What is the correct process for taking a patient's temperature orally?

The correct process for taking a patient's temperature orally involves placing the thermometer under the tongue and waiting until it beeps. This method is accurate as the tongue provides a good site for measuring the body’s core temperature, which reflects the internal temperature more effectively than other sites.

When using an oral thermometer, it's crucial to ensure that the patient has not consumed anything hot or cold, smoked, or exercised right before the measurement because these activities can affect the accuracy of the reading. Once placed under the tongue, it is important to keep the mouth closed to allow for an accurate reading, and the thermometer typically beeps to indicate that it has finished measuring the temperature.

Other methods mentioned do not provide an accurate measurement of the body's core temperature. Using a thermometer in the armpit is referred to as an axillary temperature reading, which is typically less accurate. Placing the thermometer in the ear is a method for taking a tympanic temperature, not an oral one. Holding a thermometer next to the patient’s mouth does not provide an actual measurement, as it requires being under the tongue for proper readings. Thus, placing it under the tongue is the standard method for obtaining an oral temperature.
