Correct Answer is A

Explanation

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. "Avoid any form of physical activity to minimize the risk." B. "Maintain a diet high in cholesterol to prevent blood clots." C. "Completely eliminate all caffeine and alcohol from your diet." D. "Follow your healthcare provider's recommendations for anticoagulant therapy."

Correct Answer is D

Explanation

A) Incorrect. Avoiding all physical activity is not recommended. Clients should engage in appropriate physical activity, and the level of activity may be adjusted based on their condition.

B) Incorrect. A diet high in cholesterol is not a preventive measure for blood clots; in fact, it can contribute to cardiovascular risk factors.

C) Incorrect. While excessive caffeine and alcohol intake should be avoided, eliminating them completely is not a specific preventive measure for pulmonary embolism.

D) Correct. Following the healthcare provider's recommendations for anticoagulant therapy is crucial in preventing recurrent pulmonary embolism, especially in individuals with a history of the condition.
