護理師在協助病人取得知情同意時，應採取下列哪項行動？

核心概念：知情同意（Informed Consent）是病人自主權的體現，確保病人在充分了解資訊後，自願做出醫療決定。護理師在此過程中扮演重要角色，但其職責有明確界線。 為何正確答案對：選項 B 著重於確認病人的意願（自願性）及能力（心智健全，Competence），這是護理師在簽署前必須核實的關鍵環節。確保病人簽署的過程是自由且無壓力的，並且他有能力理解相關資訊，是護理師的法律與倫理責任。 為何其他選項錯：選項 D、A 雖然是知情同意過程中重要的資訊，但其主要解釋者應為執行醫療行為的醫師（Physician）。護理師的角色是協助醫師確保病人已獲得這些資訊，而非親自進行詳細的醫學解釋，以免超出其執業範圍或造成資訊混淆。選項 C 雖然護理師可以協助澄清，但這並非「首要」或「最核心」的行動，確認病人的意願與能力是更基礎且重要的步驟。 臨床思路（Priority / Safety）：在知情同意的過程中，病人自主權與醫療安全是最高原則。護理師的首要任務是確保病人能做出真正自主的決定，這建立在病人意願自由且具備決策能力之上。若病人意願受脅迫或能力受損，後續的資訊解釋與說明將失去意義。

Core concept: Informed consent embodies client autonomy and ensures that the client makes a medical decision voluntarily after being fully informed. The nurse plays an important role in this process but within clearly defined boundaries. Why the correct answer is correct: Option B focuses on confirming the client's willingness (voluntariness) and capacity (mental competence), which is the key step the nurse must verify before the document is signed. Ensuring that the signing process is free and uncoerced, and that the client has the capacity to understand the relevant information, is the nurse's legal and ethical responsibility. Why the other options are incorrect: Options D and A describe information that is important within the informed consent process, but the primary person responsible for explaining this information is the physician who performs the procedure. The nurse's role is to assist the physician in confirming that the client has received this information, not to provide detailed medical explanations independently, which could exceed the nurse's scope of practice or create confusion. Although the nurse may clarify terminology (option C), this is not the primary or most central action; verifying the client's willingness and capacity is a more fundamental and important step. Clinical reasoning (Priority / Safety): During the informed consent process, the client's autonomy and medical safety are the highest principles. The nurse's primary task is to ensure that the client can make a truly autonomous decision, which depends on freedom from coercion and the capacity to decide. If the client's willingness is coerced or capacity is impaired, any further explanation of information becomes meaningless.

在美國，護理師在知情同意過程中，雖然主要由醫師負責解釋複雜的醫療資訊、風險、益處及替代方案，但護理師有責任評估病人是否理解這些資訊，並確認病人簽署過程的自願性與能力。護理師也會在同意書上簽名作為見證人，證明已與病人討論過相關事項。台灣的臨床實務也類似，醫師負主要解釋責任，護理師輔助並確認。此題的重點在於護理師的核心職責，此部分在台美間並無顯著差異。
