A nurse is caring for a female client, age 36, in the postpartum unit following a scheduled cesarean birth 12 hours ago. Complete the following sentence by using the lists of options. The client is at greatest risk for developing __________ as evidenced by the client’s __________.

The client is at greatest risk for developing Endometritis as evidenced by the client’s Lochia characteristics. Rationale for correct answers: Endometritis is a postpartum uterine infection commonly occurring after cesarean birth due to ascending bacterial contamination. The client’s foul-smelling lochia is a hallmark sign, indicating infection of the uterine lining. Normally, lochia is odorless and changes from red to serous and then to white over weeks postpartum. The elevated WBC count (18,000/mm³; normal 5,000–15,000/mm³) supports infection but is nonspecific. The firm uterine tone reduces likelihood of postpartum hemorrhage. Urinalysis positive for bacteria suggests UTI but does not explain uterine signs. Hence, lochia changes are the most direct indicator of endometritis. Rationale for incorrect Response 1 answers: Postpartum hemorrhage typically involves heavy bleeding, uterine atony, or a rapidly dropping hematocrit, none of which is reported here. Urinary tract infection is suggested by urinalysis but does not account for uterine tenderness or foul lochia. Deep vein thrombosis would present with limb swelling, pain, and possible fever but no uterine or lochia changes. Rationale for incorrect Response 2 answers: Urinalysis positive for bacteria points to UTI but not uterine infection. Elevated WBC count indicates infection or inflammation but lacks specificity for endometritis versus other infections. Uterine tone is firm here, making hemorrhage or uterine atony unlikely and less relevant to infection diagnosis. Take home points: Endometritis often presents postpartum with foul-smelling lochia and elevated WBC. Foul-smelling lochia is a critical clinical sign distinguishing endometritis from other postpartum complications. Positive urinalysis suggests UTI, a separate postpartum infection that requires differentiation. Uterine tone helps rule out hemorrhage and guides diagnosis of infection versus atony.
