A nurse is caring for a client who has developed pulmonary embolism (PE). Which of the following diagnostic tests should the nurse anticipate the provider to prescribe to confirm the client's condition?(Select All that Apply.)

D-dimer blood test

Complete blood count (CBC)

CT scan

Chest x-ray

Lung ventilation and perfusion scan (VQ scan)

Answer and Explanation

Correct Answer : A,C,E

A. D-dimer blood test - A D-dimer test measures clot breakdown products in the blood. Elevated levels suggest the presence of an abnormal blood clot, such as in PE, although it is not specific.

B. Complete blood count (CBC) - A CBC is not typically used to diagnose PE. It may be ordered to check for other conditions or as part of the overall health assessment, but it doesn't confirm PE.

C. CT scan - A CT pulmonary angiography is the gold standard for diagnosing PE. It provides detailed images of the blood vessels in the lungs.

D. Chest x-ray - A chest x-ray is not diagnostic for PE. It is often performed to rule out other causes of the client’s symptoms (e.g., pneumonia, pneumothorax) but does not confirm the presence of a pulmonary embolism.

E. Lung ventilation and perfusion scan (VQ scan)
A VQ scan is another diagnostic tool for PE, especially in clients who cannot tolerate contrast dye required for CT scans. It assesses the ventilation and perfusion of the lungs and identifies mismatches suggestive of PE.
