A nurse on a postpartum unit is caring for a client. Exhibits Complete the following sentence by using the lists of options. The client is most likely experiencing by the client's dropdown as evidenced by the client’s dropdown.

Rationale for Correct Choices: Endometritis: Endometritis is a common postpartum infection of the uterine lining, often following cesarean birth, especially with risk factors like prolonged rupture of membranes and anemia. Clinical features include uterine tenderness, foul-smelling lochia, and fever, all of which are present in this case. Uterus and lochia assessment: A uterus that is tender and slightly elevated, with moderate dark brown, malodorous lochia, is a hallmark of endometritis. The boggy fundus that firms with massage also suggests poor involution, frequently associated with infection. Rationale for Incorrect Choices: Mastitis: While the client reports breast discomfort, mastitis typically presents with unilateral breast pain, localized redness, and flu-like symptoms. The findings here are more consistent with engorgement than with infectious mastitis. Pneumonia: The client has no respiratory distress, productive cough, or abnormal lung sounds (only slightly diminished bases), and oxygen saturation is normal. These signs are insufficient to support pneumonia. Fever: Although fever is present (38.2°C), it is a nonspecific symptom that could occur with any postpartum infection or inflammation. It supports infection but does not localize the source as definitively as the uterine and lochia findings. WBC count: The elevated WBC count (33,000/mm³) indicates infection or inflammation, but again, it is nonspecific. It supports the diagnosis but does not point solely to endometritis without clinical context from the uterus and lochia.
