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.Based on this, we can know his burn belongs to second dgree burns.Based on Para5, for first degree burns and second degree burns,first place burns under gently running water for about ten minutes. And then place cool,clean,wet cloths on burns until the pain is not so bad. Based on Para5 if the burns are second or third degree burns, it is vital to get the victim to the doctor or hospital at once.14Tell right from wrong;Exercise 2Indicate where it is wrong if it is wrong;Indicate why it is wrong;Correct 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.Based on this, we can know his burn belongs to third dgree burns.Based on para 5, he was right to take off her wife’s blouse but he shouldn’t have picked off bits of blouse off the burn. Because if you pull the clothes that are struck to the burn, you would pull the tissue under clothes off too. This would cause more damage to the burn.He shouldn’t have placed butter on the burn because it would prevent the heat from escaping and cause infection.He shouldn’t have put a wet but a dry bandage on the burn.15Tell right from wrong;Exercise 2Indicate where it is wrong if it is wrong;Indicate why it is wrong;Correct 4. After an hour in the sun, Lily noticed her arms were red and hurt a bit.

Putting the sunned arms under running water can stop the burning process, prevent the pain becoming unberable and reduce swelling.16Disscuss with your partner and summarize how to give correct first aid treatment for first degree burns, second degree burns and third degree burns.17How to give correct first aid treatment for first degree burns?clothing and jewellery that aren’t stuck to the burn.burns with cool or cold water but not icy water for about ten minutes.cool, clean, wet cloths on the buens until the pain isn’t so bad.the burned area gently.Don’t rub.The burned area with a dry,clean bandage and hold the bandage in place Don’t remove clothing and jewellery stuck to the burn.
