## 題目

一名使用furosemide的個案被開立口服氯化鉀20 mEq/day。哪一句話表示衛教正確？

## 選項

1. 「我會把緩釋錠壓碎，比較容易吞。」
2. 「我會用一整杯水並隨餐服用，以避免腸胃刺激；不會壓碎緩釋錠。」 **✔ 正確答案**
3. 「我會空腹服用，讓吸收最大化。」
4. 「我會把限水加嚴到每天1 L。」

**正確答案: 2**

## 解析

正確（2）：口服KCl可能造成腸胃刺激與潰瘍，應用一整杯水並隨餐服用。不可壓碎緩釋錠，避免劑量快速釋放造成嚴重腸胃潰瘍。使用利尿劑時需定期監測K+。（1）空腹會刺激。（3）危險。（4）需要足夠水分。

## 深入解析

記憶提示 口服KCl要配水和食物，緩釋錠不可壓碎。代鹽常含KCl，與ACEi/ARB/spironolactone併用需小心高血鉀。

## 臨床情境

情境 68歲女性心衰竭使用furosemide，K+ 3.4。醫囑口服KCl 20 mEq/day。門診衛教。

## 重要概念

- **口服氯化鉀** — 補充袢利尿劑或thiazide造成的鉀流失；常見緩釋劑型。
- **KCl腸胃刺激** — 有藥物性食道炎與潰瘍風險；應隨餐並配水服用。
- **代鹽** — 可能含KCl；與保鉀藥物合用會造成高血鉀。
