In a client with deep vein thrombosis, which early sign/symptom would warrant immediate reporting for potential pulmonary embolism?

• A. Tachycardia with tachypnea
• B. Restlessness and dizziness
• C. Pain in the lower right leg
• D. A positive Homan's sign

Answer: (B)

Pulmonary embolism can develop quickly when a clot from a deep vein travels to the lungs, so signs that signal sudden changes in oxygen delivery are urgent red flags. Restlessness and dizziness reflect potential hypoxemia and cerebral hypoperfusion from an acute PE, so they prompt immediate reporting and assessment. While tachycardia with tachypnea can occur with PE, the combination of restlessness and dizziness more clearly indicates a dangerous perfusion change needing rapid action. Pain in the lower leg points to the original DVT, not an immediate PE concern, and a positive Homan’s sign is not a reliable indicator of PE.
