Answer:
A) Take off any clothing or debris that is on the wound. Remove any large or deeply embedded objects. Do not probe or clean the wound just yet. Your first priority should be to stop the bleeding. If disposable gloves are available, wear them. Stop the blood flow. Apply a clean, sterile bandage to the wound. To stop the bleeding, firmly press the bandage with your palm. Maintain constant pressure on the wound until the bleeding stops. Maintain pressure on the wound by wrapping it in a thick bandage or a clean cloth. Avoid applying direct pressure to an eye injury or embedded object. Apply adhesive tape to the bandage or continue to apply pressure with your hands. Don't remove the gauze or bandage. If the bleeding seeps through the gauze or other cloth on the wound, add another bandage on top of it. And keep pressing firmly on the area.
B) Allow the injured limb to rest. To help limit swelling after an injury, ice the area, use a cold pack, a slush bath, or a compression sleeve filled with cold water. Ice the affected area as soon as possible after the injury and continue to do so for 15 to 20 minutes four to eight times a day for the first 48 hours, or until swelling subsides. If you use ice, avoid using it for too long as this can cause tissue damage. Use an elastic wrap or bandage to compress the area. The best compression wraps or sleeves are made of elastic or neoprene.
When possible, elevate the injured limb above your heart to help prevent or limit swelling.
C)Treating severe burns Keep the burned person safe from further harm. If it is safe to do so, make sure the person you are assisting is not in contact with the source of the burn. Before approaching a burned person with electrical burns, make sure the power source is turned off. Do not attempt to remove clothing that has become entangled in the fire. Ascertain that the person who has been burned is breathing. If necessary, start rescue breathing if you know how.Remove any jewelry, belts, or other tight items from the burned area and neck. Burned areas quickly swell. Protect the burn. Cover the affected area loosely with gauze or a clean cloth.Expand the burned area. If possible, elevate the wound above the level of the heart. Keep an eye out for signs of shock. Symptoms and signs cool, clammy skin, a weak pulse, and shallow breathing are all symptoms.
Reduce the heat. For about 10 minutes, run cool (not cold) water over the affected area. If the burn is on the face, apply a cool, wet cloth to relieve the pain. Put a piece of ice in your mouth for a few minutes if you have a mouth burn from hot food or drink.
For minor burns: Remove any rings or other items that are too tight from the burned area. Try to do this as quickly and gently as possible before the area swells.Avoid breaking blisters. Blisters aid in infection prevention. If a blister does break, clean it gently with water and apply an antibiotic ointment. Use lotion. After the burn has been cooled, apply a lotion containing aloe vera or cocoa butter. This aids in the prevention of drying and provides relief. Bandage Bandage the wound. Wrap a clean bandage around the burn. To avoid putting pressure on burned skin, wrap it loosely. Bandaging keeps air out of the wound, alleviates pain, and protects blistered skin. Take a nonprescription pain reliever such as ibuprofen (Advil, Motrin IB, and others), naproxen sodium (Aleve), or acetaminophen as needed (Tylenol, others).
