護理師協助術後行動受限的病人第一次坐床緣，病人坐起後表示頭暈。下列何者為優先護理措施？
A nurse is assisting a client with limited mobility to sit at the edge of the bed for the first time after surgery. The client reports dizziness upon sitting up. What is the priority nursing action?
- AEncourage the client to take deep breaths鼓勵客戶深呼吸
- BAssist the client to return to a supine position immediately✓ 正解立即協助客戶回到仰臥位
- CCall the physician to report the finding打電話通知醫師報告此發現
- DTake the client's blood pressure while sitting在坐著時測量客戶的血壓
此題核心為評估術後病人的安全與循環穩定性。病人出現頭暈（dizziness）是典型的姿勢性低血壓（orthostatic hypotension）徵兆，代表腦部血液灌流不足。在 NCLEX 的安全優先級原則（Safety Priority）中，當病人出現不穩定的生理症狀時，首要任務是恢復生理穩定，避免跌倒（fall precaution）。立刻讓病人躺下可減少重力對血液循環的影響，增加回心血量，進而緩解腦部缺血。
The core of this question is the assessment of postoperative patient safety and circulatory stability. The patient's dizziness is a typical sign of orthostatic hypotension, indicating inadequate cerebral perfusion. According to the NCLEX safety priority principle, when a patient develops unstable physiological symptoms, the primary task is to restore physiological stability and prevent falls (fall precaution). Having the patient lie down immediately reduces the effects of gravity on circulation, increases venous return, and thereby relieves cerebral ischemia.
