Exhibits A nurse is reviewing the medical record of a school-age child who has cystic fibrosis. Which of the following findings should the nurse report to the provider? (Click on the exhibit tabs for additional information about the client. There are three tabs that contain separate categories of data.)

A. Oxygen saturation: An oxygen saturation of 95% is within the normal range for a school-age child and acceptable for a client with cystic fibrosis, who may have mild baseline respiratory compromise. B. WBC count: A WBC count of 9,600/mm³ is within the normal pediatric range (5,000–10,000/mm³). It does not suggest acute infection or bone marrow suppression, so it is not a reportable finding. C. HbA1c: An HbA1c of 8.5% is significantly elevated above the normal range (4%–5.9%). This indicates poor glycemic control, suggesting cystic fibrosis–related diabetes, a common complication. This requires provider notification for further evaluation and management. D. Heart rate: A heart rate of 98/min is within the normal range for school-age children (75–118/min). It does not indicate acute distress or cardiac complications, so it does not warrant immediate reporting.
