a. A demyelinating process must be occurring with her infant.
b. Myelin is needed to conduct the impulses, and the neurons of a newborn are not yet
myelinated.
c. The cerebral cortex is not fully developed; therefore, control over motor function
gradually occurs.
d. The spinal cord is controlling the movement because the cerebellum is not yet fully
developed.
A mother brings her 28-month-old daughter into the clinic for a well-child visit. At the
beginning of the visit, the nurse focuses attention away from the toddler, but as the
interview progresses, the toddler begins to “warm up” and is smiling shyly at the nurse.
The nurse will be most successful in interacting with the toddler if which is done next?
a. Tickle the toddler, and get her to laugh.
b. Stoop down to her level, and ask her about the toy she is holding.
c. Continue to ignore her until it is time for the physical examination.
d. Ask the mother to leave during the examination of the toddler, because toddlers often
fuss less if their parent is not in view.
