— Explanation · 中文詳解 —
東莨菪鹼（Scopolamine）是一種抗膽鹼激導性藥物，主要用於預防暈車或手術後噁心嘔吐。其藥理特性包括抑制副交感神經，若藥物殘留在手指上並接觸眼睛，會引起瞳孔散大（mydriasis）及睫狀肌麻痺，導致視力模糊與畏光，對病人造成不必要的困擾與風險。因此，應用藥後徹底清潔雙手是預防藥物誤入眼睛的關鍵安全指導。
The priority instruction for a client using a scopolamine patch is to wash hands thoroughly after application to prevent accidental transfer of the medication to the eyes. Contact with the eyes can cause mydriasis and blurred vision due to the drug's anticholinergic effects, making hand hygiene a critical safety measure.
