Read the following passage and answer the questions that follow : When boiling milk scalded Radha’s forearm, her mother-in-law lavishly applied ghee to the wound and wrapped a tight bandage around it. By the next day, the forearm was swollen and she was in severe pain. She then developed high fever, and four days later, was admitted to the Fortis Hospital in Noida, near Delhi, in a feverish state. She was in hospital for a month and had to undergo plastic surgery.Her mother-in-law had made a common mistake-she relied on an old prescription. First aid treatment has come down from generation to generation, and many of our mothers’ remedies are no longer recommended. Take a look at your first-aid kit; bandages, some gauze, painkillers, a tube of anti-bacterial cream, may be iodine or hydrogen peroxide. We are all familiar with these supposedly tried-and-true remedies.They may be tried, but they are not all true. “So many of us still follow traditional remedies like applying hydrogen peroxide on an open wound,” says Dr Asif Ali, head of Fortis Hospital’s emergency medicine department. “But this and other common remedies do more harm than good.” After years of research, experts are finding that your standard first-aid response sometimes may be the worst thing you can do to update your first-aid kit.When the skin is not broken, it’s hard to bear iodine for killing bacteria. That’s why doctors use it to clean an area before surgery. But if there’s a cut, says Dr Mahesh Joshi, Head of the department of emergency medicine, Apollo Hospitals, Hyderabad, full-strength iodine, hydrogen peroxide and rubbing alcohol can prove toxic to the exposed tissue, impending healing. The chemical reaction that occurs when hydrogen peroxide hits the skin isn’t only cleaning the wound- it’s killing healthy cells. This stuff hurts because it’s wiping out healthy tissue.Applying iodine on cuts and wounds kills bacteria, says Dr Mahesh Joshi, but it won’t clean the wound. “Iodine doesn’t protect good skin tissue, it harms it.” Instead of cleansing a wound: “The best way to rid of dirt and germs is to wash the wound out with water,” says Dr Asif Ali. Put the wound under a tap, or a hand shower. Flush it with water to clear it of all waste. If you are worried about the bandage sticking to the wound, consider using an antibacterial ointment like Soframycin to keep the area lubricated. In this way we should be very cautious in using traditional way of first aid.1. How according to Dr Asif should a wound be cleaned as a first-aid ?2. Which ointment for lubrication has been mentioned in the passage ?3. Which mistake caused Radha’s hospitalization and plastic surgery?4. How does hydrogen peroxide hurt the wound in the cleaning process ?5. What can prove toxic to exposed tissue ?
