護理師給予治療甲狀腺功能亢進的藥物。首要評估項目為何？
A nurse is administering a medication for hyperthyroidism. Which is the priority assessment?
- AWeight體重。
- BBlood glucose血糖。
- CHeart rate✓ 正解心率。
- DRespiratory rate呼吸頻率。
治療甲狀腺功能亢進的藥物（如 Methimazole 或 PTU）旨在抑制甲狀腺素合成。甲狀腺亢進的臨床特徵包括心跳過快（Tachycardia）、心悸與震顫，因此評估心率是評估藥物療效與安全性的首要指標。若心率減慢至正常範圍，顯示藥物有效；若心率過慢或出現心律不整，可能表示劑量過高或副作用，需即時調整。
Antithyroid medications used to treat hyperthyroidism (such as methimazole or PTU) act by inhibiting thyroid hormone synthesis. The clinical features of hyperthyroidism include tachycardia, palpitations, and tremor; therefore, heart rate is the most important assessment parameter for both therapeutic efficacy and safety. A decrease in heart rate toward the normal range indicates the medication is effective, whereas excessive bradycardia or new arrhythmias may indicate overdose or adverse effects requiring prompt adjustment.
