SCRN EXAM REVIEW QUESTIONS AND
ANSWERS 100% CORRECT.
What are clinical s/s of ICA stroke? - ANSWER-aphasia if dominant hemisphere
involved
-neglect if non dominant hemisphere involved
contralateral homonymous hemianopsia (opposite side of stroke vision loss)
contralateral motor and sensory loss (opposite side of stroke)
conjugate ipsilateral eye deviation ( eyes towards side of stroke)
what are clinical s/s of L MCA stroke? - ANSWERaffects right side of the body
- aphasia
-right hemiparesis (affects face and arm > leg)
-right sided sensory loss
-left gaze deviation
-right visual field defects
-dysarthria
-difficulty reading
what are clinical s/s of R MCA stroke? - ANSWERaffects left side of the body
-left sided sensory loss
-anosognosia
-neglect
-left hemiparesis
-right gaze
-left visual field cut
-dysarthria
what are s/s of posterior stroke? - ANSWERmotor and sensory loss in all four limbs
-crossed findings
limba and gait ataxia
ptosis
dysconjugate gaze
nausea, vertigo,
dysphasia, dysarthria
locked-in syndrome
what is anosognosia and when will it be noticed? - ANSWERneglect or lack of self
awareness, noticed in strokes of the right parietal lobe
what are clinical s/s of ACA stroke? - ANSWERcontralateral sensory and motor loss
( leg > arm)
, lack of concern (aka abulia)
and in severe injury- suck and grasp (frontal lobe reflexes lost)
what are clinical s/s of PCA stroke? - ANSWERagnosia (inability to recognize things)
if in dominant hemisphere; Alexia (inability to read), agraphia (inability to write/spell),
prospopagnosia (inability to recognize familiar faces)
what is webers syndrome? - ANSWERinjury to the midbrain -- caused by PCA
ipsilateral oculomotor nerve palsy (CN3)
contralateral hemiparesis
s/s of PICA (Wallenbergs syndrome) - ANSWER- loss of pain or sensation to
contralateral trunk AND ipsilateral face
dysphagia, dysarthria, dysphonia
s/s of AICA (lateral pontine syndrome) - ANSWER-vertigo, vomiting, nystagmus, falling
towards side of lesion
-ipsilateral facial sensation loss, ipsilateral facial paralysis, ipsilateral hearing loss
what are s/s of cerebellar stroke? - ANSWERdysfunction of speech, tremor, ocular
findings, abnormal gait, ataxia (think a drunk person)
s/s of basilar artery stroke? - ANSWERpresents w/ mixed motor exam, dysconjugate
gaze, lethargy/altered MS
leads to -> coma, quadriparesis, ataxia, dysarthria
what is a lacunar stroke? s/s? - ANSWERsmall vessel stroke , < 15 mm infarct
what are watershed strokes? - ANSWERsmall infarcts occurring between major arterial
territories of the brain
what are watershed strokes primarily caused by? - ANSWERhypotension and hypoxia
( or shower of emboli /debris from ICA occlusion)
kernig's sign - ANSWERpositive when the thigh is flexed at the hip and knee and
extension of the knee is painful
brudzinski's sign - ANSWERsupine patient exhibits an involuntary lifting of leg when
head is lifted
signs of SAH - ANSWER"worst headache of life"- sudden onset
