Foundations
The cross-cutting physiology every disorder page assumes: fluid and electrolyte balance, acid–base compensation, the shock states, and the sepsis cascade. Master these first — they are the highest-yield NCLEX concepts and the lens for reading every other system.
Fluid & Electrolyte Imbalances
High-yield in researchSodium, potassium, calcium, magnesium derangements and volume overload/deficit — ECG changes and the K⁺ safety rules.
Acid–Base Imbalances & ABGs
ABG High-yield in researchMetabolic vs respiratory acidosis/alkalosis, compensation, and a reliable ABG-reading method.
Shock States
High-yield in researchHypovolemic, cardiogenic, distributive, and obstructive shock — stage recognition and fluids-vs-pressors logic.
Sepsis & Septic Shock
High-yield in researchThe dysregulated infection response — subtle early cues, lactate, and the hour-1 bundle.
Inflammation, Infection & Healing
in researchLocal vs systemic inflammation, SIRS criteria, and the phases of wound healing.
Cellular Adaptation & Injury
in researchAtrophy to neoplasia — the vocabulary layer for oncology and degenerative disease.
