What is the normal range for rectal temperature?

The normal range for rectal temperature is typically understood to be between 98.6 and 100.6 degrees Fahrenheit. Rectal temperatures are generally higher than oral or axillary temperatures due to the direct measurement of core body temperature. This range reflects the body's normal functioning and can vary slightly among individuals.

While other ranges provided in the choices may include some acceptable temperatures for different methods of measuring body temperature, the rectal range specified in the correct answer is recognized as the standard for that method. Specifically, 98.6 degrees Fahrenheit is commonly considered the average body temperature, with slight variability accounting for biological differences, activity levels, and time of day.
