Final answer:
The nurse communicates the low fetal heart rate to indicate potential fetal distress, especially critical in a shoulder dystocia situation, prompting immediate action to prevent complications.
Step-by-step explanation:
It is important for the nurse to communicate that the fetal heart rate is 90 bpm with minimal variability after the delivery of the fetal head as this could suggest potential fetal distress. During labor and delivery, fetal heart rate is an essential indicator of the fetus's well-being. Normal fetal heart rate is between 110 to 160 bpm, hence a rate of 90 bpm is concerning. In the context of shoulder dystocia, a condition where the baby's shoulder becomes trapped after the head is delivered, this low heart rate could indicate that the baby is not receiving enough oxygen due to the compression of the umbilical cord or other circulatory compromise. Immediate and clear communication by the nurse is vital for prompt action by the healthcare team to resolve the dystocia and alleviate fetal distress, potentially preventing serious or life-threatening complications for the newborn.
