Injury to the brachial plexus during birth

Congenital heart defect

Underdeveloped lungs

Verified step by step guidance

Understand the context: Erb's palsy is a condition often caused by an injury to the brachial plexus, which is a network of nerves near the neck that controls the muscles of the shoulder, arm, and hand.

Recognize the symptoms: An asymmetric Moro reflex in a newborn can indicate a problem with the nerves or muscles on one side of the body, often associated with brachial plexus injury.

Consider the causes: During birth, especially in difficult deliveries, the brachial plexus can be stretched or torn, leading to Erb's palsy.

Eliminate other options: Spinal cord malformation, congenital heart defect, and underdeveloped lungs are not typically associated with an asymmetric Moro reflex or Erb's palsy.

Conclude the most likely cause: Given the symptoms and context, the nurse would most likely suspect an injury to the brachial plexus during birth as the cause of the asymmetric Moro reflex in a newborn with Erb's palsy.
