What is the normal range for rectal temperature?

1. 96.6 - 99.7 F

2. 96.6 - 98.6 F

3. 97.2 - 100.1 F

4. 98.6 - 100.6 F

The correct answer is: 96.6 - 99.7 F

The normal range for rectal temperature is generally accepted to be around 98.6 to 100.6 degrees Fahrenheit. This range reflects the typical variation observed in body temperature when measured rectally, which is considered one of the most accurate forms of temperature measurement due to its close proximity to core body temperature. While the option indicates a slightly broader span from 96.6 to 99.7 degrees, this does not account for the more specific and accepted range that rectal readings typically fall within. The ideal normal range for rectal temperature is specifically more focused around the higher end, recognizing that these readings are generally higher than oral or axillary measurements. Understanding the ranges for different types of temperature readings is crucial for assessing a patient’s health, especially since temperature can be an important indicator of infection or other medical conditions.
