一位患有肝硬化的病患因食道靜脈曲張入院。護理師應對下列哪項醫囑提出疑問？

食道靜脈曲張（Esophageal varices）是肝門脈高壓的危險併發症，血管壁極薄且極易破裂導致大出血。護理核心在於「保護血管不被物理性損傷」。插入鼻胃管（NG tube）是一項具有高度機械性摩擦風險的操作，極可能刮破脆弱的曲張靜脈導致不可控的出血，因此在急性期或未確認安全性前應極力避免（除非是專門用於止血的 Blakemore tube 且由資深醫師操作）。選項 A 的軟質飲食雖然也需小心，但風險低於硬質 NG 管；Propranolol（Beta 阻斷劑）常用於降低門脈壓力以預防出血，是標準治療。NPO（禁食）在急性期是為了手術或止血準備，屬於合理醫囑。此題考驗護理師對安全性（Safety）的敏感度。

Esophageal varices are a dangerous complication of portal hypertension; the vessel walls are extremely thin and prone to rupture, leading to massive hemorrhage. The core of nursing care is to 'protect the vessels from physical injury.' Insertion of a nasogastric (NG) tube carries a high risk of mechanical friction and can easily abrade the fragile varices, causing uncontrollable bleeding; therefore, it should be strictly avoided during the acute phase or when safety has not been confirmed (unless a Blakemore tube is specifically used for hemostasis under the supervision of an experienced physician). Option A (soft diet) requires caution as well, but its risk is lower than that of a rigid NG tube. Propranolol (a beta-blocker) is commonly used to reduce portal pressure and prevent bleeding and is part of the standard treatment. NPO (nothing by mouth) status during the acute phase is appropriate in preparation for surgery or hemostasis. This question tests the nurse's sensitivity to safety.

在美國，護理師對於禁忌症的主動挑戰（Questioning orders）被視為批判性思考的展現；台灣臨床文化中，護理師通常會先私下與醫師確認，較少在考卷上使用「Question the order」這種強烈的字眼，但核心安全原則一致。
