When assessing a child's reflexes, the nurse places the child in the prone position and presses a thumb along the child's spine from sacrum to neck. the nurse finds that the child starts crying and urinates while flexing the extremities. which reflex is the nurse assessing in the child?

It will be the Perez Reflex.
