In what scenario would an axillary temperature reading be inaccurate?

An axillary temperature reading can be inaccurate if the thermometer is not properly positioned. Proper placement is crucial for obtaining an accurate temperature because the axilla (armpit) is not as stable a temperature site as oral or rectal measurements. If the thermometer is not fully inserted into the armpit or if there is too much exposure to the outside air, it can lead to a significant misrepresentation of the body’s true internal temperature. A poorly positioned thermometer may not reflect the core temperature, which diminishes the reliability of the measurement.

This emphasizes the importance of correct technique when measuring temperature in this location, as even slight misplacement can yield misleading results.
