A client asks a nurse why their baby exhibits the Moro reflex when they hear a loud noise.
Which of the following responses should the nurse give?
The Moro reflex is a startle reflex that occurs when a baby hears a loud noise or feels a sudden movement. It causes the baby to throw back his or her head, extend out his or her arms and legs, cry, then pull the arms and legs back in. It is a normal reflex that shows the baby’s nervous system is working well and it usually disappears by 4 months of age.
the Moro reflex is not a protective mechanism that helps the baby cling to their mother. It is an involuntary response that does not involve grasping.
the Moro reflex is not a sign of distress and does not indicate that the baby needs comfort. It is a normal reflex that does not mean the baby is unhappy or in pain.
the Moro reflex is not a primitive reflex that has no known function in humans. It is a normal reflex that may have had an evolutionary role in helping infants alert their caregivers or prepare for a fall.
