Final answer:
Ice packs should be placed on the wrists, ankles, armpits, forehead, and neck to cool a patient experiencing a thyroid storm, as these areas have large blood vessels close to the skin that facilitate heat exchange.
Step-by-step explanation:
The placement of ice packs in a patient experiencing a thyroid storm is crucial to help manage the hyperthermia associated with this condition. The correct placement of the ice packs should be at key areas where large blood vessels are close to the skin surface for efficient heat exchange. Therefore, option C) On the wrists, ankles, armpits, forehead, and neck is the most appropriate as these areas allow for the cooling of blood circulating through the major arteries and veins, helping to lower the patient's core temperature. This approach is part of supportive care for thyroid storm, which is a severe and life-threatening health emergency that requires rapid medical intervention.
