What is the normal temperature range for axillary temperature?

The normal temperature range for axillary temperature is typically between 96.6 and 98.6 degrees Fahrenheit. This range is established because axillary measurements are usually lower than oral and rectal readings due to the nature of how temperature is measured in these areas. The axilla, being an external site, is less insulated and can be influenced by environmental factors, which often results in slightly lower readings compared to the body's core temperature.

Understanding this range is important for healthcare providers and certified nursing assistants, as they must accurately assess and interpret a patient’s body temperature to spot potential health issues. If a patient’s axillary temperature falls outside of this range, it might indicate a fever or a hypothermic condition, requiring further investigation.
