一位疑似甲狀腺功能亢進的病人，護理師應預期看到哪項臨床表徵？

甲狀腺功能亢進（Hyperthyroidism）導致全身代謝率過高，交感神經活性增加。常見表現包括心搏過速（Tachycardia）、怕熱（Heat intolerance）、體重減輕及腹瀉。本題選項中，怕熱是其典型的代謝過高表現，而心搏過緩、體重增加與便秘則是甲狀腺功能低下（Hypothyroidism）的常見症狀。

Clients with hyperthyroidism exhibit signs of an increased metabolic rate, including heat intolerance, tachycardia, weight loss, and diarrhea. In contrast, constipation, weight gain, and bradycardia are characteristic manifestations of hypothyroidism, which involves a slowed metabolic state.
