病人正在進行氯化鉀靜脈輸注。哪項發現需要立即介入?
A client is receiving an IV infusion of Potassium Chloride. Which finding requires immediate intervention?
- ASerum potassium of 4.2 mEq/L血清鉀 4.2 mEq/L
- BReports of mild thirst主訴輕微口渴
- CUrine output of 50 mL/hr尿量 50 mL/hr
- DBurning at the IV insertion site✓ 正解靜脈穿刺處有灼熱感
— Explanation · 中文詳解 —
氯化鉀(Potassium Chloride)具有高度的血管刺激性,屬於高警訊藥物(High-alert medication)。若靜脈管路滲漏(Infiltration)或發生靜脈炎(Phlebitis),藥物會直接損害周圍組織,造成化學性灼傷或組織壞死。當病人主訴灼熱感,護理師必須立刻停止輸注並評估血管通路,這屬於優先級極高的安全護理行為。
Potassium chloride is a high-alert medication that irritates vessels. Burning at the IV site may indicate infiltration or phlebitis, and the drug can cause chemical burns or tissue necrosis. The nurse must stop the infusion immediately and assess the line; this is a top-priority safety action. The other findings are within normal limits or unrelated to acute toxicity.
✦ 台美臨床差異
在美國,KCl 輸注通常透過中央靜脈(Central line)進行,若透過周邊靜脈,濃度通常限制在 10 mEq/100 mL 以下,且必須由護理師嚴格監控輸注部位。
