What must be documented in relation to temperature readings?

Documenting the method used to take a temperature reading is essential for several reasons. Different methods can yield different results and understanding the technique used helps provide context for the reading. For instance, oral, rectal, tympanic, and axillary measurements may each have unique norms and implications, thus the method used should be clearly noted to ensure accuracy in interpretation and to allow for appropriate follow-up.

The details related to the time of the reading, who took it, and the setting of measurement are also important aspects of patient care documentation. However, documentation of the method is crucial because it directly impacts the understanding of the temperature reading's validity and relevance to the patient's condition.
