The nurse is caring for a baby with esophageal atresia. On review of the mother's pregnancy history, which situation would the nurse identify as associated with the development of this condition?
Explanation & Rationale
Choice A rationale Bleeding at 32 weeks of pregnancy, often due to conditions like placenta previa or placental abruption, is not a known or direct etiological risk factor specifically associated with the embryonic maldevelopment that results in esophageal atresia. Esophageal atresia occurs early in gestation, generally before the 12th week, when the trachea and esophagus fail to separate properly from the foregut, which is unrelated to later-stage bleeding issues. Choice B rationale Failure to progress in labor is an obstetric complication that occurs late in the pregnancy and delivery process, often due to issues with the power, passenger, or pelvis. This labor complication has no causal relationship with the fetal development of esophageal atresia, which is a structural congenital malformation that arises during the first trimester of embryonic development. Choice C rationale Polyhydramnios, the presence of excessive amniotic fluid (amniotic fluid index > 24 cm), is strongly associated with esophageal atresia. The fetus normally swallows amniotic fluid, and if the esophagus is blind-ended or blocked (atresia), the fluid cannot pass into the gastrointestinal tract for absorption, leading to its accumulation in the amniotic sac. This is a crucial diagnostic clue for the condition. Choice D rationale Preeclampsia is a multisystem disorder of pregnancy characterized by new-onset hypertension and proteinuria after 20 weeks gestation. While it can impact fetal growth and health, preeclampsia is not scientifically linked as a specific risk factor or cause for the congenital structural abnormality of esophageal atresia, which involves failed organ separation during early embryonic life.
