Chapter 51: The Child With an Endocrine or Metabolic Alteration

Related genetic metabolic conditions such as galactosemia and Tay-Sachs disease are explored alongside their pathophysiological mechanisms and nursing management approaches. The chapter then addresses adrenal disorders, particularly congenital adrenal hyperplasia, which involves defective steroid synthesis resulting in excessive androgen production and potentially life-threatening acute adrenal crises with severe electrolyte disturbances. Thyroid dysfunction is examined through multiple conditions: congenital and acquired hypothyroidism, which can impair neurodevelopmental outcomes if not promptly treated, and Graves disease, representing an autoimmune form of hyperthyroidism with distinct clinical manifestations. Posterior pituitary disorders are contrasted, comparing diabetes insipidus with its associated dehydration and hypernatremia against the syndrome of inappropriate antidiuretic hormone secretion, characterized by fluid retention and hyponatremia. Growth and developmental concerns, including growth hormone deficiency and precocious puberty, are discussed with attention to both physiological consequences and psychosocial impacts on children and families. The chapter emphasizes diabetes mellitus as a prevalent chronic condition, differentiating the beta cell destruction mechanisms of Type 1 diabetes from the insulin resistance patterns of Type 2 diabetes. Clinical nursing priorities focus on insulin management strategies, medical nutrition therapy, monitoring for acute metabolic emergencies such as hypoglycemia and diabetic ketoacidosis, and supporting families through long-term disease management and lifestyle adaptation.
