A nurse is reinforcing teaching for a client who presents with a pulmonary embolism. Which of the following information should the nurse provide?

A. Treatment is not needed if the client is hemodynamically stable: Even if a client is stable, a pulmonary embolism can lead to serious complications such as right ventricular strain, recurrent emboli, or sudden deterioration. Treatment is still necessary to prevent progression and complications. B. Treatment is not needed if the client is asymptomatic: Pulmonary emboli can be life-threatening even in the absence of symptoms. Anticoagulation or other interventions are required to reduce the risk of clot propagation and potentially fatal outcomes. C. Treatment is needed for all clients who have a pulmonary embolism: All clients diagnosed with a pulmonary embolism require treatment, typically anticoagulation therapy, regardless of symptom severity or stability. Treatment prevents further clot formation, reduces mortality, and minimizes complications. D. Treatment is not needed if the pulmonary embolism is intermediate: The size or classification of the embolism does not eliminate the need for treatment. Even intermediate pulmonary emboli require anticoagulation and close monitoring to prevent worsening or recurrence.
