A three-month-old, developmentally-delayed infant was admitted to the pediatrics unit. The nurse evaluates the infant for manifestations of cerebral palsy. Which of the following would the nurse note as a sign of CP?

Exaggerated arching of the neck

Explanation

•A child with cerebral palsy may show opisthotonic posturing (exaggerated arching of the back) and rigidity.

•Increased or decreased resistance to passive movement is a sign of abnormal muscle tone, which is typical of children with cerebral palsy. When pulled to a sitting position, the child with CP may extend his/her entire body, rigid and unbending at the hip and knee joints.

•Children with cerebral palsy often have exaggerated reflexes due to an upper motor neuron lesion.

•Head circumference measurement less than the 50th percentile is a normal finding for a three-month-old infant.

•Slight head lag is expected in a three-month-old infant.
