Final answer:
Complications that a nurse should be alert for in a 6-day-old preterm infant include meconium ileus, duodenal atresia, imperforate anus, and necrotizing enterocolitis.
Step-by-step explanation:
In a 6-day-old preterm infant, the nurse should be alert for complications such as:
- Meconium ileus: This is a blockage in the intestines due to thick meconium, the baby's first stool. It can lead to abdominal distension and vomiting.
- Duodenal atresia: This is a condition where the duodenum, the first part of the small intestine, is blocked. It can cause feeding problems and abdominal swelling.
- Imperforate anus: This is a birth defect where the anus does not have an opening. It can result in difficulty passing stool.
- Necrotizing enterocolitis: This is a serious condition where the intestines become inflamed and can lead to tissue death. It can cause symptoms like feeding intolerance, abdominal distension, and bloody stools.
