NSG 5003 Exam Questions & Answers 2026/2027 | 50 Questions | Pathophysiology, Immunology, Cancer, Diabetes, Neurology & Hematology

This NSG /2027 Exam Questions and Answers document contains 50 multiple-choice questions with answers across 48 pages, providing an extensive exam-focused review of advanced pathophysiology, cellular injury, fluid and electrolyte balance, acid-base physiology, immunology, hypersensitivity, cancer, neurological disorders, endocrine disease, diabetes, reproductive pathology, hematology, cardiovascular physiology, pulmonary physiology, and gastrointestinal disease. The questions emphasize application of underlying disease mechanisms rather than simple terminology, making the resource particularly useful for students preparing for NSG 5003 examinations and advanced nursing pathophysiology assessments. The opening questions concentrate on cellular biology and mechanisms of cell injury, including peroxisomes, hydrogen peroxide production, mitochondrial dysfunction, ATP depletion, plasma-membrane damage, apoptosis, hypoxic cell injury, sodium and water movement, and DNA abnormalities associated with ionizing radiation. The document then moves into fluid, electrolyte, and acid-base physiology, examining dehydration, hydrostatic and oncotic forces, edema formation, capillary hydrostatic pressure, natriuretic peptides, hypernatremia, potassium and resting membrane potential, hyperkalemia, and the bicarbonate-to-carbonic-acid relationship involved in physiological pH regulation. A substantial section addresses immunology, inflammation, hypersensitivity, and vaccination. Students review major histocompatibility complex (MHC) and CD1 molecules, B-cell receptor signaling, clonal diversity, primary lymphoid organs, immunoglobulins, vaccine-mediated immunity, type II hypersensitivity reactions, antigen-antibody interactions, neutrophil-mediated tissue injury, fever mechanisms, and viral vaccines. The questions integrate molecular and cellular immunology with clinically relevant immune responses and disease mechanisms. The cancer section examines oncogenes, hypomethylation, tumor-suppressor genes, the two-hit hypothesis, carcinoma in situ, chemotherapy-associated health risks, and pediatric cancer outcomes. Questions require students to connect genetic and epigenetic alterations with carcinogenesis and tumor progression while also recognizing clinical implications of cancer and its treatment. Neurological and cardiovascular pathophysiology are represented through questions on the medulla oblongata, spinal cord injury, autonomic hyperreflexia/dysreflexia, atheromatous plaque formation, and multiple sclerosis. The document examines why upper cervical spinal cord edema can threaten respiration and reviews the characteristic hypertensive autonomic response associated with spinal cord lesions above T6. Cardiovascular material additionally considers angiotensin II and increased cardiac workload following myocardial infarction. The endocrine portion provides targeted examination of Graves disease, type 1 and type 2 diabetes mellitus, diabetic ketoacidosis, hypoglycemia, the Somogyi effect, insulin resistance, and metabolic disturbances associated with diabetes. Questions integrate clinical manifestations and laboratory findings with underlying pathophysiological mechanisms, helping students practice linking endocrine dysfunction to observable patient presentations. The later questions broaden the review to reproductive and hematological pathophysiology, including endocervical epithelial tissue, cervical dysplasia and carcinoma in situ, vitamin B12 assessment with the Schilling test, aplastic anemia, autoimmune hemolytic anemia, Rh incompatibility, hemolytic disease of the newborn, and neonatal hyperbilirubinemia. The final material additionally addresses pulmonary capillary physiology and celiac disease, including the relationship between fat malabsorption, vitamin K deficiency, bruising, and bleeding.
