What color are rectal thermometers typically?

  1. Black

  2. Blue

  3. Red

  4. White

The correct answer is: Red

Rectal thermometers are typically red because they are designed to stand out from other medical equipment and be easily identifiable. Black or white thermometers would blend in too much with the surrounding environment, making them more difficult to locate. Blue, although a common color for medical tools, is not typically associated with rectal thermometers. Additionally, red is often used as a universal "warning" color in the medical field, signaling to healthcare providers that extra care and attention should be taken.
