Final answer:
A newborn with a 5-minute APGAR score of 5 would require full resuscitation assistance, including measures such as providing oxygen and rubbing the baby's back. The APGAR score should be reassessed after the intervention.
Step-by-step explanation:
Based on the Apgar scoring criteria, a score of 5 at the 5-minute mark indicates that medical assistance may be needed for the newborn. Therefore, the appropriate nursing intervention would be full resuscitation assistance to stabilize the newborn. This may include providing oxygen, rubbing the baby's back, and any other necessary resuscitation measures. After providing the resuscitation assistance, it is important to reassess the APGAR score to monitor the newborn's progress and determine if additional interventions are needed.
