病人預計進行檢查，護理師在知情同意書的主要角色為何？
A client is scheduled for a diagnostic procedure. Which of the following is the nurse's primary role in informed consent?
- AProviding alternative treatment options提供替代治療選項
- BWitnessing the client's signature on the consent form✓ 正解見證病人在同意書上的簽名
- CEnsuring the client understands the procedure確保病人了解該程序
- DExplaining the risks and benefits of the procedure解釋該程序的風險和益處
知情同意（Informed Consent）的法律核心在於確保病人是在充分了解程序、風險、效益及替代方案後，由醫師親自說明並取得同意。護理師在此過程中的法律責任是作為「見證人（Witness）」，確認病人簽署同意書時意識清醒、無受脅迫，且簽名過程符合規範。護理師的角色不涉及解釋醫療內容，以免超越專業執業範圍（Scope of Practice）。
The nurse’s primary legal responsibility regarding informed consent is to witness the client’s signature, confirming that the client is competent, signing voluntarily, and appears to understand the procedure. The healthcare provider is responsible for explaining the risks, benefits, and alternatives. Nurses must avoid providing medical explanations to prevent practicing beyond their scope.
在美國臨床實務中，醫師必須親自向病人解釋醫療程序。護理師若發現病人對程序內容有疑問，必須通知醫師回來進行解釋，護理師絕對不能代為說明，以免承擔法律風險。這與台灣臨床有時護理師會協助補充說明的情況不同。
