護理師照護接受全靜脈營養(TPN)的病人。哪項實驗室數值是首要監測目標?
The nurse is caring for a client receiving total parenteral nutrition (TPN). Which laboratory value is the priority to monitor?
- ASerum potassium血清鉀
- BSerum albumin血清白蛋白
- CHemoglobin血紅素
- DBlood glucose✓ 正解血糖
— Explanation · 中文詳解 —
TPN 含有極高濃度的葡萄糖(通常為 20-50% 糖水)。最常見且即時的併發症是高血糖(Hyperglycemia),也可能在滴注中斷時發生低血糖。因此,監測血糖(D)是重中之重。鉀(A)與白蛋白(B)也重要,但不如血糖波動來的頻繁且危險。血紅素(C)受 TPN 影響較小。通常每 6 小時需測一次血糖。
Total parenteral nutrition (TPN) contains high concentrations of glucose, making blood glucose monitoring the priority to detect hyperglycemia or hypoglycemia, especially if the infusion rate changes or stops. While electrolytes like potassium and nutritional markers like albumin are important, they do not pose the same immediate risk of acute metabolic instability as blood sugar fluctuations.
✦ 台美臨床差異
美國醫院多有專門的 TPN Team;台灣則多由臨床護理師依醫囑執行,且對 Accu-check(床邊血糖)的頻率有嚴格規範。
