Final answer:
If the baby is breathing and has a heart rate of at least 100 BPM but is Cyanotic, oxygen should be administered to resolve the lack of oxygen indicated by the blue skin color. CPR is not immediately necessary as the heart rate is within the normal range.
Step-by-step explanation:
If the baby is breathing and the heart rate (HR) is at least 100 BPM but the baby is Cyanotic, the correct response would be A) Administer oxygen. Cyanosis, characterized by the blue color of the skin due to a lack of oxygen, can be a sign of respiratory distress or inadequate oxygenation despite a normal heart rate. Since the heart rate is above 100 BPM, it falls within the normal range as per the Apgar score criteria, making immediate CPR unnecessary. However, continued monitoring and assessment are essential to ensure that the cyanosis resolves and the baby's condition does not worsen. If the baby's condition does not improve with oxygen administration or if any other concerning signs develop, medical personnel may need to reassess and take additional action to stabilize the newborn.
