化學物質噴濺入眼睛後，應採取的行動為何？

核心概念：化學物質噴濺入眼睛是緊急醫療情況，可能導致嚴重的眼部損傷，甚至失明。立即且正確的處理是減輕傷害的關鍵。 為何正確答案對：選項 D 指出「用水沖洗至少 15 分鐘」。這是處理化學性眼部灼傷的標準急救措施。持續、大量的沖洗能稀釋並移除殘留在眼睛內的化學物質，防止其進一步侵蝕角膜或眼內組織。沖洗的時間長度（至少 15 分鐘）是為了確保化學物質被充分清除。 為何其他選項錯： C. 「用力揉眼睛」（Rub the eyes vigorously）會加劇化學物質對眼球表面的磨損和損傷，並可能將化學物質帶入更深層組織，應絕對避免。 A. 「立即戴上眼部繃帶」（Apply an eye bandage immediately）可能將化學物質封鎖在眼睛內，使其持續作用，延誤了關鍵的沖洗步驟，反而會造成更大傷害。 D. 「僅在視力模糊時尋求幫助」是危險且錯誤的想法。即使視力暫時正常，化學物質仍可能對眼部結構造成潛在損害，必須立即尋求醫療協助並進行沖洗。任何化學物噴濺眼部的事件都應視為緊急狀況。 臨床思路（Emergency / Safety / First Aid）：面對化學性眼部灼傷，時間就是眼角膜。護理師必須立即採取行動，以「沖洗」為首要任務，同時確保沖洗時間足夠長，並盡快尋求專業醫療協助。

Core concept: Chemical splash to the eye is a medical emergency that may cause severe ocular injury and even blindness. Prompt and correct management is critical to limit injury. Why the correct answer is correct: Option D states to flush with water for at least 15 minutes. This is the standard first-aid measure for chemical ocular burns. Continuous, copious irrigation dilutes and removes residual chemical from the eye, preventing further damage to the cornea or intraocular tissues. The duration (at least 15 minutes) ensures the chemical is sufficiently cleared. Why the other options are incorrect: A. Rubbing the eyes vigorously aggravates abrasion of the ocular surface, may drive the chemical deeper into tissues, and must absolutely be avoided. C. Applying an eye bandage immediately may trap the chemical in the eye, allowing continued exposure and delaying the critical irrigation step, thus worsening injury. D. Seeking help only if vision is blurred is dangerous and incorrect. Even if vision is temporarily normal, the chemical may still cause underlying damage to ocular structures, and immediate medical help and irrigation are required. Any chemical splash to the eye must be considered an emergency. Clinical reasoning (Emergency/Safety/First Aid): For chemical ocular burns, time is corneal tissue. The nurse must act immediately, prioritize irrigation, ensure adequate duration of flushing, and obtain professional medical assistance as quickly as possible.

化學物質噴濺入眼睛的緊急處理原則，在美國和台灣的急救指南中是完全一致的：立即、持續地用大量清水或生理食鹽水沖洗至少 15 分鐘，並盡快尋求醫療協助。避免揉眼睛和立即覆蓋繃帶也是共通的建議。此部分無顯著差異。
