A parent calls a clinic and reports to a nurse that his 2-month-old infant is hungry more than usual but is projectile vomiting immediately after eating. Which of the following responses should the nurse make?

A. Switching formula is not the first intervention, as projectile vomiting in an infant can indicate a more serious condition such as pyloric stenosis, which requires medical evaluation. B. Oral rehydration solution may be needed if the infant is dehydrated, but the cause of vomiting must be assessed first. C. While burping can reduce gas and discomfort, it is unlikely to resolve projectile vomiting, which may be due to a more serious underlying condition. D. Bringing the baby to the clinic is the most appropriate action, as projectile vomiting can be a sign of pyloric stenosis or another serious condition that requires prompt medical attention.
