Final answer:
The electrode for fetal monitoring should not be positioned on the baby's forehead, specifically over the fontanel, to prevent possible injury to soft tissues and bone structures.
Step-by-step explanation:
The electrode for fetal monitoring should not be placed on the baby's fontanel, which is the soft spot on the top of the head. In the choices provided, this corresponds to the forehead, since the anterior fontanel is located in this area. Therefore, the answer is c) Forehead.
It is crucial to avoid this area to prevent injury to the underlying soft tissue and bone development. Instead, the electrode is commonly placed on the occiput or back portion of the baby's head, where the bones are more fully developed and it is safer for attachment.
