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)
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.
