WSU Nur 2030 Pathophysiology Nervous System Disorders
Questions With Complete Solutions
absence seizure Correct Answers short loss of consciousness,
5-10 seconds, vacant expression/rapid blinking, frequently seen
in children
aculalia Correct Answers forgetting how to calculate
alzheimers disease Correct Answers progressive dementia -
widespread death of cerebral cortex/hippocampus neurons,
affects short term memory first
astrocytoma Correct Answers slow growing, infiltrative
gliomas that form cavities (pseudocysts), become more
anaplastic over time
brain herniation Correct Answers increased ICP pushes the
brain out of position
cerebral edema Correct Answers increased fluid content in the
brain - leads to increased ICP
closed brain injury Correct Answers blunt trauma, skull
remains intact
common cause of hydrocephalus Correct Answers blockage of
CSF flow
common causes of spinal cord injuries Correct Answers motor
vehicle accident
, act of violence
sports injury
fall
complete lesion Correct Answers spinal cord completely
damaged - loss of sensation and function
concussion Correct Answers immediate transient loss of
consciousness accompanied by brief amnesia - recovery usually
occurs in 24 hrs
convulsion Correct Answers motor seizure that involves the
entire body
coup-contrecoup Correct Answers direct contusion at site of
external force - rebound injury on opposite side of the brain
cranial cavity components Correct Answers 80% brain tissue,
10% CSF, 10% blood
cushings triad Correct Answers systolic HTN, bradycardia,
decreased respiratory rate
cva - stroke - brain attack Correct Answers neurologic
symptoms caused by lack of blood flow to an area of the brain
due to vessel occlusion or hemorrhage
decorticate vs decerebrate posturing Correct Answers flexion
vs extension (more severe - brainstem injury)
