一名 25 歲患有廣泛性焦慮症的個案，表現出語速快、不安及強烈的不祥預感。護理師的首要介入措施為何？
A 25-year-old client with generalized anxiety disorder presents with rapid speech, restlessness, and a feeling of impending doom. Which intervention is the highest priority for the nurse?
- AMaintain a calm, quiet, and low-stimulus environment✓ 正解維持安靜、低刺激的環境
- BTeach the client deep breathing exercises to use immediately教導病人立即使用深呼吸練習
- CAdminister an as-needed dose of an antianxiety medication給予處方抗焦慮藥物（按需劑量）
- DEncourage the client to talk about the source of their anxiety鼓勵病人談論焦慮的來源
面對廣泛性焦慮症（Generalized Anxiety Disorder, GAD）急性發作的個案，首要原則是降低環境刺激（Low-stimulus environment）。焦慮會導致個案感官過敏、注意力渙散，過多的外部刺激會加劇其不適感與不安。在個案情緒尚未穩定前，深層心理諮商或複雜的教學計畫皆無法發揮功效。護理師應先營造安全、安靜的環境，待個案情緒平穩後，再進行進一步的評估與衛教，此為心理健康護理中「先穩定環境再處理心理問題」的優先順序。
For a client in an acute episode of generalized anxiety disorder (GAD), the first principle is to reduce environmental stimulation (a low-stimulus environment). Anxiety makes the client hypersensitive to sensory input and unable to focus, and excessive external stimuli intensify discomfort and unease. Before the client's emotional state has stabilized, in-depth psychological counseling or complex teaching plans cannot be effective. The nurse should first create a safe, quiet environment, and only after the client has calmed down should further assessment and education be carried out. This reflects the mental-health nursing priority of stabilizing the environment before addressing psychological issues.
