A nurse is assessing a newborn who has Erb-Duchenne palsy. Which of the following findings should the nurse expect?

A. Erb-Duchenne palsy involves injury to the upper brachial plexus, resulting in weakness or paralysis of the affected arm and an absent Moro reflex on that side. B. Cleft palate is unrelated to Erb-Duchenne palsy. C. The Babinski reflex is a neurological test of the lower limbs and is not affected by this condition. D. Difficulty sucking and swallowing is not typical of Erb-Duchenne palsy but may be related to other cranial nerve injuries.
