The nurse is preparing to administer a formula feeding by nasogastric tube (NGT) to a 2-month-old. Which intervention should the nurse implement?

A. Measure and discard residual gastric contents before feeding. Measuring residuals is a routine practice to ensure the stomach is empty, but it is not the priority in this situation unless the residual volume is significant. B. Use the syringe plunger to push formula at a rate of 5 mL/minute. The formula should be administered gradually, but forcing it with a plunger could cause discomfort or complications. C. Hold the infant with head and shoulders slightly elevated. This position helps prevent aspiration and promotes better digestion and comfort during feeding. D. Microwave refrigerated formula to room temperature. Microwaving formula is not recommended, as it can cause uneven heating and create hot spots that could burn the infant's mouth. The formula should be warmed in a safe manner, such as with a bottle warmer.
