NURS 5315 Advanced Pathophysiology Exam 1 2026/2027: 100+ Questions & Verified Answers – Cell Injury, Cancer, Fluids, Electrolytes, Acid-Base & Genetics – UTA

This NURS 5315 Advanced Pathophysiology UTA Exam 1 2026/2027 study resource is a comprehensive 26-page collection of 100+ real exam questions with verified answers covering major concepts in advanced pathophysiology. The material focuses on cellular injury and adaptation, reactive oxygen species (ROS), free radicals, action potentials, hypoxia and reperfusion injury, apoptosis and necrosis, cancer pathophysiology and TNM staging, fluid and electrolyte balance, edema, sodium and potassium disorders, calcium regulation, acid-base disturbances, DNA and RNA, chromosomal abnormalities, and genetic inheritance. The document explicitly identifies itself as NURS 5315 Advanced Pathophysiology UTA Exam 1, Latest 2026/2027 Update, with real questions and verified answers. The opening section examines reactive oxygen species, oxidative stress, and free-radical cellular injury. According to the study guide, ROS can contribute to lipid peroxidation, protein damage, DNA fragmentation, impaired protein synthesis, chromatin destruction, and mitochondrial injury. It associates oxidative damage with conditions including cardiovascular disease, hypertension, diabetes, ischemic heart disease, heart failure, Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis. The document identifies antioxidants such as vitamins E and C, cysteine, glutathione, albumin, ceruloplasmin, and transferrin as defenses against ROS. Students also review action potentials and membrane excitability, including depolarization, repolarization, and threshold potential. The resource connects these mechanisms with electrolyte abnormalities. Hypokalemia is described as producing a more hyperpolarized membrane and reduced excitability, whereas hyperkalemia produces relative hypopolarization and increased excitability. The guide similarly contrasts hypocalcemia, which increases sodium permeability and cellular excitability, with hypercalcemia, which decreases sodium permeability and reduces excitability. Clinical manifestations covered include weakness, paresthesia, tetany, hyperreflexia, seizures, dysrhythmias, paralysis, fatigue, and confusion. A major section focuses on cellular adaptation, requiring students to differentiate atrophy, hypertrophy, hyperplasia, dysplasia, and metaplasia. Atrophy is associated with decreased workload, use, blood supply, nutrition, hormonal stimulation, or nervous stimulation. Hypertrophy represents increased cell size and includes examples such as skeletal-muscle enlargement and left ventricular hypertrophy. Hyperplasia is an increase in cell number, while dysplasia involves abnormal changes in the size, shape, and organization of mature cells. Metaplasia is described as a reversible substitution of one mature cell type for another in response to chronic stress or irritation. The resource extends cellular pathology into carcinoma in situ, hypoxic injury, reperfusion injury, infarction, apoptosis, autophagy, and necrosis. Hypoxic injury is linked to decreased environmental oxygen, impaired hemoglobin function, reduced red-blood-cell production, and cardiopulmonary disease. Laboratory markers presented include CK, LDH, ALT, AST, and troponin. Reperfusion injury is explained through restoration of oxygen to ischemic tissue followed by generation of reactive intermediates, free radicals, membrane damage, and mitochondrial calcium overload. The study guide distinguishes apoptosis from necrosis. Apoptosis is presented as programmed cell death with implications for normal cellular regulation, neurodegenerative disease, ischemic injury, and elimination of virus-infected cells. Necrosis represents irreversible cell injury and is associated with manifestations such as fever, tachycardia, leukocytosis, pain, and release of intracellular enzymes. Students further differentiate coagulative necrosis, associated in the source with organs such as the kidney and heart, from liquefactive necrosis, which is associated with ischemic injury involving neurons and glial cells of the brain. Another substantial examination area is cancer pathophysiology. The resource compares normal cells with cancer cells, addresses differentiation, and reviews tumor terminology including carcinoma, sarcoma, adenocarcinoma-related terminology, blastoma, and benign “-oma” terminology as presented in the guide. Tumor markers discussed include alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), beta-human chorionic gonadotropin (β-hCG), and prostate-specific antigen (PSA). Students receive detailed preparation in cancer metastasis and TNM staging. The guide reviews common metastatic destinations for lung, colorectal, testicular, prostate, breast, head and neck cancers, sarcoma, and melanoma. The TNM system is broken into primary tumor extent (T), lymph-node involvement (N), and distant metastasis (M). A specific examination question asks students to interpret T3N2M0 as a large tumor with local lymph-node involvement but no evidence of distant metastasis according to the supplied answer. Additional oncology concepts include the BRCA gene, paraneoplastic syndromes, cancer cachexia, and cellular differentiation. BRCA is associated in the source with increased breast, ovarian, and prostate cancer risk. Paraneoplastic syndromes are described as effects triggered by cancer without being caused directly by the physical tumor mass, and the guide notes that they may represent an early manifestation of an otherwise unidentified malignancy. Cancer cachexia is presented as a wasting syndrome characterized by an imbalance between energy intake and energy utilization. The document then transitions into fluid distribution and Starling-related forces. Students review osmolality, osmosis, osmotic pressure, hydrostatic pressure, and oncotic pressure. Albumin is identified as the major plasma protein and an important contributor to oncotic pressure. Decreased albumin production or increased protein loss can reduce plasma oncotic pressure, causing fluid movement into the interstitial compartment and contributing to edema. Hormonal regulation of fluid volume is addressed through antidiuretic hormone (ADH/vasopressin), the renin-angiotensin-aldosterone system (RAAS), and natriuretic peptides ANP and BNP. The guide explains RAAS activation in response to reduced blood volume, followed by renin activity, angiotensin formation, vasoconstriction, aldosterone release, sodium and water retention, potassium excretion, and increased blood volume. ANP and BNP are presented as opposing volume-retaining mechanisms by promoting sodium and water excretion. Normal plasma osmolality is given as 280–295 mOsm/kg. Students also review hypertonic and hypotonic fluid effects. Hypertonicity increases extracellular solute concentration and osmolality, causing cells to shrink, whereas hypotonic conditions dilute the extracellular compartment and promote cellular swelling. Fluid-volume deficit is associated with dry mucous membranes, poor skin turgor, decreased urine output, sunken eyes, and fatigue, while fluid-volume excess is associated with edema, tight skin, periorbital puffiness, and rales or wet breath sounds. The edema pathophysiology section identifies four major mechanisms: increased hydrostatic pressure, decreased oncotic pressure, increased capillary permeability, and lymphatic obstruction. Examples include venous obstruction increasing hydrostatic pressure, liver disease and protein malnutrition reducing oncotic pressure, inflammation and burns increasing capillary permeability, and tumors or infection obstructing lymphatic drainage. These mechanisms explain why fluid accumulates in the interstitial compartment and produces swelling, puffiness, pitting, and impaired movement. Electrolyte disorders receive extensive attention. The document covers hypovolemic and hypervolemic hypernatremia, hyponatremia, hypokalemia, hyperkalemia, hypocalcemia, and hypercalcemia. Hyponatremia is organized by severity, progressing in the guide from manifestations such as nausea, lethargy, muscle cramps, and restlessness to agitation, disorientation, headache, seizures, coma, incontinence, and death in severe cases. Potassium regulation is connected to insulin, acid-base status, osmolality, exercise, renal function, medications, tissue injury, and adrenal function. Insulin shifts potassium intracellularly; alkalosis is associated with intracellular potassium movement and hypokalemia, whereas acidosis is associated with extracellular movement and hyperkalemia. Causes of hypokalemia listed include diuretics, diarrhea, laxative abuse, hyperglycemia, increased aldosterone, and alkalosis. Hyperkalemia causes include ESRD, ACE inhibitors, NSAIDs, tissue injury, adrenal insufficiency, hypoxia, insulin deficiency, acidosis, and digitalis overdose. The calcium and phosphorus material emphasizes their inverse relationship and regulation through parathyroid hormone, vitamin D, and calcitonin. Hypocalcemia is associated with increased cellular excitability, tetany, hyperreflexia, paresthesia, seizures, and dysrhythmias. Hypercalcemia reduces excitability and is associated in the source with polyuria, renal stones, nausea, vomiting, constipation, weakness, fatigue, confusion, and potentially coma. A key Exam 1 area is acid-base pathophysiology. Students review metabolic acidosis, metabolic alkalosis, respiratory acidosis, and respiratory alkalosis, including their causes, manifestations, electrolyte effects, and compensatory mechanisms. Metabolic acidosis is associated with renal disease, bicarbonate loss, ketoacidosis, and lactic acidosis, with hyperventilation or Kussmaul respirations presented as compensation. Metabolic alkalosis is associated with bicarbonate excess, vomiting, gastric suctioning, and diuretic use. Respiratory acidosis is connected with hypoventilation and impaired ventilation, including respiratory depression, neuromuscular disorders, obstructive sleep apnea, asthma, ARDS, COPD, and pneumonia as listed in the source. Respiratory alkalosis is associated with hyperventilation, hypoxemia, pulmonary embolism, heart failure, high altitude, fever, sepsis, anemia, anxiety, hepatic failure, and salicylate overdose. Neurological manifestations reviewed include dizziness, confusion, paresthesias, tremors, convulsions, seizures, and coma. The final section provides an important review of molecular genetics and inheritance. Students review the four DNA nitrogenous bases—adenine, thymine, cytosine, and guanine—and the base-pairing relationships A–T and G–C. DNA replication, RNA, transcription, translation, mRNA, tRNA, ribosomes, protein formation, gametes, somatic cells, meiosis, mitosis, haploid cells, and diploid cells are also covered. Chromosomal abnormalities include polyploidy, aneuploidy, autosomal aneuploidy, sex-chromosome aneuploidy, deletion, duplication, inversion, and translocation. Examples include trisomy 21/Down syndrome, Turner syndrome, Klinefelter syndrome, and Cri-du-chat syndrome. The genetics review additionally identifies Huntington disease with a dominant disease allele, cystic fibrosis as autosomal recessive, phenylketonuria as homozygous recessive, and radiation as an example of a chromosome-damaging clastogen. Overall, this NURS 5315 Advanced Pathophysiology Exam 1 resource is particularly relevant for students seeking concentrated preparation in the cellular and molecular mechanisms underlying disease. Its question-and-answer format spans cellular adaptation and injury, oncology, fluid and electrolyte regulation, acid-base physiology, and genetics, making it a broad review for the first NURS 5315 examination.
