D) Inattention
Ans: D
Feedback:
Consciousness is a state of awareness of self and environment. Any deficit in level of consciousness, from mild confusion to stupor or coma, indicates injury to either the RAS or to both cerebral hemispheres concurrently. A fully conscious person is totally aware of her or his surroundings. The earliest signs of diminution in level of consciousness are inattention, mild confusion, disorientation, and blunted responsiveness. With further deterioration, an individual under delirium becomes markedly inattentive and variably lethargic or agitated. Persons who cannot be fully aroused are obtunded, and those who remain in a sleep-like state are stuporous.
