護理師照顧一位敗血症（sepsis）病人，哪項措施對感染控制至關重要？

核心概念：敗血症（sepsis）是一種由感染引起的、危及生命的全身性發炎反應，會導致器官功能障礙。早期診斷和及時的治療是改善預後的關鍵。感染控制在敗血症的照護中至關重要，目標是快速清除感染源並支持器官功能。 為何正確答案 C 對：敗血症的黃金治療時間非常短暫。研究顯示，在症狀出現或懷疑敗血症後一小時內給予廣效性抗生素（broad-spectrum antibiotics），能顯著降低死亡率和併發症。此為臨床實踐準則（guideline）中的核心要求。 為何其他選項錯： A. 快速靜脈輸液（IV fluids）是敗血症治療的一部分，用於維持血壓和灌流，但它本身並非控制感染的直接措施，且必須在評估血行動力學穩定性的基礎上進行，過快給予可能導致體液過量（fluid overload）。 B. 雖然在給予抗生素前取得血液培養（blood cultures）是標準步驟，以鑑定病原體，但若因此延誤給予抗生素超過一小時，反而會損害病人預後。因此，在有指徵的情況下，應在給予抗生素的同時或立即進行採樣，而不是等待培養結果。 D. 密切監測尿量（urine output）是評估器官灌流（organ perfusion）的重要指標，對於敗血症病人很重要，但它屬於監測範疇，而非最關鍵的感染控制行動（critical intervention for infection control）。 臨床思路（Priority / Safety）：此題的優先級（priority）在於「感染控制」與「治療時效性」。敗血症是急症，時間就是生命。快速有效抑制病原體是首要目標，抗生素的及時給予直接影響存活率。

Core concept: Sepsis is a life-threatening systemic inflammatory response caused by infection that leads to organ dysfunction. Early diagnosis and timely treatment are key to improving prognosis. Infection control is paramount in sepsis care, with the goal of rapidly eliminating the source of infection and supporting organ function. Why correct answer C is right: The golden window for sepsis treatment is very brief. Research shows that administering broad-spectrum antibiotics within one hour of symptom onset or suspected sepsis significantly reduces mortality and complications. This is a core requirement in clinical practice guidelines. Why other options are wrong: A. Rapid IV fluid resuscitation is part of sepsis treatment, used to maintain blood pressure and perfusion, but it is not itself a direct measure for infection control, and must be guided by hemodynamic stability—rapid administration may cause fluid overload. B. Although obtaining blood cultures before administering antibiotics is the standard step to identify pathogens, delaying antibiotic administration beyond one hour will worsen prognosis. Therefore, when indicated, sampling should be done simultaneously with or immediately before antibiotic administration, not after waiting for culture results. D. Closely monitoring urine output is an important indicator of organ perfusion and important for sepsis patients, but it falls under monitoring rather than the most critical intervention for infection control. Clinical reasoning (Priority / Safety): The priority of this question lies in 'infection control' and 'time sensitivity.' Sepsis is an emergency—time is life. Rapid and effective suppression of pathogens is the primary goal, and timely administration of antibiotics directly affects survival.

敗血症的早期識別與「一小時內給予廣效性抗生素」的觀念，在美國的醫療體系中已是高度標準化的臨床指引（ Surviving Sepsis Campaign guidelines）。台灣的醫療機構也普遍遵循此原則，但實際執行上的協調與效率可能因醫院層級、科別及資源而異。例如，急診、加護病房的執行力通常較高。
