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
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.

B) Incorrect. The risk of pulmonary embolism after surgery is not low, and specific factors do contribute to the risk.
C) Correct. Prolonged immobility, surgical trauma, and changes in blood clotting are common risk factors for post-surgery pulmonary embolism.
D) Incorrect. Excessive fluid intake during recovery is not a primary risk factor for post-surgery pulmonary embolism.
