Which term is used when the mouth is used to take a temperature?

• A. Orientation
• B. Oral temperature
• C. Oriented
• D. Osteoporosis

Answer: (B)

Taking a temperature through the mouth is called an oral temperature. The thermometer is placed under the tongue in the sublingual pocket with the lips closed, and the reading reflects the body's temperature. This method is common because it’s straightforward and accurate for many adults and cooperative older children. For the most reliable result, wait after eating, drinking hot or cold beverages, or smoking before taking the measurement, and avoid using the oral route if the person has mouth injuries, cannot keep the mouth closed, or is unconscious. Other terms shown in the choices relate to mental status (orientation, oriented) or a bone condition (osteoporosis) and don’t describe how temperature is measured.
