Final answer:
The nurse should document the findings regarding the baby's weight.
Step-by-step explanation:
A newborn male is admitted to the nursery weighing 10 pounds, 2 ounces, which is 2 pounds more than the birth weight of any of his siblings. In this case, the nurse should document the findings. Monitoring a newborn's weight is important to ensure proper growth and development. It is normal for newborns to lose some weight in the first week, but they should start gaining weight rapidly after that.
