護理師評估甲狀腺功能亢進病患時，應觀察到哪些臨床表現？（選所有適合的）
Which assessment findings should a nurse expect for a client with hyperthyroidism? (Select all that apply.)
- ATachycardia✓ 正解心搏過速
- BWeight gain體重增加
- CHeat intolerance✓ 正解不耐熱
- DExophthalmos✓ 正解眼球突出
- EBradycardia心搏過緩
甲狀腺功能亢進（Hyperthyroidism）意指甲狀腺素（T3/T4）過量，導致全身代謝率異常升高。交感神經系統會因此變得極度敏感，引發心搏過速（Tachycardia）、熱不耐受（Heat intolerance）與產熱增加。葛瑞夫茲氏病（Graves' disease）引起的甲狀腺亢進更常見突眼（Exophthalmos）。這些生理變化的核心在於代謝過度加速，與甲狀腺功能低下（Hypothyroidism）的表現完全相反。
Hyperthyroidism refers to excessive thyroid hormone (T3/T4), causing systemic metabolic rate to rise abnormally. The sympathetic nervous system becomes extremely sensitive, producing tachycardia, heat intolerance, and increased heat production. Graves' disease — a common cause of hyperthyroidism — is also frequently associated with exophthalmos. These physiologic changes center on accelerated metabolism and are the opposite of the findings seen in hypothyroidism.
