Adorned mercurial clinical thermometer

Clinical thermometers are meant for clinical purposes. It is developed for measuring the human body temperature. It is a long narrow glass tube with a bulb containing mercury at the end. The normal human body temperature is 37˚C, which can fluctuate between the ranges 35˚C to 42˚C. Hence, the clinical thermometers range from 35˚C to 42˚C.The level of mercury tells our body temperature in ˚C. Oral temperature may only be taken from a patient who is capable of holding the thermometer securely under the tongue, which generally excludes small children or people who are unconscious or overcome by coughing, weakness, or vomiting.  If the patient has drunk a hot or cold liquid beforehand time must be allowed for the mouth temperature to return to its normal value.The armpit (axilla) temperature is measured by holding the thermometer tightly under the armpit. One needs to hold the thermometer for several minutes to get an accurate measurement. 

NOTE

Shake the thermometer down using quick sharp downward wrist motions before use. The mercury has to get down from a previous reading back into the bulb. If you don't shake the thermometer it will resulting an inaccurate reading.
