Explanation
Choice A is correct. The Moro reflex is present at birth, starts to diminish as early as three months, and is absent by 6 months. Persistent response after 6 months could indicate a neurologic abnormality.
→ To elicit the Moro reflex, the nurse should hold the newborn semi-sitting and allow the head and neck to fall backward (supported) at least 30 degrees. A positive reflex is when the newborn extends and abducts arms, followed by flexion and adduction.
Choice B is incorrect. This reflex should not diminish within 1-3 months.
Choice C is incorrect. This reflex should not diminish within 7-9 months.
Choice D is incorrect. This reflex should not diminish within 10-12 months.
