Thyroid storm is primarily characterized by which symptoms?

Hypothermia, bradycardia and somnolence
Fever, tachycardia and cutaneous vasodilation
Excitement, hypothermia and bradycardia
Fever, bradycardia and vasoconstriction

The correct answer is: Fever, tachycardia and cutaneous vasodilation

Thyroid storm is a severe, life-threatening exacerbation of hyperthyroidism and is primarily characterized by symptoms such as fever, tachycardia, and cutaneous vasodilation. These symptoms arise due to the excessive levels of circulating thyroid hormones, which stimulate various physiological processes. Fever is common in thyroid storm and can be quite high, resulting from increased metabolic activity. Tachycardia, or rapid heart rate, occurs as the body's metabolism accelerates, leading to heightened cardiac output as the body attempts to meet increased metabolic demands. Cutaneous vasodilation refers to the widening of blood vessels in the skin, which can lead to increased heat loss and is a response to the hypermetabolic state and elevated body temperature. This understanding of thyroid storm highlights the significant impact of thyroid hormones on various body systems, particularly how they drive metabolic functions and cardiovascular responses. Recognizing these characteristic symptoms is crucial for prompt diagnosis and management of this critical condition.
