Congestive Cardiac Failure

Congestive Cardiac Failure ( 35 Questions)

A nurse is caring for a client with suspected congestive heart failure. Which blood test is specifically used to measure heart strain and assist in the diagnosis of CHF?


Correct Answer: C

A) This choice is incorrect because a complete blood count (CBC) is a general blood test that measures different components of the blood, such as red blood cells, white blood cells, and platelets. It is not specifically used to measure heart strain or diagnose CHF.

B) This choice is incorrect because a basic metabolic panel (BMP) is a blood test that measures electrolytes, kidney function, and glucose levels. It is not specific to diagnosing CHF.

C) This choice is correct. A brain natriuretic peptide (BNP) level is a blood test specifically used to measure heart strain. Elevated BNP levels can indicate heart failure, making it a valuable diagnostic tool in assessing suspected CHF.

D) This choice is incorrect because a C-reactive protein (CRP) level is a marker of inflammation and is not specific to diagnosing CHF.
