Which reflex is expected to disappear by 4 months of age?

  • A. Rooting reflex
  • B. Moro reflex
  • C. Babinski reflex
  • D. Palmar grasp
Correct Answer: B

Rationale: The Moro reflex, also known as the startle reflex, typically disappears by 4 months as the infant's nervous system matures. This reflex is important for assessing the development of the nervous system in newborns. The Rooting reflex (Choice A) is related to turning the head in response to cheek stimulation; the Babinski reflex (Choice C) involves the fanning of toes in response to foot stimulation; and the Palmar grasp (Choice D) is the curling of the fingers around an object placed in the infant's hand. These reflexes have different timelines for disappearance and are not typically expected to be gone by 4 months of age.
