Things You'll Need
How To Take the Temperature
Have your patient lie down flat on their backs.
Add some vaseline to the end of the thermometer.
Insert thermometer in to the rectum about 1 inch deep and hold for 3 minutes to get an accurate reading.
How to Read the Thermometer
Count your dashes. Each thermometer has numbers and in between those numbers are little dashes. Each dash counts as two degrees. If your thermometer reads 100 and two dashes, your temperature would be 100.4. If your thermometer reads 98 and 4 dashes that would mean your temperature is 98.8. You get the idea.
Determine if your thermometer is a regular thermometer or a rectal thermometer.
Subtract a whole degree if your thermometer is a regular thermometer and you have your temperature.
Do not subtract anything from a rectal thermometer. It has been set to take an accurate temperature in the rectum.
