During a newborn exam, the nurse identifies crepitus. Which further assessment should be performed?

Identifying crepitus during a newborn exam can indicate a possible fracture of the clavicle or other bony structures. Observing for an asymmetrical Moro reflex is a crucial step in further assessment because this reflex can help determine if there is an injury to the brachial plexus or the shoulder area that might have resulted from a fracture.

The Moro reflex, also known as the startle reflex, is a normal reflex in newborns where they spread their arms and then retract them when they feel a sudden loss of support. An asymmetrical response in this reflex can suggest that there is a neurological issue or injury to one side of the body, which could correlate with the presence of crepitus.

In this context, gathering information about the Moro reflex can provide insight into the severity of any potential injury, allowing for appropriate interventions and management if necessary. This focus on neuromuscular function is essential in a comprehensive approach to assessing the newborn following the identification of crepitus.
