護理師照護一位甲狀腺機能低下病人，預期會發現哪項表現？

甲狀腺機能低下（Hypothyroidism）導致全身代謝率下降，臨床表現以「低代謝」為特徵。常見症狀包括畏寒（因產熱減少）、體重增加（因代謝變慢）、便秘（因腸蠕動減慢）、嗜睡、皮膚乾燥及心跳過慢（Bradycardia）。選項B（畏寒）是此病最典型的生理反應。其餘選項如體重減輕、心跳過快、食慾增加均為甲狀腺機能亢進（Hyperthyroidism）的臨床表徵。

Hypothyroidism produces a generalized hypometabolic state. Findings include cold intolerance (reduced heat production), weight gain, constipation, lethargy, dry skin, and bradycardia. Weight loss, tachycardia, and increased appetite are typical of hyperthyroidism, not hypothyroidism.
