When a victim is found unconscious, the first thing to do is to
Give him cold water to drink.
Arrange the victim on his side, in a comfortable position.
Ensure normal body temperature.
Clear the airway and check breathing.✓Bonne réponse
Explication
An unconscious person may have a blocked airway or absent breathing, which requires immediate recognition and action. Giving water is dangerous, and comfort, warmth, or side positioning comes only after the airway is opened and breathing is assessed.
