The nurse is caring for a patient who is receiving a high dose of intravenous azithromycin to treat an infection. The patient is also taking acetaminophen for pain. The nurse should expect to review which lab values when monitoring for this drug side effects?

a) Complete blood counts (CBC) are useful for monitoring infection, anemia, or bone marrow suppression, but they are not the primary concern for azithromycin and acetaminophen toxicity. b) Electrolytes are important for general health but are not directly related to the major side effects of these drugs. c) Liver enzymes (AST, ALT) should be monitored because both azithromycin and acetaminophen can cause hepatotoxicity, especially at high doses. Acetaminophen overdose is a known cause of liver failure. d) Urinalysis may be helpful in assessing kidney function, but it is not the primary focus when monitoring for drug-induced liver toxicity.
