The nurse is caring for an infant with myelomeningocele scheduled for surgical closure in the morning. Which intervention should the nurse plan for the care of the myelomeningocele sac?

A) Open to air
B) Covered with a sterile, moist, nonadherent dressing
C) Reinforcement of the original dressing if drainage noted
D) A diaper secured over the dressing

Before surgical closure, the myelomeningocele is prevented from drying by the application of a sterile, moist, nonadherent dressing over the defect. The moistening solution is usually sterile normal saline. Dressings are changed frequently (every 2 to 4 hours), and the sac is closely inspected for leaks, abrasions, irritation, and any signs of infection. The sac must be carefully cleansed if it becomes soiled or contaminated. The original dressing would not be reinforced but changed as needed. A diaper is not placed over the dressing because stool contamination can occur.
