The answer and the reasoning

B. Gastroschisis

Gastroschisis is a paraumbilical defect, usually to the right, with no sac and rarely any associated anomalies. Omphalocele has a covering membrane, is at the umbilicus and is associated with chromosomal and cardiac anomalies. Immediate care is a sterile wrap and fluid resuscitation.

    Correct. No sac with a paraumbilical defect is gastroschisis.

  • C. Umbilical hernia

    Umbilical hernia is covered by skin.

  • D. Bladder exstrophy

    Bladder exstrophy involves the lower abdomen and bladder.
