護理師正在評估一位聲稱感到非常焦慮和恐懼的病人。病人來回踱步且顯得過度警覺，最恰當的護理診斷是什麼？
A nurse is assessing a client who reports feeling very anxious and fearful. The client is pacing and seems hypervigilant. Which nursing diagnosis is most appropriate?
- AIneffective Health Maintenance無效的健康維護
- BAnxiety✓ 正解焦慮
- CSocial Isolation社交孤立
- DDisturbed Body Image身體意象紊亂
本題的核心在於辨識病人的臨床表現並對應至正確的護理診斷。焦慮（Anxiety）是一種主觀的痛苦感受，常伴隨生理及行為上的改變。題目中病人報告「感到焦慮和恐懼」，且觀察到「來回踱步（pacing）」及「過度警覺（hypervigilant）」，這些皆為焦慮症狀的典型表現。護理師需區分焦慮與其他心理健康診斷，焦慮症狀通常與當下的不安感直接相關，而非長期自我形象缺失或社交隔離。
The core of this question is to identify the client's clinical presentation and match it to the correct nursing diagnosis. Anxiety is a subjective experience of distress often accompanied by physiological and behavioral changes. The client reports 'feeling anxious and fearful' and is observed 'pacing' and 'hypervigilant,' which are typical manifestations of anxiety. The nurse must distinguish anxiety from other mental health diagnoses; anxiety symptoms are usually directly related to immediate unease, not long-term self-image deficits or social isolation.
