Solution
The correct option is
D
Do not hold the thermometer by the bulb.
Precautions we need to take while using clinical thermometer:
Clinical thermometers should be washed after every use to avoid transfer of disease from one person to another.
Thermometer should not be held by the bulb as this will lead to expansion of mercury and the thermometer will give a wrong measurement of temperature.
Level of mercury should be along the line of sight to avoid any error while measuring the temperature.
Make sure that the mercury level is below
35
0
C
before using the clinical thermometer.
