A medical assistant must verify a sleeping toddler's core body temperature but avoid waking the child or making any direct skin contact. Which device would best meet this requirement?
Digital oral thermometer
Non-contact infrared temporal-artery thermometer
Infrared tympanic ear thermometer
Electronic sphygmomanometer
Non-contact infrared temporal-artery thermometers are held a short distance from (or lightly scanned across) the forehead and use infrared sensors to estimate core temperature, eliminating the need for the probe to touch the skin. Tympanic and oral digital thermometers both require probe contact-inside the ear canal or mouth-and thus risk disturbing the patient and require probe covers. A sphygmomanometer measures blood pressure, not temperature.
