NUR 2063 Pathophysiology Exam 1 2026 | 150+ Q&A | Fluid & Electrolytes, Acid–Base Balance, Immunity, Bone Disorders | Rasmussen University

This NUR 2063 Pathophysiology Exam #1 2026 study guide contains over 150 structured exam-style questions and answers covering foundational disease mechanisms and system-based pathophysiology. The document begins with core concepts such as etiology, idiopathic and iatrogenic conditions, differentiation, cell adaptation (atrophy, hypertrophy, hyperplasia, metaplasia, dysplasia), neoplasia, autosomal dominant and recessive inheritance, and cellular processes including mitosis, meiosis, diffusion, facilitated diffusion, and osmosis. The guide provides in-depth coverage of fluid compartments (ICF, ECF, intravascular, interstitial, transcellular), electrolyte distributions, and regulatory hormones such as ADH, aldosterone, and atrial natriuretic peptide. It thoroughly explains sodium, potassium, calcium, magnesium, chloride, and phosphorus imbalances, including clinical manifestations of hypernatremia, hyponatremia, hyperkalemia, hypokalemia, hypercalcemia, hypocalcemia, hypermagnesemia, hypomagnesemia, and phosphate disorders. Detailed acid–base balance interpretation is included, with respiratory and metabolic acidosis and alkalosis, ABG ranges, and associated compensatory mechanisms. Immunology content includes innate vs adaptive immunity, active and passive immunity, inflammatory response phases, pyrogens, interferons, T cells, B cells, and all four hypersensitivity reactions (Type I–IV) with clinical examples such as asthma, lupus, rheumatoid arthritis, contact dermatitis, and hemolytic disease of the newborn. The document also outlines HIV/AIDS CD4 classifications, host-versus-graft reactions, and graft-versus-host disease. Musculoskeletal and dermatologic sections cover osteoporosis, rickets, osteogenesis imperfecta types 1–4, compartment syndrome, fractures (transverse, oblique, spiral, comminuted, greenstick, compression), bone tumors (osteoma, osteosarcoma), kyphosis, and common skin findings such as café au lait spots, Mongolian spots, and nevi. The content aligns closely with major undergraduate nursing textbooks such as Pathophysiology: The Biologic Basis for Disease in Adults and Children by McCance & Huether, making it highly suitable for structured exam preparation. This document is especially relevant for: • Nursing students enrolled in NUR 2063 Pathophysiology • Rasmussen University ADN and BSN nursing students • Pre-licensure nursing students preparing for Exam 1 • Health science students reviewing foundational disease mechanisms • Students studying fluid balance, immune responses, and musculoskeletal pathology Keywords: pathophysiology exam 1, etiology, iatrogenic, idiopathic, cell adaptation, neoplasia, autosomal dominant, autosomal recessive, intracellular fluid, extracellular fluid, hypernatremia, hyponatremia, hyperkalemia, hypokalemia, hypercalcemia, hypocalcemia, acid base balance, respiratory acidosis, metabolic alkalosis, ADH, aldosterone, ANP, innate immunity, adaptive immunity, hypersensitivity reactions, HIV CD4 classification, osteoporosis, compartment syndrome, bone fractures, osteosarcoma
