病人安排進行核磁共振（MRI）檢查。護理師在檢查前應優先執行哪項評估？
A client is scheduled for an MRI. Which assessment is most critical for the nurse to perform before the procedure?
- ADetermine the client's allergy to iodine.確定病人是否對碘過敏
- BAssess for a history of claustrophobia.評估是否有幽閉恐懼症病史
- CCheck for any metallic implants or fragments.✓ 正解檢查是否有金屬植入物或碎片
- DAsk about the client's last meal intake.詢問病人最後一餐的攝取情況
— Explanation · 中文詳解 —
MRI 的強大磁場會吸引鐵磁性金屬物，導致體內植入物（如心律調節器、動脈瘤夾）移位或產熱灼傷組織，造成致命危險。因此，確認金屬物是物理安全的首要任務。A（幽閉恐懼）重要但非生命威脅；C（碘過敏）與 MRI 無關（MRI 多使用釓劑而非碘造影劑）；D（禁食）視檢查項目而定，非通用核心安全點。
The powerful magnetic field of an MRI can displace metallic implants or fragments, causing severe internal injury or tissue damage. Therefore, screening for metal objects is the critical safety priority before the procedure, whereas issues like claustrophobia or iodine allergies are secondary or unrelated to MRI safety.
✦ 台美臨床差異
美國放射學會對金屬篩檢有標準化查檢表；台灣臨床實務同樣嚴格，通常需由病人及家屬簽署核對表。
