A nurse is caring for a client who has advanced liver disease. Which of the following laboratory results should the nurse monitor when assessing this client?

A. Serum troponin: Troponin is a marker of cardiac muscle injury and is not directly affected by liver function. Monitoring troponin is not routinely indicated in clients with liver disease unless cardiac issues are suspected. B. Glucose level: Glucose can be affected in liver disease due to impaired glycogen storage and gluconeogenesis, but it is not the most specific marker for assessing liver function or complications in advanced disease. C. Phosphate level: Phosphate levels are not typically a primary concern in liver disease. While electrolyte imbalances can occur, phosphate is not a key laboratory indicator for hepatic dysfunction. D. Serum ammonia: Serum ammonia levels are important to monitor in advanced liver disease because impaired hepatic metabolism can lead to hyperammonemia. Elevated ammonia levels increase the risk of hepatic encephalopathy and guide interventions to reduce neurotoxic effects.
