病人出現低血糖症狀。護理師預期其血糖值應低於多少？

這道題目旨在評估護理師對低血糖症狀及相關血糖值的認知。低血糖症（Hypoglycemia）是指血糖水平過低，無法為身體提供足夠能量的狀態。對於非糖尿病患者，血糖值通常在 70 mg/dL 以下即被視為低血糖；對於糖尿病患者，即使血糖高於 70 mg/dL，若從非常高的水平快速下降，也可能出現低血糖症狀。護理師需能識別這些症狀，並了解對應的血糖閾值，以快速介入處理，避免危及生命的神經功能障礙。 正確答案 C (60 mg/dL) 落在低血糖的定義範圍內，與病人出現低血糖症狀的描述相符。護理師應預期此血糖值。在臨床實務中，低血糖是一種醫療急症，需要立即給予快速作用的碳水化合物來提升血糖，以避免腦部損傷等嚴重併發症。 臨床思路：識別低血糖症狀（如顫抖、心悸、出汗、視力模糊、意識改變等）並立即測量血糖是護理師的首要任務。若血糖值確認偏低，應遵循「15-15法則」（Rule of 15）進行處理，即給予 15 克快速作用的碳水化合物，等待 15 分鐘後再測量血糖，若仍低於 70 mg/dL 則重複此步驟，直到血糖恢復正常。

This question evaluates the nurse's knowledge of hypoglycemia symptoms and the associated blood glucose values. Hypoglycemia is a state in which blood glucose is too low to provide adequate energy. For non-diabetic individuals, a glucose level below 70 mg/dL is generally considered hypoglycemic; in diabetic patients, even with a glucose level above 70 mg/dL, symptoms may occur if the glucose drops rapidly from a very high level. Nurses must recognize the symptoms and understand the corresponding glucose thresholds in order to intervene quickly and prevent life-threatening neurological dysfunction. The correct answer C (60 mg/dL) falls within the hypoglycemic range and is consistent with the client's presentation of hypoglycemic symptoms. Hypoglycemia is a medical emergency requiring immediate administration of fast-acting carbohydrates to raise blood glucose and prevent serious complications such as brain injury. Clinical reasoning: Recognizing hypoglycemic symptoms (such as tremor, palpitations, sweating, blurred vision, altered mental status) and immediately checking blood glucose is a top priority for the nurse. If hypoglycemia is confirmed, follow the 'Rule of 15' — give 15 grams of fast-acting carbohydrates, recheck the glucose after 15 minutes, and repeat if still below 70 mg/dL, until glucose returns to normal.
