The nurse is caring for an infant with abdominal contents protruding out approximately at the location of the umbilicus. What is the primary mechanism used to differentiate between omphalocele or gastroschisis?
1. With omphalocele, the abdominal contents are covered with a sac; with gastroschisis, the abdominal contents are not covered by a sac.
2. With omphalocele, the abdominal contents are not covered with a sac; with gastroschisis, the abdominal contents are covered by a sac.
3. With omphalocele, the abdominal contents protrude to the right of an intact umbilical cord; with gastroschisis, the abdominal contents protrude into the base of the umbilical cord.
4. With omphalocele, the abdominal contents protrude into the base of the umbilical cord; with gastroschisis, the abdominal contents protrude to the right of an intact umbilical cord.
Correct Answer: 4
Rationale 1: If the abdominal contents are covered by a sac, it is omphalocele. However, if the abdominal contents are not covered by a sac, it could be either omphalocele or gastroschisis. The better way to differentiate between omphalocele and gastroschisis is that the abdominal contents protrude into the base of the umbilical cord in omphalocele but protrude to the right of the umbilical cord in gastroschisis.
Rationale 2: If the abdominal contents are covered by a sac, it is omphalocele. However, if the abdominal contents are not covered by a sac, it could be either omphalocele or gastroschisis. The better way to differentiate between omphalocele and gastroschisis is that the abdominal contents protrude into the base of the umbilical cord in omphalocele but protrude to the right of the umbilical cord in gastroschisis.
Rationale 3: This is the opposite description of gastroschisis and omphalocele. With omphalocele, the abdominal contents protrude into the base of the umbilical cord; with gastroschisis, the abdominal contents protrude to the right of an intact umbilical cord.
Rationale 4: This is a correct way to differentiate between omphalocele and gastroschisis.
