A client with a history of smoking asks the nurse about the relationship between smoking and the risk of pulmonary embolism. How should the nurse explain this relationship?
"Smoking has no impact on the risk of pulmonary embolism."
"Smoking can lower the risk of pulmonary embolism due to improved lung function."
"Smoking increases the risk of pulmonary embolism due to blood vessel damage and clot formation."
"Pulmonary embolism risk is only related to the duration of smoking, not the amount."
The Correct Answer is C
A) Incorrect. Smoking can influence the risk of pulmonary embolism, typically increasing it.
B) Incorrect. Smoking is generally associated with increased pulmonary embolism risk, not reduced risk.
C) Correct. Smoking can damage blood vessels and promote clot formation, contributing to the risk of
pulmonary embolism.
D) Incorrect. Both the duration and amount of smoking can impact pulmonary embolism risk.

Correct Answer is B
Explanation
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.
