NR 507 Final Exam – 220 Questions on Pathophysiology, Cardiovascular Disorders, Endocrine Imbalances & Genetic Conditions – 2026

This document contains a comprehensive 220-question final exam review for NR 507, focusing on advanced pathophysiology across multiple body systems. The material covers neurological disorders (dermatomes, ischemic penumbra, cerebral infarction, agnosia, meningitis, subarachnoid hemorrhage), cardiovascular pathophysiology (hypertension mechanisms, SNS and RAAS activation, atherosclerosis, unstable plaque formation, heart failure differentiation, infective endocarditis, DVT and Virchow’s triad), pulmonary disorders (pneumothorax types, ARDS, Cheyne-Stokes respirations, alpha-1 antitrypsin deficiency), and hematologic conditions (iron deficiency anemia, aplastic anemia, sickle cell disease, autoimmune hemolytic anemia, polycythemia, anemia of chronic renal failure). Endocrine and metabolic disorders are extensively reviewed, including Cushing’s disease, thyroid storm, primary hypothyroidism, hypoparathyroidism, insulin resistance in hypertension, glucose regulation in shock, and electrolyte imbalances such as hypernatremia. Reproductive and hormonal disorders such as PCOS, abnormal uterine bleeding (PALM-COEIN), PMDD, uterine prolapse, prostate cancer pathophysiology, HPV-related cervical cancer, and ovulatory cycle phases are also detailed. The document further includes immunology and infectious disease concepts such as innate versus adaptive immunity, MHC Class I antigens, antibiotic resistance mechanisms, vaccine development principles, desensitization therapy, acute phase reactants (CRP), and normal flora functions. Genetic and chromosomal disorders are thoroughly addressed, including Down syndrome (Trisomy 21), Klinefelter syndrome (XXY), neurofibromatosis, Duchenne muscular dystrophy, multifactorial traits, transcription and translation processes, and mutation types (base pair substitution, frameshift mutations). Fluid and electrolyte balance, shock physiology, oncotic pressure, ADH regulation, and body fluid compartments are also covered in detail. The content aligns closely with Pathophysiology: The Biologic Basis for Disease in Adults and Children by McCance and Huether, a primary textbook used in advanced pathophysiology courses. Topics reflect system-based disease mechanisms, cellular injury processes, genetic alterations, inflammatory pathways, and compensatory physiological responses commonly emphasized in graduate-level nursing and nurse practitioner curricula. This document is particularly relevant for: Students enrolled in NR 507 MSN and nurse practitioner students studying advanced pathophysiology RN-to-BSN students completing upper-level pathophysiology courses Nursing students preparing for cumulative system-based final exams Healthcare students reviewing cardiovascular, endocrine, and genetic disease mechanisms It serves as a structured, exam-focused study guide designed to reinforce deep understanding of disease mechanisms, clinical manifestations, laboratory interpretation, and system interactions essential for advanced nursing practice.
