Final answer:
Normal newborn weight loss can be as much as 10% in the first week, and the nurse should reassure the mother that an 8 oz loss is within the normal range.
Step-by-step explanation:
The most appropriate response by the nurse in this situation would be:
B. That is normal weight loss. Sometimes babies lose as much as 10% of the birth weight.
During the first days after birth, it's common for newborns to experience weight loss. A weight loss of up to 10% of the birth weight is considered within the normal range for newborns. This initial weight loss mainly involves the loss of excess fluid, meconium, and adjustment to feeding.
It's important for the nurse to reassure the mother that a moderate amount of weight loss in the early days after birth is a normal physiological process for newborns. This reassurance helps alleviate the mother's concerns and provides essential information about what to expect during this initial period. Unless there are other concerning symptoms or issues, such as inadequate feeding or signs of dehydration, suggesting intravenous infusion or supplementing with formula is generally not indicated based solely on the newborn's typical weight loss in the first few days after birth.
