腹主動脈瘤（AAA）的病人若出現突發且劇烈的下背痛或腹痛，這通常是動脈瘤即將破裂或已經破裂的徵兆（Rupture/Expansion）。這是危及生命的急症，需要立即通知外科醫師並準備緊急手術介入。其他選項如可見搏動是 AAA 的常見表徵，血壓 130 mmHg 屬於控制範圍內，高血壓病史是風險因子而非急性急症徵象。
Sudden onset of lower back pain in a client with an abdominal aortic aneurysm is a critical sign indicating potential aneurysm expansion or rupture. This requires immediate medical intervention to prevent hemorrhagic shock and death. While pulsations and hypertension are relevant findings, they do not constitute an acute emergency compared to signs of imminent rupture.
