IV. Decide whether the first aid treatment is Right (R) or Wrong (W). 1. When someone is burned, you should place some ice on his wound. W 2. The function of cool water is to prevent and reduce swelling. R 3. We should put damp cloths on the second degree burns. R 4. We shouldn’t break the blisters, or they will make the wound infected. R

5. Sometimes, we can put oil or ointments on burns to stop the infection. W 6. We should make sure the bandage won’t stick to the skin when it is used. R 7. If burns are on the face, we should make the victim sit up. R 8. Cold water can be used in three types of burns. W

Post-reading
Answer the questions in your own words according to the passage.

1. Why should you put cold water on a burn? Because the cold water stops the burning process, stops the pain and prevents or reduces swelling(肿). 2. Why doesn’t a third degree burn hurt?

Because in a third degree burn the nerves have been damaged. If there are no nerves, there is no pain.

3. Why do you think clothes and jewellery near burns should be removed? Because bacteria from the clothes and jewellery could infect the burns. 4. If someone has a third degree burn, why might you see tissue? Because all layers of the skin have been burnt showing the tissue underneath.

Read the first aid treatments for these burns. If the treatment is right, write R. If it is wrong, write W and explain why. 1. Sam knocked over a kettle full of boiling water onto his legs. His legs became red, swollen and covered with blisters. Sam broke the blisters and poured icy water from the fridge onto the skin. ( W)

2. While ironing clothes, Miss Good accidentally touched the iron. Her wrist blistered and became watery. It hurt a lot. She put her wrist under the cold water tap and then kept placing cool, clean, damp cloths on it until it was less painful. Then she went to see the doctor. (R)

3. Mrs Casey’s sleeve caught fire while she was cooking. Her arm looked terrible but it didn’t hurt. The skin was charred. Her husband took off her blouse and picked off bits of the blouse stuck to the burn. He then placed butter on the burn and covered it with a wet bandage. ( W )

4. After an hour in the sun, Lily noticed her arms were red and hurt a bit. She went home and put them under cool running water. (R )
