A client asks a nurse about the process that leads to a pulmonary embolism. How should the nurse explain the pathophysiology of pulmonary embolism?

"It occurs when bacteria enter the lungs and cause an infection, leading to blockage of the blood vessels."

"A pulmonary embolism happens when a blood clot forms in the lungs and blocks the flow of blood."

"It's the result of prolonged exposure to environmental toxins, which gradually damage the lung tissue."

"Pulmonary embolism is caused by chronic inflammation in the airways, leading to restricted airflow."
