What is the first step in determining treatment for pulmonary embolism?

• A. Risk stratify into high, intermediate, or low risk
• B. Obtain CT angiography
• C. Oxygen supplementation
• D. Administer aspirin

Answer: (A)

Assessing risk category is the first step in deciding how to treat a pulmonary embolism because the treatment plan depends on how severely the PE is threatening the patient. The initial priority is to identify if the patient is hemodynamically unstable (shock or hypotension); that situation triggers urgent reperfusion therapy. If the patient is stable, the next move is to classify risk as high, intermediate, or low based on factors like right ventricular function, biomarker elevation, and overall clinical status. This risk stratification then guides whether standard anticoagulation is enough, or whether escalation to thrombolysis or more aggressive therapies is needed, and whether the patient can be treated as an outpatient or requires hospitalization. Oxygen and supportive care are important, but the categorization of risk is what primarily directs the treatment pathway. Aspirin is not the standard initial therapy for acute PE.
