Several months ago, a 20 year-old male suffered a spinal cord injury brought about by a snowboard trick gone wrong. The lasting effects of his injury include flaccid bowel and bladder and the inability to obtain an erection. While sensation has been completely preserved in his legs and feet, his motor function is significantly impaired. What type of incomplete spinal cord injury has the man most likely experienced? Anterior cord syndrome Brown-Sequard syndrome Central cord syndrome Conus meduliaris syndrome A toddler is displaying signs/symptoms of weakness and muscle atrophy. The pediatric neurologist suspects it may be a lower motor neuron disease called spinal muscular atrophy (SMA). The client’s family asks how he got this. The nurse will respond “This could result from playing in soil and then ingesting bacteria that is now attaching his motor neurons.” “No one really knows how this disease is formed. We just know that in time, he may grow out of it “This is a degenerative disorder that tends to be inherited as an autosomal recessive trait “This is a segmental demyelination disorder that affects all nerve roots and eventually all muscle groups as well.” The geriatrician providing care for a 74-year-old man with diagnosis of Parkinson disease has recently changed the client’s medication regimen. What is the most likely focus of the pharmacologic treatment of the man’s health problem? Maximizing acetylcholine release from synaptic vesicles at neuromuscular junctions Preventing demyelization of the efferent cerebellar pathways Increasing the functional ability of the underactive dopaminergic system Preventing axonal degradation of motor neurons
