UPDATED ACTUAL Questions and
CORRECT Answers
Intracranial hemorrhage's goal for treatment? - CORRECT ANSWER - Stop bleeding.
Decrease icp.
Subdural hematoma? - CORRECT ANSWER - bleeding between covering of brain (dura)
and surface of brain. Compress brain tissue , leadin to brain dead. Most pt do not recover.
Epidural hematoma? - CORRECT ANSWER - covering of the brain (dura) peel away from
skull (from skull fracture). Wake up and die. Changes in vital signs are late signs.
SubArachnoid hemorrhage (SAH)? - CORRECT ANSWER - 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.
Normal ICP for adult? - CORRECT ANSWER - less than 15mmHg. When treating high
ICP, the goal is to be 20 mmHg ICP.
What is cushing's triad? - CORRECT ANSWER - three symptoms that indicate brian
damage from high ICP. BRADYCARDIA, RESP DEPRESSION, HYPERTENSION.
What factors increase ICP? - CORRECT ANSWER - suction, any stimulations.
Glascow score of 5 indicate? - CORRECT ANSWER -
, Cerebral angiogram? - CORRECT ANSWER - 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.
Av malformation? - CORRECT ANSWER - 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.
WHY IS AVM BAD? - CORRECT ANSWER - 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.
Types of AV MALFORMATION? - CORRECT ANSWER - dural fistula, venous
malformation, cavernoma, capillary telangiectasia.
two locations of AVM? - CORRECT ANSWER - BRAIN & SPINE.
treatment for avm? - CORRECT ANSWER - embolization - deliver glue/ obstructive
materials into avm, thus, blood cant flow into avm to cause rupture.
what test is used to locate what part of the brain is damaged by seizure or stroke. this test
combines both neuroimaging anf neuropsychological tests? - CORRECT ANSWER -
wada test- inject barbiturate into carotid artery to shut down one brian hemisphere and evaluate
the opposite hemisphere..
How to know if a person will be allergic to angiogram dye? - CORRECT ANSWER -
allergic to iodine and shellfish.
A pt with cerebral aneurysm is dx. What can the medical team do to secure it in preventing
rupture of the aneurysm? - CORRECT ANSWER - clipping , endovascular coiling.
