N4 Test - Different Strokes for Different Folks

I got stoke info from this article and reduced it:

Are you ready to manage patients with acute ischemic stroke?
http://www.nursingcenter.com/prodev/ce_article.asp?tid=592119

Hemorrhagic stroke - 20% - BV in brain ruptures - blood seeps into brain

Ischemic stroke 80% - Thrombotic or Embolic

Thrombotic – 70% - plaque buildup in arteries – plaque ruptures – clot forms at site (thrombus) – occludes lumen of artery – leading cause atherosclerosis – S/Sx – over time (hours or days)

Embolic – 30% - traveling blood clot (embolus) – occludes artery in brain – leading cause A-fib – S/Sx – acute then resolving

Both – Symptoms depend on degree of blockage and location in brain.

TIAs may or may not be in history.

TIA - (same S/Sx as stroke but resolve in less than 24 h)

Brain - Two blood systems - carotid and vertebral

carotid system – face – 60% of cerebrum

S/Sx of occlusion - varying degrees

* sudden onset of sensory deficits on one-side of the body

* hemiparesis (weakness or partial one-sided paralysis)

* hemiplegia (one-sided paralysis)

* one-sided monocular vision loss

* aphasia (inability to speak or to understand what others are saying)

* dysarthria (a speech disorder involving the muscles used to speak; words are slurred, difficult to form)

* confusion.

Vertebral system - brainstem, cerebellum, and the posterior region of the cerebrum S/Sx of occlusion

* dizziness

* lack of coordination

* clumsiness

* blindness

* paralysis

* coma.

Other signs and symptoms of stroke include a sudden and severe headache, visual disturbances, and difficulty walking.
