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 value when monitoring for this drug side effect?

Choice A rationaleWhile a complete blood count (CBC) is an essential lab value for monitoring many conditions and potential side effects, it is not the primary concern when administering high doses of azithromycin, especially with co-administration of acetaminophen. The focus should be on liver function.Choice B rationaleUrinalysis is useful in diagnosing and monitoring various conditions but is not directly relevant to monitoring the side effects of azithromycin and acetaminophen. These medications do not typically cause urinary abnormalities that would necessitate frequent urinalysis.Choice C rationaleElectrolytes are not directly affected by azithromycin and acetaminophen use. Although monitoring electrolytes can be essential in broader contexts, these specific medications do not primarily impact electrolyte balance requiring focused monitoring.Choice D rationaleLiver enzymes are the key lab values to monitor when administering high doses of azithromycin and acetaminophen. Both medications are metabolized by the liver and can cause hepatotoxicity. Monitoring liver enzymes helps in detecting early signs of liver damage and preventing further complications.
