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.
