一位 45 歲廣泛性焦慮症病患至診所求診，主訴心悸並表示害怕失去控制。在急性期，護理師的首要護理措施為何？
A 45-year-old client with a history of generalized anxiety disorder presents to the clinic reporting palpitations and a fear of losing control. Which nursing intervention is the highest priority during this acute phase?
- AExplore the underlying causes of the anxiety探討焦慮的根本原因
- BTeach the client deep breathing exercises教導個案深呼吸練習
- CAdminister PRN anxiolytic medication給予處方用藥（PRN）抗焦慮藥物
- DMaintain a calm, quiet, and safe environment✓ 正解維持平靜、安靜且安全的環境
面對急性焦慮發作（Acute anxiety），護理師的首要任務是提供一個安全、平靜且低刺激的環境（Safe and calm environment）。病人的焦慮可能源於失控感，透過控制環境能減少感官過載，讓病人感到被支持與保護。在病人情緒穩定前，不適合進行深度的心理探討或教學，因為此時病人的認知功能可能受限。
When confronted with acute anxiety, the nurse's first priority is to provide a safe, calm, low-stimulation environment. The patient's anxiety may stem from a sense of loss of control, and managing the environment reduces sensory overload and helps the patient feel supported and protected. Before emotional stability is achieved, in-depth psychological exploration or teaching is not appropriate, because cognitive function may be impaired during acute anxiety.
