Cheat Sheet
- Osmotic Pressure and Fluid Shifts -
Electrolytes control fluid balance by creating osmotic gradients that drive water movement between compartments; remember the van 't Hoff equation (π = iMRT) to estimate osmotic pressure. This principle underpins many human body fluid balance questions and is frequently tested in a fluid balance quiz. A quick mnemonic is "MIRT" (Molarity, i-value, R constant, Temperature) for recalling the formula.
- Sodium-Potassium Pump Dynamics -
The Na❺/K❺-ATPase actively moves 3 Na❺ out and 2 K❺ into cells, using 1 ATP, to maintain membrane potential and regulate cell volume (American Physiological Society). Understanding this pump is key for any electrolyte true false quiz question about active transport. Tip: think "3 up, 2 in, ATP's win" to remember the stoichiometry.
- Intracellular vs Extracellular Water Distribution -
About two-thirds of body water resides in the intracellular fluid (ICF) and one-third in the extracellular fluid (ECF), which splits into plasma (~20%) and interstitial fluid (~80%). This ratio is vital for naturally occurring fluids quiz items on compartment volumes. Visualize a pie chart splitting ICF and ECF to solidify these percentages.
- Key Electrolyte Concentrations and Homeostasis -
Normal plasma sodium (135 - 145 mEq/L), potassium (3.5 - 5.0 mEq/L), calcium (8.5 - 10.5 mg/dL) and magnesium (1.7 - 2.2 mg/dL) ranges are core facts for human body fluid balance questions (NIH Clinical Center). Deviations signal disorders like hyponatremia or hyperkalemia. Use the phrase "Na-Ka-Ca-Mg" to recall the order from highest to lowest normal plasma concentration.
- Common Fluid Imbalances and Clinical Implications -
Dehydration, overhydration, hyponatremia and hypernatremia illustrate how electrolyte disturbances disrupt fluid balance and organ function (Journal of Clinical Nutrition). Practice with a fluid balance quiz to recognize signs like confusion or edema linked to these imbalances. Remember "SALT LOSS" (Sweating, Aldosterone low, Loop diuretics, Thyroid issues, Liver failure, Overhydration, SIADH, Skin burns) to recall hyponatremia causes.
