The nurse is assessing a primigravida at 39 weeks gestation during a weekly prenatal visit. Which finding is most important for the nurse to report to the healthcare provider (HCP)? Reference Range:Hemoglobin in pregnancy [greater than 11 g/dL (110 g/L)]

Rationale: A. Troubled by early morning heartburn: Heartburn is common in late pregnancy due to hormonal changes and pressure from the uterus. While uncomfortable, it is not an urgent concern and does not require immediate reporting. B. Fetal heart rate (FHR) of 200 beats/minute: A FHR of 200 bpm is significantly above the normal range (110–160 bpm) and may indicate fetal tachycardia, which can result from infection, maternal fever, or fetal distress. This requires immediate notification of the HCP. C. Maternal hemoglobin of 11.0 g/dL (110 g/L): This value is within the normal range for pregnancy and does not indicate anemia or require urgent intervention. D. Reports intermittent low back pain: Mild low back pain is common in late pregnancy due to postural changes and increased lumbar lordosis. While symptomatic relief may be needed, it is not an urgent finding requiring immediate HCP notification.
