Stroke, or cerebrovascular accident (CVA), is a critical medical condition characterized by the interruption of blood flow to the brain. This deprivation of oxygen and nutrients can lead to rapid brain cell damage, resulting in a range of neurological deficits. For nurses, accurate and timely assessment and intervention are paramount in stroke care. A crucial aspect of this care is formulating appropriate nursing diagnoses for stroke, which guide the nursing care plan and contribute significantly to patient recovery and positive outcomes.
Types of Stroke: Impacting Nursing Diagnoses
Understanding the different types of stroke is fundamental as they influence the clinical presentation and subsequent nursing diagnoses. Strokes are broadly classified into two main categories: ischemic and hemorrhagic.
Ischemic Strokes: These are the most common type, accounting for approximately 87% of all strokes. Ischemic strokes occur when a blood vessel supplying the brain becomes narrowed or blocked, drastically reducing or completely stopping blood flow. This blockage is often due to:
- Thrombosis: Formation of a blood clot within a cerebral artery.
- Embolism: A blood clot or other debris traveling from another part of the body (often the heart) and lodging in a cerebral artery.
- Systemic Hypoperfusion: Reduced blood flow to all parts of the body, including the brain, often due to heart failure or severe hypotension.
Hemorrhagic Strokes: These occur when a blood vessel in the brain ruptures, leading to bleeding into the brain tissue or surrounding spaces. The two main types of hemorrhagic stroke are:
- Intracerebral Hemorrhage: Bleeding directly into the brain tissue. This is often caused by hypertension, arteriovenous malformations (AVMs), or amyloid angiopathy.
- Subarachnoid Hemorrhage: Bleeding in the space between the brain and the surrounding membrane (subarachnoid space), frequently caused by a ruptured aneurysm or head trauma.
Transient Ischemic Attacks (TIAs): Often referred to as “mini-strokes,” TIAs are temporary episodes of neurological dysfunction caused by brief interruptions in blood flow to the brain, spinal cord, or retina. Symptoms are similar to stroke but resolve within minutes to hours, typically within 24 hours, without causing permanent brain damage. TIAs are warning signs and significantly increase the risk of future strokes.
Understanding the different types of stroke, including ischemic and hemorrhagic, is critical for accurate nursing diagnosis and effective care planning.
The Nursing Process in Stroke Care: Foundation for Nursing Diagnosis
The nursing process is a systematic approach to patient care, and it is especially critical in the management of stroke patients. This process includes assessment, diagnosis, planning, implementation, and evaluation. For stroke patients, the nursing process is dynamic and requires continuous monitoring and adaptation due to the potential for rapid changes in neurological status.
Nursing Assessment: The initial and ongoing assessment is vital to identify patient needs and formulate appropriate nursing diagnoses. This involves gathering both subjective and objective data.
Subjective Data in Stroke Assessment
Subjective data is obtained from the patient (if possible) or family members and includes:
-
Patient’s Symptoms: Elicit a detailed account of the onset, nature, and progression of symptoms. Key symptoms indicative of stroke include:
- Sudden weakness or paralysis (hemiparesis/hemiplegia), often on one side of the body.
- Sensory disturbances like numbness or tingling (paresthesia).
- Difficulty swallowing (dysphagia).
- Visual changes, such as vision loss in one or both eyes, double vision (diplopia).
- Speech difficulties, including:
- Expressive aphasia (Broca’s aphasia): Difficulty producing speech.
- Receptive aphasia (Wernicke’s aphasia): Difficulty understanding speech.
- Dysarthria: Difficulty articulating words due to muscle weakness.
- Balance and coordination problems (ataxia).
- Changes in mental status, confusion, or decreased level of consciousness.
-
Time of Onset: Precisely determine when symptoms started or when the patient was last known to be at their baseline. This “last known well” time is crucial for determining eligibility for thrombolytic therapy (tPA).
-
Risk Factors: Identify pre-existing conditions and lifestyle factors that increase stroke risk:
- Hypertension
- Diabetes Mellitus
- Hyperlipidemia
- Smoking
- Obesity
- Atrial Fibrillation and other heart conditions
- Family history of stroke
- Advanced age
- Ethnicity (higher risk in African Americans and Hispanics)
- Certain medications (e.g., birth control pills containing estrogen)
- Substance abuse (cocaine, amphetamines)
- Sedentary lifestyle and unhealthy diet
-
Medical and Family History: Gather detailed information about past medical conditions, surgeries, and family history of stroke or cardiovascular disease.
-
Medication History: Review all current medications, including over-the-counter drugs and supplements, paying attention to anticoagulants, antiplatelets, and antihypertensives.
Objective Data in Stroke Assessment
Objective data is gathered through physical examination and diagnostic tests.
-
F.A.S.T. Assessment: Utilize the F.A.S.T. acronym for rapid stroke recognition:
- Face: Check for facial drooping.
- Arms: Assess for arm weakness (ask the patient to raise both arms).
- Speech: Check for slurred or difficult speech (ask the patient to repeat a simple sentence).
- Time: Note the time of symptom onset and call emergency services immediately.
-
ABCs: Assess Airway, Breathing, and Circulation immediately to ensure basic life functions are stable. Stroke patients are at risk for airway obstruction, aspiration, and respiratory distress.
-
Neurological Examination: Perform a comprehensive neurological assessment using tools like the National Institutes of Health Stroke Scale (NIHSS) to quantify neurological deficits. The NIHSS evaluates:
- Level of Consciousness
- Eye movements (Gaze)
- Visual fields
- Facial symmetry
- Motor function of arms and legs
- Limb ataxia
- Sensory function
- Language and speech (Aphasia, Dysarthria)
- Neglect (Inattention)
-
Vital Signs: Monitor blood pressure, heart rate, respiratory rate, and temperature. Hypertension is common in acute stroke, but rapid lowering can be harmful.
-
Diagnostic Tests: Prepare the patient for and review results of diagnostic procedures:
- Blood Glucose: Rule out hypoglycemia, which can mimic stroke symptoms.
- Brain Imaging (CT or MRI): Differentiate between ischemic and hemorrhagic stroke and rule out other conditions. CT is typically the first-line imaging due to speed and availability. MRI provides more detailed images but takes longer.
- CT Angiography (CTA) or MR Angiography (MRA): Visualize blood vessels and identify blockages or aneurysms.
- Carotid Ultrasound: Assess for carotid artery stenosis.
- Electrocardiogram (ECG): Detect cardiac arrhythmias, such as atrial fibrillation, which can be a cause of embolic stroke.
- Laboratory Tests: Complete blood count (CBC), coagulation studies, lipid profile, cardiac biomarkers, toxicology screen to identify underlying causes and guide treatment.
A thorough stroke assessment, including neurological exams and diagnostic procedures, is essential for identifying appropriate nursing diagnoses.
Common Nursing Diagnoses for Stroke Patients
Based on the comprehensive assessment, nurses formulate nursing diagnoses to address the patient’s needs and problems. These diagnoses are crucial for developing individualized care plans. Some of the most common nursing diagnoses for stroke patients include:
