. Preventing Falls and Other Injuries
1. Maintain bed rest during acute phase
(48 to 72 hours after onset of stroke) with
head of bed slightly elevated and side rails
in place.
2. Administer oxygen as ordered during
acute phase to maximize cerebral
oxygenation.
3. Frequently assess respiratory status,
vital signs, heart rate and rhythm, and
urinary output to maintain and support vital
functions.

45. Nursing Interventions
4. When patient becomes more alert
after acute phase, maintain frequent
vigilance and interactions aimed at
orienting, assessing, and meeting the
needs of the patients.
5. Try to allay confusion and agitation
with calm reassurance and presence

46. Nursing Interventions
B. Preventing Complications of
Immobility
1. Use a foot board during flaccid period
after stroke to keep loot dorsiflexed; avoid
its use after spasticity develops.
2. Avoid excessive pressure on ball of foot
after spasticity develops.
3. Do not allow top bedding to pull affected
foot into plantar flexion.

47. Assisting for Mobility

48. Nursing Interventions
4. Maintain functional position of all extremities.
a. Apply splints and braces as needed—volar
splint to support functional position of wrist, sling
to prevent shoulder subluxation of flaccid arm,
high-top sneaker for ankle and foot support.
Splints support flaccid extremities and can also
be used on spastic extremities to decrease
stretch stimulation and reduce spasticity

49. Nursing Interventions
c. Place a pillow in the axilla of the
affected side when there is limited external
rotation to keep arm away from chest and
prevent adduction of the affected shoulder.
d. Place the affected upper extremity
slightly flexed on pillow supports with each
joint positioned higher than the preceding
one to prevent edema and resultant
fibrosis; alternate elbow extension.
e. Place the hand in slight supination with
fingers slightly flexed.

50. Nursing Interventions
f. Place the patient in a prone position
for 15 to 30 minutes daily and avoid
sitting up in chair for long periods to
prevent knee and hip flexion
contractures.
5.Exercise the affected extremities
passively through range of motion four
to five times daily to maintain joint
mobility and enhance circulation;
encourage active range-of-motion
exercise as able.

51. Nursing Interventions
6. Teach patient to use unaffected
extremity to move affected one.
7. Prepare for ambulation cautiously.
a. Check for orthostatic hypotension.
b. Graduate the patient from a reclining
position to head elevate, and dangle legs
at the bedside before transferring out of
bed or ambulating; assess sitting balance
in bed.

52. Exercising the affected
extremity

53. Nursing Interventions
c. Assess the patient for excessive
exertion.
d. Have patient wear walking shoes.
e. Assess standing balance and have
patient practice standing
F. Help patient begin walking as soon
as standing balance is achieved,
ensure safety with a patient waist belt.

54. Nursing Interventions
C. Optimizing Cognitive Abilities
1. Be aware of patient’s cognitive alterations and
adjust interaction and adjust interaction and
environment accordingly.
2. Participate in cognitive retraining program—
reality orientation, visual imagery, cueing
procedures—as outlined by occupational or
rehabilitation therapist.
3. Use pictures of family members, clock,
calendar; post schedule of daily activities where
patient can see.
4. Focus on patient strengths and give positive
feedback.

55. Nursing Interventions
F. Promoting Adequate Oral Intake
1. Help patient release swallowing
sequence.
a. Have patient attempt to suck on gloved
finger to strengthen oral musculature.
b. Place ice on tongue and encourage
sucking.
c. Progress to popsice and soft foods.
d.. Make sure soft diet is provided, based
on ability to chew.

56. Nursing Interventions
2. Encourage small, frequent meals and
allow plenty of time.
3. Remind patient to chew on unaffected
side.
4. Inspect mouth for food collection or injury
and encourage frequent oral hygiene.
5. Teach the family how to assist the patient
with meals to facilitate chewing and
swallowing.

57. Nursing Interventions
5. Teach the family how to assist the patient with
meals to facilitate chewing and swallowing.
a. Reduce environmental distractions improve
patient concentration.
b. Provide oral care before eating to improve
aesthetics and afterward to remove food debris.

58. Nursing Interventions
c. Position the patient so he or she is
sitting with 90 degrees of flexion at the
hips and 45 degress of flex-ion at the
neck. Use pillows behind the back and
along the weak side to achieve correct
position.
d. Maintain position for 30 to 45
minutes after the meals to prevent
regurgitation and aspi-ration.

59. Nursing Interventions
E. Facilitating Communication
1. Speak slowly, use visual cues and
gestures; be consistent and repeat as
necessary.
2. Give plenty of time for response,
and reinforce correct responses.
3. Minimize distractions.
4. Use alternative methods of
communication other than verbal.

60. Nursing Interventions
F. Fostering Independence
1.Teach patient to use nonaffected side of
activities of daily living (ADL) but not to
neglect the affected side.
2. Adjust the environment ( call, light, tray)
to side of awareness if special neglect or
visual field cuts are present, approach the
patient from uninvolved side.
3.Teach the patient to scan environment if
visual deficits are present.

61. Nursing Interventions
4.Encourage family to provide clothing
that is a size larger than the patients
wears with front closure teach patient
to dress while sitting to maintain
balance
5.Ensure that personal care items,
urinal, commode, etc. are nearby and
that patient obtains assistance with
transfers and other activities as
needed
