A nurse is reviewing laboratory results for a client who has pericarditis. Which of the following blood test results should the nurse anticipate? (Select All that Apply.)

Rationale: A. ESR is a nonspecific marker of inflammation. In pericarditis, inflammation of the pericardium leads to an elevated ESR, reflecting the systemic inflammatory response. B. BNP is elevated in heart failure due to ventricular stretch and volume overload. While pericarditis can affect cardiac function, BNP is not a primary diagnostic marker for pericarditis unless there is associated heart failure. C. CRP is another nonspecific marker of inflammation. It is commonly elevated in pericarditis and correlates with disease activity and severity. D. Blood urea nitrogen is a marker of renal function and is not typically affected by pericarditis unless there is concurrent kidney impairment. E. TSH is used to assess thyroid function and is not related to the inflammatory process seen in pericarditis.
