The routine childhood immunization schedule is one of the most clinically important knowledge sets in pediatric nursing. The RPN administers vaccines at every well-child visit, advises parents on what to expect, identifies overdue or missed doses, and navigates catch-up scheduling for children who have fallen behind. For the REx-PN examination, schedule knowledge is tested both directly ('Which vaccines are due at a 4-month visit?') and indirectly ('A 14-month-old has not yet received MMR — is this a concern?').
