The key details in the question stem are:- Male newborn delivered at 33 weeks gestation - Birth weight 1800g 4.0 lb- Apgar scores 7 and 8 - Mother has iron deficiency anemia, 10 year history of smoking, and previous placenta previa- Mother has received all appropriate immunizations The choices list different vaccine options and recommended ages. To answer correctly, I need to consider the CDCAAP guidelines for immunizing premature infants based on chronological age vs corrected age. Premature infants are at higher risk of certain infections, so some vaccine schedules may be accelerated. However, immune response may be blunted in premature infants, so some vaccines need to be delayed. Ill need to weigh these factors for each answer option.E: Give first dose of diphtheria and tetanus toxoids, acellular pertussis DTaP vaccine at 2 months of chronological age
