A 52-year-old truck driver presents to your ED after being out in subzero temperatures for several hours trying to repair his truck. He is hypothermic when you use a low-reading rectal thermometer with appropriate calibration ("Thanks for getting the most accurate temperature, doc!"). His initial core temperature is noted to be 28°C. He has a pulse of 24 bpm, a BP of 70/30 mm Hg, and slow mentation. However, he is awake, and thus able to joke about a thermometer in his rectum.
Question 1 of 7:

A - Atropine.
