A driver had been crouching for a long time while changing a vehicle’s wheel. After suddenly standing up, the driver grabs the head, loses consciousness, and falls. What should be done?

Choose an answer to check yourself.

Answer and explanation

Correct answer: Raise the driver’s legs.

Explanation

Standing up abruptly after squatting for a long time makes blood pool in the legs, the brain briefly gets too little blood, and the person faints. Raising the legs of the lying victim helps blood return to the head. Sitting him up makes it worse, and splashing water or slapping the face does not restore blood flow to the brain.
