امرأة عمرها ٣٢ سنة بعد عملية قيصرية بيومين، عندها ألم وتورم في الساق اليسرى، وفجأة صار عندها ضيق نفس. النبض ١٢٠، والتشبع ٨٩٪. ما التصرف الأول؟

A 32-year-old two days after caesarean has a painful swollen left leg and suddenly becomes breathless. HR 120, SpO2 89%. What is the first action?

1. Oxygen and urgent escalation for possible PE
2. Reassure her it is postnatal anxiety
3. Massage the swollen leg
4. Brisk walking to improve circulation

Answer: A) Oxygen and urgent escalation for possible PE. The postpartum period is high risk for clots; sudden dyspnoea with leg swelling is PE until proven otherwise, needing oxygen, assessment and anticoagulation.
