Rectal is considered the most accurate method for taking a patient's temperature because it closely reflects the body's core temperature. Oral temperatures can be affected by food and drink, while axillary temperatures can be influenced by external temperature. Tympanic readings can also be impacted by the position of the thermometer in the ear. Overall, rectal temperatures are the most reliable and accurate method for obtaining an accurate measurement of body temperature.
