Final answer:
The correct action for a nurse transporting a newborn back to the parent's room following a procedure is to place the newborn in a bassinet and cover with a blanket, thereby helping to maintain a normal body temperature and provide comfort through swaddling.
Step-by-step explanation:
The question is about the proper care of a newborn after a procedure, inquiring about which actions should be taken by a nurse to ensure the newborn's well-being. Given that newborns can lose heat quickly due to their high surface-to-volume ratio, immature musculature, and limited fat for insulation, it is essential to maintain their body temperature. Option a, placing the newborn in the bassinet and covering with a blanket, would be the correct action as it helps maintain the baby's body temperature. Swaddling, which is mentioned in option d, is also a recommended practice for providing comfort and warmth to a newborn. Hence, the combined actions from option a and the relevance of swaddling from option d would be appropriate.
