Strokes - Nursing Case Study

Pathophysiology

• Primary mechanism: Ischemic strokes occur when a blood clot obstructs a cerebral artery, reducing blood flow and oxygen supply to brain tissue. This leads to cell death and loss of neurological function in the affected area.

• Secondary mechanism: Hemorrhagic strokes result from the rupture of a blood vessel in the brain, causing bleeding and increased intracranial pressure. This disrupts normal brain function and damages surrounding tissue.

• Key complication: Both types of strokes can lead to cerebral edema, which further compromises blood flow and exacerbates brain injury. Prompt intervention is crucial to minimize long-term neurological deficits.

Demographics:

65-year-old female, retired school teacher

History:

• Key past medical history: Hypertension, Type 2 Diabetes, Atrial Fibrillation

• Current medications: Metformin 500 mg twice daily, Lisinopril 10 mg daily, Warfarin 5 mg daily

• Allergies: Penicillin

Current Presentation:

• Chief complaint: Sudden onset of weakness on the right side of the body

• Key symptoms: Slurred speech, facial droop on the right side, difficulty walking, headache

• Vital signs: Blood pressure 180/100 mmHg, heart rate 110 bpm, respiratory rate 22 breaths per minute, temperature 98.6°F

Section 1

As the medical team conducts an initial assessment, they observe that the patient exhibits significant right-sided hemiparesis, with a notable decrease in motor strength in both the right arm and leg. Her slurred speech persists, and she struggles to articulate words clearly, suggesting aphasia, which indicates possible involvement of the left hemisphere of the brain. The facial droop is pronounced on the right side, and the patient has difficulty maintaining balance, which corroborates the likelihood of an ischemic stroke affecting the left middle cerebral artery territory. The team prioritizes obtaining a CT scan to confirm the type of stroke and rule out hemorrhage, given the elevated blood pressure of 180/100 mmHg and the history of atrial fibrillation predisposing her to embolic events.

The CT scan results reveal an area of ischemia in the left cerebral hemisphere, confirming an ischemic stroke. There is no evidence of hemorrhage, which allows the consideration of thrombolytic therapy, although the patient's elevated blood pressure poses a risk that must be managed promptly. Lab results indicate an INR of 2.3, reflecting adequate anticoagulation levels with warfarin, yet the atrial fibrillation still potentially contributed to this embolic event. The patient's blood glucose is 180 mg/dL, slightly elevated, which necessitates careful monitoring and potential adjustment of her diabetic management to prevent further complications.

As the team discusses the therapeutic approach, they decide to initiate blood pressure management with intravenous antihypertensives to lower the risk of hemorrhagic transformation while maintaining cerebral perfusion. The patient's condition remains stable, but the persistent headache and gradual increase in respiratory rate to 26 breaths per minute raise concerns about worsening cerebral edema. This necessitates frequent neurological assessments and consideration of interventions such as mannitol administration or hyperosmolar therapy to mitigate increased intracranial pressure. The focus remains on stabilizing the patient and preventing secondary complications while planning for rehabilitation to address the neurological deficits observed.

Section 2

As the medical team continues to monitor the patient, they notice a subtle change in her status. Despite initial stabilization, the patient's headache intensifies, and she becomes increasingly restless, signaling possible complications. Repeat neurological assessments reveal a slight decline in her Glasgow Coma Scale (GCS) score from 14 to 12, indicating a reduction in her level of consciousness. Her pupils remain equal and reactive, yet there is a new onset of anisocoria, with the left pupil slightly larger than the right, suggesting potential worsening cerebral edema or impending herniation.

In response to these concerning signs, the healthcare team decides to implement a more aggressive approach to managing intracranial pressure. Mannitol is administered intravenously, and the patient's head is elevated to 30 degrees to promote venous drainage. Serial CT scans are ordered to assess for any progression of cerebral edema or development of hemorrhage. Simultaneously, the patient's respiratory rate increases to 30 breaths per minute, and her oxygen saturation begins to drop to 90% on room air, necessitating supplemental oxygen therapy and potential consideration for non-invasive ventilation support.

Repeat imaging confirms an increase in cerebral edema but no evidence of hemorrhagic transformation. The medical team collaborates with neurology and intensive care specialists to re-evaluate the treatment plan, focusing on optimizing cerebral perfusion pressure and preventing further neurological deterioration. The patient's worsening respiratory status prompts further investigation into potential pneumonia or aspiration events, given her compromised swallowing ability and slurred speech. The team initiates aspiration precautions and considers the need for swallow evaluation to prevent further respiratory complications. The evolving situation underscores the importance of vigilant monitoring and timely intervention as the patient's condition presents new challenges in her recovery journey.

Section 3

As the healthcare team continues to address the patient's evolving condition, they focus on her response to the interventions initiated for managing increased intracranial pressure and her respiratory distress. Over the next few hours, the patient's vital signs show mixed responses to treatment. Her heart rate stabilizes at 86 beats per minute, but her blood pressure remains elevated at 160/95 mmHg, likely a compensatory response to maintain cerebral perfusion. The administration of Mannitol seems to have a partial effect, as her Glasgow Coma Scale (GCS) score remains at 12, with no further decline. However, her anisocoria persists, and intermittent episodes of confusion and restlessness suggest continued cerebral edema.

Respiratory assessment reveals persistent tachypnea with a respiratory rate of 28 breaths per minute, despite supplemental oxygen therapy. Her oxygen saturation marginally improves to 93% with 2 liters of oxygen via nasal cannula, but auscultation reveals coarse crackles at the lung bases, raising concerns about fluid accumulation or aspiration pneumonia. The decision is made to initiate non-invasive positive pressure ventilation (NIPPV) to better support her respiratory efforts and improve alveolar ventilation.

In parallel, laboratory results indicate a mild leukocytosis, with a white blood cell count of 12,500/mm³, supporting the suspicion of an infectious process. A chest X-ray is ordered to further evaluate for potential pneumonia, while blood cultures are drawn to rule out bacteremia. The need for a swallow evaluation becomes more pressing, as the risk of aspiration events remains high. The multidisciplinary team, including speech therapy, is called to provide a comprehensive assessment and develop a tailored plan to mitigate further respiratory complications. This unfolding scenario highlights the interconnected nature of her neurological and respiratory status, emphasizing the need for continuous reassessment and a dynamic approach to her care.

Section 4

As the healthcare team continues to monitor the patient's condition, a new set of diagnostic results provides crucial insights. The chest X-ray confirms the presence of bilateral infiltrates at the lung bases, consistent with aspiration pneumonia. This finding correlates with the auscultation of coarse crackles and the patient's persistent tachypnea. In response to these new developments, the team initiates antibiotic therapy targeting common respiratory pathogens, starting with broad-spectrum coverage. The initiation of NIPPV appears beneficial, as subsequent arterial blood gas analysis reveals an improvement in her partial pressure of oxygen (PaO2) to 78 mmHg, although her partial pressure of carbon dioxide (PaCO2) remains elevated at 48 mmHg, indicating persistent respiratory acidosis.

The patient's neurological status, however, raises additional concerns. Her episodes of confusion become more frequent, and she exhibits occasional myoclonic jerks, suggesting increased irritability of the central nervous system. A repeat CT scan of the brain is ordered to assess for any progression of cerebral edema or new ischemic changes. In conjunction with these developments, the team decides to adjust the dosing of Mannitol and consider adding hypertonic saline to optimize osmotic therapy, aiming to reduce intracranial pressure more effectively. The neurology team is consulted to evaluate the need for further neuroprotective strategies, including the potential use of anticonvulsants if seizure activity is confirmed.

The evolving clinical picture necessitates a coordinated, interdisciplinary approach. The speech therapy team conducts an urgent bedside swallow evaluation, identifying significant dysphagia and recommending strict nil per os (NPO) status to prevent further aspiration risks. They suggest alternative nutrition through enteral feeding, and a nasogastric tube is placed to ensure adequate caloric intake and medication administration. The integration of these findings and interventions underscores the complexity of managing this patient’s intertwined neurological and respiratory conditions, requiring ongoing vigilance and adaptability from the healthcare team.

Section 5

Following the implementation of the new interventions, the healthcare team carefully monitors the patient's response. Over the next 24 hours, there is a notable change in the patient’s vital signs and clinical status. The patient’s heart rate stabilizes at 88 beats per minute, and her blood pressure is maintained at 130/85 mmHg with supportive medication. However, her respiratory rate remains elevated at 28 breaths per minute, and her oxygen saturation fluctuates between 90-92% on NIPPV with FiO2 set at 40%. Despite the initiation of antibiotics, her white blood cell count increases to 15,000/mm³, indicating a potential exacerbation of the infectious process or an inflammatory response.

The repeat CT scan of the brain reveals mild progression of cerebral edema but no new ischemic changes, confirming the need for ongoing aggressive management of intracranial pressure. The patient's neurological assessment shows persistent confusion and intermittent myoclonic jerks, necessitating the commencement of anticonvulsant therapy with levetiracetam while continuing osmotic therapy with adjustments to the Mannitol and the addition of hypertonic saline. The neurology team recommends close monitoring for any further signs of seizure activity or worsening neurological status.

Despite the proactive interventions, the patient develops a new complication: a rising temperature of 38.5°C, raising suspicion for systemic infection. Blood cultures are obtained to identify any bacteremia, and the antibiotic regimen is re-evaluated for potential adjustments based on culture results and sensitivity patterns. The healthcare team intensifies its efforts to manage the patient’s complex condition, ensuring all systems are closely monitored and adjustments are made as necessary to address the evolving challenges. This includes frequent reassessments and collaborative discussions to refine the care plan, aiming to stabilize the patient and prevent further deterioration.
