NURS 3664 Lecture Notes - Lecture 3: Physical Examination, Phantom Limb, Renal Artery
Document Summary
Plaque ruptures thrombi travel to other places in body/lodge. Common iliac artery, abdominal artery, deep femoral artery. 1 mm hg rise in systolic bp = 2-3% risk. Poor blood flow through vasculature, plaque build up. Tia transient ischemic attack spontaneously resolve w/out residual effects. Lack of oxygen, comes out of nowhere. Thrombi break off, lodges in vessels in brain, lack of oxygen to part of brain for period of time. Dislodged by blood flow or reroute of blood, bring blood back to brain tissue within 30 minutes, symptoms resolve. Symptoms depend on where clot is. Sudden numbness or weakness, typically unilateral (carotid to one side of brain, bilateral vassal artery) Sudden confusion, trouble speaking (expressive aphasia), or understanding (receptive aphasia) Sudden trouble walking, dizziness, loss of balance or coordination. Time is critical within 3 hours of onset of symptoms (with ischemic stroke) Tpa blood thinner, only works on fresh clot (not effective on fibrin)
