Final answer:
When cutting the umbilical cord, the crucial factor to check for is cord pulsation to determine if the blood is still flowing, indicating the right time to clamp and cut the cord.
Step-by-step explanation:
What to Check When Cutting the Umbilical Cord
When cutting the umbilical cord, it is essential to check for cord pulsation. The cord's pulsation indicates that blood is still flowing between the baby and the placenta. In most practices, the umbilical cord is clamped and cut after the pulsation ceases, indicating the natural occlusion of the umbilical vessels as the Wharton's jelly within the cord swells in response to a lower temperature and the blood vessels constrict. This process collapses the umbilical blood vessels, after which they will become fibrotic remnants and serve different functions in the mature circulatory system.
Blood pressure, oxygen saturation, and pulse rate are also monitored in newborns but are not directly related to the timing of when to cut the umbilical cord. Instead, these parameters are part of the overall assessment of the newborn's condition, for instance, during the Apgar scoring system that assigns scores for skin color, heart rate, reflex, muscle tone, and respiration to indicate how well the baby has transitioned from the womb.
