The nurse assesses a patient who takes ibuprofen [Advil] on a regular basis. Which finding would indicate a severe adverse effect of ibuprofen therapy?

Choice A reason: Jaundice indicates liver dysfunction, but ibuprofen rarely causes hepatotoxicity at standard doses. It’s more associated with gastrointestinal issues due to COX-1 inhibition, reducing protective prostaglandins in the stomach lining. While possible with overdose, jaundice is less common than gastrointestinal bleeding, making this choice less likely. Choice B reason: Ibuprofen, an NSAID, inhibits COX-1, reducing gastric mucosal protection, which can lead to ulcers or gastrointestinal bleeding. Bloody emesis (hematemesis) indicates severe gastrointestinal damage, a well-documented adverse effect requiring immediate intervention, making this the correct choice for a severe ibuprofen-related complication. Choice C reason: Itching may indicate a mild allergic reaction or skin irritation, not a severe adverse effect of ibuprofen. While possible, it’s less critical than gastrointestinal bleeding, which poses life-threatening risks due to ibuprofen’s impact on gastric mucosa, making this choice less severe and incorrect. Choice D reason: Dysmenorrhea (painful periods) is a condition ibuprofen treats, not an adverse effect. By inhibiting prostaglandins, ibuprofen reduces uterine contractions and pain. It doesn’t cause dysmenorrhea, making this choice irrelevant as an indicator of a severe adverse effect of ibuprofen therapy.
