A client with cirrhosis has the following laboratory results: albumin 4.9 g/dl. (3.5-5 g/dL), PT 13 seconds (11-12.5 sec), and serum ammonia 68 mcg/dL (15-45 mcg/dL). Based on this information, what is the nurse's next action?

Elevated serum ammonia levels can lead to hepatic encephalopathy, which affects mental status and consciousness, making this the priority assessment. The PT is slightly prolonged but not alarmingly high; bleeding is less of a concern compared to the elevated ammonia. This action is important in assessing fluid accumulation but is not as critical as assessing mental status in this scenario. While part of a comprehensive abdominal assessment, this is not the most critical action given the elevated ammonia level.
