Where should a fetal spiral electrode be applied?

• A. On the fetal face
• B. On the fetal scalp or buttocks
• C. On the fetal fontanelles
• D. On the fetal genitals

Answer: (B)

The correct application of a fetal spiral electrode is on the fetal scalp. This method is used to obtain a continuous fetal heart rate monitoring and provides accurate information about the fetal heart rate, which is crucial during labor. The scalp provides a good location for this electrode because it allows for consistent contact with the fetal heart, minimizing the risk of artifacts that can occur with external monitoring methods. While some other body parts, such as the buttocks, might be considered in broader discussions of fetal positioning, the scalp is the preferred site because it ensures the electrode stays in position during the various movements that occur during labor. In contrast, areas such as the genitals or fontanelles would not provide suitable surfaces for monitoring, and applying the electrode to the face raises concerns about both accuracy and potential injury. Thus, using the fetal scalp as the site for the spiral electrode aligns with best practices in fetal health surveillance.
