Which finding would most urgently indicate postpartum infection requiring evaluation and intervention?

• A. Mild fatigue with no fever
• B. Localized breast tenderness without redness
• C. Fever with uterine tenderness
• D. Headache with normal blood pressure

Answer: (C)

Fever with uterine tenderness signals a uterine infection (endometritis) that must be evaluated and treated right away. After delivery, an infected uterus can deteriorate quickly, so the combination of systemic fever and a tender uterus points to a significant infection requiring prompt antibiotics (often IV) and closer monitoring to prevent progression to sepsis.

Mild fatigue without fever is common in the postpartum period and alone does not indicate infection. Localized breast tenderness without redness suggests engorgement or simple breast discomfort rather than an infectious process with systemic signs. Headache with normal blood pressure could be a benign postpartum headache or tension, and the normal BP makes conditions like preeclampsia less likely; it doesn’t point to a postpartum uterine infection.
