Study Questions and Answers
Q1 Intracranial hemorrhage's goal for treatment?
A Stop bleeding. Decrease icp.
Q2 Subdural hematoma?
A bleeding between covering of brain (dura) and surface of brain. Compress brain tissue , leadin to brain dead. Most
pt do not recover.
Q3 Epidural hematoma?
A covering of the brain (dura) peel away from skull (from skull fracture). Wake up and die. Changes in vital signs are
late signs.
Q4 SubArachnoid hemorrhage (SAH)?
A aneurysm of artery in brain, causing rupture. This is a type of hemorhagic stroke. Risk for repeated bleeding is 35%
within. First 14 days post first bleed. Vasospasm is a common complication of SAH. Cerebral angiogram can dx
cerebral aneurysm. A ruptured aneurysm has a risk for death of 40% , 08% disable after rupture.
Q5 Normal ICP for adult?
A less than 15mmHg. When treating high ICP, the goal is to be 20 mmHg ICP.
Q6 What is cushing's triad?
A three symptoms that indicate brian damage from high ICP. BRADYCARDIA, RESP DEPRESSION,
HYPERTENSION.
Q7 What factors increase ICP?
A suction, any stimulations.
Q8 Cerebral angiogram?
A visualize cerebral blood flow and blood vessels. Can remove clot in bv at time of process. Insertion of dye through
femoral artery. Pt lies flat. Indicated for: atherosclerosis, dissection, tumor, aneurysm, av malformation, stroke. Not
for kidney failure, bleeding issue, allergic to dye (iodine& shellfish). Cerebral angiogram can dx cerebral aneurysm.
A ruptured aneurysm has a risk for death of 40% , 08% disable after rupture.

, Q9 Av malformation?
A l connection between artery and vein without capillary bed between in brain blood vessels. Leading to high pressure
in veins (as vein is receiving blood too quick!-> weaken bv-> risk aneurysm.
Q10 WHY IS AVM BAD?
A 1 risk of aneurysm rupture. 2 enlarged avm will put pressure on surrounding brain. 3 cells that only gets oxy from
capillary bed will die.
Q11 Types of AV MALFORMATION?
A dural fistula, venous malformation, cavernoma, capillary telangiectasia.
Q12 two locations of AVM?
A BRAIN & SPINE.
Q13 treatment for avm?
A embolization - deliver glue/ obstructive materials into avm, thus, blood cant flow into avm to cause rupture.
Q14 what is used to locate what part of the brain is damaged by seizure or stroke. this combines both
neuroimaging anf neuropsychological tests?
A wada - inject barbiturate into carotid artery to shut down one brian hemisphere and evaluate the opposite
hemisphere..
Q15 How to know if a person will be allergic to angiogram dye?
A allergic to iodine and shellfish.
Q16 A pt with cerebral aneurysm is dx. What can the medical team do to secure it in preventing rupture of the
aneurysm?
A clipping , endovascular coiling.
Q17 What is the procedure of opening the skull?
A craniotomy.
Q18 What is clipping?
A clip at the neck of aneurysm to block normal blood floe from entering; thus, stop it from stretching further and
eventually rupture.
