Question 1

intracerebral hematoma

Answer 1

frontal/temporal
^icp
contralateral hemiplegia , brain herniation

Question 2

epidural hematoma

Answer 2

arterial-quick
skull fx, mva, sports
vomiting, seizures, hemiparesis, ipsilateral dilation and cntralateral hemiparesis =temporal herniation

Question 3

subdural hematoma

Answer 3

blood between dura mater and arachnoid, venous

acute: w/in hrs of vein tearing, sx worsen w ^ICP
subacute: w/in 48hrs-2wks, ^etoh/old

Question 4

spinal shock

Answer 4

complete loss of function below injury
hypothalamus cant regulate temp, becomes room temp
resolves in 7-20 days, maybe permanent
resolution signs: hyperreflexia, spasticity, reflex bladder emptying

Question 5

autonomic dysreflexia

Answer 5

pns/sns imbalance
d/t T6 or higher injury
noxious stimulus below injury=sns response (constrict)
bradycardia and dilation above
d/t bladder/bowel distention

Question 6

autonomic dysreflexia s/s

can cause:

Answer 6

s/s:300 sbp, blurred vision

seizures, retinal hemorrhage, pulm edema, MI, death

Anterior spinal cord lesions d/t disease or trauma

Answer 7

loss of pain/temp, motor weakness; ruptured ivd, occlusion, tumor

Question 8

Central spinal cord lesions d/t disease or trauma

Answer 8

loss of pain/temp, lower motor neuron weakness (LE);

hyperextension injury

Question 9

Posterior spinal cord lesions d/t disease or trauma

Answer 9

loss of fine touch,vib, propprioception; cervical spondylosis, epidural abscess, vB12, syphilis, MS, tumor
