Chapter 18: The Adolescent: Growth, Health & Nursing Care

The Adolescent: Growth, Health & Nursing Care outlines the crucial physiological changes governed by the hypothalamus-pituitary-gonad axis, where hormonal signals stimulate the gonads to release androgens and estrogens, triggering the development of reproductive organs and secondary sex traits. The summary details the rapid physical growth known as the growth spurt, the phenomenon of asynchrony which leads to a gangling appearance, and the eventual epiphyseal closure that halts height progression. Key developmental theories are integrated, including Sigmund Freud's genital stage of psychosexual development, Erikson’s psychosocial crisis of identity versus role confusion, and Jean Piaget’s cognitive stage of formal operations, which enables abstract reasoning and logic. Significant attention is given to the Tanner Stages (Sexual Maturity Ratings) for assessing breast and genital development in both sexes. The narrative explores the complex psychosocial adjustments adolescents face, such as the intense need for privacy, the formation of cliques and peer groups to facilitate separation from the family, and the development of sexual orientation and gender identity. Health promotion strategies are emphasized, covering nutritional requirements like increased calcium, iron, and zinc needs, the risks of fad diets or vegetarian deficiencies, and the management of the female athlete triad (eating disorders, amenorrhea, and osteoporosis). The chapter also addresses critical safety and behavioral concerns, including motor vehicle safety, depression, suicide risks (with specific statistics regarding Indigenous youth in Canada), and substance use involving vaping and inhalants. Assessment tools like the HEADSSS psychosocial history and the CRAFFT screening tool for substance abuse are introduced as essential components of pediatric nursing care to support the adolescent's journey toward independence and self-actualization.
