## 題目

護理師檢視一位服用 digoxin 個案的檢驗結果。哪項結果會增加 digoxin 中毒的風險？

## 選項

1. 血清鈉 140 mEq/L。
2. 血清鎂 2.0 mg/dL。
3. 血清鉀 3.1 mEq/L。 **✔ 正確答案**
4. 血清鈣 9.2 mg/dL。

**正確答案: 3**

## 解析

低血鉀會增加心肌對 digoxin 的敏感性，並提高中毒風險。所列出的鈉、鈣和鎂數值並非此情境中的關鍵風險線索。護理師應在給予 digoxin 前識別出低血鉀。

## 深入解析

臨床判斷
運用個案線索、時間點、檢驗數據及安全風險，選擇最符合 Digoxin 與低血鉀的回應。

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，而非單獨的記憶。

## 臨床情境

臨床實務指引
針對 Digoxin 與低血鉀，將完整的線索模式與個案當前的穩定性、醫囑數據及預期的護理範圍進行比較。

注意
當完整情境改變了優先順序或安全性時，切勿僅根據單一線索選擇行動。

## 重要概念

- **Digoxin** — 一種強心苷，用於改善心肌收縮力及控制某些心律不整。
- **低血鉀** — 血清鉀濃度過低，可能增加心律不整的風險。
- **中毒** — 因藥物作用過強或蓄積所引起的傷害性效應。
