NR 507 Week 7 Exam – 180 Questions on Diabetes Pathophysiology, GERD, Osteoporosis & Musculoskeletal Disorders – 2026

This document contains a comprehensive 180-question Week 7 exam review for NR 507, focusing on endocrine, gastrointestinal, musculoskeletal, and metabolic pathophysiology. The diabetes section provides detailed coverage of Type 1 autoimmune beta-cell destruction (T-helper activation, cytokine release, islet autoantibodies), Type 2 risk factors, classic symptoms (polyuria, polydipsia, polyphagia), DKA versus HHNKS mechanisms, diabetic retinopathy stages (nonproliferative, preproliferative, proliferative), nephropathy (RAAS activation, intraglomerular hypertension, decreased GFR), neuropathy, and macrovascular complications including hypertension, atherosclerosis, stroke, and peripheral vascular disease. Diabetes insipidus, ADH dysfunction, and nephrogenic DI are also reviewed. Gastrointestinal content includes GERD pathophysiology (LES dysfunction, delayed gastric emptying, hiatal hernia), pharmacologic management with proton pump inhibitors and H2 receptor antagonists, long-term complications such as strictures and dysphagia, gastric ulcer pathogenesis (H. pylori, parietal cell function, serum gastrin changes), and liver function test abnormalities. Eating disorders are comprehensively covered, including anorexia nervosa and bulimia nervosa diagnostic criteria, systemic complications (electrolyte imbalance, cardiac dysrhythmias, endocrine suppression), and associated metabolic disturbances. Musculoskeletal and metabolic bone disorders are thoroughly addressed, including osteoporosis screening with DXA and FRAX, fracture classifications (comminuted, spiral, compression, transchondral, greenstick, pathologic), hip fracture complications, osteomalacia pathophysiology related to vitamin D deficiency and PTH imbalance, laboratory abnormalities (calcium, phosphate, alkaline phosphatase), rhabdomyolysis (creatine kinase levels, myoglobinuria), epicondylitis, osteoarthritis pathogenesis, joint effusion mechanisms, and gout crystal deposition leading to inflammatory arthritis and tophi formation. The material aligns closely with Pathophysiology: The Biologic Basis for Disease in Adults and Children by McCance and Huether, a core textbook used in advanced pathophysiology courses. Concepts reflect system-based integration of endocrine regulation, inflammatory mechanisms, metabolic disturbances, and structural joint pathology emphasized in graduate nursing and nurse practitioner curricula. This document is particularly relevant for: Students enrolled in NR 507 Advanced Pathophysiology MSN and nurse practitioner students RN-to-MSN students studying endocrine and musculoskeletal disorders Nursing students preparing for system-based exams Healthcare students reviewing diabetes, GERD, osteoporosis, and inflammatory joint conditions It serves as a structured, exam-focused study guide designed to reinforce disease mechanisms, diagnostic criteria, laboratory interpretation, and complication recognition across multiple organ systems.
