Answer to Question 1

ANS: B
The average age of menarche is 12 years and 4 months in North American girls, with a normal range of 10.5 to 15 years.

Answer to Question 2

ANS: D
Concerns about pubertal delay should be considered for boys who exhibit no enlargement of the testes or scrotal changes by 13.5 to 14 years of age. Ages younger than 13.5 years are too young for initial concern.
