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.

C) Correct. Providing supplemental oxygen is the priority intervention for a client with severe
shortness of breath to ensure adequate oxygenation.

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.
