In a physical exam, which of these reflexes should be assessed in a newborn?

In a physical exam of a newborn, assessing all of these reflexes is integral to evaluating the baby's neurological development and overall health.

The grasp reflex is observed when an object placed in a newborn's palm results in a tight grasp. This reflex indicates functional muscle tone and neurological activity.

The sucking reflex occurs when something touches the roof of a baby's mouth, prompting them to suck. This reflex is vital for feeding and demonstrates the infant's ability to coordinate sucking, swallowing, and breathing.

The Babinski reflex involves the response of the newborn’s toes when the sole of the foot is stroked; the toes fan outward. This reflex is considered a normal finding in infants and is an important indicator of the integrity of the corticospinal pathways.

Assessment of all these reflexes provides insights into the newborn’s neurological status and development, which is why it is essential to include each reflex in the examination.
