Question

Before using the clinical thermometer mercury level should be below:

• A. ${45}^{\circ }C$
• B. ${35}^{\circ }C$
• C. ${95}^{\circ }C$
• D. ${55}^{\circ }C$

Answer 1

Answer: (B)

${35}^{\circ }C$

The mercury level should be below ${35}^{o}C$ or ${94}^{o}F$, because minimum temperature of human body can not be below ${35}^{o}C$. Hence, it must be at lowest level to measure the temperature of human body correctly.
