1. Choose the right type: Oral, rectal, or temporal artery (forehead) thermometers.
2. Follow the manufacturer's instructions for placement and duration.
3. For oral thermometers:
- Place the tip under your tongue, near the back.
- Close your mouth and wait for the beep (usually 10-30 seconds).
4. For rectal thermometers:
- Lubricate the tip with petroleum jelly.
- Gently insert the tip about 1 inch into the rectum.

6. Read the temperature on the display.

Some tips:
