病人預計接受心導管檢查。哪項術前護理評估最重要？
A client is scheduled for a cardiac catheterization. Which pre-procedure nursing assessment is most critical?
- AEnsuring the client has not eaten for 8 hours確保病人已禁食8小時
- BChecking the client's current weight測量病人目前體重
- CAssessing for allergies to iodine and shellfish✓ 正解評估是否對碘及貝殼類過敏
- DObtaining a baseline oxygen saturation取得基線血氧飽和度
— Explanation · 中文詳解 —
心導管檢查涉及注射含碘顯影劑（Radiopaque contrast dye），若病人具有過敏史，可能引發嚴重的過敏反應（Anaphylaxis），甚至威脅生命。在進行侵入性檢查前，護理師必須進行風險評估以預防致命併發症。雖然禁食與基線評估重要，但過敏史直接關乎病人的生理性安全，屬於最優先的護理評估項目。
Cardiac catheterization involves the injection of iodine-based contrast dye, which poses a significant risk of severe anaphylaxis in clients with allergies to iodine or shellfish. While NPO status and baseline assessments are important, identifying allergy risks is the most critical safety priority to prevent life-threatening complications.
✦ 台美臨床差異
台美臨床在術前評估過敏史的重點一致。美國醫院會特別詢問對貝殼類（Shellfish）的過敏史，因其與碘過敏的關聯性在臨床評估中被高度重視。
