Because there is a constriction to prevent the indicator fluid falling to allow the maximum temperature to be read.
In 1612 the inventor Santorio Santorio became the first to put a scale on his thermometer. It was perhaps the first crude clinical thermometer as it was designed to be placed in a patients mouth for temperature taking
Precautions need to be taken while using clinical thermometer are: _ Wash the thermometer after and before using it._* _ Make sure the temperature of the thermometer is below 35 C before taking the temperature._* _ Keep the thermometer straight in the order to see the Mercury level precisely._*
If you have an old thermometer that has mercury, then the shaking makes all of the mercury flow to the bottom of the thermometer. Then, you can get a better reading. The current digital ones work differently. Thermometers used for taking people temperatures are a special kind that go up with heat but don't go down with cold. So you have to shake a thermometer before taking your temperature to make the reading go down below your own temperature. Then the thermometer can go up again to read your temperature.
The constriction prevents the mercury from returning back to the bulb when the thermometer is removed from a particular body.
A nurse waits for the mercury thread in the thermometer to stop varying because it ensures that an accurate and stable temperature reading is obtained. The mercury needs to settle to provide an exact measurement reflecting the patient's body temperature. Any movement can lead to an inaccurate reading.

Three ways of taking a vital temperature are using a digital thermometer orally, using a tympanic thermometer in the ear, or using a temporal artery thermometer on the forehead.

Shake down the thermometer before using, if the reading on the thermometer is 94.0º F or above.

The tympanic thermometer is inserted into the outer ear canal.
The four main routes for taking temperature are oral, rectal, axillary (underarm), and tympanic (ear). Oral temperature is measured by placing a thermometer in the mouth, while rectal temperature is taken by inserting a thermometer into the rectum, often providing the most accurate reading. Axillary temperature involves placing the thermometer in the armpit, and tympanic temperature is measured in the ear using an infrared thermometer. Each method has its own advantages and is chosen based on the patient's age, condition, and the required accuracy.
No, it is not necessary to stir the water before taking the temperature. Just make sure the thermometer is placed in the water and give it a few seconds to accurately measure the temperature.
?be fore taking a child temperature say I'm going to take your temperature ,with a little thermometer,.its go under your arm and it doesn't hurt you.
Putting a penny under your tongue while taking your temperature with a thermometer can alter the temperature reading. The metal of the penny may interfere with the accuracy of the thermometer, leading to an incorrect reading. It is always best to follow the manufacturer's instructions for proper use of the thermometer.
If you put the thermometer too far in, yeah.
