What's Inside – Complete NURS 6030 Exam 1 Domain Coverage: Category Key Concepts & Questions Covered Cellular Biology Eukaryotes vs prokaryotes; eight chief cellular functions (movement, conductivity, metabolic absorption, secretion, excretion, respiration, reproduction, communication); nucleus (cell division, genetic control); cytoplasm; endoplasmic reticulum (protein synthesis/folding); Golgi complex (processing/packaging); lysosomes (digestive enzymes, 4 degradation pathways); peroxisomes (oxidative enzymes); mitochondria (cellular respiration, ATP production – electron transport chain); cytosol; cytoskeleton (microtubules, microfilaments); plasma membrane (lipid bilayer, proteins functions) Proteins & Proteostasis Proteins as major workhorses; proteostasis (balance of synthesis, folding, degradation); cellular receptors (recognize ligands); signal transduction pathways (cAMP, Ca++); G proteins; phospholipase C Cell-to-Cell Communication Cell adhesion molecules (CAMs – integrins, selectins, immunoglobulin superfamily); three main cell junctions (desmosomes, tight junctions, gap junctions); primary signaling modes (contact-dependent, paracrine, hormonal, neurohormonal, neurotransmitter) Membrane Transport Passive transport (diffusion, osmosis, hydrostatic pressure) – no energy required; active transport (requires ATP); simple diffusion across lipid bilayer (O2, CO2); osmosis (water movement toward higher solute concentration); aquaporins (water channels); mediated transport (symport, antiport, uniport); endocytosis (pinocytosis, phagocytosis, receptor-mediated); exosomes; exocytosis Membrane Potential Resting membrane potential (inside negatively charged); action potential (depolarization – Na+ channels open; repolarization – K+ channels open); absolute refractory period; relative refractory period Tissues & Cellular Adaptation Four basic tissue types (epithelial, connective, muscle, neural); stem cells; atrophy (decrease in cell size – physiologic vs pathologic); hypertrophy (increase in cell size); hyperplasia (increase in cell number – compensatory, hormonal, pathologic); metaplasia (replacement of one mature cell type by another); dysplasia (abnormal changes in size/shape/organization) Cell Injury & Death Hypoxia (lack of oxygen – most common cause); ischemia (insufficient blood supply); anoxia (absence of oxygen); causes of hypoxia (blocked vessels, respiratory disease, anemia, edema); free radicals and ROS (oxidative stress); intracellular calcium accumulation (activates proteases, phospholipases, endonucleases); reperfusion injury; necrosis (rapid loss of plasma membrane); apoptosis (programmed cell death); gangrene; intracellular accumulations; dystrophic vs metastatic calcification Fluid & Electrolyte Balance Total body water (60% body weight – 40% ICF, 20% ECF); water intake/output ( cc/day); infants have higher TBW (70-80% – less body fat); older adults have decreased TBW; sodium (primary ECF cation, responsible for osmotic balance); potassium (primary ICF cation, regulates resting membrane potential); aldosterone (regulates sodium reabsorption); ADH (antidiuretic hormone – water reabsorption); RAA system (renin-angiotensin-aldosterone – regulates BP and volume); atrial natriuretic hormone (promotes urinary sodium excretion) Edema Four mechanisms: increased capillary hydrostatic pressure, decreased capillary oncotic pressure, increased capillary permeability, lymphatic obstruction; Starling forces (capillary hydrostatic pressure, capillary oncotic pressure, interstitial hydrostatic pressure, interstitial oncotic pressure); albumin (primary plasma protein for oncotic pressure) Osmolality & Tonicity Isotonic (equal to normal serum osmolality – cell stays same); Hypotonic (less than normal – cell swells); Hypertonic (greater than normal – cell shrinks); water moves toward higher osmolality Sodium Disorders Hypernatremia (high sodium – cells shrink); Hyponatremia (low sodium – water moves into cells, swelling); Euvolemic hyponatremia; Hypervolemic hypernatremia Potassium Disorders Hypokalemia (low potassium – palpitations, fatigue, muscle spasms, cardiac dysrhythmias); Hyperkalemia (high potassium – difficulty breathing, muscle paralysis, palpitations, weakness, cardiac arrest); Acidosis causes hyperkalemia (H+ moves into cells, K+ moves out) Calcium Disorders Hypocalcemia (low calcium – muscle tetany, neurons more excitable); calcium stabilizes sodium channels; hypercalcemia Acid-Base Balance pH normal range 7.35-7.45; PaCO2 normal 35-45; HCO3 normal 22-26; Buffers (bicarbonate, protein, phosphate); Renal and respiratory compensation; ROME acronym (Respiratory Opposite, Metabolic Equal) Acid-Base Disorders Metabolic acidosis (low pH, low HCO3 – causes: DKA, renal failure, diarrhea, shock; symptoms: headache, decreased BP, hyperkalemia, warm flushed skin, nausea); Metabolic alkalosis (high pH, high HCO3 – causes: vomiting, NG suction, diuretics, excessive NaHCO3; symptoms: restlessness, tachycardia, hypoventilation, confusion, hypokalemia); Respiratory acidosis (low pH, high PaCO2 – causes: hypoventilation, COPD, pneumonia, overdose; symptoms: hypoxia, rapid shallow breaths, headache, hyperkalemia, drowsiness); Respiratory alkalosis (high pH, low PaCO2 – causes: hyperventilation, anxiety, mechanical ventilation; symptoms: tachycardia, hypokalemia, numbness/tingling, seizures) ABG Interpretation Practice Multiple ABG problems with answers (uncompensated metabolic alkalosis, partially compensated metabolic acidosis, normal, partially compensated respiratory acidosis, uncompensated respiratory alkalosis, partially compensated metabolic alkalosis) Genetics Fundamentals DNA structure (double helix, nucleotides: A-T, G-C); genes (basic units of inheritance on chromosomes); mutation (inherited alteration of genetic material); transcription (DNA → mRNA); translation (mRNA → protein); introns vs exons; microRNAs (miRNAs); transcription factors Cell Division Somatic cells (diploid – 46 chromosomes); gametes (haploid – 23 chromosomes); mitosis (somatic cell division – produces identical diploid cells); meiosis (gamete formation – produces haploid cells, crossing over); karyotype (ordered display of chromosomes by length); autosomes (first 22 pairs); sex chromosomes (23rd pair – XX female, XY male) Chromosomal Disorders Polyploidy (triploidy 69, tetraploidy 92 – lethal); Aneuploidy (not multiple of 23 – from nondisjunction); Trisomy (three copies of a chromosome – Down syndrome trisomy 21, 1 in 800 live births, risk increases with maternal age 35); Monosomy (one copy – more severe than trisomy); Turner syndrome (XO – female phenotype, short stature, webbed neck, no ovaries); Klinefelter syndrome (XXY – male phenotype, infertility) Mendelian Inheritance Genotype vs phenotype; dominant vs recessive; heterozygous vs homozygous; Penetrance; Autosomal dominant (50% recurrence risk – neurofibromatosis, Marfan syndrome); Autosomal recessive (25% recurrence risk – both parents carriers, PKU, cystic fibrosis); X-linked recessive (much more common in males – Duchenne muscular dystrophy, hemophilia A; carrier mothers have 50% chance affected sons, 50% chance carrier daughters) Multifactorial Inheritance Polygenic traits (multiple genes); multifactorial diseases (genes + environment – hypertension, coronary heart disease, diabetes, obesity, cancer, schizophrenia); empirical risks (based on direct observation) Epigenetics Chemical modifications without DNA sequence change; DNA methylation (methyl group to cytosine – silences genes); histone modification (acetylation, methylation); non-coding RNAs (miRNAs); X-inactivation; role in cancer (altered tumor suppressor genes, proto-oncogenes) Teratogens & Fetal Development Fetal alcohol syndrome (cognitive abnormalities from ethanol exposure – altered methylation); TORCH infections (Toxoplasmosis, Other – EBV/VZV, Rubella, Cytomegalovirus, Herpes); Period of organogenesis (15-60 days post-conception – most vulnerable) Stress Response General Adaptation Syndrome (GAS – alarm, resistance, exhaustion); Homeostasis; Allostatic load (cumulative effects of stressors); Allostatic overload (exaggerated responses leading to disease); HPA axis (hypothalamus → CRH → anterior pituitary → ACTH → adrenal cortex → cortisol); Sympathetic nervous system (adrenal medulla → catecholamines – epinephrine, norepinephrine); Cortisol effects (mobilizes glucose, amino acids, lipids – inhibits inflammation, immunosuppressive with chronic elevation); Epinephrine (increases cardiac output, bronchodilation, hyperglycemia); Norepinephrine (vasoconstriction, increased BP, alertness); Chronic stress alters adaptive functions – increases risk of obesity, metabolic syndrome, CVD, Alzheimer's, depression, schizophrenia, PTSD Epidemiology & Prevention Prevalence vs incidence; mortality vs morbidity; sensitivity vs specificity (higher percentage = better test at picking up disease); positive predictive value vs negative predictive value; false positives (stress, inappropriate treatment); false negatives (missed diagnosis); Primary prevention (prevent disease from occurring); Secondary prevention (detect disease early); Tertiary prevention (prevent further deterioration) Key Terminology Etiology (cause of disease); Pathogenesis (development of disease); Acquired (develops after birth); Congenital (present at birth); Genetic (inherited); Nosocomial (result of hospital stay); Iatrogenic (result of medical treatment) Key ABG Interpretation Problems Solved: ABG Values Interpretation pH 7.52, pCO2 40, HCO3 31 Uncompensated metabolic alkalosis pH 7.33, pCO2 29, HCO3 16 Partially compensated metabolic acidosis pH 7.4, pCO2 40, HCO3 24 Normal pH 7.12, pCO2 60, HCO3 29 Partially compensated respiratory acidosis pH 7.48, pCO2 30, HCO3 23 Uncompensated respiratory alkalosis pH 7.62, pCO2 47, HCO3 30 Partially compensated metabolic alkalosis pH 7.30, pCO2 59, HCO3 28 Partially compensated respiratory acidosis Why This Guide Works: 653 Q&A – Most comprehensive NURS 6030 study guide available Complete solutions – Every question answered with detailed explanations ABG mastery – ROME method with practice problems Genetics coverage – Mendelian inheritance, chromosomal disorders, epigenetics Fluid & electrolytes – Sodium, potassium, calcium disorders with mechanisms Stress response – HPA axis, catecholamines, cortisol, allostatic overload Perfect for: NURS 6030 Advanced Pathophysiology students Graduate nursing programs (NP, CNS, CNM, CRNA) Medical students and physician assistant programs NCLEX-RN and graduate-level nursing exams Anyone needing comprehensive pathophysiology review
