One of the first decisions to make when faking a fever is which method to use for measuring temperature. While rectal thermometers provide the most accurate readings, they are also the most invasive and may not be suitable for everyone. Oral thermometers are more convenient and less invasive, while temporal thermometers offer a non-contact option.
If you're faking a fever for a medical professional, it's important to consider which method they are likely to use and plan accordingly. For most situations, an oral thermometer is the best choice as it strikes a balance.
