|Test to be performed - Measuring body temperature orally
Temperature by mouth can be determined by utilizing a traditional mercury-filled thermometer or digital thermometer that uses an electronic probe cover to measure body temperature.
- When taking an oral temperature, shake down the glass mercury thermometer to 96°F (35°C) or below. This procedure is not needed for digital thermometers.
- Have the patient place the thermometer under one side of the back of the tongue as pictured to the right.
- Instruct the patient to close both lips around the thermometer and breath through his/her nose.
- Wait 3-5 minutes for a mercury thermometer or until the digital beep sounds if using a digital device.
- If using a mercury thermometer, reinsert the thermometer after the initial reading for 1 minute and read again. If the temperature is still rising, repeat this procedure until the reading remains stable.
|Clinical notes - The clinician should note that hot and cold liquids consumed by patients within the past 15 minutes can adversely affect thermometer readings.
