Question 1 of 5
A nurse is explaining to parents how the central nervous system of a child differs from that of an adult. Which statement accurately describes these differences?
Correct Answer: A
Rationale: The correct answer is A: The brain of a term infant weighs less than half of the weight of the adult brain. This is because at birth, the infant brain is not fully developed and continues to grow rapidly during the early years. The brain weight increases significantly as the child grows and reaches adulthood. This statement accurately reflects the difference in brain development between a child and an adult.
Explanation for why other choices are incorrect:
B: The statement about CSF volume does not directly relate to the central nervous system differences between a child and an adult.
C: Myelinization of peripheral nerves is related to motor skills development, not specifically central nervous system differences between a child and an adult.
D: Papilledema is not a common manifestation of intracranial pressure in very young children, so this statement is incorrect in the context of the question.
