PORTAGE LEARNING NURS 231 FINAL EXAM QUESTIONS AND CORRECT ANSWERS

Pass the PORTAGE LEARNING NURS 231 Final Exam with confidence using this comprehensive collection of correct, verified questions and answers. Designed for nursing students mastering foundational pathophysiology, this resource covers high-yield topics frequently tested on the NURS 231 cumulative final, including: Cellular Adaptation & Injury: Hypertrophy (normal vs pathological), gangrenous necrosis (dry vs wet comparison), mitochondrial function (cellular respiration, apoptosis), cell membrane properties, and true/false distinctions between cell proliferation and differentiation. Cancer & Oncology Basics: Chemotherapy as systemic treatment, cancer anorexia-cachexia syndrome, metastatic cell survival characteristics, stem cell properties (potency and self-renewal), and progenitor/parent cells. Immunology & Autoimmune Disorders: Challenges in diagnosing autoimmune disorders (overlapping presentations, imprecise lab markers), T cell negative selection, viral infection lab values (lymphocytes), anaphylaxis management (symptoms, epinephrine dosing, EpiPen + allergy ID), and chronic transplant rejection (humoral immunity). Hematologic Disorders: Sickle cell anemia (peripheral smear findings, leg ulcers, pain crises), vitamin B12 deficiency (MCV increased, NOT decreased, peripheral neuropathy, intrinsic factor binding), and anemia differentiation. Cardiovascular & Metabolic Risk Factors: Secondary hyperlipidemia risk factors (obesity, diabetes, high cholesterol diet – excluding autosomal dominant LDL receptor disorder), coronary heart disease risk factors (HDL 60 is protective, NOT a risk factor), and hyperglycemia vs Addison's disease signs. Pulmonary Pathophysiology: Diffusion (gas exchange between alveoli and pulmonary capillaries), atelectasis causes (pleural effusion, tumor, mucous plug – thrombus does NOT cause atelectasis), and acute asthma exacerbation pathophysiology (airway inflammation, epithelial injury, bronchial hyperresponsiveness, albuterol resistance). Neurologic Disorders: Ischemic stroke (symptoms, CT/MRI confirmation, catheter-based clot intervention), Alzheimer's disease staging (early stage independence with ADLs), oligodendrocytes (CNS myelination – NOT PNS), and proprioception (tendons/ligaments protecting joints on uneven terrain). Gastrointestinal & Hepatic Disorders: Gallstone risk factors (obesity, age 40+, pregnancy – NOT male gender), peptic ulcer disease risk factors (H. pylori, NSAIDs, family history, alcohol – stress is NOT a risk factor), peristaltic movements in the small intestine, and contraindications for anti-diarrheal medications. Renal & Acid-Base Balance: Stage 2 kidney disease (GFR 60-89 mL/min/1.73m²), renal autoregulation (afferent/efferent arteriole constriction maintaining constant GFR), and metabolic alkalosis with dehydration (pH 8.2, HCO3 33, normal PCO2 – no compensation, treatment with normal saline). Endocrine Disorders: Hypothyroidism (low T4, elevated TSH, fatigue, weight gain, cold intolerance – treatment with thyroxine), diabetic ketoacidosis symptoms (polydipsia, dehydration, fruity breath – bradycardia is NOT present), and osteoarthritis (morning stiffness resolving in 30 minutes). Musculoskeletal & Gout Management: Phase 2 gout (NSAIDs for inflammation/pain, weight loss, reduced alcohol), phase 3 gout inter-critical phase (allopurinol to reduce uric acid, purine avoidance), and bone circulation (Haversian/Volkmann canals, nutrient artery anastomosis, diffusion through endosteum/canaliculi). Each answer provides clinical distinctions, true/false clarifications, and treatment protocols essential for exam success. Perfect for NURS 231 final exam cram sessions, pathophysiology review, and nursing fundamentals mastery.
