A client asks a nurse if there are any lifestyle changes they can make to reduce the risk of developing a pulmonary embolism. What advice should the nurse provide?

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. While pain management is important, providing supplemental oxygen to address severe shortness of breath takes priority.

B) Incorrect. Initiating anticoagulant therapy is essential but may take some time to have an effect. Oxygen therapy should be provided immediately to address the client's oxygenation.

C) Correct. Providing supplemental oxygen is the priority intervention for a client with severe

shortness of breath to ensure adequate oxygenation.

D) Incorrect. Encouraging ambulation is not appropriate in a client with severe shortness of breath. Stabilizing the client's oxygenation and condition is the immediate concern.
