Cerebral Vascular Accident /Stroke
Prepared by: Marie Jean T. Aborde, RN1
Definition:
 A cerebral vascular accident (CVA), is an ischemic stroke or “Brain
Attack,” is a sudden loss of brain function resulting from a disruption of
the blood supply to a part of the brain. Stroke is the primary
cerebrovascular disorder in the United States.
 Strokes are usually hemorrhagic (15%) or Ischemic/ Nonhemorrhagic
(85%). Ischemic strokes are categorized according to their cause: large
artery thrombotic strokes (20%), small penetrating artery thrombotic
strokes (25%), cardiogenic embolic strokes (20%), cryptogenic strokes
(30%), and other (5%). Cryptogenic strokes have no known cause, and
other strokes result from causes such as illicit drug use, coagulopathies,
migraine, and spontaneous disection of the carotid or vertebral arteries.
The result is an interruption of the blood supply of the brain, causing
temporary or permanent loss of movement, thought, memory, speech
and sensation
Risk Factors
Nonmodifiable
 Advanced age (older than 55 years)
 Gender (Male)
 Race (African American)
Modifiable
 Hypertension
 Atrial Fibrillation
 Obesity
 Smoking
 Diabetes
 Carotid stenosis and valvular heart disease
 Periodontal disease
Clinical Manifestations

-

General sign and symptoms include:
numbness or weakness of face, arm, or leg (especially on one side of the
body), confusion or change in mental status, trouble speaking or understanding
speech; visual disturbances, loss of balance, dizziness, difficulty walking, or
sudden severe headache.

Motor loss
- Hemiplegia, hemiparesis
-

- Flaccid paralysis and loss of or decrease in the deep tendon reflexes (initial
clinical feature) followed by (after 48 hours) reappearance of deep reflexes and
abnormally increased muscle tone (spasticity).

Communication Loss
- Dysarthria (difficulty speaking)
- Dysphasia (impaired speech) or aphasia (loss of speech)
- Apraxia (inability to perform a previously learned action)
Perceptual Disturbance and Sensory Loss
- Visual perceptual dysfunctions (homonymous hemianopia (loss of half of the
visual field)
- Disturbances in visual spatial relations (perceiving the relation of two or more
 Sensory losses; slight impairment of touch or more severe

with loss of proprioception; difficulty in interrupting visual,
tactile, and auditory stimuli.
 Impaired Cognitive and Psychological Effects
Frontal lobe damage: Learning capacity, memory, or other
higher cortical intellectual functions may be impaired. Such
dysfunction may be reflected in a limited attention span,
difficulties in comprehension, forgetfulness and lack of
motivation.
Depression, other psychological problems: emotional
lability, hostility, frustration, resentment, and lack of
cooperation.
Assessment and Diagnostic Methods

examination
Noncontrast and CT scan
12-lead ECG and carotid ultrasound
CT Angiography or MRI and Angiography
Transcranial Doppler flow studies
Transthoracic or transesophageal
echocardiography
Xenon- enhanced CT Scan
Single photon emission CT (SPECT)
Prevention
 Help patients alter risk factors for stroke;

encourage patient to quit smoking, maintain a
healthy weight, follow a healthy diet (including
modest alcohol consumption), and to exercise
daily.
 Prepare and support patient through carotid
endarterectomy
 Administer anticoagulant agents as prescribed
(like low-dose aspirin therapy).
Medical Management
 - Recombinant tissue plasminogen activator (t-PA), unless

contraindicated; monitor for bleeding
- Anticoagulation therapy
- Management of increased intracranial pressure (ICP): osmotic
diuretics, maintain PaCO2 at 30 to 35 mm Hg, position to avoid hypoxia
(elevate the head of bed to promote venous drainage and to lower
increased ICP).
- Possible hemicraniectomy for increased ICP from brain edema in a
very large stroke.
- Intubation with an endotracheal tube to establish a patent airway, if
necessary
- Continuous hemodynamic monitoring (the goals for blood pressure
remain controversial for a patient who has not received thrombolytic
therapy; antihypertensive treatment may be withheld unless the systolic
blood pressure exceeds 220 mm Hg or the diastolic blood pressure
exceeds 120 mm Hg)
- Neurologic assessment to determine if the stroke is evolving and if
other acute complications are developing.
Management and Complications
 Decreased cerebral blood flow: Pulmonary care,

maintenance of a patent airway, and
administration of supplementary oxygen as
needed.
 Monitor for UTI’s, cardiac dysrrythmias, and
complications of immobility.
NURSING PROCESS
 The Patient Recovering From An Ischemic Stroke

Assessment
 During Acute Phase (1to 3 days)
 Weigh patient (used to determine medication
dosages), and maintain a neurologic flow sheet to
reflect the following nursing assessment parameters:
 Change in level of consciousness or responsiveness,
ability to speak and orientation
 Presence or absence of voluntary or involuntary
movements of the extremities: muscle tone, body
posture, and head position
Stiffness or flacidity of the neck
Eye opening, comparative size of pupils, and
pupillary reactions to light, and ocular position
Color of face and extremities, temperature and
moisture of the skin
Quality and rates of pulse and respiration; ABG’s,
body temperature, and arterial pressure
Volume and fluids ingested or administered and
volume of urine excreted per 24 hours
Signs of bleeding
Blood pressure maintained within normal limits.
 Postacute Phase
 Assess the following functions;

 - Mental status( memory, attention span, perception,

orientation, affect, speech/language).
 - Sensation and perception (usually the patient has
decreased awareness of pain and temperature).
 - Motor control ( upper and lower extremity
movement) swallowing ability, nutritional and
hydration status, skin integrity, activity tolerance, and
bowel and bladder function.
 - Continue focusing nursing assessment on
impairment of function in patient’s daily activities.
Diagnosis
Nursing Diagnosis
Impaired physical mobility related to hemiparesis, loss of
balance and coordination, spasticity, and brain injury
Acute pain related to hemiplegia and disuse
Deficient self-care (bathing, hygiene, toileting, dressing,
grooming, and feeding) related to stroke sequelae
Disturbed sensory perception (kinesthetic, tactile or visual)
related to altered sensory perception, transmission, and/or
integration
 Impaired swallowing
 Impaired urinary elimination related to flaccid bladder,

 Detrusor instability, confusion, or difficulty in


communicating
Impaired verbal communication related to brain
damage
Risk for impaired skin integrity related to hemiparesis
or hemiplegia, decreased mobility
Interrupted family processes related to catastrophic
illness and caregiving burdens
Sexual dysfunction related to neurologic deficits or
fear of failure
Collaborative Problems/Potential
Complications
 Decreased cerebral blood flow due to increased

ICP; inadequate oxygen delivery to the brain;
pneumonia
Planning and Goals
 The major goals for the patient (and family) may

include improved mobility, avoidance of shoulder
pain, achievement of self-care, relief of sensory
and perceptual deprivation, prevention of
aspiration, continence of bowel and bladder,
improved thought processes, achieving a form of
communication, maintaining skin integrity,
restored family functioning, improved sexual
function, and absence of complications.
 Goals are affected by knowledge of what the
patient was like before the stroke.
Nursing Interventions
 Improving Mobility and Preventing Deformities
 Establishing an exercise program

 Preparing for ambulation
 Preventing shoulder pain
 Enhancing self care
 Managing sensory- perceptual difficulties
 Assisting with nutrition
 Attaining bowel and bladder control
 Improving thought processes

 Improving communication
 Maintaining skin integrity
 Improving family coping
 Helping the patient cope with sexual

dysfunctionPromoting home and communitybased care
Evaluation
 Expected Patient Outcomes
- Achieves improved mobility
- Has no complaints of pain
- Achieves self-care; performs hygiene care; uses

adaptive equipment
- Demonstrates techniques to compensate for
altered sensory reception, such as turning the
head to see people or objects
- Demonstrates safe swallowing
- Achieves normal bowel and bladder elimination
- Participates in cognitive improvement program
- Demonstrates improved communication
- Maintains intact skin without breakdown
- Family members demonstrate a positive attitude
and coping mechanisms
- Develops alternative approaches to sexual
expression

Cerebral vascular accident

  • 1. Cerebral Vascular Accident /Stroke Prepared by: Marie Jean T. Aborde, RN1 Definition:  A cerebral vascular accident (CVA), is an ischemic stroke or “Brain Attack,” is a sudden loss of brain function resulting from a disruption of the blood supply to a part of the brain. Stroke is the primary cerebrovascular disorder in the United States.  Strokes are usually hemorrhagic (15%) or Ischemic/ Nonhemorrhagic (85%). Ischemic strokes are categorized according to their cause: large artery thrombotic strokes (20%), small penetrating artery thrombotic strokes (25%), cardiogenic embolic strokes (20%), cryptogenic strokes (30%), and other (5%). Cryptogenic strokes have no known cause, and other strokes result from causes such as illicit drug use, coagulopathies, migraine, and spontaneous disection of the carotid or vertebral arteries. The result is an interruption of the blood supply of the brain, causing temporary or permanent loss of movement, thought, memory, speech and sensation
  • 2. Risk Factors Nonmodifiable  Advanced age (older than 55 years)  Gender (Male)  Race (African American) Modifiable  Hypertension  Atrial Fibrillation  Obesity  Smoking  Diabetes  Carotid stenosis and valvular heart disease  Periodontal disease
  • 3. Clinical Manifestations  - General sign and symptoms include: numbness or weakness of face, arm, or leg (especially on one side of the body), confusion or change in mental status, trouble speaking or understanding speech; visual disturbances, loss of balance, dizziness, difficulty walking, or sudden severe headache. Motor loss - Hemiplegia, hemiparesis - - Flaccid paralysis and loss of or decrease in the deep tendon reflexes (initial clinical feature) followed by (after 48 hours) reappearance of deep reflexes and abnormally increased muscle tone (spasticity). Communication Loss - Dysarthria (difficulty speaking) - Dysphasia (impaired speech) or aphasia (loss of speech) - Apraxia (inability to perform a previously learned action) Perceptual Disturbance and Sensory Loss - Visual perceptual dysfunctions (homonymous hemianopia (loss of half of the visual field) - Disturbances in visual spatial relations (perceiving the relation of two or more
  • 4.  Sensory losses; slight impairment of touch or more severe with loss of proprioception; difficulty in interrupting visual, tactile, and auditory stimuli.  Impaired Cognitive and Psychological Effects Frontal lobe damage: Learning capacity, memory, or other higher cortical intellectual functions may be impaired. Such dysfunction may be reflected in a limited attention span, difficulties in comprehension, forgetfulness and lack of motivation. Depression, other psychological problems: emotional lability, hostility, frustration, resentment, and lack of cooperation.
  • 5. Assessment and Diagnostic Methods  History and complete physical and neurologic        examination Noncontrast and CT scan 12-lead ECG and carotid ultrasound CT Angiography or MRI and Angiography Transcranial Doppler flow studies Transthoracic or transesophageal echocardiography Xenon- enhanced CT Scan Single photon emission CT (SPECT)
  • 6. Prevention  Help patients alter risk factors for stroke; encourage patient to quit smoking, maintain a healthy weight, follow a healthy diet (including modest alcohol consumption), and to exercise daily.  Prepare and support patient through carotid endarterectomy  Administer anticoagulant agents as prescribed (like low-dose aspirin therapy).
  • 7. Medical Management  - Recombinant tissue plasminogen activator (t-PA), unless       contraindicated; monitor for bleeding - Anticoagulation therapy - Management of increased intracranial pressure (ICP): osmotic diuretics, maintain PaCO2 at 30 to 35 mm Hg, position to avoid hypoxia (elevate the head of bed to promote venous drainage and to lower increased ICP). - Possible hemicraniectomy for increased ICP from brain edema in a very large stroke. - Intubation with an endotracheal tube to establish a patent airway, if necessary - Continuous hemodynamic monitoring (the goals for blood pressure remain controversial for a patient who has not received thrombolytic therapy; antihypertensive treatment may be withheld unless the systolic blood pressure exceeds 220 mm Hg or the diastolic blood pressure exceeds 120 mm Hg) - Neurologic assessment to determine if the stroke is evolving and if other acute complications are developing.
  • 8. Management and Complications  Decreased cerebral blood flow: Pulmonary care, maintenance of a patent airway, and administration of supplementary oxygen as needed.  Monitor for UTI’s, cardiac dysrrythmias, and complications of immobility.
  • 9. NURSING PROCESS  The Patient Recovering From An Ischemic Stroke Assessment  During Acute Phase (1to 3 days)  Weigh patient (used to determine medication dosages), and maintain a neurologic flow sheet to reflect the following nursing assessment parameters:  Change in level of consciousness or responsiveness, ability to speak and orientation  Presence or absence of voluntary or involuntary movements of the extremities: muscle tone, body posture, and head position
  • 10. Stiffness or flacidity of the neck Eye opening, comparative size of pupils, and pupillary reactions to light, and ocular position Color of face and extremities, temperature and moisture of the skin Quality and rates of pulse and respiration; ABG’s, body temperature, and arterial pressure Volume and fluids ingested or administered and volume of urine excreted per 24 hours Signs of bleeding Blood pressure maintained within normal limits.
  • 11.  Postacute Phase  Assess the following functions;  - Mental status( memory, attention span, perception, orientation, affect, speech/language).  - Sensation and perception (usually the patient has decreased awareness of pain and temperature).  - Motor control ( upper and lower extremity movement) swallowing ability, nutritional and hydration status, skin integrity, activity tolerance, and bowel and bladder function.  - Continue focusing nursing assessment on impairment of function in patient’s daily activities.
  • 12. Diagnosis Nursing Diagnosis Impaired physical mobility related to hemiparesis, loss of balance and coordination, spasticity, and brain injury Acute pain related to hemiplegia and disuse Deficient self-care (bathing, hygiene, toileting, dressing, grooming, and feeding) related to stroke sequelae Disturbed sensory perception (kinesthetic, tactile or visual) related to altered sensory perception, transmission, and/or integration
  • 13.  Impaired swallowing  Impaired urinary elimination related to flaccid bladder,  Detrusor instability, confusion, or difficulty in     communicating Impaired verbal communication related to brain damage Risk for impaired skin integrity related to hemiparesis or hemiplegia, decreased mobility Interrupted family processes related to catastrophic illness and caregiving burdens Sexual dysfunction related to neurologic deficits or fear of failure
  • 14. Collaborative Problems/Potential Complications  Decreased cerebral blood flow due to increased ICP; inadequate oxygen delivery to the brain; pneumonia
  • 15. Planning and Goals  The major goals for the patient (and family) may include improved mobility, avoidance of shoulder pain, achievement of self-care, relief of sensory and perceptual deprivation, prevention of aspiration, continence of bowel and bladder, improved thought processes, achieving a form of communication, maintaining skin integrity, restored family functioning, improved sexual function, and absence of complications.  Goals are affected by knowledge of what the patient was like before the stroke.
  • 16. Nursing Interventions  Improving Mobility and Preventing Deformities  Establishing an exercise program  Preparing for ambulation  Preventing shoulder pain  Enhancing self care  Managing sensory- perceptual difficulties  Assisting with nutrition  Attaining bowel and bladder control  Improving thought processes  Improving communication
  • 17.  Maintaining skin integrity  Improving family coping  Helping the patient cope with sexual dysfunctionPromoting home and communitybased care
  • 18. Evaluation  Expected Patient Outcomes - Achieves improved mobility - Has no complaints of pain - Achieves self-care; performs hygiene care; uses adaptive equipment - Demonstrates techniques to compensate for altered sensory reception, such as turning the head to see people or objects - Demonstrates safe swallowing - Achieves normal bowel and bladder elimination
  • 19. - Participates in cognitive improvement program - Demonstrates improved communication - Maintains intact skin without breakdown - Family members demonstrate a positive attitude and coping mechanisms - Develops alternative approaches to sexual expression
