As indicated in paragraph 2-3i, the location where the temperature is taken causes a slight difference in a patient’s temperature reading.
Suppose you were to measure a patient’s oral, axillary, and rectal temperature at the same time. The axillary temperature reading would be about 1º F (0º.6 C) lower than the oral temperature reading while the rectal temperature reading would be about 1 ºF (0.6º C) higher than the oral temperature reading (figure 2-6).
NOTE: This example is given in order to illustrate a point. You do not take a patient’s temperature three different ways at the same time.
