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.

Correct Answer is C
Explanation
A) Incorrect. While surgical trauma can be a risk factor, it is not solely associated with incisions and scars.
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.
Correct Answer is C
Explanation
A) Incorrect. A complete blood count (CBC) provides information about the composition of blood cells but is not specific to pulmonary embolism.
B) Incorrect. Arterial blood gas (ABG) analysis helps assess oxygen and carbon dioxide levels but is not a primary test for diagnosing pulmonary embolism.
C) Correct. The D-dimer assay measures a substance released when a blood clot breaks up. Elevated D-dimer levels can suggest the presence of a blood clot, but it is not specific to pulmonary embolism.
D) Incorrect. Creatine kinase (CK) levels are used to assess muscle damage and are not a primary test for diagnosing pulmonary embolism.
