Chapter 59: Concepts of Care for Patients With Diabetes Mellitus

Diabetes mellitus represents a systemic metabolic disorder that disrupts glucose homeostasis and cascades through multiple physiological systems, necessitating comprehensive nursing management centered on glycemic control. This chapter synthesizes diabetes care across the continuum from prevention through chronic disease management, addressing how impaired nutrient metabolism fundamentally compromises fluid and electrolyte balance, acid-base equilibrium, tissue perfection, sensory function, immune response, and nutritional status. The chapter emphasizes recognizing risk factors including gestational diabetes history and metabolic syndrome as critical assessment components for early intervention. Acute complications demand rapid clinical recognition and intervention: diabetic ketoacidosis represents a life-threatening state of severe hyperglycemia with metabolic acidosis requiring immediate fluid resuscitation and insulin therapy, while hyperglycemic-hyperosmolar state presents with extreme hyperglycemia and hyperosmolality where cerebral edema signals constitute medical emergencies warranting urgent reporting. Hypoglycemic episodes, conversely, require swift glucose administration to prevent neurological damage. The chapter prioritizes patient self-management education as fundamental to long-term outcomes, recognizing that literacy challenges and vision impairment common among diabetic populations necessitate individualized teaching strategies and accessible learning materials. Medication adherence assumes central importance, with detailed attention to insulin administration, oral antidiabetic agents, and injectable medications such as pramlintide, which carries specific contraindications regarding mixing with insulin preparations. Chronic microvascular and macrovascular complications including diabetic nephropathy with microalbuminuria progression, retinopathy, and neuropathy represent predictable sequelae requiring aggressive prevention strategies. Preventive foot care education emerges as a cornerstone intervention given the high incidence of tissue breakdown, infection, and amputation in diabetic populations. Successful diabetes management mandates interprofessional collaboration integrating physician, nurse, dietitian, and mental health expertise to sustain optimal glycemic control and prevent disease progression.
