NAPLEX Question of the Day
Test your knowledge with a hand-picked multiple-choice question.
A 29-year-old breastfeeding woman presents 24 hours after a vaginal delivery requesting pain control for perineal laceration. She has normal renal and hepatic function and no history of substance use disorder. The obstetrician prescribed acetaminophen plus codeine as needed. Pharmacogenetic testing performed during pregnancy shows CYP2D6 ultrarapid metabolizer status with multiple gene duplications; her newborn is healthy. She plans to breastfeed exclusively and is concerned about medication safety for the infant. Vital signs are stable, and her pain score is 7 out of 10. The team asks for guidance on analgesic selection.
