What is the standard range for normal adult rectal body temperature?

The standard range for normal adult rectal body temperature is typically recognized as being between 97.2°F to 100.8°F. This range reflects the slight variations in body temperature that can occur due to factors such as individual health, time of day, and activity levels. Rectal temperature is often considered one of the most accurate measures of core body temperature because it is less influenced by external factors compared to oral or axillary measurements.

Understanding temperature ranges is crucial in clinical settings, as it helps medical professionals assess patient health and identify possible fever or hypothermia. While variations among sources may occur, the range given in the correct answer aligns with medical standard practices for rectal temperature assessment in adults, making it the appropriate choice.
