The nurse is assessing the placement of a nasogastric tube in a preterm infant. What assessment finding would confirm correct placement of the nasogastric tube into the stomach?

The tube is inserted to a depth from the ear to the tip of the nose to the umbilicus.

Aspiration produces a small quantity of light-yellow or light-green liquid.

A whooshing sound is auscultated in the epigastric area when air is introduced into the tube.

The infant cries loudly with insertion of the nasogastric tube.
