Which of the following is NOT a symptom of a thyroid storm?

In the context of a thyroid storm, which is a life-threatening condition characterized by an extreme overproduction of thyroid hormones, the symptoms typically include tachycardia (rapid heart rate), hypertension (high blood pressure), and confusion or altered mental status.

Tachycardia and hypertension are common manifestations due to the increased metabolic demands and heightened adrenal responses associated with excessive thyroid hormone levels. Confusion can occur due to the metabolic derangements and the impact of hyperthyroidism on the brain.

Low blood pressure is not a typical symptom of a thyroid storm. In fact, one of the characteristic features of a thyroid storm is elevated blood pressure rather than low. Thus, identifying low blood pressure as not being a symptom accurately reflects the physiological responses seen in this critical condition.
