A male client who has been taking a high dose of a nonsteroidal antiinflammatory drug (NSAID) comes to the clinic reporting gastric pain and blood in his stool. The healthcare provider discontinues the NSAIDs and prescribes esomeprazole. Which information should the nurse include in this client's teaching plan?

A. NSAIDs should not be resumed without medical advice, especially if there has been significant gastrointestinal bleeding. B. A diet of milk, cream, and bland foods is not specifically recommended for this condition and does not address the underlying issue of NSAID-induced gastrointestinal damage. C. Black stools can indicate gastrointestinal bleeding, which is a serious side effect of NSAIDs and requires immediate medical attention. D. While esomeprazole can cause side effects like diarrhea or headache, they are not as urgent as reporting possible gastrointestinal bleeding.
