EXAM 2026 QUESTIONS AND SOLUTIONS
100% ACCURATE
◉ Subdural hematoma? 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? 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)? 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? Answer: less than 15mmHg. When treating
high ICP, the goal is to be 20 mmHg ICP.
, ◉ What is cushing's triad? Answer: three symptoms that indicate
brian damage from high ICP. BRADYCARDIA, RESP DEPRESSION,
HYPERTENSION.
◉ What factors increase ICP? Answer: suction, any stimulations.
◉ Glascow score of 5 indicate? Answer:
◉ Cerebral angiogram? 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? 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? 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.
