Which statement best describes the clinical features of thyroid storm?

• A. Fever, tachycardia, and CNS/CV/GI dysfunction
• B. Hypothermia and bradycardia
• C. Hypertension and confusion
• D. Fever with shortness of breath

Answer: (A)

Thyroid storm is a life-threatening surge of thyroid hormone that creates a hyperadrenergic, hypermetabolic state affecting multiple organ systems. The hallmark features reflect this widespread stimulation: a high fever from accelerated metabolism, tachycardia from sympathetic overactivity, and dysfunction across the CNS (agitation, delirium), cardiovascular system (tachyarrhythmias, potential heart failure), and gastrointestinal tract (nausea, vomiting, abdominal pain). Therefore, the statement that best captures its clinical presentation is fever, tachycardia, and CNS/CV/GI dysfunction, since it shows the characteristic multi-system involvement and the急 rise in metabolic activity. The other options don’t fit as well because they miss key elements. Hypothermia and bradycardia are opposite to the expected hypermetabolic, sympathetic state. Hypertension with confusion can occur sometimes but by itself doesn’t reflect the typical fever and rapid heart rate seen with thyroid storm, nor does it emphasize the full range of CNS, cardiovascular, and GI involvement. Fever with shortness of breath is less specific and incomplete, as shortness of breath alone doesn’t illustrate the broad CNS and multi-organ dysfunction that defines this crisis.
