大腸鏡檢查前的腸道準備至關重要，清流質飲食能確保腸道乾淨，利於醫師觀察黏膜。A 不夠精確，須配合瀉劑使用；B 錯誤，抗凝血劑通常需在醫師指導下暫停以降低出血風險；D 錯誤，高纖維會殘留在腸道，嚴重干擾視野。
Bowel preparation before a colonoscopy is critical, and a clear liquid diet ensures the bowel is clean for adequate mucosal visualization. C is not precise enough and must be used with a laxative; B is incorrect because anticoagulants should usually be held under the physician's guidance to reduce bleeding risk; D is incorrect because high-fiber foods leave residue in the bowel and seriously obscure the view.
