MDC3 Practice Test

The key idea is that suspected pulmonary embolism requires immediate stabilization of breathing and rapid escalation of care. In a DVT patient with chest pain and shortness of breath, the top priority is to ensure adequate oxygenation and quickly mobilize the team for urgent assessment and treatment. Administering supplemental oxygen helps correct hypoxemia from the V/Q mismatch caused by a PE, supporting tissue oxygen delivery as the patient is watched for potential deterioration. Activating a rapid-response team brings in the necessary resources—monitors, IV access, and rapid diagnostic options like imaging—to confirm the diagnosis and implement therapy as soon as it’s safe. Chest X-ray can be helpful for ruling out other causes of chest symptoms, but it does not diagnose PE and won’t by itself treat the situation. A diuretic isn’t addressing the underlying embolic problem and could worsen hemodynamics if fluids are not appropriately managed. Starting anticoagulation is important in PE management, but it is typically considered after initial stabilization and assessment of contraindications; the immediate action focuses on ensuring oxygenation and urgent escalation so definitive therapy can be delivered promptly.
