The victim who has lost a lot of blood has low blood pressure and must be placed on their back, with the head lower than the level of the trunk and with the legs raised about 30 cm to facilitate the blood supply to the brain.

Bleeding represents the blood flowing from a blood vessel.

In the human body the amount of blood varies quite a lot depending on factors such as age, sex, health condition, etc. Men have more blood in the body than women even if they have the same height and weight as those men. An adult with an average weight, between 70 - 81 kg, has between 4.7 - 5.5 liters of blood and a child with a weight between 30 - 40 kg will have approximately half the amount of blood of an adult. The severity of bleeding is assessed depending on the amount of blood lost.

Thus depending on the amount of blood lost the bleeding can be:

• small (less than 500 ml);
• medium or moderate (1/3 of the amount of blood);
• large (approximately half of the amount of blood);
• lethal (more than half of the amount of blood).

The correct answer is: C
