王刚有便秘病史，来医院做全面的医学检查。明天上午他要进行肠镜检查。刘梅是他的责任护士，正在和王刚谈话，告诉他肠镜前肠道准备的方法和注意事项。
刘梅：早上好，王刚，明天上午医生将给你做肠镜检查，检查前需要清洁肠道，下面我将告诉你如何去做。
王刚：好的，我会认真听。
刘梅：为提高肠道清洁度，今天中饭和晚饭以低纤维半流质饮食为主，如粥、馒头、面条等。
王刚：好的。
刘梅：根据医生开具的医嘱，给你3袋口服肠道清洁剂，名称是聚乙二醇电解质散，它是容积性泻药，不会导致水和电解质紊乱，每袋用1 000 mL温开水冲服，3袋共溶入3 000 mL温水，今天晚上8点喝1 000 mL，明天早上5点喝2 000 mL。建议每10分钟喝250 mL，2小时内喝完。在这个过程中腹部有不适是正常的，如有严重腹胀或不适，可放慢服用速度或暂停服用，待症状消除后再继续服用，腹泻直至体内没有粪渣。听明白了吗？
王刚：我基本清楚了。
刘梅：如果你需要，我可以帮你溶药和观察排便的情况。
王刚：好的，非常感谢你，刘梅，我会记住你的嘱咐。
