Computed tomography angiography (CTA)

Magnetic resonance imaging (MRI)

Chest X-ray

Electrocardiogram (ECG)

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is B

Explanation

A) Incorrect. Intravenous antibiotics are not typically used as the initial treatment for pulmonary embolism. Antibiotics are used to treat bacterial infections, not blood clots.

B) Correct. Anticoagulant therapy, such as heparin or low-molecular-weight heparin, is often the initial treatment for pulmonary embolism to prevent further clot formation and reduce the risk of complications.

C) Incorrect. Emergency surgical removal of the embolism is considered in severe cases but is not the common initial treatment approach.

D) Incorrect. Placement of a chest tube for drainage is not a standard treatment for pulmonary embolism; it is used for conditions involving pleural effusion or pneumothorax.

A. Aspirin B. Warfarin (Coumadin) C. Insulin D. Nitroglycerin

Correct Answer is B

Explanation

A) Incorrect. Aspirin is an antiplatelet agent, not a long-term anticoagulant, and it is typically not used as the primary treatment for pulmonary embolism.

B) Correct. Warfarin (Coumadin) is commonly used for long-term anticoagulation in individuals with a history of recurrent pulmonary embolism. It helps prevent the formation of new blood clots.

C) Incorrect. Insulin is used to manage blood sugar levels in diabetes and is not a medication for anticoagulation.

D) Incorrect. Nitroglycerin is used to relieve chest pain (angina) related to heart conditions but is not an anticoagulant.
