A client presents to the emergency department with suspected pulmonary embolism. What blood test can help assess the likelihood of pulmonary embolism and its severity?

A.

Complete blood count (CBC)

B.

Arterial blood gas (ABG) analysis

C.

D-dimer assay

D.

Creatine kinase (CK) levels

Answer and Explanation

The Correct Answer is C

A) Incorrect. A complete blood count (CBC) provides information about the composition of blood cells but is not specific to pulmonary embolism.

B) Incorrect. Arterial blood gas (ABG) analysis helps assess oxygen and carbon dioxide levels but is not a primary test for diagnosing pulmonary embolism.

C) Correct. The D-dimer assay measures a substance released when a blood clot breaks up. Elevated D-dimer levels can suggest the presence of a blood clot, but it is not specific to pulmonary embolism.

D) Incorrect. Creatine kinase (CK) levels are used to assess muscle damage and are not a primary test for diagnosing pulmonary embolism.
