Final answer:
The forehead (temporal artery) temperature is measured using a forehead (temporal artery) thermometer, which employs infrared technology to detect heat emission from the temporal artery.
Step-by-step explanation:
The method used to measure the forehead (temporal artery) temperature is with a forehead (temporal artery) thermometer. This type of thermometer uses infrared technology to measure the heat emitted by the temporal artery. It is a non-invasive, quick, and typically hygiene-friendly method since it does not require contact with mucous membranes, and it largely eliminates the risk of cross-infection, which is particularly important in medical settings.
Thermometers are used to measure temperature on scales such as Fahrenheit, Celsius, and Kelvin. These scales use reproducible reference points, like the freezing and boiling points of water at standard atmospheric pressure, for comparison. A forehead thermometer typically provides a readout in either Fahrenheit or Celsius, making it easy to interpret the measurement.
