A client receives a prescription for itraconazole. Which statement made by the client requires additional instruction by the nurse?

Choice A reason: Monitoring for changes in stool color can be important when taking certain medications, but it is not specifically required for itraconazole. Choice B reason: Drinking grapefruit juice actually increases the effects of itraconazole by inhibiting its metabolism, not reducing its effects. Therefore, patients should avoid grapefruit juice while taking itraconazole. Choice C reason: Antacids can decrease the absorption of itraconazole, making it less effective. Patients should take itraconazole with food and an acidic drink, like cola or orange juice, but not with antacids. Choice D reason: Reporting any difficulty with breathing is appropriate advice for any medication and does not require additional instruction.
