Final answer:
The nurse should place a sterile dressing and supplies at the newborn's bedside as the priority item to protect the exposed neural tissue and prevent infection in a newborn with myelomeningocele type spina bifida.
Step-by-step explanation:
The nurse should place a sterile dressing and supplies at the newborn's bedside as the priority item. Spina bifida is a birth defect of the spinal cord where the meninges and neural tissue protrude through the vertebral column. As a result, the newborn with myelomeningocele type spina bifida will require immediate medical attention and protection of the exposed neural tissue. Placing a sterile dressing and supplies at the bedside will help prevent infection and provide necessary care for the newborn.
