How does maternal hypertension impact FHR patterns?

• A. It enhances fetal heart rate stability
• B. It can lead to reduced blood flow and contribute to fetal distress patterns
• C. It has no effect on fetal heart rate
• D. It results in a consistent heart rate increase

Answer: (B)

Maternal hypertension can significantly impact fetal heart rate (FHR) patterns due to its effects on placental blood flow. When a mother has high blood pressure, it can cause changes in the vascular system, leading to reduced uteroplacental perfusion. This diminished blood flow can result in inadequate oxygen delivery to the fetus, which may manifest as fetal distress patterns. These distress patterns may include variable decelerations or even late decelerations in the fetal heart rate, indicating that the fetus is experiencing stress, potentially due to hypoxia or compromised circulation. Thus, the correlation between maternal hypertension and fetal heart rate patterns emphasizes the importance of monitoring and managing maternal health during pregnancy to ensure optimal fetal outcomes.
