Final answer:
The feeding tube can be used for feeding five to seven days after the surgery.
Step-by-step explanation:
A nurse should respond by saying, "Feedings can begin in five to seven days." The statement is correct because after surgery for placement of a gastrostomy tube, it takes about five to seven days to allow healing of the incision before the tube can be used for feeding. During this time, the tube is used to drain stomach contents and air. After the healing process, the infant can start receiving feedings through the gastrostomy tube.
