Which type of thermometer is typically used for rectal temperature measurement?

The most appropriate type of thermometer for measuring rectal temperature is typically a glass thermometer. Glass thermometers have traditionally been designed with a specific shape that allows for safe and accurate insertion for rectal readings. These thermometers often have a shorter, more rounded end, which is essential for rectal use, ensuring comfort and maintaining safety during the measurement process.

While digital thermometers are also widely used for rectal temperature measurement due to their speed and ease of use, the question specifically asks for the type commonly associated with this method. It's important to note that although glass thermometers are less frequently used today due to safety concerns (such as the risk of breakage and mercury exposure), they remain a classic choice for rectal temperature measurements in specific practice settings.

Infrared thermometers and ear thermometers, on the other hand, are designed for non-invasive measurements and are not suitable for rectal use. They measure temperature from a distance or through the ear canal, respectively, and do not provide the specific measurements that rectal thermometers are intended for.
