Which of the following indicates a victim who is unconscious?

A victim who is unconscious does not show any signs of awareness or responsiveness to external stimuli. This includes not reacting to sound or touch, making it clear that they are not aware of their surroundings. A lack of reaction means that the victim is not in a conscious state and requires immediate assessment and intervention.

In contrast, if a person reacts to voice, they demonstrate some level of consciousness and responsiveness. Being aware of time and place signifies full consciousness and cognitive function. Similarly, if someone is confused but still awake, it indicates that they are conscious but may be disoriented or impaired in their ability to think clearly. Unconsciousness means there is an absence of these indicators, making the lack of response the definitive sign for identifying an unconscious victim.
