When measuring rectal temperature, which type of thermometer is typically used?

• A. Glass thermometer
• B. Digital thermometer
• C. Infrared thermometer
• D. Mercury thermometer

Answer: (B)

Using a digital thermometer for measuring rectal temperature is the preferred method due to its accuracy and ease of use. Digital thermometers provide quick readings and are designed to be safe for this specific purpose, as they often have a flexible tip and a shorter length compared to other types, which helps ensure comfort and safety during the process. Digital thermometers also eliminate the risks associated with glass or mercury thermometers, such as breakage or mercury exposure, which are particularly important considerations in a clinical setting. They can also record higher temperatures accurately, which is critical when assessing for fever or other medical conditions. In contrast, glass thermometers, while they can be used, are less common due to safety concerns and the potential for breakage. Mercury thermometers are generally not recommended anymore due to toxicity risks. Infrared thermometers, while excellent for non-invasive measurements, are typically not used for rectal temperature readings as they are designed for surface temperatures or tympanic readings.
