## 題目

一位服用鋰鹽的病人主訴嘔吐和腹瀉已兩天。護理師應給予哪一項指示？

## 選項

1. 如果錯過一次劑量，下次服用雙倍劑量。
2. 限制液體攝取直到腹瀉停止。
3. 繼續服用鋰鹽，因為腸胃道疾病不會影響藥物濃度。
4. 聯絡醫師，因為脫水可能增加鋰鹽中毒的風險。 **✔ 正確答案**

**正確答案: 4**

## 解析

嘔吐和腹瀉導致的體液和鈉流失，可能增加鋰鹽濃度和中毒風險。病人應聯絡醫師以獲得指導和可能的濃度評估。加倍劑量或限制液體攝取可能加劇中毒。

## 深入解析

臨床判斷
利用病人線索、時間點、檢驗數據和安全風險，選擇最符合鋰鹽與脫水的回應。

記憶提示
將最強的線索群與最安全的護理判斷配對。

KR vs US
NCLEX 考題獎勵基於線索的優先思考，而非孤立的回憶。

## 臨床情境

臨床實務指引
對於鋰鹽與脫水，請將完整的線索模式與病人當前的穩定性、醫囑數據和預期的護理範圍進行比較。

注意事項
當完整情境改變了優先順序或安全性時，不要僅根據單一孤立的線索選擇行動。

## 重要概念

- **鋰鹽** — 一種治療範圍狹窄的情緒穩定劑。
- **中毒** — 因藥物濃度過高或敏感性增加而產生的有害影響。
- **脫水** — 可能改變藥物濃度和組織灌流的體液不足狀態。
