Which of the following describes the correct use of a tympanic thermometer?

A medical thermometer (also called clinical thermometer) is used for measuring human or animal body temperature. The tip of the thermometer is inserted into the mouth under the tongue ( oral or sub-lingual temperature ) under the armpit ( axillary temperature ) into the rectum via the anus ( rectal temperature ) into the ear ( tympanic temperature ) or on the forehead ( temporal temperature ).

A thermometer is an instrument for measuring or showing temperature. One type of thermometer is a narrow concealed glass tube containing mercury or alcohol which extends along the tube as it expands. Another type is a digital thermometer which uses electronics to measure temperature. Early thermometers from the time of Galileo measured the expansion and contraction of air. After the middle 17th century many used alcohol or mercury. In the 19th century a mechanical thermometer …

Some manufacturers use galinstan a liquid alloy of gallium indium and tin as a replacement for mercury. The typical "fever thermometer " contains between 0.5 and 0.3 g (0.28 and 0.17 drachms) of elemental mercury.
