Practice Question
The nurse reviews the laboratory results of a client diagnosed with viral hepatitis. Which increased laboratory result is most important for the nurse to report to the health care provider?
Answer Choices:
Correct Answer:
Alanine aminotransferase (ALT) of 2,600 U/L (43.42 mckat/L).
Rationale:
🌼 ALT is the most liver-specific enzyme for hepatocellular damage.
🌼 ALT 2,600 U/L indicates massive hepatocyte injury.
🌼 Viral hepatitis typically elevates ALT more than AST.
🌼 Extremely high levels signal risk for acute liver failure.
🌼 Must be reported immediately for urgent intervention.
AST 2,200 U/L
🌼 Elevated but less liver-specific than ALT.
🌼 Still concerning, but ALT is more critical.
Platelets 460,000
🌼 Elevated platelets do not indicate liver failure.
🌼 Not the priority.
Ammonia 55
🌼 Mildly elevated; concerning but not the highest urgency.
🌼 ALT signals more severe liver injury.
