Week 6 Grand Rounds Presentation Part 1 Requirements Assigne
Week 6 Grand Rounds Presentation Part 1requirementsassigned Topic C
Present a fictional patient with the assigned medical condition (CVA/Stroke) that includes a detailed history covering the patient's subjective data (history of present illness, previous medical history, medication allergies), objective data such as vital signs and physical exam findings, and relevant laboratory or test results if applicable to medication management.
Provide a brief pathophysiology of stroke, discuss common signs and symptoms (including labs or tests if relevant), and identify barriers related to cultural, socioeconomic, or healthcare literacy issues. Propose at least one viable solution to overcome these barriers.
Describe an evidence-based medication management plan, including first-line prescribed medications with specifics on trade and generic names, typical doses, mechanisms of action, adverse effects, contraindications, and drug interactions. Include second-line medications as alternatives if allergies exist. Discuss at least one alternative therapy and set clear expectations for treatment outcomes and follow-up care.
Support the disease description with appropriate references (textbook acceptable). The treatment plan must be supported by a minimum of two scholarly sources published within the last five years, and all sources should be cited accordingly. A references section is required.

Introduction
Stroke, also known as cerebrovascular accident (CVA), is a leading cause of morbidity and mortality worldwide. It occurs when blood flow to a part of the brain is interrupted, resulting in neuronal injury and loss of neurological functions. Understanding the pathophysiology, clinical presentation, barriers to care, and appropriate pharmacologic management is essential in optimizing patient outcomes.
Fictional Patient Profile
Jane Doe, a 68-year-old woman, presented to the emergency department with sudden-onset weakness on the right side, slurred speech, and difficulty walking. She reports a history of hypertension, atrial fibrillation, and hyperlipidemia. Jane has a known allergy to penicillin and is unsure about her current medication adherence. Her vital signs upon presentation include BP 180/100 mmHg, HR 88 bpm, RR 16, and Temp 36.8°C. Physical examination reveals right hemiparesis, facial droop, and aphasia. Laboratory tests reveal elevated LDL cholesterol and an ECG confirming atrial fibrillation, which increases her risk for embolic stroke.
Pathophysiology of Stroke
Stroke occurs due to ischemic or hemorrhagic events within the brain. Ischemic strokes, accounting for approximately 87% of cases, result from an obstruction of cerebral blood flow often caused by thrombosis or embolism. Hemorrhagic strokes involve bleeding into brain tissue following vessel rupture. Blockage from emboli, typically originating from the heart in atrial fibrillation, leads to ischemia and infarction of brain tissue, emphasizing the importance of anticoagulation therapy in prevention.
Signs, Symptoms, and Diagnostic Tests
Common symptoms include sudden weakness or numbness on one side, aphasia, visual disturbances, and loss of coordination. Diagnostic tests such as non-contrast CT scans help differentiate ischemic from hemorrhagic strokes and guide treatment decisions. Blood tests assess coagulation status and facilitate management.
Barriers to Care and Cultural Considerations
Barriers include limited health literacy, cultural beliefs about illness, language barriers, and socioeconomic factors affecting access to timely care and medication adherence. For example, patients from certain cultural backgrounds may prefer traditional remedies over pharmacologic treatments, affecting compliance.
To overcome these barriers, culturally sensitive education and interpreter services should be integrated into care plans. Simplifying medication instructions and providing community resources can improve adherence and outcomes.
Medication Management Plan
First-line Medications:
- Antiplatelet agent: Aspirin (acetylsalicylic acid)
- Dose: 81-325 mg daily
- Mechanism of action: Inhibits cyclooxygenase, reducing thromboxane A2 synthesis, leading to decreased platelet aggregation
- Adverse effects: Gastrointestinal bleeding, allergic reactions
- Contraindications: Bleeding disorders, hypersensitivity
- Drug interactions: Other NSAIDs, anticoagulants
Second-line/Alternatives (if allergy to aspirin):
- Clopidogrel (Plavix)
- Dose: 75 mg daily
- Mechanism of action: Inhibits P2Y12 ADP receptors on platelets, preventing aggregation
- Adverse effects: Bleeding, thrombocytopenia
- Contraindications: Active bleeding, bleeding disorders
- Drug interactions: Proton pump inhibitors, other anticoagulants
Anticoagulation for atrial fibrillation:
- Warfarin (Coumadin)
- Dose: Individualized to target INR of 2-3
- Mechanism of action: Inhibits vitamin K-dependent clotting factors
- Adverse effects: Bleeding, skin necrosis
- Contraindications: Active bleeding, bleeding disorders
- Drug interactions: Many, including antibiotics, antiarrhythmics, and herbal products
Alternative therapy:
- Carotid endarterectomy in selected patients with significant stenosis (though not typically in acute management)
Expected Outcomes and Follow-up:
Effective pharmacologic therapy aims to reduce the risk of recurrent stroke, prevent complications, and improve neurological function. Regular follow-ups include INR monitoring for warfarin, blood pressure management, medication adherence assessments, and lifestyle modifications. Imaging studies may be repeated periodically to monitor for vascular changes.
Conclusion
Optimizing stroke management requires a comprehensive understanding of pathophysiology, tailored pharmacologic interventions, consideration of patient-specific barriers, and ongoing monitoring. Addressing socioeconomic and cultural barriers enhances adherence and improves long-term outcomes.
