A nurse is caring for a client who is 24 hr postpartum. Which of the following findings should the nurse report to the provider?

A. WBC count 12,000/mm³: A mild elevation in white blood cell count is expected within the first few days postpartum as part of the normal inflammatory response due to the stress of labor and delivery.. A count of 12,000/mm³ is not alarming and does not necessarily indicate infection or a complication. B. Temperature 37.8°C (100°F): A low-grade temperature elevation within the first 24 hours postpartum is common due to hormonal shifts, dehydration, or exertion from labor. This finding would not immediately require provider notification unless it persists or rises higher. C. Respiratory rate 16/min: A respiratory rate of 16 breaths per minute is within normal adult limits and does not suggest respiratory distress or any postpartum complication, so no intervention is required for this finding. D. Hgb 8 g/dL: A hemoglobin level of 8 g/dL is significantly low and can indicate postpartum hemorrhage or significant blood loss. This degree of anemia should be reported promptly to the provider to assess the need for interventions such as blood transfusion or iron supplementation.
