A nurse is providing teaching to a client who has a new prescription for allopurinol to treat gout. Which of the following instructions should the nurse include in the teaching?

Choice A rationale Experiencing a rash while taking allopurinol is not harmless. It can be a sign of a serious allergic reaction, such as Stevens-Johnson syndrome or toxic epidermal necrolysis. Choice B rationale Increasing fluid intake is crucial when taking allopurinol. It helps to prevent kidney stones and ensures that uric acid is effectively excreted from the body. Choice C rationale Increasing dietary fiber intake is not specifically related to the use of allopurinol. While fiber is beneficial for overall health, it does not directly impact the effectiveness or safety of allopurinol. Choice D rationale Taking one dose every hour until the pain subsides is incorrect and dangerous. Allopurinol should be taken as prescribed by a healthcare provider, typically once or twice daily.
