Answer: 4. helping the victim rest as comfortably as possible
Explanation:
When a person goes into shock, it is as a result of insufficient blood flowing through to the tissues due to an external event. As a result, the person might begin cold, weak and thirsty as more blood is needed in certain places.
The first aid treatment for this is to get the person as comfortable as possible so that they enter a resting mode where less blood is needed. You can also elevate their legs IF you know this will not cause more harm.
