護理師正在為明天上午進行擇期大腸鏡檢查的病人做準備。護理師應包含哪些指導內容？（選所有適合的）
A nurse is preparing a client for an elective colonoscopy scheduled for tomorrow morning. Which instructions should the nurse include? (Select all that apply.)
- AMaintain a clear liquid diet the day before the procedure✓ 正解在檢查前一天維持清流質飲食
- BDrink the prescribed polyethylene glycol solution as directed✓ 正解依照指示飲用處方之聚乙二醇溶液
- CAvoid consuming red or purple-colored liquids✓ 正解避免攝取紅色或紫色液體
- DStop taking all antihypertensive medications 48 hours prior在檢查前 48 小時停止服用所有降血壓藥物
- EInform the provider if you take any anticoagulant medications✓ 正解若服用任何抗凝血藥物，應告知醫師
大腸鏡檢查的成功關鍵在於腸道清潔度。清流質飲食（A）和瀉藥（B）能確保糞便排出，不影響內視鏡視野。紅色或紫色液體（C）會殘留在腸道內，被誤認為出血，因此必須避免。抗凝血劑（E）會增加切除息肉時的出血風險，必須提前告知醫療團隊。至於血壓藥（D），除非醫師特別指示，否則通常應繼續服用以維持生命徵象穩定，不可擅自停藥。這類題目考驗護理師對常見檢查前風險管理與病人教育的掌握程度。
The success of colonoscopy depends on bowel cleanliness. A clear liquid diet (A) and laxatives (B) ensure evacuation of stool and do not obscure the endoscopic view. Red or purple liquids (C) leave residue in the bowel and may be mistaken for blood, so they must be avoided. Anticoagulants (E) increase the risk of bleeding when polyps are resected and must be reported to the medical team in advance. As for antihypertensive medications (D), unless specifically instructed by the physician, they should usually be continued to maintain stable vital signs and should not be discontinued without authorization. This type of question tests the nurse's grasp of pre-procedure risk management and patient education for common examinations.
美國的腸道準備衛教通常由專科護理師或診所個管師提供詳細的手冊；台灣多由內視鏡室護理師或門診護理師在報到時提供統一印製的說明單張，重點在於清腸藥物的服用時間點。
