A nurse is caring for a client who has a brain tumor. The client displays decorticate posturing in response to painful stimuli. Which of the following images illustrates decorticate posturing?

The first image illustrates decerebrate posturing (also known as extensor posturing). In this more severe posture, the arms are rigidly extended and adducted, the wrists are pronated, the fingers are flexed, and the legs are rigidly extended with plantar flexion. This is caused by damage to the brainstem at or below the red nucleus (midbrain) and indicates a worse prognosis. The second image illustrates decorticate posturing (also known as flexor posturing). In this posture, the client's arms are rigidly flexed and adducted (bent inward toward the chest), the fists are clenched, and the legs are extended and internally rotated. This is typically caused by damage to the corticospinal tracts above the red nucleus (above the midbrain).
