個案被診斷為甲狀腺機能亢進。護理師應預期看到什麼臨床發現？

甲狀腺機能亢進（Hyperthyroidism）的核心病理生理為甲狀腺素（T3/T4）分泌過多，導致全身代謝速率大幅提升（Hypermetabolic state）。此狀態會增加交感神經系統的敏感度，進而引發心血管與神經系統的過度興奮。護理師在進行生理評估時，應重點關注其高代謝徵象，如心搏過速、體重減輕、怕熱及焦慮等。臨床思路應優先考慮代謝亢進對各器官系統的影響，心血管系統的穩定性是評估重點。

The core pathophysiology of hyperthyroidism is excessive thyroid hormone (T3/T4) secretion, leading to a markedly elevated metabolic rate (hypermetabolic state). This state heightens sympathetic nervous system sensitivity, causing overstimulation of cardiovascular and neurological systems. Nursing assessment should focus on hypermetabolic signs such as tachycardia, weight loss, heat intolerance, and anxiety. Cardiovascular stability is a key assessment focus.
