一位35歲女性正透過打在右手背的周邊靜脈留置針接收靜脈廣效抗生素。在早晨巡房時，她抱怨打針部位有輕微的緊繃與不適感。護理師評估該注射部位，發現它顯著地腫脹（水腫）、肉眼可見的蒼白，且觸摸起來明顯感覺冰冷。基於這些具體的臨床發現，強烈指示了哪一種靜脈注射併發症？且立刻的行動為何？
A 35-year-old female is receiving intravenous broad-spectrum antibiotics via a peripheral IV catheter placed on the back of her right hand. During morning rounds, she complains of mild tightness and discomfort at the site. The nurse assesses the insertion site and finds it significantly swollen (edematous), visibly pale, and distinctly cool to the touch. Based on these specific clinical findings, which intravenous complication is highly indicated and what should be the immediate action?
- APhlebitis; the nurse should apply a warm compress and continue the infusion closely.靜脈炎；護理師應施加熱敷並密切繼續輸注。
- BExtravasation of a vesicant; the nurse should forcefully aspirate the tissue and inject a chemical antidote directly into the pale swollen area.發泡劑外滲；護理師應強力抽吸組織並將化學解毒劑直接注入蒼白腫脹區域。
- CNormal venous expansion; the nurse should simply slow the infusion rate to reduce the tightness.正常靜脈擴張；護理師只需減慢輸注速率以減輕緊繃感。
- DInfiltration; the nurse should immediately stop the infusion, remove the IV catheter, and elevate the extremity.✓ 正解浸潤；護理師應立即停止輸注、拔除靜脈導管並抬高患肢。
本題測驗靜脈輸液治療（IV Therapy）中最常見的併發症區分。當靜脈點滴針頭意外滑出或刺穿靜脈管壁時，非刺激性的液體會漏入周邊皮下組織，這在醫學上稱為「浸潤（Infiltration）」。由於液體積聚，組織會呈現浮腫（Edema/Swelling）；且因為皮下的水分壓迫了微血管，加上常溫點滴液的冷卻效應，該部位皮膚會經典地表現為「蒼白（Pale）」與「冰冷（Cool to touch）」。這與「靜脈炎（Phlebitis）」恰好完全相反——靜脈炎因血管發炎，會導致患部「發紅發黑、發熱（Warm）、並形成一條堅硬的紅線」。一旦確認為浸潤，該靜脈通路即宣告報廢，護理師的首要行動是『立刻停止輸注並拔除針頭（Remove the IV）』，接著將手部抬高以利積水吸收，然後更換部位重新打針（選項D正確）。選項A的靜脈炎判斷錯誤。選項B發泡性藥物外溢（Extravasation，如化療藥物導致的深層組織腐蝕壞死）通常伴隨劇痛、發紫或水泡，且普通抗生素多屬 Infiltration 而非高度毀滅性的 Extravasation。選項C忽視了點滴已不在血管內的客觀現實。
The assessment findings of swelling, pallor, and coolness indicate IV infiltration, where non-vesicant fluid leaks into surrounding tissue. The nurse must immediately stop the infusion and remove the catheter to prevent further tissue damage, then elevate the extremity to promote fluid absorption.
「冰的、腫的、白的 = 漏針 (Infiltration)」「熱的、紅的、一條線 = 靜脈炎 (Phlebitis)」。這是全球幾乎所有病房護理師每天打點滴的反射神經與國考必考題。
