Answer to Question 1

ANS: A
White matter in the brain consists of nerves coated with myelin sheaths, which allow nerve impulses to travel rapidly.

Answer to Question 2

ANS: D
A child who is stuporous only responds to painful stimuli and has verbal responses that are either absent or slow. A lethargic patient opens his or her eyes to loud voices and appears confused and falls asleep without continued stimulation. Obtundation is demonstrated when a person is aroused by tactile stimulation, such as gentle shaking, but does not show great interest in surroundings. A persistent vegetative state is a coma-like condition that has lasted for over 4 weeks.
