1. the right answer is C) universal precautions  

Blood-borne diseases are diseases that can spread through infection with blood and other body fluids. The most common examples are HIV, hepatitis B and viral hemorrhagic fever.

Diseases that are not transmitted directly by blood, but by acids or other vectors, are more commonly classified as vector-borne disease, although the causative agent can be found in the blood. Vector-borne diseases include West Nile virus and malaria.

To avoid contagion, it is enough to avoid direct contact (injury, transfusion) with contaminated blood.

2. the right answer is B) cuts and scrapes  

The skin (the largest organ) plays an important role in maintaining the health of the human body.

We talk about cuts and scratches when the skin is accidentally opened or torn off. These injuries can result from a fall, a shock against a hard object or a contact with a sharp or sharp object.

It happens to everyone to cut themselves from time to time, but some people are more prone to this type of injury than others.

3. the right answer is C) an insect bite or sting  

During the summer especially, insect bites are common. Very painful, they usually evolve without gravity in most cases. But some people then reveal an allergy. Attention, the reactions can then be serious, either at the level of the bite, or at the level of the whole organism.

4. the right answer is C) third-degree burn  

The skin is cardboard, white or brownish, insensitive (but the periphery of the burn can be painful), the hairs are burned. A deeper attack can reach the deep muscle masses and lead to infections.

The skin is burned deeply. Blood vessels and nerve endings are destroyed.

These stages require emergency care most often in hospitals. They leave the subject of this site.

5. the right answer is B) R.I.C.E.

Rice (RICE) is a method of treating soft tissue injuries that briefly means rest, snow, pressure and elevation. When used properly, the time for recovery often becomes faster and less harassment and inconvenience.

Rice is for soft tissue strains and is considered as first aid rather than a definitive cure. The goal is to reduce internal bleeding.

6. the right answer is True

A first aid kit or first aid kit is a container that contains both medications and instruments to provide first aid in case of illness or accident.

A first aid kit often has two rather antagonistic objectives: to cover the emergency: hypoglycaemia, anaphylactic shock, superinfection ... and to cover the "bobology": superficial cuts, various pains ...

7. the right answer is False.

The serious burn remains one of the most severe traumas that can undergo the human body. Depending on the extent and depth of the injury, the treatment may require various types of care. Some, such as cream application or physiotherapy, can last for many years.
