An adult male has a new diagnosis of Guillain-Barr syndrome. The nurse knows which of the following pathophysiological processes underlie the deficits that accompany the degeneration of myelin in his peripheral nervous system (PNS)?
 
  A)
  The destruction of myelin causes fewer Schwann cells to be produced in the client's PNS.
  B)
  The axonal transport system is compromised by the lack of myelin surrounding nerve cells.
  C)
  Unless remyelination occurs, the axon will eventually die.
  D)
  A deficit of myelin predisposes the client to infection by potential pathogens.
