Iodine can also cause an allergy. Stop using it if a rash occurs. Use bandages to keep dirt out of wounds, protect blisters, and keep the edges of cut together. They are usually only needed for one day, but can be worn longer. A bandage may hide a developing infection, so be sure to keep the bandage clean and dry.
Fever is used to help diagnose illness.
The best places to measure the body's temperature are in the mouth and rectum. Oral thermometers should be placed under the tongue with mouth closed for two to three minutes. Rectal thermometers should be used with a lubricant and inserted about one inch into the rectum for about two minutes. The mercury in thermometers is poisonous. Small children should not use them if it is possible they may bite down on the thermometer and break it.
