Answer 1

Answer: (A), (B)

The correct options are
A Do not hold the thermometer by the bulb.
B Level of mercury should be along the line of sight.

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.
