## 題目

一位患有嚴重子癇前症的病人正在接受硫酸鎂治療。請標示出需要立即藥物追蹤的發現。

| 領域 | 發現 |
| --- | --- |
| 呼吸 | 呼吸次數降至 8 次/分 |
| 神經學 | 膝反射消失 |
| 腎臟 | 過去 1 小時尿量為 20 毫升 |
| 神經學 | 病人越來越難以喚醒 |
| 胎兒 | 胎兒基礎心率為 140 次/分，變異性中等 |
| 循環 | 血壓從 170/108 降至 148/94 毫米汞柱 |
| 治療 | 輸注連接到幫浦 |
| 通路 | 靜脈注射部位無紅腫 |

## 解析

呼吸過緩、深部肌腱反射消失、尿量減少和嗜睡加劇，這些都表示鎂離子蓄積，需要停止輸注並進行緊急評估和急救準備。

## 深入解析

快速解答
升級處理呼吸、反射、腎功能和意識惡化。

為何這是正確的
鎂離子由腎臟清除，過高的濃度會抑制神經肌肉和呼吸功能。母體評估必須促使立即行動。

簡單類比或心像
將用藥安全視為呼吸道檢傷分類：識別威脅、中斷暴露、支持生理功能並確認持久反應。

記憶點
線索、風險、行動、反應、復發檢查。

NCLEX 決策規則
選擇能預防最即時藥物相關危害的行動，同時保留重新評估和升級的空間。

為何其他選項是錯誤的
使惡化正常化、增加相互作用藥物或延遲急救的選項會使安全循環中斷。References

## 臨床情境

用藥安全審查
核實適應症、當前評估、呼吸和神經系統狀態、藥物交互作用、授權的急救措施和可衡量的後續追蹤。
