A nurse is educating a client about the risk factors for pulmonary embolism. Which statement made by the client indicates a correct understanding of the risk factors?

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.

A) Incorrect. Mild shortness of breath during activities may not be unusual, but sudden or severe shortness of breath should be reported.

B) Correct. Chest pain that worsens with deep breathing or coughing may indicate a worsening of the pulmonary embolism and should be reported immediately.

C) Incorrect. Mild swelling in the ankles is not typically a sign of a pulmonary embolism. However, severe leg swelling or pain should be evaluated.

D) Incorrect. An occasional cough with clear sputum is not necessarily a sign of a pulmonary embolism. However, if the cough becomes severe or is associated with other symptoms, it should be reported.
