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. High-intensity exercise may not necessarily reduce the risk and could potentially increase the risk if it leads to prolonged immobility afterward.

B) Correct. Maintaining a healthy weight, regular physical activity, and avoiding smoking are known lifestyle factors that can reduce the risk of pulmonary embolism.

C) Incorrect. Lifestyle changes, as mentioned, can play a role in prevention.

D) Incorrect. While stress reduction is beneficial for overall health, it is not specifically linked to the prevention of pulmonary embolism.
