Which of the following is NOT a cause of prolonged deceleration?

• A. Maternal seizure
• B. Cord prolapse
• C. Uterine hyperactivity
• D. Routine fetal monitoring

Answer: (D)

Routine fetal monitoring is not considered a cause of prolonged deceleration. Instead, it is a vital practice used to assess the fetal heart rate and identify any potential issues during labor. By continuously monitoring the fetus, healthcare providers can detect decelerations and other patterns in fetal heart rate, allowing for appropriate interventions to ensure the well-being of the baby.

In contrast, prolonged deceleration can occur due to various pathological conditions. Maternal seizures can lead to a lack of oxygen to the fetus, causing heart rate decelerations. Cord prolapse can mechanically obstruct blood flow, leading to significant drops in fetal heart rate. Uterine hyperactivity, or excessive uterine contractions, can also reduce oxygen delivery to the fetus, resulting in prolonged decelerations. Understanding these distinctions is crucial for effectively managing labor and ensuring fetal safety.
