A nurse is assessing a postpartum client 48 hours after cesarean delivery. Which assessment finding would be the priority concern indicating a possible postpartum infection?

Temperature >100.4°F after 24 hours postpartum with systemic symptoms indicates infection requiring immediate attention. Other findings are normal postpartum variations.

Clinical Reasoning & Priority Setting

This question tests your ability to differentiate between expected postpartum changes and findings that signal a potentially serious complication. After a cesarean delivery, the nurse must be vigilant for signs of infection, as surgical incisions and the uterine cavity provide direct pathways for pathogens.

The priority concern is a temperature of 101.2°F (38.4°C) with chills and malaise. In the postpartum period, a low-grade fever can sometimes occur due to dehydration or the normal inflammatory response, particularly with breast engorgement. However, a temperature of 100.4°F (38.0°C) or higher after the first 24 hours, especially when accompanied by systemic symptoms like chills and malaise, is a cardinal sign of postpartum infection ^[1]. The US has a significant rate of postpartum complications, and the emergency department is often the primary access point for urgent care during this vulnerable period, making early recognition of such signs critical ^[1]. This presentation raises immediate concern for endometritis, a well-described cause of postdelivery morbidity ^[2], or a surgical site infection. The combination of a significant fever and systemic symptoms indicates a systemic inflammatory response that requires prompt investigation and intervention to prevent maternal morbidity [1,2].

Analysis of Other Options

- Lochia rubra with small clots and mild cramping is an expected finding at 48 hours postpartum. The cramping is associated with uterine involution, and small clots are common as the uterus contracts and sheds its lining.
- Breast tenderness with slight engorgement is a normal physiological process as milk production transitions from colostrum to mature milk around this time. While engorgement can cause a mild, transient temperature elevation, it would not typically cause a fever of 101.2°F with chills.
- Perineal edema with mild discomfort during urination is an expected finding after a vaginal delivery, but this client had a cesarean delivery. Even if she labored beforehand, localized perineal discomfort without fever or other signs of infection is not the priority over a systemic febrile response. The fever and chills signal a systemic process, which takes precedence over localized discomfort in the nursing assessment hierarchy.
