Correct Answer is B

Explanation

A) Incorrect. Visualizing the heart's electrical activity is typically done with an electrocardiogram (ECG), not a V/Q scan.

B) Correct. A ventilation-perfusion (V/Q) scan is used to assess lung function and oxygenation and to detect areas of the lung where blood flow and air ventilation do not match, which can indicate a pulmonary embolism.

C) Incorrect. Measuring blood clotting time is typically done using coagulation tests such as prothrombin time (PT) or activated partial thromboplastin time (aPTT).

D) Incorrect. Evaluating kidney function is not the primary purpose of a V/Q scan.

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.
