A nurse is caring for a client who reports chest pain. Which of the following laboratory findings indicates myocardial damage?
Correct answer
A
Rationale
The correct answer is A: Troponin 11.8 ng/mL. Troponin is a specific marker released by damaged heart muscle cells during a heart attack. Elevated troponin levels indicate myocardial damage. ESR (B) and B-type natriuretic peptide (C) are not specific for myocardial damage. aPTT (D) is a test for blood clotting function and not indicative of myocardial damage.
