A client is seen in the emergency department with a heart failure exacerbation due to noncompliance with medications and fluid restrictions. Which key diagnostic result should the nurse assess to determine the severity of the client's heart failure exacerbation?
Blood urea nitrogen (BUN)
Troponin
B-type natriuretic peptide (BNP)
Electrocardiogram
The Correct Answer is C
A. Elevated BUN can indicate kidney dysfunction but is not specific for assessing heart failure severity.
B. Elevated troponin levels indicate myocardial injury or infarction, not heart failure exacerbation.
C. B-type natriuretic peptide (BNP) levels are directly correlated with the severity of heart failure, as they are released in response to ventricular volume expansion and pressure overload.
D. An electrocardiogram (ECG) can show arrhythmias or ischemia but does not directly measure heart failure severity.
