When someone is burned, you should place some ice on his wound.2. The function of cool water is to prevent and reduce swelling.3. We should put damp cloths on the second degree bums.4. We shouldn't break the blisters, or they will make the wound infected.5. Sometimes, we can put oil or ointments on bums to stop the infection.6. We should make sure the bandage won't stick to the skin when it is used.7. If bums are on the face, we should make the victim sit up.8. Cold water can be used in three types of burns.Suggested answers:l.W 2.R3.R4.R 5.W 6.R 7.R 8. WStep 6 Post-readingAnswer the questions in your own words according to the passage.1. Why should you put cold water on a burn?2. Why doesn't a third degree burn hurt?3. Why do you think clothes and jewellery near burns should be removed?4. If someone has a third degree burn, why might you see tissue?Suggested answers :1 .Because the cold water stops the burning process, stops the pain and prevents or reduces swelling (月中).2.Because in a third degree burn the nerves have been damaged. If there are no nerves, there is no pain.3.Because bacteria from the clothes and jewellery could infect the burns.4.Because all layers of the skin have been burnt showing the tissue underneathStep 7 ConsolidationRead the first aid treatments for these burns. If the treatment is right, write R. If it is wrong, write W and explain why.7. 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. ()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. ()8. Mrs Casey s sleeve caught fire while she was cooking. Her arm looked terrible but it didn ft hurt. The skin was charred. Her husband took off her blouse and picked off bits of the blouse stuck to the bum. He then placed butter on the burn and covered it with a wet bandage. ( )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. ()Suggested answers:1. Wrong : Sam should not have broken the blisters because the burns could become infected. He should have poured cool water , not icy water on the burn. The correct treatment for a second degree like Sam's is in No. 2 of the exercise.2. Right .3. Wrong : Mr Casey was right to take his wife's blouse off but he should not have picked bits of blouse off the burn. This is because if you pull the material that is stuck off a third degree burn like Mrs Casey's , you should pull the tissue under the material off too. This would cause more damage to the burn. He should not have put butter on the burn because it would have stopped the heat from escaping and it might also cause the burn to become infected . He should not have put a wet bandage on the burn . The correct first aid treatment for a third degree burn is to remove clothing and jewellery near the burn but not if the clothing is stuck to the burn . Do not put cold water on the burn . Place clean , dry cloths over the damaged area . Get the person to hospital at once .4. Right.Step 8 Homework1. Get more about first aid from the newspaper, magazine or the Internet.2.
