Nervous System (Chapters 36 & 37): ATI Medical/Surgical Chapters 6,7,8,10
Know terms to describe Motor Dysfunction
-Paralysis: loss of movement
-Paresis: weakness
-Plegia: stroke or paralysis
-Mono: one limb
-Hemi: both limbs on one side
-Di- or para-= both upper limbs or both lower limbs
-Quadri- or tetra: all four limbs
Understand back pain’s usual cause
Peripheral nerve injury at the spinal nerve roots
Often due to compression of nerve toot by vertebrae or the vertebral risk
Parkinson’s Disease:
Progressively debilitating disease that grossly affects motor function.
Know four primary symptoms:
o Tremors
o Muscle Rigidity
o Bradykinesia (slow movement)
o Postural instability
Symptoms occur due to overstimulation of the basal ganglia by acetylcholine
-Risk factors
o Onset of symptoms between the ages of 40 to 70
o More common in men
o Genetic predisposition
o Exposure to environmental toxins and chemical solvents
o Chronic use of antipsychotic medications
-Expected findings
o Report of fatigue
o Report of decreased manual dexterity over time
o Stooped posture
o Slow, shuffling, and propulsive gait
o Tremors/pill-rolling tremor of the fingers
o Muscle rigidity (rhythmic interruption, mildly restrictive, or total resistance
movement)
o Bradykinesia/akinesia/Masklike expression
1
o Autonomic symptoms
Orthostatic hypotension
Flushing
Diaphoresis
o Difficulty chewing and swallowing
Drooling
Dysarthria (slurred speech)
Progressive difficulty with ADLs
Mood swings
Cognitive impairment (dementia)
