Which of the following actions should the nurse perform to elicit this reflex?
Explanation
This will elicit the Moro reflex, which is a normal, involuntary reaction that newborns and infants have when they’re startled.When something triggers the Moro reflex, a baby will extend their arms — moving them outward at the shoulder and then straightening them — and throw their head back.A few seconds later, the arms will naturally come back down and in towards the body.
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?
Explanation
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.
