734. Answer: 4

Rationale: In adults, overdose of acetaminophen causes liver damage. The correct
option is an indicator of liver function and is the only option that indicates an
abnormal laboratory value. The normal direct bilirubin level is 0.1 to 0.3 mg/dL (1.7
to 5.1 mcmol/L). The normal sodium level is 135 to 145 mEq/L (135 to 145 mmol/L).
The normal prothrombin time is 11 to 12.5 seconds (11 to 12.5 seconds). The normal

platelet count is 150,000 to 400,000 mm (150 to 400 × 10 /L).
Test-Taking Strategy: Focus on the subject, acetaminophen toxicity. Knowledge
that acetaminophen causes liver damage and knowledge of normal laboratory
results will assist you in answering this question. The correct option is the only
abnormal value. Also, of all the options, the bilirubin level is the laboratory value
most directly related to liver function.
