A nursing-focused electrolytes cheat sheet for sodium, potassium, calcium, and magnesium. Includes quick ranges, clinical patterns, first actions, and NGN tie-ins - plus links to lab values, ABG interpretation, and practice cases. Understand what normal electrolyte levels mean for your body's essential functions.

Understanding the Context

Learn about key electrolytes and their ideal ranges. Electrolytes are an essential part of how your body functions, affecting everything from hydration to how your heart beats. They can also help doctors diagnose a wide range of medical conditions and problems. The values listed below are generalizations.

Key Insights

Each laboratory has specific reference ranges. Normal electrolyte ranges include sodium (135-145 mEq/L), potassium (3.5-5.0 mEq/L), chloride (96-106 mEq/L), and bicarbonate (22-28 mEq/L), which are crucial for maintaining proper cellular function, nerve transmission, muscle contraction, and acid-base balance in the body. Use this convenient cheat-sheet to help you monitor laboratory values related to fluid and electrolyte status, acid-base balance, and hematology. Remember, normal value ranges may vary according to techniques used in different laboratories. The normal range for serum electrolytes tests can vary slightly by age, health condition, and the lab’s reference values.
