What are the different types of thermometers used to measure body temperature?

• A. Digital, infrared, and glass (mercury) thermometers
• B. Only digital thermometers
• C. Only infrared thermometers
• D. Glass (mercury) and paper thermometers

Answer: (A)

The correct answer encompasses a variety of thermometer types used for measuring body temperature, including digital, infrared, and glass (mercury) thermometers. Each type has unique features and uses that make them suitable for different situations.

Digital thermometers are widely used due to their quick and accurate readings, convenience, and ease of use. They often have a display that shows the temperature and can be used orally, rectally, or under the armpit. Their fast response time makes them particularly useful in both clinical and home settings.

Infrared thermometers, especially ear or forehead types, measure temperature without direct contact with the body. This non-invasive method is ideal for quick assessments, particularly in environments such as hospitals where time efficiency is critical. They can provide instant readings and reduce the risk of cross-contamination.

Glass (mercury) thermometers, once very common, measure temperature based on the expansion of mercury in a glass tube. While they can provide accurate results, they are less commonly used today due to safety concerns regarding mercury exposure and the risk of breakage.

Combining these three types of thermometers represents the variety of options available to accurately assess body temperature across different circumstances and preferences.
