A client suspected of having a pulmonary embolism complains of sudden chest pain and difficulty breathing. The nurse auscultates the client's chest and notes crackling sounds during inspiration. Which term describes these crackling sounds?

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.

A) Incorrect. Pulmonary angiography involves the injection of contrast dye into the pulmonary arteries, not the insertion of a scope into the lungs.

B) Correct. Remaining still during the procedure is crucial to obtain clear images, and the client should be educated about the importance of cooperation.

C) Incorrect. Allergies to contrast dye can be a concern, and the client should inform the healthcare team of any allergies to prevent potential adverse reactions.

D) Incorrect. Mild discomfort and chest pain are not common during pulmonary angiography and should not be expected. The procedure is typically done under local anesthesia, and any discomfort should be reported to the healthcare team.
