Chapter 20: The Adolescent: Growth, Development & Nursing Care

The Adolescent: Growth, Development & Nursing Care examines the complex biological, psychosocial, and cognitive changes occurring across early, middle, and late adolescence, grounded in major theoretical frameworks including Freud's genital stage of psychosexual development, Erikson's psychosocial crisis of identity versus role confusion, and Piaget's cognitive stage of formal operations which introduces abstract reasoning and logic. The summary details the physiological mechanisms of puberty, where the hypothalamus and pituitary gland stimulate the gonads to release androgens and estrogens, triggering the adolescent growth spurt, skeletal mass increases, and reproductive maturation. It explains the utility of Tanner's Sexual Maturity Ratings (SMRs) for assessing physical milestones such as breast development, genital maturation, and pubic hair distribution, alongside the concepts of asynchrony, epiphyseal closure, and menarche. Psychosocially, the text explores the shift from family dependence to peer group reliance, the formation of cliques, the importance of best friends, and the development of self-concept, often complicated by egocentrism and the imaginary audience phenomenon. Nutritional guidelines are outlined, emphasizing increased requirements for calories, calcium, iron, and zinc to support rapid growth, while addressing issues like fast-food consumption, vegetarianism, and the female athlete triad (eating disorders, amenorrhea, and osteoporosis). The chapter also addresses critical health promotion and safety topics, including risk-taking behaviors, motor vehicle safety, sports injuries, and the prevalence of substance abuse issues such as vaping, alcohol use, and inhalants, which can be screened using the PACE interview method. Furthermore, it covers sensitive topics such as sexual orientation, sex education, sexually transmitted infections, and adolescent pregnancy, while highlighting the nurse's role in maintaining confidentiality, providing nonjudgmental care, and preventing suicide, which remains a leading cause of death in this age group.
