護理師正在進行護理優先順序排序。下列哪位病人應優先評估？
A nurse is prioritizing care for a group of clients. Which client should the nurse assess first?
- AA client with a new onset of sudden confusion✓ 正解新發急性意識混亂的病人
- BA client with a scheduled dressing change for a surgical site手術部位需定期換藥的病人
- CA client reporting pain at a rate of 5 on a scale of 0-10主訴疼痛程度為 0-10 分中的 5 分的病人
- DA client who just returned from surgery and is complaining of nausea剛返回病房並抱怨噁心的術後病人
護理優先順序排序的核心在於應用 ABC（Airway, Breathing, Circulation）原則與評估病人的生命威脅程度。突發性意識改變（Sudden onset of confusion）常暗示急性腦部灌流不足、低血糖、缺氧或代謝性腦病變，這些狀況可能迅速惡化導致不可逆的腦損傷，屬於立即性的生命威脅（Safety/Neurological priority）。相比之下，傷口換藥、疼痛管理或術後噁心雖需照護，但通常不會在數分鐘內造成病人死亡或永久性傷害，故應將意識改變的病人列為首要評估。
The cornerstone of priority setting in nursing is the application of the ABC (Airway, Breathing, Circulation) framework and assessment of life-threat severity. Sudden onset of confusion often signals acute cerebral hypoperfusion, hypoglycemia, hypoxia, or metabolic encephalopathy; these conditions may worsen rapidly and cause irreversible brain injury and therefore represent an immediate life threat (a safety/neurological priority). By contrast, dressing changes, pain management, and postoperative nausea require nursing care, but do not generally cause death or permanent harm within minutes; the client with altered mental status must therefore be assessed first.
