護理師正在評估一位有腹水（ascites）的肝硬化病人，下列何項評估發現表示病情惡化？
A nurse is assessing a client with cirrhosis who has ascites. Which assessment finding indicates a worsening condition?
- ADecreased abdominal girth measurement腹圍測量值減少
- BDevelopment of asterixis (flapping tremor)✓ 正解出現撲翼樣震顛
- CDaily weight gain of 1 lb每日體重增加 1 磅
- DUrine output of 500 mL in 8 hours8 小時內尿液排出量為 500 mL
肝硬化病人因肝功能受損，無法有效代謝體內蛋白質分解產生的氨（Ammonia）。撲翼樣震顫（Asterixis）是肝性腦病變（Hepatic Encephalopathy）的早期神經學徵象，表示氨中毒已影響中樞神經系統。這意味著肝臟功能已嚴重衰竭，若不立即處理，可能迅速惡化為昏迷，因此相對於體重增加等慢性變化，此發現最危急。
Patients with cirrhosis have impaired liver function and cannot effectively metabolize ammonia produced from protein breakdown. Asterixis (flapping tremor) is an early neurologic sign of hepatic encephalopathy, indicating that ammonia toxicity has affected the central nervous system. This means hepatic function has severely failed and, without immediate intervention, the patient may rapidly progress to coma; relative to chronic changes such as weight gain, this finding is the most emergent.
