A nurse is caring for a client with suspected pulmonary embolism who is undergoing diagnostic testing. What diagnostic test is often used as an initial screening tool for pulmonary embolism?

Computed tomography angiography (CTA)

Magnetic resonance imaging (MRI)

Chest X-ray

Electrocardiogram (ECG)

Answer and Explanation

The Correct Answer is A

A) Correct. Computed tomography angiography (CTA) is often used as an initial screening tool for pulmonary embolism, as it provides detailed images of the pulmonary arteries.

B) Incorrect. Magnetic resonance imaging (MRI) may be used in some cases but is less commonly employed as an initial screening tool for pulmonary embolism.

C) Incorrect. Chest X-ray is typically not sensitive enough to diagnose pulmonary embolism directly but may show other related findings, such as an enlarged heart or lung abnormalities.

D) Incorrect. Electrocardiogram (ECG) may help identify signs of right heart strain or dysfunction caused by a pulmonary embolism but is not a primary diagnostic tool for detecting emboli in the pulmonary arteries.

Correct Answer is D

Explanation

A) Incorrect. Chest X-rays can show certain abnormalities but are not the primary diagnostic tool for pulmonary embolism.

B) Incorrect. Electrocardiograms (ECGs) are used to assess heart rhythm and electrical activity but are not used to diagnose pulmonary embolism.

C) Incorrect. Magnetic resonance imaging (MRI) may be used in some cases, but CTPA is the preferred test for diagnosing pulmonary embolism.

D) Correct. Computed tomography pulmonary angiography (CTPA) is the gold standard for diagnosing pulmonary embolism as it can visualize blood clots in the pulmonary arteries.

A. The procedure involves inserting a scope into the lungs. B. The client should remain still during the procedure to avoid complications. C. Allergies to contrast dye will not affect the procedure. D. Mild discomfort and chest pain during the procedure are common and should be expected.

Correct Answer is B

Explanation

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.
