A client with suspected pulmonary embolism is undergoing a ventilation-perfusion (V/Q) scan. What is the purpose of this imaging test?

To visualize the heart's electrical activity

To assess lung function and oxygenation

To measure blood clotting time

To evaluate kidney function

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is C

Explanation

A) Incorrect. tPA therapy is not primarily used for pain relief but rather for clot dissolution.

B) Incorrect. While improving lung function and oxygenation is a goal in treating pulmonary embolism, tPA's primary purpose is to dissolve existing blood clots.

C) Correct. tPA (tissue plasminogen activator) is a thrombolytic agent used to break down and dissolve existing blood clots in the pulmonary arteries, improving blood flow.

D) Incorrect. tPA is not used to prevent the formation of new blood clots but rather to treat existing clots.

A. "Sitting for extended periods while traveling doesn't increase my risk of pulmonary embolism." B. "Being on long-term anticoagulant therapy raises my risk of developing pulmonary embolism." C. "Having a sedentary lifestyle and being immobile for extended periods can increase my risk." D. "Pulmonary embolism is not associated with recent surgery or trauma."

Correct Answer is C

Explanation

A) Incorrect. Prolonged sitting during travel, especially on long flights, can increase the risk of pulmonary embolism due to immobility.

B) Incorrect. Long-term anticoagulant therapy is often prescribed to reduce the risk of pulmonary embolism, not increase it.

C) Correct. Prolonged immobility, such as sitting for long hours or bed rest, is a significant risk factor for pulmonary embolism.

D) Incorrect. Recent surgery, trauma, or hospitalization can increase the risk of developing pulmonary embolism due to factors such as immobility and altered blood clotting.
