Persons said to be in a persistent vegetative state:

• A. are brain dead
• B. have no brain damage
• C. have minor brain damage
• D. have severe brain damage

Answer: (D)

Persistent vegetative state is characterized by wakefulness without conscious awareness due to severe damage to the cerebrum, while brainstem functions such as breathing and basic reflexes can remain intact. This means the person may open eyes and have sleep-wake cycles but lacks purposeful or aware responses. It is not brain dead, because some brain activity (especially in the brainstem) often persists, and it is not no damage or only minor damage—those would not explain the profound loss of conscious function with preserved basic reflexes. So the best description is severe brain damage.
