Summary ( 15 Questions)
A nurse is performing a routine check-up on a 2-month-old infant.
The nurse gently drops the infant from one hand to the other and observes that the infant’s arms and legs symmetrically extend, then abduct while fingers spread to form a C-shape.
The nurse identifies this as:
The Moro reflex, or startle reflex, is a newborn reflex that occurs when a baby is startled by a loud noise or sudden movement. The baby responds by extending and abducting the arms and legs, spreading the fingers to form a C-shape, and then bringing the arms and legs back to the chest. This reflex is present at birth and disappears by 3 to 6 months of age.
it is a reflex that helps a baby find a nipple to feed. It is triggered by stroking or touching the corner of the baby’s mouth, which causes the baby to turn their head and open their mouth in that direction. This reflex develops around 28 to 30 weeks of gestation and lasts until about 4 months of age.
it is a reflex that causes the baby to laterally flex toward the stimulated side when the skin on one side of the back is stroked. It is elicited by holding the baby in ventral suspension (face down) and stroking along one side of the spine. This reflex is present at birth and disappears by 4 to 6 months of age.
it is a reflex that causes the baby to extend the legs and attempt to support their weight when the feet touch a flat surface. It is elicited by supporting the baby in vertical suspension with the feet touching a mat or table. This reflex develops around 3 to 4 months of age and disappears by 6 to 9 months of age.
