About NR 283 Pathophysiology at Chamberlain
NR 283 is one of the most challenging courses in the Chamberlain nursing program. It covers disease processes at the cellular and systemic level. Understanding pathophysiology is essential for every nursing course that follows.
High-Yield NR 283 Topics
Cell Injury and Death
- Types of cell injury: hypoxic, chemical, infectious, immunologic
- Reversible vs irreversible cell injury
- Apoptosis vs necrosis — know the difference
- Types of necrosis: coagulative, liquefactive, caseous, fat, gangrenous
Inflammation and Healing
- Acute vs chronic inflammation — signs, mediators, outcomes
- Chemical mediators: histamine, prostaglandins, leukotrienes, cytokines
- Wound healing: primary vs secondary intention
- Factors affecting healing: nutrition, infection, diabetes, age
Fluid and Electrolyte Imbalances
- Edema — causes and types: pitting vs non-pitting
- Dehydration vs overhydration
- Sodium: hyponatremia (Na+ below 135) vs hypernatremia (Na+ above 145)
- Potassium: hypokalemia (K+ below 3.5) vs hyperkalemia (K+ above 5.0)
Acid-Base Balance
- Normal pH: 7.35-7.45. Acidosis below 7.35, alkalosis above 7.45
- Respiratory acidosis vs alkalosis — caused by CO2 changes
- Metabolic acidosis vs alkalosis — caused by HCO3 changes
- Compensation mechanisms — lungs compensate for metabolic, kidneys for respiratory
