One-liner
This episode provides high-yield review covering ethical principles of patient autonomy, the classic presentation and workup of subcortical stroke, identifying risk factors for post-operative infection in BV, managing acute gout flares, and interpreting positive exercise stress test results.
High-yield summary
- Patient Autonomy: A competent adult patient's stated wishes must be respected above all other recommendations (family, medical team, legal documents like POA), unless they are proven to lack capacity.
- Subcortical Stroke: Characterized by simultaneous weakness in both upper and lower extremities on the same side (contralateral to the stroke) due to deep brain structures/spinal tracts being affected below the cortex. HTN is the primary risk factor leading to microaneurysms/hemorrhage.
- Bacterial Vaginosis (BV): The strongest predisposing risk factor for post-operative infection following D&S CVA is often an active, non-normal vaginal flora, such as BV, indicated by a high pH (>4.5) and malodorous discharge.
- Gout Management: Acute gout flares are treated primarily with NSAIDs (if no contraindications), Colchicine, or Corticosteroids. Thiazide diuretics can precipitate gout by interfering with uric acid excretion.
- Stress Testing: Positive findings on an exercise stress test (e.g., ST segment depression) strongly suggest underlying Coronary Artery Disease (CAD).
Learning objectives
- Differentiate between patient capacity (legal) and competency (judicial).
- Recognize the classic motor deficits associated with subcortical vs. cortical strokes.
- Identify key risk factors for post-operative infection following gynecological procedures, particularly those related to vaginal flora changes.
- Understand the pathophysiology of gout flares and common precipitating medications/conditions.
- Interpret positive findings on cardiac stress testing in the context of CAD.
