Module 6- Neurological Assessment Flashcards

1
Q

nerves carry fibres that can be separated into two parts. what are the two parts?

A

somatic and automatic

  • somatic- innervate skeletal (voluntary) muscle
  • automatic- innervate smooth (involuntary) muscle, cardiac muscle, and glands

Q

what are the developmental considerations for infants?

A
  • neurological system is not completely developed at birth
  • motor activity in newborns is under control of spinal chord and medulla
  • process of myelinization follows cephalocaudal order and proximal to distal order (head, neck, trunk and extremities)
  • born with primitive reflexes

Q

what are the developmental considerations for older adults?

A
  • aging process causes a general atrophy with steady loss of neurons in brain and spinal chord
  • causes a decrease in weight and volume with thinning of cerebral cortex, reduced subcortical brain structures, expansion of the ventricles
  • neuron loss leads to many people 65+ with loss of muscle bulk, loss of muscle tone in face, decreased muscle strength etc.
  • decreased muscle strength and impaired fine coordination
  • slowed reaction time
  • dizziness and loss of balance

Q

what is the glascow coma scale used for?

A

for patients with head trauma

  • widely used scoring system for patients with altered level of consciousness in ICU
  • GCS used to assess functional state of brain as a whole, not of any particular site in the brain

Q

what are the 3 divided areas on the glascow coma scale?

A
  • eye opening, verbal response, motor response
  • each area is rated separately and patients best response is scored numerically
  • 3 numbers are added; total score reflects brains functional level
