對比劑（Contrast dye）通常含有碘（Iodine），對於對貝類或碘過敏的病人，可能引發嚴重的全身性過敏反應，甚至過敏性休克（Anaphylactic shock）。在進行任何顯影檢查前，護理師的首要任務是進行安全篩檢（Safety assessment），確保病人無過敏史，並評估腎功能以預防對比劑腎病變（Contrast-induced nephropathy）。
Contrast dye typically contains iodine and may trigger a severe systemic allergic reaction, even anaphylactic shock, in clients allergic to shellfish or iodine. Before any imaging study using contrast, the nurse's primary task is to perform a safety assessment to confirm the absence of allergies and to evaluate renal function in order to prevent contrast-induced nephropathy.
