病人正接受靜脈輸注 20 mEq 氯化鉀於 100 mL 生理食鹽水中，護理師觀察到注射部位出現紅腫。護理師的首要行動為何？
A client is receiving an intravenous infusion of potassium chloride 20 mEq in 100 mL of 0.9% Normal Saline. The nurse notes redness and swelling at the site. What should be the nurse's first action?
- AApply a warm compress to the area在該部位敷熱敷包
- BFlush the IV line with normal saline以生理食鹽水沖洗靜脈導管
- CStop the infusion immediately✓ 正解立即停止輸注
- DSlow the rate of infusion減慢輸注速率
氯化鉀具有高度刺激性，發生紅腫通常代表藥物滲漏（Infiltration）或血管外滲（Extravasation）。首要步驟為中斷輸注以停止藥物繼續進入組織，接著移除靜脈導管以減輕組織傷害，並根據藥物特性評估是否需要解毒劑或採取後續護理措施，確保病人安全。
Potassium chloride is highly irritating, and redness and swelling usually indicate infiltration or extravasation of the medication. The first step is to stop the infusion to prevent further drug from entering the tissues, then remove the IV catheter to reduce tissue injury, and assess whether an antidote or further nursing care is needed based on the properties of the medication, ensuring client safety.
美台臨床皆視氯化鉀外滲為緊急情況，需立即移除管路並評估組織完整性，避免後續壞死。
