CNS Class 11 (Shock/stroke) Flashcards
______ ______ occurs following spinal cord injures and is categorized by a loss of reflexes, bladder dysfunction and sensorimotor dysfunction below the level of injury
spinal shock
T/F neurogenic shock is temporary and patients usually recover in 24-48 hours
false, spinal shock
a _______ is an interruption of blood flow to the brain, leading to infarction of brain tissue
stroke
given a strokes similarity to heart attacks in terms of predisposing factors it is sometimes referred to as a ______ _____
brain attack
a ____ is considered a “warning stroke” occurring when blood clots block an artery temporarily
TIA (transient ischemic attack)
T/F after a TIA there is permanent injury to the brain
false
approximately 80-90% of CVA’s are ______/______ strokes
ischemic/occlusive
during the evolution of a stroke, there is usually a central core of dead or dying cells, surrounded by an ischemic band or area of minimally perfused cells called the ________ (border zone)
penumbra
_______ stroke is approximately 10-20% of all CVA’s
hemorrhagic
a hemorrhagic stroke is an ______ caused by rupture of supplying vessels
infarction
T/F hemorrhagic strokes have a very high fatality rate
true
severe headaches, possible vomiting, rapid onset of neurological signs associated with location of brain damage are all symptoms of a _______ stroke
hemorrhagic
_______ shock, refers to hypotension and bradycardia caused by peripheral vasodilation d/t interruption of the descending sympathetic tracts post severe CNS damage (T6 or above)
neurogenic
_________ shock can vary greatly (up to 4-5 weeks) tx in the first 7 days is focused on keeping the MAP high enough to ensure spinal cord perfusion
neurogenic
T/F the value of massage therapy during the neurogenic shock stage is questionable and only allowed with MD approval
true
