A nurse is teaching a client about the management of pericarditis. Which off the following client statements indicates to the nurse an understanding of the teaching?

Rationale: A. While adequate hydration is generally beneficial, pericarditis management does not typically require aggressive fluid intake, and overhydration could exacerbate complications, especially if there is concurrent heart failure. B. This statement is not relevant to pericarditis, as having pericarditis does not necessitate avoidance of driving unless there are specific complications or comorbidities. C. NSAIDs are used to reduce inflammation and pain in pericarditis; sexual activity is not contraindicated while on these medications unless the client is experiencing symptoms that limit activity. D. This indicates understanding because chest pain can signify worsening pericarditis or complications such as cardiac tamponade or myocardial involvement, and prompt evaluation is necessary.
