護理師照顧一位嗜中性白血球減少的病人，哪項評估結果最為重要？

核心概念：嗜中性白血球減少症（Neutropenia）的護理監測重點。 為何正確答案對： C. 發燒（Temperature of 101°F / 38.3°C）是嗜中性白血球低下病人最重要且最危險的評估結果。由於病人缺乏足夠的嗜中性白血球來產生有效的發炎反應，因此即使是嚴重的細菌感染，也可能沒有明顯的發燒或其他發炎徵象。體溫升高往往是敗血症（Sepsis）的唯一或最主要的警訊，必須立即處理，否則可能迅速惡化為休克甚至死亡。 為何其他選項錯： B. 白血球計數 3,000/mm³ 雖然偏低（正常值約 4,000-11,000/mm³），但這是病人既有的狀況，發燒才是急性、危急的變化。 C. 疲勞（Reports of fatigue）是許多慢性疾病或治療的副作用，雖然也可能是感染的徵兆，但不如發燒來得直接與緊急。 D. 口乾（Dry mouth）可能與藥物副作用、脫水或口腔衛生不良有關，但不是 Neutropenia 病人感染的關鍵警訊。

Core concept: Nursing monitoring priorities in neutropenia. Why the correct answer is correct: A. Fever (temperature of 101°F / 38.3°C) is the most important and dangerous assessment finding in a neutropenic patient. Because the patient lacks sufficient neutrophils to mount an effective inflammatory response, even severe bacterial infections may not produce obvious fever or other inflammatory signs. Elevated temperature is often the only or major warning sign of sepsis and must be addressed immediately; otherwise the condition may rapidly progress to shock or death. Why the other options are wrong: B. A WBC of 3,000/mm³ is below normal (about 4,000-11,000/mm³), but this is the patient's pre-existing condition; fever represents an acute, critical change. C. Reports of fatigue are a side effect of many chronic illnesses or treatments and may suggest infection, but are less direct or urgent than fever. D. Dry mouth may relate to medication side effects, dehydration, or poor oral hygiene, but is not a key infection warning in a neutropenic patient.
