A 15-year-old client is rushed to the ER after taking an entire bottle of acetaminophen (Tylenol) in a suicide attempt. The nurse’s priority is obtaining which lab results?

Number 1 is correct.

An overdose of acetaminophen can lead to hepatotoxicity, causing acute liver injury, permanent liver damage, or death. The nurse’s priority would be obtaining lab tests used to determine liver function. Liver function can be determined by analyzing the liver enzymes aspartate transaminase and alanine transaminase.
