Which postpartum finding is most urgent to assess first?

• A. Reports swelling in her right calf
• B. Lochia amount moderate
• C. Uterus firm and midline
• D. Temperature 99.0°F (37.2°C)

Answer: (A)

Unilateral swelling of a leg in the postpartum period is a red flag for deep vein thrombosis, and this matters most because a DVT can quickly lead to a dangerous pulmonary embolism. The postpartum state is highly prothrombotic, and immobility or vascular injury during delivery increases clot risk, so identifying a potential DVT promptly is crucial for preventing a life-threatening complication. That’s why this finding is prioritized for immediate assessment and further testing (such as a Doppler ultrasound) and urgent intervention if a clot is found. In comparison, a moderate amount of lochia can be expected as the uterus sheds its lining, a uterus that is firm and midline suggests good involution, and a temperature around 99.0°F is not typically alarming on its own, though fever would prompt further evaluation.
