The nurse is assessing a first day postpartum client. Which finding is most indicative of a postpartum infection?

A. A moderate amount of foul-smelling lochia can indicate an infection, especially if accompanied by other signs such as fever or abdominal pain. B. Blood pressure within normal range is not indicative of postpartum infection. C. While an elevated temperature can be a sign of infection, it's not specific enough on its own. D. A high white blood count can indicate infection, but it's not as specific as the presence of foul-smelling lochia in the postpartum period.
