Sudden Infant Death Syndrome (SIDS): RN Lesson
Sudden Infant Death Syndrome (SIDS)
Start
Bronchiolitis and Croup
Bronchiolitis (primarily RSV) involves viral invasion of bronchiolar epithelial cells causing necrosis, edema, mucus hypersecretion, and small airway obstruction.
Start
Bronchiolitis Obliterans
Bronchiolitis obliterans (BO), also known as obliterative bronchiolitis or constrictive bronchiolitis, is a form of irreversible obstructive lung disease caused by inflammation and progressive fibrosis of the small airways (bronchioles).
Start
Bronchopulmonary Dysplasia (Advanced)
Bronchopulmonary dysplasia (BPD) results from arrested lung development in premature infants exposed to supplemental oxygen and mechanical ventilation during the critical period of alveolarization (24-36 weeks gestation).
Start
Celiac Crisis

Start
Conduct Disorder
Conduct disorder involves structural and functional brain alterations including reduced gray matter volume in the prefrontal cortex and amygdala, decreased serotonin activity, and elevated cortisol reactivity.

Start
Diabetic Ketoacidosis
Diabetic Ketoacidosis: RN Emergency Management: historical RN/RPN lesson restored from legacy corpus.
Start
Early-Onset Neonatal Sepsis
Neonates have an immature immune system with deficient complement activation, reduced neutrophil chemotaxis and phagocytic activity, limited immunoglobulin production (primarily relying on transplacental maternal IgG), and poor opsonization.
Start
Hypoglycemia: Recognition and Emergency Treatment
Hypoglycemia: Recognition and Emergency Treatment — nursing assessment, priorities and management.
Start
Hypospadias
Hypospadias results from incomplete fusion of the urethral folds during weeks 8-14 of embryonic development, when androgens (primarily dihydrotestosterone) direct masculinization of the external genitalia.
Start
IBD: Crohn Disease Vs Ulcerative Colitis
Inflammatory bowel disease (IBD) encompasses two chronic, relapsing conditions: Crohn disease (CD) and ulcerative colitis (UC).
Start
Insulin and Hypoglycemia Nursing: Types, Peaks, Hypoglycemia Protocol and
Complete RN lesson on insulin therapy and hypoglycemia: insulin types and timing, hypoglycemia recognition, 15-15 rule, Somogyi effect, dawn phenomenon, and Canadian NCLEX-RN priorities.
Start
Insulin Pump
Continuous subcutaneous insulin infusion (CSII) via insulin pump delivers rapid-acting insulin analogs to mimic physiologic insulin secretion.
Start
Kawasaki Disease
Kawasaki disease (KD) is an acute, self-limited systemic vasculitis of unknown etiology that predominantly affects children under 5 years.
Start
Necrotizing Enterocolitis (NEC): Early
Necrotizing enterocolitis involves intestinal ischemia, bacterial invasion, and transmural necrosis of the bowel wall.
Start
Neonatal Care
Neonatal complications arise from the complex interplay between gestational maturity, birth-related physiological stress, and the immature organ systems of the newborn.
Start
Neonatal Respiratory Distress
Neonatal respiratory distress syndrome (RDS) results from developmental deficiency of pulmonary surfactant in premature infants, predominantly those born before 34 weeks gestation when type II alveolar pneumocytes have not yet produced adequate surfactant.
Start
Newborn of Diabetic Mother
In pregnancies complicated by diabetes mellitus, chronic maternal hyperglycemia exposes the fetus to elevated glucose levels that freely cross the placenta via facilitated diffusion (GLUT-1 transporters).
Start
Pediatric
The PAT is a rapid 30-second across-the-room assessment evaluating three domains.
Start
Pediatric Dehydration
Children have proportionally more total body water (TBW) than adults: neonates ~75% TBW, infants ~65%, compared to ~60% in adults.
Start
Pediatric Early Warning Score
Pediatric Early Warning Score (PEWS) systems provide a standardized framework for recognizing clinical deterioration in hospitalized children.
Start
Pediatric Fluid and Electrolyte
Pediatric fluid and electrolyte management differs fundamentally from adult management due to children's higher metabolic rate, greater body surface area-to-weight ratio, higher total body water percentage (75-80% in newborns vs 60% in adults), and immature renal concentrating ability.
Start
Pediatric Respiratory Distress: Croup, Epiglottitis and Bronchiolitis
Pediatric airways differ significantly from adult airways, making children more vulnerable to respiratory distress.
Start
Pediatrics (Neonatal Care, Congenital Disorders, Immunizations)
Neonatal adaptation to extrauterine life encompasses the immediate physiological transitions at birth and the detection and management of congenital anomalies that affect newborn outcomes.
Start
Plastic Bronchitis
Plastic bronchitis is a rare condition characterized by the formation of large, branching fibrinous or mucoid casts that occlude the tracheobronchial tree, causing acute respiratory distress and potentially fatal airway obstruction.
Start
Subglottic Stenosis
Subglottic stenosis is narrowing of the airway in the subglottic region — the area between the vocal cords and the inferior border of the cricoid cartilage.
Start
Superior Mesenteric Artery Syndrome
Superior mesenteric artery (SMA) syndrome is a rare vascular compression disorder in which the third portion of the duodenum is compressed between the SMA anteriorly and the aorta and vertebral column posteriorly.
Start
Tracheomalacia
Tracheomalacia is characterized by excessive dynamic collapsibility of the trachea due to weakness, softening, or malformation of the tracheal cartilage rings and the pars membranacea (posterior membranous wall), causing dynamic airway obstruction particularly during expiration when increased…
Start
Trisomy 21 (Down Syndrome)
Trisomy 21 occurs when nondisjunction during meiosis produces a gamete with an extra chromosome 21, resulting in 47 chromosomes instead of 46.
Start
Wilson Disease
Wilson disease is an autosomal recessive disorder of copper metabolism caused by mutations in the ATP7B gene encoding a copper-transporting ATPase in hepatocytes.
Start
