The nurse compared the birth weight of a 3-day-old with her current weight and determined the infant had lost weight. What is the most appropriate intervention by the nurse?

A. Report the discrepancy to the pediatrician immediately: While significant or excessive weight loss should be reported, mild physiologic weight loss in the first few days of life is expected. Immediate reporting is not necessary if the loss is within the normal range of 5–10% of birth weight. B. Decrease the interval between the infant's feedings: Newborns typically lose some weight in the first 3–5 days due to fluid shifts and limited intake. Increasing the frequency of feedings helps ensure adequate caloric intake and promotes gradual weight gain, supporting healthy growth and hydration. C. Do nothing because this is a normal occurrence: Although some weight loss is normal, the nurse should take action to support feeding and monitor ongoing weight trends rather than ignoring the loss entirely. D. Try feeding the infant a different type of formula: Changing formula is not indicated unless the infant has feeding intolerance or a medical reason. The initial intervention should focus on optimizing feeding frequency and technique rather than switching formula.
