A nurse in a clinic is assessing a 9-month-old infant. Which of the following findings requires further intervention?

The correct answer is B: Positive Moro reflex. At 9 months, the Moro reflex should have disappeared. Its presence could indicate a delay in neurological development or a potential neurological issue. A negative Doll's eye reflex, negative Crawl reflex, and positive Babinski reflex are all normal findings in infants at this age. The Doll's eye reflex is typically present until around 6 months, the Crawl reflex disappears around 3-6 months, and the Babinski reflex is normal in infants until around 2 years of age. Therefore, the positive Moro reflex is the concerning finding that requires further intervention to assess the infant's neurological status.
