Hepatitis B is given at birth and 1–2 months .
3. A newborn's examination reveals a positive Ortolani maneuver. What is the most
appropriate diagnostic study?

heads not yet ossified. X-ray is used after 4–6 months .
4. Which is the best position for an infant to sleep?

7. During a 2-month-old well visit, the red reflex in one eye appears paler than the other.
What is the most appropriate action?
Answer: Refer the infant to a pediatric ophthalmologist immediately
