A 4-week-old male infant is brought to the physician because of a 1-week history of refusing to finish all his bottle feeds and becoming irritable shortly after feeding. He has also spit up sour-smelling milk after most feeds. Pregnancy and delivery were uncomplicated, with the exception of a positive vaginal swab for group B streptococci 6 weeks ago, for which the mother received one dose of intravenous penicillin. The baby is at the 70th percentile for length and 50th percentile for weight. His temperature is 36.6°C (98°F), pulse is 180/min, respirations are 30/min, and blood pressure is 85/55 mm Hg. He appears lethargic. Examination shows sunken fontanelles and a strong rooting reflex. The abdomen is soft with a 1.5-cm (0.6-inch) nontender epigastric mass. Examination of the genitals shows a normally pigmented scrotum, retractile testicles that can be pulled into the scrotum, a normal-appearing penis, and a patent anus. Which of the following interventions would have been most likely to decrease the patient's risk of developing his condition?
