## 題目

護理師教導一名開始服用 levothyroxine 的病人。哪一項陳述表示理解正確？

## 選項

1. 當我感覺比較不累時，我就會停藥。
2. 我會在睡前和鈣補充劑一起服用。
3. 我會在早上空腹時服用。 **✔ 正確答案**
4. 如果我錯過一天，我會服用雙倍劑量。

**正確答案: 3**

## 解析

levothyroxine 通常固定在早上空腹時服用。不應在症狀改善時停藥，且鈣會干擾吸收。錯過劑量的處理應遵循醫師或藥師的指導，而非在沒有指示下自行加倍。

## 深入解析

臨床判斷
甲狀腺補充療法是長期的且對吸收敏感。

記憶提示
Levothyroxine：空腹、固定時間。

## 臨床情境

臨床實務指引
甲狀腺藥物衛教包括固定時間服藥、監測症狀和檢驗數值，以及在指示下將有交互作用的補充劑分開服用。

注意
勿在沒有指導下突然停止荷爾蒙補充療法。
