ANSWERS 100% SOLVED.
cerebral cortex - ANSWERgray matter on the outermost section of the cerebrum and
cerebellum
composed of neuronal cell bodies

Parietal
Temporal
Occipital
Oxygen supplemental need - ANSWER> 93%
BP goal post tPA - ANSWER<180/105
Vast majority of fatal hemorrhages occur within - ANSWERthe first 12 hours
hyperthermia management - ANSWERstrict < 38.0 or 100.4
tylenol for fevers
neurogenic fevers with an early increase in temperature
after 24 hours - ANSWERcan restart antihypertensives
blood pressure goals if they did not receive tPA - ANSWERsystolic < 220
diastolic < 120
** do not want to bring BP down fast d/t risk for hypotension
Co2 is a potent vasodilator - ANSWERleads to an increase in ICP
more blood volume to brain
mild hyperventilation for low CO2 leads to lower ICP and vasoconstriction
