NUR 280 Glucose Regulation Exam 2 Study Guide | 80+ Practice Questions & Verified Answers | Diabetes Mellitus, Insulin, Glucose Metabolism, Diabetic Complications & Nursing Management | 2026

Prepare for NUR 280 Glucose Regulation Exam 2 with this comprehensive study guide featuring 80+ expertly organized practice questions and verified answers covering the essential concepts of glucose regulation, diabetes mellitus, endocrine physiology, and nursing management. This resource provides an in-depth review of carbohydrate metabolism, insulin production and function, glucose transport, glycogenesis, glycogenolysis, gluconeogenesis, diabetes mellitus classifications, diagnostic testing, blood glucose interpretation, hemoglobin A1C, diabetic ketoacidosis (DKA), acute and chronic diabetic complications, glycemic control, patient education, nutrition, exercise, foot care, and self-monitoring of blood glucose. The material is presented in a structured question-and-answer format that promotes active recall, strengthens clinical reasoning, and prepares nursing students for quizzes, unit examinations, comprehensive exams, and NCLEX-style assessments. This study guide systematically explains the principles of glucose metabolism and endocrine regulation, including insulin secretion by the beta cells of the Islets of Langerhans, glucose uptake into body cells, glycogen formation and storage, glycogen breakdown, gluconeogenesis, insulin resistance, and the physiological mechanisms responsible for maintaining blood glucose homeostasis. Students will review the pathophysiology of Type 1 diabetes mellitus, Type 2 diabetes mellitus, gestational diabetes mellitus, and secondary causes of diabetes, while also examining major risk factors such as obesity, sedentary lifestyle, autoimmune disorders, pancreatic disease, medication toxicity, pregnancy-related hormonal changes, and genetic predisposition. The guide also reviews the interpretation of fasting plasma glucose, oral glucose tolerance testing (OGTT), random plasma glucose, glycated hemoglobin (HbA1C), glucosuria, ketonuria, hyperglycemia, and hypoglycemia, reinforcing diagnostic criteria commonly tested in undergraduate nursing courses. The resource further provides extensive coverage of acute and chronic diabetic complications and evidence-based nursing management, including polydipsia, polyuria, polyphagia, diabetic ketoacidosis (DKA), electrolyte disturbances, accelerated atherosclerosis, coronary artery disease, peripheral arterial disease, stroke, nephropathy, renal failure, retinopathy, peripheral neuropathy, lower-extremity amputation, immunosuppression, dermatologic complications, and psychological disturbances. Students will also master the differences between the Dawn Phenomenon and the Somogyi Effect, along with recommended interventions involving insulin adjustment, meal timing, and exercise modification. In addition, the guide emphasizes comprehensive diabetes self-management strategies, including glycemic index nutrition, blood glucose monitoring, cardiovascular risk reduction, smoking cessation, blood pressure and lipid management, proper foot care, podiatry follow-up, and patient education. Organized into concise, exam-focused questions and answers, this study guide serves as an excellent revision resource for mastering the glucose regulation concepts most frequently assessed in NUR 280 Exam 2 and NCLEX-style examinations. The content aligns with the foundational principles presented in leading pathophysiology and medical-surgical nursing textbooks widely adopted in undergraduate nursing, BSN, and ADN programs.
