護理師準備給予全靜脈營養（TPN）。下列哪項護理行為是必要的？
A nurse is preparing to administer TPN. Which nursing action is essential?
- AChange the tubing every 48 hours每 48 小時更換管路
- BUse an infusion pump✓ 正解使用輸注幫浦
- CMonitor blood sugar every 4 hours每 4 小時監測血糖
- DAdminister via peripheral vein經周邊靜脈給藥
TPN 是高滲透壓溶液，必須透過中央靜脈導管（CVC）給予（D 錯誤）。為了精準控制滴數防止高血糖波動，必須使用輸液幫浦（B 正確）。管路需每 24 小時（而非 48 小時）更換以預防感染（A 錯誤）。血糖監測雖重要，但 D 的頻率視醫囑而定，並非所有病人都需固定 4 小時監測，且 B 是給藥安全的最核心設備要求。
TPN is a hypertonic solution and must be administered through a central venous catheter (CVC), so Option D is incorrect. To precisely control the infusion rate and prevent wide swings in blood glucose, an infusion pump must be used (Option B is correct). The tubing must be changed every 24 hours (not 48) to prevent infection, so Option A is incorrect. Although blood glucose monitoring is important, the frequency depends on the provider's order rather than a fixed 4-hour schedule for every client, so Option C is not universally correct, and Option B—use of an infusion pump—is the most essential safety requirement.
兩地對於 TPN 的護理標準一致，美國醫院更廣泛使用全自動調配器與專責營養諮詢團隊。
