  • AMonitor blood glucose levels every 4 to 6 hours✓ 正解
    每 4 至 6 小時監測血糖
  • BChange the IV tubing every 24 hours

Explanation · 中文詳解

靜脈全營養(Parenteral Nutrition, PN)包含高濃度的葡萄糖、蛋白質與脂質,極易滋生細菌且容易引發血糖劇烈波動。護理重點在於嚴格的無菌技術(Aseptic technique)、血糖監測以及輸液系統的維護。PN 的輸液管路更換頻率通常與脂質含量有關(一般為 24 小時),以預防導管相關血液感染(CRBSI)。

Parenteral nutrition (PN) contains high concentrations of glucose, protein, and lipids, making it highly susceptible to bacterial growth and prone to causing dramatic fluctuations in blood glucose. Nursing care focuses on strict aseptic technique, blood glucose monitoring, and maintenance of the IV infusion system. The frequency of changing PN tubing is typically related to lipid content (generally every 24 hours) to prevent catheter-related bloodstream infections (CRBSI).

✦ 台美臨床差異

台灣醫院對於靜脈營養管路更換頻率與過濾器的使用,常遵循各院感控規範,與美國 CDC 指引雖大方向一致,但在具體更換時程(如 24 小時 vs 72 小時)上,台灣各院內規可能存在差異。
