What do doctors check during a physical exam of a 12-year-old boy?

Head-to-toe: First: vital signs. Heart rate, blood pressure, weight, height. We will also check their vision. Then a head to toe exam just like in previous exams. ENT, heart, lungs and abdomen. We look for signs for the onset of puberty including pubic hair, and testicular size. We talk to the child about maturation, general safety, activity specific safety, avoiding high risk behaviors, school and friends.
