病人已簽署「不施行復甦術（DNR）」，隨後發生心跳停止。護理師的優先行動為何？
A nurse is caring for a client who has a Do-Not-Resuscitate (DNR) order. The client goes into cardiac arrest. What is the priority action for the nurse?
- AAssess the client for a pulse and respirations✓ 正解評估病人是否有脈搏和呼吸
- BCall a code blue and begin chest compressions呼叫急救團隊並開始胸外按壓
- CProvide comfort care and support the family提供舒適護理並支持家屬
- DCheck the chart to ensure the DNR order is signed查閱病歷以確保不施行心肺復甦術（DNR）醫囑已簽署
即使有 DNR 醫囑，當發生疑似心跳停止時，護理師的首要行動仍是確認病人的生理狀態（評估呼吸與脈搏）。確認死亡後，護理師應尊重 DNR 意願不進行急救，並轉向提供舒適護理與家屬支持。B 選項違反 DNR；C 是後續行動；D 應在平時就確認好。
Even when a DNR order is in place, the nurse's first action upon a suspected cardiac arrest is to confirm the client's physiological status (assessing respiration and pulse). Once death is confirmed, the nurse should honor the DNR by withholding resuscitation and shift to providing comfort care and family support. Option B violates the DNR; option C is a subsequent action; option D should have been confirmed in advance.
美國 DNR 具法律約束力，誤救可能導致訴訟；台灣臨床實務上，有時家屬會於最後一刻反悔，護理師需面臨倫理兩難。
