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 A
Explanation
A) Correct. Smoking cessation is an important lifestyle modification to reduce the risk of recurrent pulmonary embolism. Smoking is a risk factor for blood clot formation.
B) Incorrect. Limiting physical activity is not recommended, as moderate physical activity can be beneficial. However, strenuous activity may need to be adjusted depending on the individual's condition and treatment.
C) Incorrect. A high-sodium diet is not recommended, as excessive sodium intake can contribute to hypertension, which is a risk factor for blood clots.
D) Incorrect. Avoiding vaccinations is not relevant to the prevention of pulmonary embolism. Vaccinations are essential for preventing certain infections.
Correct Answer is D
Explanation
A) Incorrect. Chest X-rays can show certain abnormalities but are not the primary diagnostic tool for pulmonary embolism.
B) Incorrect. Electrocardiograms (ECGs) are used to assess heart rhythm and electrical activity but are not used to diagnose pulmonary embolism.
C) Incorrect. Magnetic resonance imaging (MRI) may be used in some cases, but CTPA is the preferred test for diagnosing pulmonary embolism.
D) Correct. Computed tomography pulmonary angiography (CTPA) is the gold standard for diagnosing pulmonary embolism as it can visualize blood clots in the pulmonary arteries.
