A client recovering from major surgery asks a nurse about the risk of developing a pulmonary embolism postoperatively. What should the nurse include in the explanation of post-surgery risk factors?

A) Incorrect. Surgery, especially major procedures, can increase the risk of pulmonary embolism.

B) Incorrect. The risk of pulmonary embolism is often higher after major surgeries, not limited to minor procedures.

C) Correct. Major surgeries and procedures carry a higher risk of pulmonary embolism due to factors like immobility and surgical trauma.

D) Incorrect. While genetics can play a role in clotting disorders, surgery remains a significant risk factor for pulmonary embolism.

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.
