The correct answer is B) keep the victim warm and dry while lying down. The key principle in treating traumatic shock is to maintain the victim's body temperature and circulation. Keeping the victim warm and dry by having them lie down helps prevent further heat loss and promotes blood flow to vital organs. This is the recommended first-aid approach to stabilize someone in shock after an accident. The other options are incorrect because: A) exercise would further tax the body in a state of shock, C) applying ice would lower body temperature, and D) avoiding electrical equipment is not directly related to treating shock.
