Final answer:
To assess for hypothermia, the EMT should check the patient's skin temperature at the forehead, as it provides a more accurate reflection of core body temperature than other areas like cheeks, abdomen, or inner wrist.
Step-by-step explanation:
To assess skin temperature for a possibly hypothermic patient, the EMT should place the back of his hand against the patient's forehead. When checking for hypothermia, it is important to touch a part of the body that is normally exposed to the environment and has a high blood flow, as the temperature in these areas can reflect the core body temperature more accurately than extremities. The forehead is preferable in comparison to the cheeks, abdomen, or inner wrist, which can provide inaccurate readings due to their respective environmental exposure and localized blood flow characteristics.
