A nurse is reinforcing teaching with a client who is taking ibuprofen to treat chronic hip pain. Which of the following instructions should the nurse include in the teaching?

A. Weight gain is not a typical adverse effect of ibuprofen; the client should be monitored for other side effects instead. B. Regular eye exams are not required for ibuprofen therapy; this is more relevant for medications like hydroxychloroquine or corticosteroids. C. Antacids can interfere with the absorption of ibuprofen, so it is recommended to take ibuprofen at least 2 hours before or after antacids to ensure proper effectiveness. D. Alcohol can increase the risk of gastrointestinal bleeding with ibuprofen, so clients should be advised to avoid or limit alcohol entirely rather than consume it regularly, even in small amounts.
