Go beyond memorizing normal ranges. This module teaches you to interpret CBC patterns, calculate the anion gap, recognize electrolyte emergencies, and apply lab results to clinical decisions at the bedside.
Hemoglobin, MCV, WBC differential, platelet count — anemia classification and infection recognition
Sodium, potassium, chloride, bicarbonate, BUN, creatinine, glucose — the electrolyte story
Calculate and interpret the anion gap — the gateway to metabolic acidosis diagnosis
AST, ALT, ALP, bilirubin — hepatocellular vs cholestatic patterns
PT/INR, aPTT — when to use each, what they monitor, what's emergent
Lactate, procalcitonin, CRP — sepsis recognition from labs
Creatinine trend, BUN/Cr ratio, eGFR, AKI recognition
Hypo/hypernatremia, potassium emergencies, calcium and magnesium basics
ICU-level lab reasoning for RN and NP: anion gap with albumin correction, DKA potassium management, ABG 5-step systematic interpretation, AKI KDIGO staging, HIT recognition, coagulation crisis protocols, and critical care electrolytes (Mg, phosphate, ionized calcium, ammonia).
Hemodynamic Monitoring Fundamentals and the core ECG curriculum are included with RN and NP subscriptions. Advanced Labs Interpretation — covering advanced clinical reasoning for CBC, coagulation, ABG, DKA, AKI, and critical care electrolytes — is available as a $149 CAD one-time add-on.
The CBC contains the most common critical values in acute care: hemoglobin indicating transfusion need, platelet trends indicating HIT or DIC, and WBC differential distinguishing bacterial from viral infection. Nurses who interpret indices like MCV and understand the differential catch clinical deterioration earlier.
The anion gap (Na - [Cl + HCO3]) represents unmeasured anions in the blood. An elevated gap signals acid accumulation — from DKA, lactic acidosis, renal failure, or toxic ingestion — before the patient looks critically ill. Nurses who know the anion gap catch metabolic emergencies faster.
No. Advanced Labs Interpretation ($149 CAD one-time) covers advanced clinical reasoning for CBC mastery, anion gap with albumin correction, DKA lab patterns and potassium management, ABG 5-step interpretation, AKI staging, and critical care electrolytes. It extends the fundamentals into ICU-level decision support.
