Which body area has a normal temperature of 99.6 degrees Fahrenheit?

1. Axilla

2. Mouth

3. Rectum

4. None of the above

The correct answer is: Rectum

A normal temperature of 99.6 degrees Fahrenheit corresponds to readings taken from the rectum. The rectum is considered one of the most accurate sites for measuring core body temperature because it closely reflects the internal body temperature. Different parts of the body have varying normal temperature ranges due to several factors, including their proximity to internal organs and environmental exposure. For example, oral temperatures typically average around 98.6 degrees Fahrenheit, and axillary (armpit) temperatures are generally lower, reflecting less accurate measurements of core body temperature. The rectal measurement is utilized in many clinical settings, particularly for infants or when fever or illness is suspected, as it provides the most reliable indication of true body temperature.
