Cheat Sheet
- Major Components of Blood -
Blood is composed of plasma, red blood cells, white blood cells, and platelets, each performing vital roles like oxygen transport, immunity, and clotting (American Heart Association, 2022). Use the mnemonic "Never Let Monkeys Eat Bananas" to remember leukocyte order: Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils.
- Hematocrit and Hemoglobin Metrics -
Hematocrit (Hct) equals (RBC volume / total blood volume) × 100 and, along with hemoglobin concentration, helps diagnose anemia or polycythemia (CDC, 2021). Practice blood test questions using example values (e.g., Hct = 45%, Hb = 14 g/dL) to build confidence in interpreting lab results.
- Coagulation Cascade Essentials -
The coagulation cascade splits into intrinsic and extrinsic pathways that converge on Factor X to generate a fibrin clot (NIH, 2020). Remember "PEA": Prothrombin, Extrinsic, and Intrinsic arms - with PT and aPTT assays evaluating extrinsic (PT) and intrinsic (aPTT) pathways respectively.
- Arterial Blood Gas Analysis -
Assess pH, PaCO₂, and HCO₃❻ to distinguish respiratory versus metabolic imbalances using the "ROME" mnemonic: Respiratory Opposite, Metabolic Equal (Merck Manual, 2019). Incorporate these ABG interpretations into your blood practice questions to sharpen critical reasoning before a blood quiz.
- ABO and Rh Blood Typing -
Antigen - antibody interactions in the ABO and Rh systems dictate compatibility; remember O-negative as the universal donor and AB-positive as the universal recipient (American Red Cross, 2021). Drill quiz blood scenarios with crossmatch examples to ensure safe transfusion practices.
