Question

Among the following: what should not be done while or before using a clinical thermometer?

Answer 1

Hint: A medical thermometer (also known as a clinical thermometer) is a device that measures the temperature of a person or an animal. The thermometer's tip is put into the mouth, under the tongue (oral or sublingual temperature), under the armpit (axillary temperature), into the ear (tympanic temperature), or on the forehead (facial temperature) (temporal temperature).

Complete step-by-step solution:
The mercury level should be below \[{35^o}C\](${94^o}F$), because a clinical thermometer's minimum reading is\[{35^o}C\], thus it must be at the lowest level to measure the correct temperature. If we wash the thermometer in hot water, the mercury expands due to the heat provided by the hot water and rises to a higher temperature. If the water is really hot, the thermometer may be damaged. As a result, it must not be done. It must be handled with caution since it is composed of glass and contains dangerous mercury. If we hold the bulb in our hand, the thermometer will absorb heat from our hand and provide an incorrect reading; thus, we should not hold the bulb in our hand.
The thermometer is rinsed with room temperature water. It jerked a few times. We see that the jerks lower the mercury level. We make sure it's below 37 degrees Celsius (98 degrees Fahrenheit), which is the typical human body temperature. To acquire a reading on the thermometer, the thermometer is placed under the mouth or under the arms. In order to observe the accurate reading, the thermometer is then held close to the eye.

Note:We need a specific form of thermometer for other applications since clinical thermometers can't be used to monitor temperature outside of the human body. A laboratory thermometer, sometimes known as a lab thermometer, is a device that is used to measure temperatures other than those of the human body. The temperature ranges from -10 to 110 degrees Celsius. Laboratory thermometers are used in the laboratory to determine the boiling point, freezing point, and temperature of various substances. A laboratory thermometer may be used to assess the temperature of a solvent, but not a clinical thermometer.
