## 題目

一位服用呋喃妥因 (nitrofurantoin) 治療膀胱炎的個案出現發燒、腰痛、嘔吐和肋脊角壓痛。哪項措施是適當的？

## 選項

1. 繼續使用相同的藥物，因為它能治療所有泌尿道感染。
2. 立即通知處方醫師，因為懷疑有腎盂腎炎，且呋喃妥因無法達到適當的腎臟組織濃度。 **✔ 正確答案**
3. 僅在睡前服用剩餘劑量。
4. 添加含有三矽酸鎂的制酸劑。

**正確答案: 2**

## 解析

新出現的全身性症狀和腰部發現提示腎盂腎炎。呋喃妥因適用於下泌尿道感染，而非腎盂腎炎或腎周膿腫。

## 深入解析

快速解答
在呋喃妥因治療期間，應升級處理上泌尿道感染的線索。

為什麼這是正確的
繼續使用治療下泌尿道感染的藥物可能會延遲腎臟感染的有效治療。

簡單類比或心像
建立藥物安全鏈：識別新的線索，將其與藥物作用機制或仿單限制連結，停止可預防的暴露，穩定個案，並驗證可測量的反應。

記憶點
藥物、緊急線索、保護措施和再評估終點。

NCLEX 決策規則
選擇能預防最直接藥物相關危害的措施，同時保留指示治療和必要的監測。

為什麼其他選項是錯誤的
繼續可疑暴露、將仿單標示的危險線索正常化、替代未經授權的劑量或延遲升級的選項，都會使個案處於風險之中。References

## 臨床情境

藥物安全審查
核實適應症、當前評估、劑量和途徑、器官功能、交互作用、緊急毒性線索、授權行動和可測量的後續追蹤。
