護理師執行靜脈管路繼發輸注（Piggyback）。下列哪些做法是正確的？（選所有適合的）
A nurse is administering a piggyback medication to a client. Which actions are required to ensure safety? (Select all that apply.)
- AEnsure the primary bag is lower than the secondary bag✓ 正解確保主袋低於繼發袋
- BVerify the compatibility of the medication with the primary IV solution✓ 正解確認藥物與主要靜脈輸注溶液的相容性
- CClamp the secondary tubing after the infusion is complete輸注完成後夾緊繼發管路
- DPerform the three checks and five rights of medication administration✓ 正解執行藥物給藥的三查五對
- EFlush the intravenous line with heparin before starting the piggyback開始繼發輸注前以肝素沖洗靜脈管路
繼發輸注重點在於重力原理，繼發瓶需高於原輸液瓶以利滴入。藥物相容性確認是預防藥物沈澱的核心安全指標。此外，給藥程序必須遵守三讀五對原則。C 選項錯誤：結束後應關閉繼發線路閥門；E 選項錯誤：繼發液體直接注入原管路即可，不需頻繁使用肝素沖洗。
Secondary infusions rely on the principle of gravity: the secondary bag must be hung higher than the primary IV bag to allow it to flow in. Confirming medication compatibility is the core safety measure for preventing drug precipitation. In addition, the administration process must follow the three-checks and five-rights principle. Option C is incorrect: after completion, the clamp on the secondary tubing should be closed. Option E is incorrect: secondary fluid is infused directly through the primary line, and frequent heparin flushes are not required.
美國醫院多廣泛使用輸液幫浦，台灣部分醫院仍依重力滴注計算，但護理技術大同小異。
