A nurse is assessing the growth and development of a 16-year-old adolescent. Which of the following behaviors or physical changes would the nurse expect to observe in a typical adolescent at this stage? (Select all that apply)

A. Full adult height and the cessation of body changes is incorrect because while many adolescents are nearing adult height by age 16, some continue to grow, particularly males. Body changes may still be ongoing, so complete cessation of growth is not typical. B. A decrease in growth rate and an increase in body fat distribution is correct because by mid-adolescence, the rapid growth of puberty slows, and changes in body composition occur. Females typically experience an increase in body fat, while males may see a decrease in fat with increased muscle mass. C. Heightened interest in forming intimate relationships outside the family is correct because adolescents at this stage begin exploring romantic and sexual relationships and may form emotional attachments with peers or romantic partners. D. Increased independence and desire for privacy, with a focus on peer relationships is correct because autonomy and identity formation are key developmental tasks of adolescence. Adolescents seek privacy, rely more on peers, and may challenge parental authority as part of normal psychosocial development. E. Development of secondary sexual characteristics such as facial hair in males and breast development in females is correct because most adolescents have completed or are in the later stages of puberty by age 16, with secondary sexual characteristics well established.
