A nurse is educating a client about a new prescription for mesalamine for Crohn's disease. Which of the following statements by the client indicates an understanding of the teaching?

A. "I will wear sunscreen with the use of this medication.": Mesalamine is an aminosalicylate with anti-inflammatory effects on the intestinal mucosa and can increase photosensitivity in some clients. Enhanced sensitivity to ultraviolet light may predispose the client to sunburn. Using sunscreen and protective clothing helps reduce the risk of skin injury while on therapy. B. "I will reduce my fluid intake with this medication.": Adequate hydration is important while taking mesalamine because the medication is excreted renally and can, in rare cases, contribute to nephrotoxicity. Decreasing fluid intake may increase the risk of renal complications and concentrated urine. Clients are generally encouraged to maintain appropriate hydration. C. "I will take this medication with ibuprofen for better pain control.": Nonsteroidal anti-inflammatory drugs such as ibuprofen can irritate the gastrointestinal mucosa and may exacerbate inflammatory bowel disease symptoms. Concurrent use may increase the risk of GI bleeding or worsening inflammation. D. "I should crush this medication so I can take it easily.": Many mesalamine formulations are enteric-coated or delayed-release to ensure delivery of the drug to specific areas of the intestine. Crushing the tablet disrupts this protective coating and alters drug release, reducing therapeutic effectiveness and increasing gastric irritation.
