Final answer:
The nurse should provide immediate medical assistance to the newborn as the symptoms indicate distress. Apgar scoring system helps assess the well-being of the newborn. Medical attention is crucial in emergency situations.
Step-by-step explanation:
The best thing for the nurse to do in this situation is to provide immediate medical assistance to the newborn. The infant's symptoms, including a heart rate of 100, 0 respirations, limpness, and blueness, indicate that the baby may be in distress. These signs may suggest a need for resuscitation or stabilization.
According to the Apgar scoring system, heart rate and respiration are critical indicators of a newborn's well-being. Normally, a newborn should have a total score of 8 or above, but a score lower than 7 at the 5-minute mark may require medical assistance. A score below 5 indicates an emergency situation.
In this case, immediate medical attention should be sought to provide the necessary interventions and support for the newborn.
