Growth, Development, And Preventive Care Practice Test

A 9-month-old boy is brought to the clinic for a well-child visit. His mother is concerned because he is not yet crawling. His birth history was unremarkable, and he has been meeting other milestones appropriately. On examination, he can sit unsupported, babbles, and has a pincer grasp. When placed on his stomach, he pushes up on his hands and knees and rocks back and forth. His growth parameters are at the 50th percentile for age.

A healthy 4-month-old infant is brought for a well-child visit. He was born full-term and has had no medical problems. He is exclusively breastfed. His immunizations are up-to-date. The mother asks which vaccines her child will receive today.
