The library

Grouped by system. Anything stamped in red can hurt a patient — read those first.

Fundamentals

Fluids, electrolytes, acid–base, safety

Potassium Imbalance

The electrolyte most likely to stop a heart. Narrow range, fast consequences, and the single most dangerous administration error in nursing.

Cardiovascular

Perfusion, rhythm, heart failure

CardiovascularHigh yield

Heart Failure

A pump that cannot keep up. Which side fails determines where the fluid backs up — and that one idea explains nearly every sign you will assess.

11 min1 critical

Respiratory

Gas exchange, airway, ventilation

Respiratory

Asthma and COPD

Both obstruct airflow on exhalation. One is reversible and episodic, the other is progressive — and that distinction changes everything about management.

Renal

Filtration, AKI, dialysis

Renal

Acute Kidney Injury

Sorted by where the problem sits relative to the kidney — before, within, or after. That location drives the entire management plan.

Endocrine

Glucose regulation, thyroid, adrenal

EndocrineHigh yield

DKA and HHS

Two hyperglycaemic emergencies that look similar at the bedside and are managed on the same skeleton — with one potassium trap that catches everyone.

Multisystem

Shock, sepsis, burns, trauma

MultisystemHigh yield

Sepsis and Septic Shock

Infection that turns systemic. Recognition speed determines survival more than any single intervention that follows.
