A client has been admitted with acute liver failure. Which assessment findings are most important concerning?

Rationale: A. Jaundice is caused by the accumulation of bilirubin in the blood due to impaired liver function. While it is an important clinical sign of liver dysfunction, jaundice develops gradually and is not an immediate life-threatening complication. It serves more as an indicator of underlying liver disease rather than an urgent signal requiring immediate intervention. B. Laboratory evidence of elevated bilirubin confirms liver dysfunction but does not provide real-time information about the client’s neurological or hemodynamic status. Lab values are important for diagnosis and monitoring but are less urgent than clinical manifestations of complications such as hepatic encephalopathy. C. Asterixis, also known as “flapping tremor,” combined with lethargy, is a hallmark sign of hepatic encephalopathy, a serious and potentially life-threatening complication of acute liver failure. These symptoms indicate that neurotoxins, especially ammonia, are accumulating in the brain due to the liver’s inability to metabolize them. Hepatic encephalopathy can rapidly progress from mild confusion to stupor or coma. Early recognition allows timely interventions, such as administering lactulose to reduce ammonia levels, monitoring neurological status, and preparing for possible intensive care support. These findings take priority over laboratory or physical exam findings that are not immediately dangerous. D. Mild hepatomegaly is common in acute liver failure and may indicate inflammation or congestion. While it is relevant for assessment, it is not an urgent concern compared with neurological changes like asterixis and lethargy.
