An 84-year-old woman with history of atrial fibrillation presents to the emergency department with right arm weakness that began acutely 2 hours earlier, accompanied by dizziness and nausea. She takes warfarin, digoxin, and diltiazem. Vital signs are temperature 37 degrees Celsius, blood pressure 180/100 mm Hg, pulse 120-150 and irregular, respiratory rate 16 per minute, SpO2 98% on 4L oxygen by nasal cannula. Head CT shows no signs of bleed. What is the most likely etiology of her stroke

hytertention. she's on warfarin which makes blood clot less likely. her BP is extremely high. I'd go with that.

to increase speed you need to decrease frictiona dn drag hense why sprinters wear tight track suits to keep tight against there skin to keep away from wind and decrease the amount of drag you are carrying.a swimmer will wear the tightest swim suit they can possibly fit into (i was a size 28 swim suit at meets i wore a   size 23) why? because the tighter your clothing is the less drag and negative force you have. the heavier the clothe the slower and more wind gets caught. cotton tends to hold onto alot of sweat and water making it slower then say a track suit (no idea what they are made of but they are really comfy around your answer )

hope this !
