Physiological Integrity QID 350

A nurse receives laboratory results for a patient suspected of having an acute myocardial infarction (AMI). Which laboratory result would the nurse report as confirmatory for AMI?

Decreased serum electrolytes

Elevated white blood cell count (WBC)

Elevated troponin I levels

Elevated B-type natriuretic peptide (BNP)

Explanation

Elevated troponin I levels are highly specific to cardiac muscle injury and are considered confirmatory for AMI. Elevated BNP suggests heart failure. Decreased serum electrolytes and elevated WBC may be related to other conditions and are nonspecific to AMI.
