The nurse is caring for a patient who has jaundice, dark urine, malaise, light-colored stools, nausea, and vomiting. What is this patient most likely experiencing?

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.

Choice A reason: Hydrochlorothiazide can treat diabetes insipidus by reducing urine output via sodium reabsorption, but this is a secondary use. Its primary role is in hypertension management, as it lowers blood pressure by decreasing blood volume, making this choice less accurate.

Choice B reason: Hydrochlorothiazide, a thiazide diuretic, is primarily used for hypertension by promoting sodium and water excretion, reducing blood volume and vascular resistance. It’s a first-line treatment per guidelines, effectively lowering blood pressure, making this the correct choice for its primary indication.

Choice C reason: Hydrochlorothiazide treats edema in heart failure or renal disease by increasing diuresis, but this is a secondary indication. Its primary use is hypertension, where it reduces blood pressure more consistently across patients, making this choice less accurate than hypertension.

Choice D reason: Hydrochlorothiazide doesn’t protect against postmenopausal osteoporosis. While thiazides reduce urinary calcium loss, they’re not indicated for osteoporosis prevention, unlike bisphosphonates. Their primary role is hypertension management, making this choice incorrect for the drug’s main therapeutic use.
