Final answer:
A baby that can suck and swallow well but then chokes might have a tracheoesophageal fistula, an abnormal connection that allows food to enter the airway, causing choking.
Step-by-step explanation:
If a baby can suck and swallow well, but then chokes, the condition that should be suspected is c. Tracheoesophageal fistula. This condition involves an abnormal connection between the trachea (windpipe) and the esophagus (the tube that carries food to the stomach). Normally during swallowing, the body has mechanisms to prevent food from entering the airways.
However, with tracheoesophageal fistula, these mechanisms are compromised, and the baby may choke as a result. Other conditions such as a. Esophageal atresia, b. Gastroesophageal reflux, or d. Tetralogy of Fallot are less likely to present with these specific symptoms of choking immediately after swallowing.
